There are various types of hot-dip galvanized crash barriers available in the market by various manufacturers. They are majorly used on the side of roads or highways so that there are fewer chances of accidents. There are various advantages of hot-dip galvanized crash barriers and some of them are being elaborated below.
A galvanized crash barrier is much more durable than any other form of painting done on them. This is due to uniform protection, complete coverage and abrasion resistance. The intermetallic layers formed on galvanized steel are bonded metallurgically and are harder than base steel. The top layer of pure zinc can absorb impact and is very ductile. All these zinc layers are abrasion resistant.
The zinc coating grows parallel on the steel which is the reason why both edges and corners have the same thickness as that of flat surfaces. The total immersion process furthermore makes sure that the tubular and hollow structures are protected both outside and inside. The uniform coverage ideally means that the corrosion cannot happen easily on the surface.
A crash barrier which is galvanized is corrosion resistant. It does not get rusted easily due to weather or any other external environmental factors which makes it look new and shiny every time. Hot-dip galvanization provides three levels of corrosion resistance to steel which are cathodic protection, barrier protection and zinc patina.
The steel is first isolated from the environment by providing basic barrier protection. The layers of zinc are tightly bonded on the steel base which makes the damage difficult. Cathodic protection means that even if the coating gets destroyed the surrounding zinc will still protect the steel from corrosion.
Zinc patina is a layer formed by zinc when it is exposed to the environment so that the corrosion rate is narrowed down and an additional environmental barrier is formed. When this layer gets fully developed the corrosion of the steel reduces to a greater degree.
Availability and Versatility
Hot-dip galvanization is available in almost all parts of the world and it can be stored easily for a long time before making crash barriers. The elements used in hot-dip galvanization are readily available due to which it is preferred over other forms of painting.
Hot-dip galvanized steel is made from the harshest materials available in the environment due to which it lasts longer. The corrosion of the steel takes place at a slower rate as compared to other forms of steel paintings.
Zinc is available in abundance in water, air, earth and soil. It is essential to all the living beings and both steel and zinc are fully recyclable without losing their properties which makes galvanized steel a renewable material. The steel has no harmful impact on the environment when compared to other forms of painting.
Thus, we see that hot-dip galvanized crash barriers have many benefits. If you are confused about whether to go for hot-dip galvanization or painting always choose hot-dip galvanization. At Tanya Galvanziers, we make sure that you get quality galvanized barriers which are pocket friendly and last long.
