914mm–1250mm Regular Spangle Hot Dipped Galvanized Steel Coil SGCC DX51D for Construction and Container Applications

１．Product Overview

914mm–1250mm hot dipped galvanized steel coils are produced for construction materials, container manufacturing, roofing systems, household appliances, automotive components, and industrial fabrication. The zinc coating provides corrosion protection while maintaining the formability required for roll forming, bending, stamping, and profiling.

The product is manufactured according to JIS G3302, ASTM A653, and EN 10147 standards and is available in SGCC, SGCD, SGCE, SGCH, DX51D, and DX53D grades to support different processing and strength requirements.

２．Technical Solution

The steel substrate is continuously coated through a hot dip galvanizing process, forming a zinc layer that protects the steel surface from atmospheric corrosion and extends service life in indoor and outdoor environments.

Surface treatments such as passivation, chromating, oiling, and anti-finger coating can be applied to improve storage performance and reduce the risk of white rust during transportation and fabrication.

Multiple spangle options are available to meet appearance and downstream coating requirements.

３．Specifications

４．Application

The product is commonly used for roofing sheets, wall panels, garage doors, modular housing, soundproof walls, structural building components, containers, industrial equipment, refrigerators, air conditioners, electrical cabinets, fuel tanks, mufflers, agricultural buildings, silos, greenhouse systems, heat exchangers, and insulation-related applications.

５．Processing

The coils support slitting, cut-to-length processing, roll forming, bending, profiling, punching, stamping, and fabrication.

Customized dimensions, coating weights, hardness levels, and surface treatments can be supplied according to project requirements.
