Zero Spangle Galvanized Steel Coils – Core Product Range

Luxu Supply Chain offers a comprehensive range of zero spangle galvanized steel coils engineered for the most demanding applications in home appliance manufacturing, construction, and pre-painted substrate production. As a professional galvanized steel coil supplier based in Shandong, China – the nation‘s largest metal sheet production hub – we deliver consistent quality backed by advanced continuous hot-dip galvanizing lines and rigorous quality control standards.

Our product portfolio centers on hot-dipped galvanized steel coils manufactured to meet international specifications including DX51D+Z, SGCC, and ASTM A653. Every GI steel coil we produce combines superior corrosion resistance, excellent formability, and a flawless surface finish – attributes that make our materials the preferred choice for manufacturers of refrigerators, washing machines, air conditioners, and premium building materials.

GI Steel Coil Specifications

We produce galvanized steel coils across a flexible range of dimensions and coatings to suit diverse application requirements:

• Thickness: 0.2mm to 0.8mm (thin-gauge coil specialization)

• Width: 700mm to 1250mm

• Zinc Coating Weight: 30 to 180g/m² (Z30 to Z180)

• Material Grades: DX51D+Z, DX52D+Z, SGCC, and equivalents

• Spangle Type: Zero spangle (standard), minimized spangle available

• Coil ID: 508mm or 610mm

• Coil Weight: 3-10 tons per coil

Surface Treatment Options

The surface quality of a zero spangle galvanized steel coil is critical to its performance in visible applications. We offer multiple treatment layers to meet specific manufacturing and environmental requirements:

• Anti-Fingerprint Coating – An organic resin layer that prevents stains and fingerprints during appliance assembly, maintaining aesthetic integrity throughout production. This is particularly valuable for home appliance galvanized steel coil applications such as refrigerator back panels and outer casings.

• Chromate-Free Passivation – An environmentally friendly chemical treatment that provides corrosion resistance without hexavalent chromium. This chromate free galvanized steel coil option complies with global environmental regulations including RoHS and REACH.

• Oiled / Unoiled – Optional light oil application for additional corrosion protection during storage and transport.

• Skin-Passed / Tempered – Improved surface flatness and uniform appearance through precision rolling.

Applications for Our Galvanized Coil Products

Our hot dipped galvanized steel coils serve multiple industries with tailored solutions:

• Home Appliance Manufacturing – Refrigerator back panels, washing machine housings, air conditioner components, and microwave oven shells. The zero spangle surface ensures excellent paint adhesion and a premium finish for visible parts.

• Pre-Painted Substrate (PPGI) – Our GI steel coil serves as the ideal base material for color-coated steel production. The spangle-free surface provides superior paint adhesion and a smooth foundation for decorative finishes.

• Building & Construction – Roofing panels, wall cladding, and structural components. Building grade galvanized steel from Luxu meets the durability requirements of both residential and commercial construction projects.
