Product Specification

Astm Hot Rolled Galvanized Steel Sheet Zinc Coated GI Sheet Supplier

Hot Dipped Galvanized Steel Sheet are produced for applications where corrosion resistance is important. Zinc coating extends the life of the final product and is ideal for manufacturers. The attractive surface finish also makes consumers satisfied.

Hot dipped GI steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process.

The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly

adhered to the steel through the formation of an iron-zinc alloy bonding layer. This bonding layer is formed

by a diffusion process while the heated steel is in contact with molten zinc. Chesterfield can provide hot dipped

galvanized steel sheet & coil to meet your ASTM requirements with customer-driven surface finish options.

WHAT IS SPANGLE ON GALVANIZED STEEL?

In previous steel making generations, galvanized steel sheet used to contain large, flowery crystalline patterns of zinc on the surface of the steel known as "spangle". Spangle resembles large hexagonal snowflakes. Although today’s galvanized steel still contains spangle, modern steel mills produce galvanized steel with spangle that is virtually undetectable to the naked eye. This is known as minimum spangle and zero spangle galvanized steel.

Galvanized steel is used extensively across a wide range of industries due to its many advantageous properties,

which include:

• Low upfront cost
• Durable
• Resistance to rust

Application

Hot dipped galvanized steel is used in industries such as HVAC, construction, roofing, appliances, container, waste, and the automobile business to name a few. For example, in the HVAC business, galvanized steel sheet, coil, and slit coil (like 5.394” wide) are used to manufacture duct and spiral duct. Galvanized steel can either be pre-painted, post painted, or bare.

Galvanized steel is extensively used in construction, furniture, home appliances, and automobile industry due to its versatility and durability.

Automobile industry – About 80% of the car body is made of galvanized steel because of its anti-corrosion. it is also used to make shells, roofs, and floors of carriages, containers, etc.

Light industry, includes the casing of home appliances, chimneys, kitchenware, etc. It can be also found in agricultural uses or furniture industry, such as granary, billboard, etc.

Construction industry – Due to its light weight and durability, galvanized steel has been popular for over a century as building materials, especially for roofing and wall uses. Besides, it is also widely used in fencing, grilles, gutters, rolling doors, pipes, etc.

Hot dipped galvanized steel sheet have excellent performance, zinc spangle and coating can be controlled strictly. They are mainly used for building roof door; window, roller shutter door and lightgage steel joist For automobile industry, vehicle shell, chassis, trunk lid, oil tank, and fender; metallurgy steel sash back, and electric equipments, such as refrigerator base and shell, and kitchen equipments, color coated steel baseplate etc.
