Galvanized Steel Coil

Product description
Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Galvanized Plate Metal is a type of steel that has been treated with an application of protective zinc coating to help prevent it from rusting. Galvanized Steel Sheets are also easy to weld, form, and drill. With a typical protection life span of 20 years.Galvanization is the process that is used to apply the zinc to the steel through the use of electrochemical and electrodeposition processes. The steel parts are submerged into a vat of hot, molten zinc to form a protective coating.The most common means of galvanizing the steel available today is through what is known as hot-dip galvanization.Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Zinc Coated Steel Plate is widely used in applications where rust resistance is needed. Galvanized steel can be welded however, you should exercise caution around the resulting fumes.
Hot Dipped Galvanized Steel Plates are excellent candidate for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized hot rolled steel, or mild steel, sheets have been dipped into a molten zinc coating, or zinc-iron alloy-coated (galvannealed) by the hot-dipped process (ASTM A653). Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as “spangle” on the surface of the material. Great corrosion resistance, excellent candidate for outdoor use or exposed environments. Common applications include HVAC, flashing, freezers, commercial and architectural uses, electrical boxes, enclosures and housings.
Applications of thin Gi Plate:
1. Construction: roof and roof component, outside walls of civilian and industrial buildings, garage doors and window blinds.
2. Houshold appliances: washing machine, refrigerator, television, air conditioner and ventilation system, Vacuum cleaner, solar water heater.
3. Transportation: car ceiling, auto Industry Muffler, heat shields of exhaust pipe and catalytic converter, the ship bulkhead, highway fence
4. Industry: industrial Instruments Electric control cabinet, industrial refrigeration equipment, automatic vending machine
5. Furniture: lampshade, counter, signboard and medical facility etc.
