22 Gauge ASTM A653 SGCC GI Steel Sheet Hot Galvanized Plain Steel Sheet for Building Materials and Appliances

22 Gauge ASTM A653 SGCC GI Steel Sheet Hot Galvanized Plain Steel Sheet for Building Materials and Appliances

１．Product Overview

22 gauge ASTM A653 SGCC GI steel sheet is a hot galvanized plain steel sheet used for building materials, home appliance shells, automobile components, vehicle brackets, steel vessels, cabinets, welded pipes, roof panels, and general fabrication.

The product is manufactured from SGCC or DX51D+Z galvanized steel substrate. Zinc coating from 30g/m² to 275g/m² provides corrosion protection, while big spangle and regular spangle surfaces support different appearance and processing requirements.

２．Technical Solution

The galvanized steel strip is produced through hot dip galvanizing, where the steel substrate is coated with zinc to improve corrosion resistance.

Chromate passivation helps reduce surface oxidation during storage and transportation. Regular spangle surface is suitable for general galvanized applications, while big spangle provides a more visible galvanized crystal pattern.

The product can be supplied according to GB, JIS, DIN, EN, and ASTM standards for construction, appliance, automotive, and industrial use.
