750–1250mm Zinc Coated Hot Dipped Galvanized Steel Coil with Spangle Surface for Construction and Industrial Fabrication
1. Product Overview
Hot dipped galvanized steel coil is produced by coating carbon steel with zinc through a continuous galvanizing process. The zinc layer improves corrosion resistance and helps extend service life in environments where the steel is exposed to moisture, air, and routine industrial use.
This product is offered in widths from 750 mm to 1250 mm, making it suitable for roofing panels, structural accessories, appliance parts, and general sheet fabrication. Surface condition can be selected as regular spangle, zero spangle, or mini spangle according to appearance and downstream processing requirements.
2. Technical Solution
Product performance is based on the following technical characteristics:
- Continuous hot dip galvanizing for stable coating adhesion
- Zinc layer providing barrier protection and sacrificial protection
- Width range suitable for panel forming, slitting, and sheet processing
- Selectable spangle condition for different visual and processing requirements
A zinc coating range of 60–275 g/m² is commonly used for construction and industrial applications. Lower coating levels are usually applied in controlled indoor environments, while higher coating levels are preferred where stronger corrosion resistance is required.

- Outdoor or humid environment → higher coating such as 180–275 g/m² is commonly used
- Roofing or structural profiles → select thickness according to stiffness and forming requirements
8. FAQ
Q1: What is the difference between regular spangle, zero spangle, and mini spangle?
Regular spangle gives a traditional galvanized appearance, zero spangle is preferred for painting or cleaner surface requirements, and mini spangle provides a more controlled visible finish.
Q2: Is 750 mm width suitable for construction applications?
Yes, 750 mm width is commonly used for roll formed roofing panels and other construction sheet products.
Q3: What zinc coating is commonly used for outdoor use?
For outdoor construction and exposed applications, higher coating levels such as 180–275 g/m² are typically selected for better corrosion resistance.
Q4: Can the coil be supplied as sheets or strips?
Yes, the material can be processed into cut-to-length sheets or slit strips according to downstream fabrication requirements.
Q5: Is this product suitable for appliance and industrial fabrication?
Yes, it is widely used for household appliance panels, industrial cabinets, refrigeration equipment, and general sheet metal fabrication.
