Frequently Asked Questions About Galvanizing
Galvanizing involves applying a special zinc coating over iron or steel for protection, preventing rust accumulation. Hot-dip galvanization, the most common galvanization technique, involves dipping steel parts in molten zinc. Take a look at these frequently asked questions about galvanizing the next time you are considering these products and services:
What is Hot-Dip Galvanizing? This common process is a type of galvanization that coats iron, steel or aluminum with a thin layer of zinc via immersion of the metal in molten zinc at 860 degrees. Why? This process is designed to avoid both corrosion and rust formation. Galvanized steel is often used when the possibility of rust is a high concern.
Do You Provide Electroplating and Plating? Electroplating is a common plating process involving a solution of metal ions that coats an electrode using electrical current and moving by an electrical field to cut down on cations from a solution. This coats the conductive metal item with a thin layer for the purposes of abrasion. Plating involves depositing a metal onto a conductive metal surface to decorate objects, improve wearability, prevent corrosion, cut down on friction and improve paint adhesion of paint.
Do You Offer Powder Coating? Many companies in the galvanizing business offer powder coating, which is applied as a free-flowing, dry powder, as opposed to a liquid coating requiring a solvent. Powder coatings, applied in an electrostatic process, are cured under heat to form a thin layer of protection. This common process is used to coat many different metals for anything from household appliances to automobile parts.
Dealers that will galvanize metals can be found by searching the internet or looking in a phone book. You can call and ask if they offer hot dip or cold galvanized steel. Some companies will specialize in some areas and not others. Therefore, call the company and ask if they offer nickel plating, stainless steel coatings, zinc layering on aluminum alloy or iron, or anything else you may be looking for. Fabrication of steel has many different requirements, as does welding galvanized steel, which is why hiring a professional to do the job is important. Plate strips, coil coating, electro-galvanizing or galvanizing bolts and wires will range in price depending on the dealers. Shop around to see where you can get the best deal for galvanized plates. Ask how long the company has been in business and if they offer any discounts for large purchases if you have a large order to fulfill. Ask how much sheets of different materials are and compare with other companies you speak with. You may be able to visit the company and take a look at the process yourself and see the fasteners they use and the processes they do for cold and hot dip galvanized steel. Any type of metal, including zinc and copper can be used for coating other types of metal depending on how it will be used. You can often speak with a professional to see what the best option is for what the metal is to be used for. Take into consideration their customer service department in case you have any questions or complaints in the future.
