35mm Width Zero Spangle Hot Dipped Galvanized Steel Coil HDG for Building

35mm Width Zero Spangle Hot Dipped Galvanized Steel Coil HDG for Building Materials and Industrial Freezers

１．Product Overview

35mm width hot dipped galvanized steel coil is used for building materials, roofing sheets, outer wall panels, ovens, industrial freezers, furniture components, construction parts, automotive applications, metallurgy, and electrical appliance manufacturing.

The product is manufactured by hot dipped galvanizing, with zinc coating from 60g/m² to 275g/m². Zero spangle surface is suitable for applications requiring a smoother galvanized appearance, while regular, minimized, and big spangle options are also available for different project requirements.

２．Technical Solution

The steel substrate is coated on both sides through a hot dipped galvanizing process to improve corrosion resistance and surface protection.

Surface treatments include passivated, chromated, oiled, and anti-finger treatment. These options support storage protection, shipment stability, and downstream processing.

Base metals can include SPCC, SPCD, SPCE, DX51D, DX53D, Q195, and Q235. Cutting and slitting can be arranged according to customer requirements.

３．Specifications

４．Application

This galvanized steel coil is suitable for roofs, outer walls, ovens, industrial freezers, residential buildings, industrial buildings, construction components, automobile parts, metallurgy applications, electrical appliances, furniture parts, and general steel fabrication.

It can also be used for applications requiring narrow-width galvanized strip after slitting.

５．Processing

The product supports slitting, cutting, decoiling, roll forming, bending, stamping, punching, profiling, and fabrication.

Customized width, thickness, zinc coating, spangle type, surface treatment, and packing method can be supplied according to customer requirements.

６．Advantages

• 35–1250mm width range supports narrow strip and standard coil applications.
• 60–275g/m² zinc coating supports corrosion resistance for building and industrial use.
• Zero spangle provides a smoother surface for applications requiring better appearance or further coating.
• Passivated, oiled, and anti-finger treatments improve storage and handling performance.
• SGCC, DX51D, SGCH, and related grades support different forming and fabrication needs.
• Export standard packing supports long-distance sea transportation.

７．How to Choose

• Choose zero spangle when smoother surface appearance is required.
• Choose regular spangle when traditional galvanized appearance is acceptable.
• Choose SGCC or DX51D for general building material and forming applications.
• Choose SGCH when higher hardness is required.
• Choose higher zinc coating for outdoor, humid, or corrosion-sensitive environments.
• Confirm thickness, width, zinc coating, grade, spangle, surface treatment, and packing method before production.
