G90 SGCC ASTM A653 Galvanized Steel Strip 0.5mm × 50mm with Minimum Spangle for Container Plate

１．Product Overview

G90 SGCC galvanized steel strip is manufactured by hot dip galvanizing and is used for container plates, construction parts, roofing components, appliance panels, automotive parts, industrial cabinets, furniture parts, and general fabrication.

The product is supplied in 0.5mm thickness and 50mm width, with 120g/m² zinc coating and minimum spangle surface. The narrow strip format supports downstream forming, slitting, stamping, bending, and assembly operations.

２．Technical Solution

The steel strip is coated with zinc through a hot dip galvanizing process to provide surface protection against atmospheric corrosion.

Chromate-free passivation, oiling, or passivation plus oiling can be selected according to storage, shipment, and processing requirements.

The product supports ASTM A653, JIS G3302, and EN10346 grade systems, covering commercial quality and structural grade galvanized steel strip requirements.
