Common specifications of galvanized coils mainly include parameters such as thickness, width, length, and zinc layer weight. Different applications have different specification requirements. The following is a detailed explanation based on mainstream standards and market supply:
Thickness Specifications
The thickness of galvanized coils typically ranges from 0.2mm to 4.0mm. Common thicknesses are as follows:
- Thin (0.2–0.6mm): Suitable for applications where weight is a concern, such as appliance casings, ventilation ducts, and interior decoration.
- Medium Thickness (0.8–1.5mm): Widely used in building roof panels, automotive structural components, and furniture frames.
- Thick Plate (1.8–4.0mm): Primarily used in heavy industrial equipment, bridge components, and large storage tanks where high strength support is required.
Width Specifications
- Width is one of the important dimensions of galvanized coils. Common standard widths include: 1000mm; 1219mm / 1250mm (most commonly used); 1500mm
- Special widths can reach 1524mm or 1829mm, suitable for large-scale construction or custom processing.
- Some manufacturers support slitting, which can cut wide coils into narrower steel strips, such as 100mm wide galvanized steel strips for small parts manufacturing.
Length Specifications Galvanized coils are supplied in "coils," and the length is not fixed, depending on the coil weight and the total length after unfolding:
- C coil (standard coil): Unfolded length approximately 2000–6000 meters
- L coil (long coil): Up to 8000–12000 meters, suitable for continuous production lines, reducing joints
They can also be cut into standard lengths according to customer requirements, common sizes such as 1m×2m, 1.25m×2.5m, 1.5m×3m, etc.
