740mm Hot Dipped Galvanized Steel Sheet Zinc Coated Coils

1. Product Overview

Hot dipped galvanized steel coil is used where the steel substrate needs zinc protection before forming, cutting, or installation. This product range is suitable for industrial panels, building components, steel structure parts, and general sheet metal fabrication where coating mass, thickness, width, and surface condition need to be selected together.

The listed technical range covers 0.13-5.0mm thickness and 100-1250mm width. That means the product can be supplied both as standard-width coil and as slit coil for narrower processing routes. A project width such as 740mm falls within the listed slit-width capability.

2. Technical Solution

This product uses a hot dip galvanized coating route. In practical use, corrosion performance depends mainly on zinc coating mass, cut-edge exposure, drainage condition, storage method, and the final operating environment.

The listed zinc coating range is 30-275g/m2. Lower coating levels are generally used for lighter or controlled service conditions, while higher coating levels are more suitable for more demanding environments. The product also offers multiple surface conditions including chromed, skin pass, oiled, slightly oiled, and dry, which affect handling, storage stability, and downstream forming behavior.

Spangle options include zero spangle, minimized spangle, regular spangle, and big spangle. Spangle selection mainly affects surface appearance and downstream finishing consistency rather than base load-bearing capacity.

4. Application

This material is suitable for industrial panels, building sheets, steel structure parts, roofing components, outer wall components, garage doors, and general fabricated galvanized parts.

It can also be used in household appliance housings, transportation-related parts, industrial control cabinets, refrigeration equipment housings, vending machine panels, and furniture-related sheet fabrication where zinc-coated steel is required before final assembly.

5. Processing

• The coil can be processed by slitting, cut-to-length, bending, profiling, punching, and general sheet metal fabrication.
• For narrow-width applications, slit widths within the listed 100-1250mm range can be supplied according to project requirements. If the final product is a narrow strip or formed channel, the width should be selected according to blank layout, bend allowance, and final profile geometry.
• For visible parts, spangle type and surface condition should be confirmed before production because they affect final appearance and handling behavior.

6. Advantages

• The 0.13-5.0mm range covers both light gauge processing and heavier fabricated sheet applications.
• The 100-1250mm width range supports both standard-width coil supply and slit coil processing for narrower parts.
• The 30-275g/m2 zinc coating range allows the material to be selected according to actual corrosion requirement instead of using one fixed coating level for all projects.
• Multiple spangle and surface treatment options make the product easier to match to visible-surface requirements, storage route, and downstream fabrication.
• 508mm and 610mm coil IDs fit common decoiling and slitting equipment.

7. How to Choose

• Choose zinc coating level according to the service environment. For protected indoor or lighter conditions, lower coating levels may be acceptable. For more demanding use, a higher coating level within the listed range is generally more suitable.
• Choose thickness according to rigidity and forming route. Thin gauges are more suitable for lighter formed parts, while thicker gauges are more suitable for stronger fabricated components and higher stiffness requirements.
• Choose width according to the final blank size and forming layout. If the project needs narrow strip or custom width such as 740mm, confirm slit width and coil handling route before ordering.
• Choose zero or minimized spangle when surface uniformity is more important. Choose regular or big spangle when conventional galvanized appearance is acceptable.

8. FAQ
