Wholesale Hot Dipped Galvanized Steel Coil

Hot-dipped galvanized steel coil is a product made by passing cold-rolled steel coil through a molten zinc bath to coat it with a thin layer of zinc to provide corrosion resistance and protect the underlying steel from rusting. The process of hot-dip galvanizing creates a metallurgical bond between the zinc coating and the steel substrate, resulting in a durable and long-lasting coating. Hot-dip galvanized coatings are typically thicker than electro-galvanized coatings, ranging from 50 to 150 microns or more. 100% Factory Low Price. Fast Shipping And Delivery. Free Samples Provided.

Features of Wholesale Hot Dipped Galvanized Steel Coil

The zinc coating on hot-dipped galvanized steel provides excellent corrosion resistance, especially in harsh environments. This makes it ideal for outdoor use, where the steel is exposed to moisture, chemicals, and other corrosive elements. Typically, the zinc coating on hot-dipped galvanized steel is thicker and provides better corrosion protection, making it suitable for outdoor applications and environments with high humidity or exposure to corrosive elements.

The zinc coating also provides a durable surface that can withstand harsh environments and mechanical wear, making hot-dipped galvanized steel coils long-lasting and reliable.

Galvanized steel is typically stronger than regular steel, thanks to the bonding of the zinc coating to the steel surface. This makes it suitable for applications where strength and durability are important, such as in construction and manufacturing.

The shiny, metallic appearance of hot-dipped galvanized steel can enhance the visual appeal of products and structures, making it a popular choice for architectural and decorative applications.

Hot-dipped galvanized steel is easy to work with and can be welded, bent, and formed into various shapes without damaging the coating, making it suitable for a wide range of manufacturing processes.


Hot-dipped galvanized steel coil is widely used in construction, automotive, and manufacturing industries for applications such as roofing, siding, ductwork, automotive parts, and agricultural equipment. It is valued for its corrosion resistance, durability, and ability to withstand harsh environmental conditions.
