Hot dip galvanization as we all know is a process that involves coating iron and steel with a layer of molten zinc so that they become rust free. Catering the small requirements involved during these processes and looking after the nitty-gritty involved in it, Tanya Galvanizers are one of the popular known hot dip galvanizing consultants of India. Let us peep into how it addresses every big and small aspect in order to provide premium solutions to the clients. Below stated are some questions that are adhered by Tanya Galvanizers in providing best services to clients.

  • Why does the galvanized coating thickness depend on the steel thickness?

    In order to create a perfect galvanized coating, it is necessary that iron and zinc are in proportion in a way that they diffuse into one another and are able to create galvanized coating. So, in cases when more iron is taken to react with zinc, one may end up with a thin coat. It is said that a thicker coating can be developed if the steel pieces are thicker as well. Moreover, steel along with phosphorus and silicon plays a vital role in enabling a galvanizing reaction as the galvanized coating thickness is highly dependent on the overall steel chemistry and its thickness.

  • Is hot-dip galvanized steel considered anti-sparking?

    Hot dip galvanized steel are non combustible and anti sparking. The reason behind this is very simple – major coatings are done with zinc. But of course, everything has an exception and same applies here as well that if zinc coating alloys have 30 to 55 % aluminum or if it is penetrated all the way down to the base steel when galvanized steel is struck very hard – there are high chances that the steel could spark!


  • Is it safe for food to be in contact with galvanized steel?

    Yes, the contact of food with galvanized steel is considered to be perfectly safe in case of majority of food items. Care should be taken in case of acidic foods as per the norms set by U.S. Food & Drug Administration as it may happen that the acid of the food may react with zinc forming salts which when consumed can cause mild sickness.

  • What type of materials will not galvanize?

    One can find various materials on which galvanized coating won’t be developed. As we all know, for a galvanizing reaction to occur, the much needed metal is iron. Apart from that, if you try to galvanize copper or aluminum, the coating won’t be formed. Additionally, other metals like 400-series stainless steel can’t be galvanized and though chrome-molly steel may develop a coating but will comprise of many bare areas.

Hence, gaining the recognition as one of the best galvanizing plant manufacturers, Tanya Galvanizers who has in-depth solutions and understanding about the hot dip galvanizers, should always be resorted to in case of any kind of galvanizing requirements.
