Tangsteel DX51D+Z Z275 High-Zinc Hot-Dip Galvanized Coil | Handan Steel SGCC Galvanized Steel Strip

Tangsteel DX51D+Z Z275 High-Zinc Hot-Dip Galvanized Coil | Handan Steel SGCC Galvanized Steel Strip

Shanghai Biying International Trade Co., Ltd. specializes in hot-dip galvanized steel coils (GI) from major steel mills, with long-term stable access to original resources from Baosteel, Angang, Magang, WISCO, Benxi Steel, Tangshan Steel, Shougang, and Handan Steel. Our standard inventory includes mainstream grades: DX51D+Z, DX53D+Z, DX56D+Z, SGCC, and SGH340, covering commercial-grade, deep-drawing-grade, and high-strength structural materials.

Zinc coating specification

In-stock options include various zinc coating standards: Z80 (80g/㎡), Z120 (120g/㎡), and Z275 (275g/㎡. We also accept US-standard orders for G60 and G90, meeting both domestic engineering and export requirements. Surface finishes available with spangle, small spangle, or zero spangle to suit applications requiring painting or direct exposure.

Product Advantages

Superior corrosion resistance: Continuous hot-dip galvanizing ensures strong zinc adhesion and sacrificial anode protection, effectively shielding the substrate from air and moisture. The Z275/G90 high-zinc coating is ideal for outdoor and coastal environments with high corrosion levels.

Stable forming performance

DX51D+Z / SGCC: General bending, simple forming; used for building envelopes, ducts, and shelving.

DX53D+Z, DX56D+Z: High-drawability deep-drawing material for appliance housings and automotive stamped parts.

SGH340: High-strength structural galvanized coil for steel structures and equipment load-bearing components.

Comprehensive Processing Support: Our warehouse is equipped with decoiling and slitting machines to provide custom cutting, film lamination, and packaging per customer requirements. We supply galvanized coils, cut-to-size sheets, and galvanized steel strips.

Factory Warranty: All steel shipments include mill test certificates and conform to specified dimensional tolerances. Third-party inspection is supported.
