SGCC SGCD JIS G3302 Hot Dipped Galvanized Steel Strip Coils Z30-Z275 for Welded Pipe and Construction

SGCC SGCD JIS G3302 Hot Dipped Galvanized Steel Strip Coils Z30-Z275 for Welded Pipe and Construction

１．Product Overview

SGCC SGCD JIS G3302 hot dipped galvanized steel strip coils are used for welded pipes, greenhouse pipes, gas pipes, heating pipes, construction roof panels, roof grilles, home appliance shells, kitchen utensils, automotive corrosion-resistant parts, refrigeration processing, storage systems, and packaging applications.

The product is supplied according to ASTM A653, JIS G3302, and EN10147 standards. Zinc coating options from 40g/m² to 275g/m² provide corrosion protection for industrial and construction applications, while regular and big spangle surfaces support different galvanized appearance requirements.

２．Technical Solution

The steel strip is coated with zinc through continuous hot dip galvanizing to form a protective metallic layer on the steel surface.

Passivated and chromated treatment helps reduce oxidation during storage and shipment. Oiled surface treatment provides temporary rust protection and supports downstream fabrication.

The product can be supplied in steel coil form with 508mm or 610mm coil ID according to customer processing requirements.

３．Specifications

４．Application
