Z275 Hot Dipped Galvanized Steel Plate Zhishang Steel Galvanized Sheet Plate

Zhishang Steel Galvanized Sheet Plate description

I. Core Characteristics of Z275 Hot-Dip Galvanized Steel Sheet

    1. Coating definition and process

      Z275 indicates that the total weight of the double-sided galvanized coating is 275 grams per square meter (137.5 grams per square meter on one side), which belongs to the hot-dip galvanizing process (SGCC).

.     The coating thickness is approximately 19.26 microns. By immersing the steel plate in molten zinc liquid (about 460°C), a dense zinc-iron alloy layer is formed, which has excellent corrosion resistance and mechanical properties.

    2. Technical parameters

      Material: The base material is mostly low-carbon steel (such as S420GD high-strength steel), with a yield strength of over 420MPa, suitable for load-bearing structures.

      Specification: Thickness range 0.3-3.0mm, width 700-1830mm. Customized processing is supported (such as uncoiling, slitting, etc.).

      Surface treatment: Zinc-free flower, small zinc flower or anti-fingerprint treatment are available to meet the anti-rust and aesthetic requirements of different scenarios.

    3. Performance advantages

      Corrosion resistance: It can last up to 50 years in Marine environments and over 20 years in industrial environments, far exceeding the lifespan of ordinary galvanized steel plates (such as Z100).

      Processability: Suitable for bending, stamping, welding and other processes. Especially when combined with concrete, the closed die design can enhance the structural stability.

Ii. Main Application Fields

    Z275 galvanized steel plates are widely used in the following industries:

    1. Field of architecture

      Steel structure workshops, roofs, ventilation ducts, roller shutters, etc. (accounting for 35% of market demand).

      Profiled steel sheets (such as YXB65-185-555B) are used for load-bearing floor slabs or walls, and are combined with high-strength steel to enhance building safety.

    2. Automobiles and Transportation

      Body parts, containers, and structural components of rail vehicles, taking advantage of their lightweight and corrosion-resistant properties.

    3. Household appliances and industrial equipment

      Air conditioner casings, washing machine panels, elevator components, etc., have both anti-rust and aesthetic requirements.

    4. Others: Chemical equipment, solar brackets, agricultural machinery, etc.
