Crash Barrier: Essential for Roadway and Construction Site Safety

Posted on by

What is a Crash Barrier?

Crash barrier are engineered safety structures that prevent vehicles from veering off the road or colliding with dangerous obstacles. These barriers are a critical line of defense, keeping cars on course and providing controlled redirection during accidents. Used extensively along highways, bridges, and construction zones, crash barriers protect motorists from hazards like steep slopes, water bodies, and oncoming traffic. By absorbing and redirecting impact energy, crash barriers minimize the risk of severe accidents, safeguarding drivers and roadside structures.

Galvanizing of Crash Barriers

Galvanizing crash barrier involves coating them with zinc to enhance their durability and corrosion resistance. Since outdoor elements like moisture, temperature fluctuations, and pollutants constantly expose crash barriers, galvanizing offers a protective layer that shields the underlying steel from rust and degradation. Hot-dip galvanizing is the preferred method, as it ensures a robust bond between the steel and zinc coating, which is essential for long-lasting, low-maintenance barriers. Galvanized crash barriers withstand extreme weather conditions and maintain structural integrity over time, offering reliable protection across various terrains.

Types of Crash Barrier

Crash barrier come in various designs, each suited to specific applications and environments:

1. Roadside Barrier

 Roadside barriers are placed along roadway edges to prevent vehicles from colliding with obstacles or leaving the   road. These Crash barriers are beneficial in areas with nearby slopes, water bodies, or other dangerous obstructions.

 2. Median Barrier

 Median barriers are located along the center of highways to separate opposing traffic lanes. Engineers specially designed these crash barriers to absorb and dissipate impact energy, which reduces the likelihood of crossover collisions and prevents vehicles from crossing into oncoming lanes.

3.Bridge Barrier

 Bridge barriers are positioned along the edges of bridges to protect vehicles and pedestrians from falling off. They   are typically taller than standard roadside barriers and engineered to withstand higher impact forces, preventing   cars, trucks, and cyclists from crossing over into dangerous areas below.

4.Work Zone Barrier

Workers install temporary structures called work zone barriers to safeguard construction sites and redirect traffic. They can consist of concrete, plastic, or metal and are often modular for easy relocation. Work zone barriers are vital in reducing accidents in high-risk areas where workers and moving machinery are present.

5.Flexible Barrier

Flexible barriers like cable are designed to flex when impacted, absorbing kinetic energy over a longer distance. This  crash barriers prevents light vehicles from going off-road, making it suitable for low-speed zones and areas requiring minimal visual obstruction.

6.Rigid Barrier

Rigid crash barriers, usually reinforced concrete, do not absorb impact energy. Instead, they are intended to redirect  vehicles away from hazards. While these barriers offer maximum containment, they are less forgiving than flexible  options, making them suitable for locations where space constraints limit barrier placement options.

Role of Crash Barriers in Protecting Construction Sites

Crash barrier are integral to construction site safety, serving multiple roles in minimizing accidents and ensuring smooth traffic flow. Construction sites, especially those near roads, are high-risk zones where workers and motorists need protection from potential hazards. As a physical shield, crash barrier create a safe boundary that separates construction activities from moving traffic, reducing the likelihood of worksite intrusions and vehicle collisions.

Crash barriers play a vital role in construction zones by serving as visual markers, guiding drivers safely through temporary detours and lanes. This is especially critical during nighttime or adverse weather conditions when visibility is poor. The enhanced visual cues provided by crash barrier help prevent confusion and keep traffic flowing smoothly. Beyond guidance, crash barriers absorb and redirect impact forces, significantly reducing the severity of accidents near construction areas. This dual function not only ensures a safer environment for motorists but also protects workers and equipment, making them indispensable for construction site safety.

Conclusion

Crash barrier are vital in enhancing road safety and protecting construction sites. Galvanized crash barrier benefit from improved durability and corrosion resistance, making them suitable for various terrains and weather conditions.

A Step-by-Step Guide to Maintaining Zinc Galvanized Steel

Posted on by

Hot-dip galvanizing is the finest process that helps maintain sustainability for the materials to produce corrosion resistance. Galvanizing work is performed by immersing iron or steel in a bath of hot molten zinc. The reaction that develops in the entire process is forming a coat on the surfaces to create a firm, thick layer on the steel. 

FACTORS AFFECTING THE SHELF LIFE OF THE GALVANIZED STEEL GRATING.

Certain factors increase the durability and effectiveness of galvanized steel gratings. The core factors include high-quality galvanization, the environment in which installers place gratings, the frequency of the materials present, and the level of corrosive raw materials available.

The galvanization process demands thorough work, which involves coating steel with a layer of molten zinc, which adds additional protection to the materials. However, weather conditions can naturally and physically compromise the integrity of the level of these protective layers.    

Today, the idea of discussion on the blog is to share a full-fledged guide which helps maintain “zinc galvanized steel”.

Regular Cleaning

Zinc galvanized steel demands regular cleaning when it comes to maintaining it. The main reason for this is that these zinc galvanized steel will have dirt, dust, and grime that later time will decrease the potential of the material, leading to rust and corrosion.

Thus, it is necessary to maintain a time for regular cleaning with the help of a brush to remove all the loose particles. Cleaning this can be done with mild soap and warm water. Once the process is complete, let it dry, and later on, apply the chemical to moisten the surface so that it can have longevity and avoid damage to the galvanized coating.

Inspection for damage or wear

Regularly, a team of skilled staff must keep track of inspecting the damages that may occur on these zinc galvanized steel. Inspecting for damages is the crucial part; hence, the team must be more cautious to ensure they don’t leave any items behind. Additionally, the team needs to check welded joints regularly to avoid any significant harm in the future.. 

Repairing minor damages

If there are any small damages or minor changes, repairing the same can be done in-house with the help of the right tools and materials. This entire process includes applying sand to the damaged area. It continues with the need to use a rust-resistant primer and cover it up; painting over that area makes it richer. The painting of the area is done with the help of zinc-rich paint. 

Protecting against corrosion

To protect zinc galvanized steel from corrosion, applying a proper coating of protective paint is advisable. It helps create a barrier and shield on the steel bars to form a secured element with the segment to increase its lifespan.

Pre Galvanized Vs Post Galvanized

Pre-Galvanized vs. Post-Galvanized: Choosing the Right Approach

Posted on by

The process of choosing galvanization depends on the project that is undertaken. Overall, there are two types of galvanizing- batch hot-dip galvanizing and pre-galvanization. To understand the workflow, let us share the difference between pre-galvanized and post-galvanized. 

What is Pre-Galvanized?

Another name for pre-galvanized means “in-line”, ”continuous” or ”mill” galvanizing. It is an automated galvanizing process used for steel products such as steel sheets before they are cut into sizes and pieces to be processed. The best example to understand this is Duragal.

What is Post-Galvanized or Hot-Dip Galvanizing?

The hot-dip galvanizing process means involvement and immersing of steelwork, completed in molten zinc with a temperature of (830 F) and the material has 98% zinc.

To initiate the bath of the steel, it needs to lower down to an angle, allowing air to escape from a tubular shape or other pockets. Considering this, it will allow the melted zinc to flow into the tube properly and the entire section. With the immersive bath process, the steel’s iron material reacts with the zinc, forming a series of layers of zinc iron. On the other side, its outer layer is pure zinc. Undertaking this galvanizing method helps provide the perfect and ultimate corrosion protection for steel.

Factors to consider when deciding which method to use for substation structures.

The galvanization process plays a crucial role in the projects where the team is working on constructing substation structures. Here are the core points we would focus on knowing and understanding the factors associated with substation structures.
– Security of Supply.
– Maintainability.
– Operational Flexibility.
– Extendibility.

Differences Between Hot-Dipped Galvanization & Pre-Galvanizing

Differences Between Hot-Dipped Galvanization & Pre-Galvanizing

Posted on by

Galvanizing is one of the widely used methods for protecting metals from corrosion. It involves applying a thin zinc coating to a thicker base metal like iron metal. The process helps to shield the metal from the surrounding environment. When a metal undergoes galvanization, it does not experience any corrosion. However, without the zinc coating, the metal remains exposed to the elements and potentially oxidizes and corrodes faster. There are several ways of galvanizing metals, including hot-dipped galvanization and pre-galvanizing.

Hot-Dipped Galvanization vs. Pre-Galvanizing: What Are They?

As the name suggests, in hot-dipped galvanization, experts dip the steel in hot, molten zinc. When the zinc coats the steel, a metallurgical reaction occurs between the iron component of the steel and the hot zinc. The reaction known as the diffusion process occurs when the coating collects perpendicular to every surface, creating a uniform thickness.

When the expert removes the steel from the zinc bath, it reacts with the oxygen in the air to form zinc oxide. It then reacts with carbon dioxide and forms the final protective coating of zinc carbonate. With multi-layered zinc coating and iron-zinc alloy, the steel becomes corrosion-resistant.

Pre-galvanizing, also called mill galvanizing, is another galvanizing process close to ho-dipped galvanizing. However, this process occurs at the very first stage of production. The process takes place at steel mills that have a specific shape. Pre-galvanizing involves a few steps of hot-dip galvanizing, like cleaning the surface, hot zinc bathing, and recoiling.

Key Differences Between Hot-Dipped Galvanizing and Pre-Galvanizing

Differences Between Hot-Dipped Galvanization & Pre-Galvanizing

Application Comparison

Hot-dipped galvanization is an economical choice that you can execute on simple and complex shapes. Experts use it on objects fabricated beforehand and yet not galvanized. The hot-dipped galvanization plays the last step.

On the other hand, a metal requires undergoing pre-galvanizing at the first production stage. It mainly occurs at the mill and later undergoes cutting into size and fabrication.

Coating Comparison

Since the galvanizing process involves the application of a protective coating for the steel and metals, it is essential to consider the coating finish of the two methods of manufacturing galvanized steel.

Coating Thickness

Although both methods result in uniform thickness, the hot-dipped galvanization produces a thicker layer of protection than the other method.

Coating Continually

Hot-dipped galvanizing requires dipping the entire steel and other metals into the molten vat of zinc. The galvanized steel comes with a continuous coating over the surface. On the other hand, pre-galvanizing requires performing before cutting the sheets into perfect sizes and pieces; therefore, the cut edges do not undergo any coating.

Coating Formability

Since the process of pre-galvanizing undergoes at the mills, any coating applied after cutting the metals does not damage the layer. On the other hand, coating formability applied on hot-dipped galvanized steel is not advisable, as it might damage the protective coating of the products.

Coating Appearance

The hot-dipped galvanization forms a bright finish for the galvanized steel, which might or might not be uniform. On the other hand, the pre-galvanizing process produces a uniform bright finish for the coating.

There are numerous differences between hot-dipped and pre-galvanizing processes. Understanding the differences helps in choosing suitable methods and products for different projects.

Zinc Galvanizing for Sub Station Structures a must-Tanya Galvanizers

Zinc Galvanizing For SubStation Structures A Must

Posted on by

Substation structures are a set of complex equipment made metals consolidated together to ensure reduction of high voltage electricity. It is because of this reason substation structure are placed outside in open places with bare minimum shade covering, since it handles transmission flow. This placement of the substation structures in the open places results in its exposure to natural elements on a regular basis. This results in corrosion of the structure since they are made from metals. Further because of the substation structures primary function it handles a large amount of heat and energy exposure that also contributes to its corrosion. It is because of this reason it is extremely important for substation structure to have proper elementary coating on its metal surfaces in order to avoid corrosion.

The solution to this corrosion issue was defined through zinc galvanization process. Let’s take a look at what is Zinc galvanizing process and why it is a must for substation structures.

What is Zinc Galvanization Process?

Zinc galvanizing process is one of the most used application of galvanizing process. This process highlights coating a steel or iron object by submerging it into a bath of molten zinc. The bath of molten zinc showcases temperatures around 840°F (449°C). Once removed from the bath, the zinc coating on the iron or steel’s exterior reacts with oxygen in the atmosphere to form (ZnO) Zinc oxide. This Zinc oxide further reacts with carbon dioxide in the atmosphere to form a more compact protective layer known as (ZnCO3) Zinc carbonate. This Zinc carbonate reflects a dull grayish film, which is relatively stable and adheres tightly to the surface of the steel or iron. This results in the zinc galvanizing process to create a chemical balance, which ensures that the zinc is chemically bonded to the underlying metal and becomes part of the steel or metal that is being protected through the zinc galvanizing process.

Why Zinc Galvanization is Must for Sub Station Structure?

Substation structures are always exposed to natural elements that result in corrosion effect on the metals that are used to develop the substation. Further, with the substation structure continuously functioning with energy resource the corrosion effect increases overtime at a faster pace. Yet substations cannot be shut down because of the important transmission operational role it plays in managing energy. Further the metals used to develop the substation are of huge cost and value and corrosion can result in decay of the metal overtime resulting in rise of maintenance cost. It is because of this reason it is extremely important to zinc galvanize substation structure. Since zinc galvanization process will prevent the substation structure from corrosion and also safe guard it financially from huge losses that may happen because of decay in such costly metals. This in turn will allow substation structures to come across profound advantages.

Advantages of Zinc Galvanization on Substation Structure

There are many advantages that a substation structure can enjoy from zinc galvanization. They are as follow:

  • Prevention of metals from corrosion through exposure to natural elements
  • Prevention of metal decay from exposure regular energy transmission
  • Safeguard against huge financial losses because of metal decay and corrosion process
  • Lower the annual maintenance cost
  • One time investment because of zinc galvanization that can create protection for decades

It is because of these advantages that a substation structure can enjoy because of zinc galvanization, it is must for the structure to prevent any physical damages.

How Does Galvanization Of Steel Make It More Durable-Tanya Galvanizers

How Does Galvanization Of Steel Make It More Durable?

Posted on by

Concept of Galvanization

Galvanization of steel is nothing but a process of application of a protective zinc coating to the steel for making it more durable in nature. The most common method used in the process of galvanization of steel is hot dip galvanizing which involves of submerging the parts of steel in a molten zinc bath.

Steps Involved in the Process of Galvanization

Ii is clear that the process of galvanization involves the application of coating. At the time of applying coating, the most important step is the preparation of the surface.

Caustic Cleaning

To begin with the galvanizing services, the first step is caustic cleaning and as indicated by the name, it refers to the removal of several organic impurities like dirt, grease and oil from the surface of the steel by a hot alkali solution. Other unwanted substances like vinyl, asphalt, epoxies or welding slag is cleaned by mechanical means.

Pickling

It is a process of removing scale and rust from the surface of the steel with the help of hydrochloric acid in an appropriate temperature.

Rinsing

After the process of chemical cleaning is over, the steel is properly washed in water for the minimisation of transfer of acid residues to the following stages of galvanization.

Fluxing

Fluxing is the final step in the preparation of galvanizing process where all oxides are removed and further formation of oxides are prevented which promotes the bonding of the coating of zinc with the steel.

After the surface preparation of steel is complete, it is submerged in a molten zinc bath of approximate temperature of 830 degrees Fahrenheit containing about 98 percent pure zinc. Then the coated steel is taken out and cooled which concludes the process of galvanization.

Hot Dip Galvanizing Services-Tanya Galvanizers

How the Process Makes Steel More Durable

Hot dip galvanizing plays a crucial role in making the steel more durable in the following ways.

Resistant to Abrasion

The process of galvanization forms three abrasion resistant intermetallic layers and a top layer of pure zinc on the surface of the steel. This enables the steel to become more durable in nature which provides unparallel protection to the steel.

Protection is Uniform

Galvanizing provides uniform protection to the steel forming natural thick coating especially at the edges and corners that are more prone to damage. Therefore, the uniform protection leaves no weak points for being damaged or corroded.

Guidelines While Welding Galvanized Steel-Tanya Galvanizers

Guidelines While Welding Galvanized Steel

Posted on by

Hot dip galvanizing process is being used to safeguard iron & steel from getting rusted for centuries. It is actually a zinc coating over steel. Similar to paint, it safeguards steel from rusting. This is achieved by forming a barrier between the environment and the steel. However, galvanizing does take a giant step when compared to pain. It offers electrochemical protection to steel. As zinc is found to be electrochemically reactive when compared to steel, the galvanizing coating can prevent steel from getting rusted. Therefore, galvanized steel is considered to be a much superior product when compared to steel being provided with other coating types on it. Even if the coating gets damaged in service or while handling, it safeguards the steel. We provide hot dip galvanizing services at an affordable price. For more details call: 91 8000842648

Galvanized product welding

Welding is done on galvanized steel similar to welding bare steel of similar composition. With some modification, similar welding process, travel speed, amps, volts, etc. could be used, if the switch is created from uncoated steel to that of galvanized steel. This is until zinc coating is found to be unusually thick. It is important to consider the importance of hot dip galvanizing.

Difference between welding uncoated steel and welding galvanized steel is due to low vaporization temperature resulting from zinc coating. It is at 900 F that zinc melts and vaporizes at 1650 F. With steel melting at 2750 F & welding arc temperature being 15000 – 20000 F, zinc close to the weld vaporizes. Zinc is just gone as weld pool freezes.

Why galvanizing is not done after welding?

The question why not galvanize after fabrication and avoid the problem. Steel products are galvanized always after fabrication since no practical way is present to restore galvanizing effectiveness after welding. It is routinely that galvanizing after fabrication needs to be performed very carefully. Fabrication is to be cleaned with acid, which again is to be neutralized. Then the fabrication is to be immersed in liquid zinc pot at 900 F. Great care is to be taken to ensure that when fabrication is lowered into zinc, it is dry. This is because, trapped water may flash to steam, thus exploding zinc everywhere. Zinc easily flows out and into every nook and corner for achieving complete coverage. It is quite tough if tubes are used for creating fabrication, as tubes are to be open on both its sides to allow proper flow of zinc. Trying to achieve uniform coverage even with the simplest fabrication could prove to be difficult.

Finally, the fabricated product is to be fit properly into the molten zinc pot, which again can be a tough challenge especially by having large structures. It is much easier to galvanize sheets, plates, structural shapes, wires and tubes, prior to creating them into products. This is because they have simple shapes, without any crannies or nooks, no place to trap water or any hidden cavities.
