ASTM A755/A755M is a standard specification established by the American Society for Testing and Materials (ASTM International). We specialize in supplying ASTM A755 pre-painted steel coils, which are color-coated steel sheets that comply with international standards.
The product uses hot-dip galvanized steel or galvanized-aluminum steel as the base material and is produced using a coil-coating process. It offers excellent corrosion resistance, formability, and decorative appeal, making it suitable for a wide range of applications.

ASTM A755 Color-Coated Steel Coils
Pre-painted steel coils are currently in production.
| Substrate Type | Corresponding ASTM standards | Features |
| Hot-dip galvanized steel (GI) | ASTM A653/A653M | Using pure zinc as the coating, it has excellent electrochemical protective properties. |
| Aluminum-zinc alloy coated steel (GL/AZ) | ASTM A792/A792M | The 55% aluminum/43.4% zinc/1.6% silicon alloy coating provides 2-5 times the corrosion resistance of hot-dip galvanized steel and excellent heat resistance. |
ASTM A755 pre-painted steel coils, with their excellent corrosion resistance, formability, and decorative properties, are commonly used in the following industries:
They can be used for roofs, walls, curtain walls, balcony panels, and door and window frames in industrial plants, commercial complexes, warehouses, prefabricated houses, and portable buildings; they can also be processed into corrugated sheets and sandwich panels for thermal insulation walls in cold storage warehouses and cleanrooms.
Suitable for the production of outer casings, side panels, and back panels for home appliances such as refrigerators, washing machines, air conditioners, and water heaters. Colors and surface textures can be customized to meet specific brand requirements; we offer a wide range of colors and finishes for home appliance-grade color coated steel.
Can be used for automotive body panels, shipping container side panels, etc.; Modular buildings, mobile homes, guard booths, billboards, traffic facilities, and agricultural machinery housings, as well as decorative materials for interior ceilings, partitions, and furniture panels.
Construction Use
Home Appliance Uses
Q1: Can the specifications, colors, and textures of ASTM A755 pre-painted steel coils be customized?
A: Yes, customization is available. For coil customization, we have slitting and shearing equipment to adjust width and length. Colors are based on the RAL color chart; if you have a specific color sample, please mail it to us. Surface finishes can be customized to include matte, glossy, textured, wood grain, and more.
Q2: What is the difference between ASTM A755 pre-painted steel coils and standard pre-painted steel sheets?
A: ASTM A755 is a standard specifically designed for architectural applications exposed to outdoor environments. It imposes strict technical requirements on the substrate coating, organic coating system, coating adhesion, and weather resistance. This standard explicitly stipulates that pre-painted steel coils must use hot-dip galvanized steel sheets as the substrate and apply the organic coating continuously via a coil-coating process.
Q3: What are the minimum order quantity, delivery time, and payment terms for ASTM A755 pre-painted steel coils?
A: Our minimum order quantity is 10 tons; we recommend purchasing approximately 25 tons (one container), as this is more cost-effective in terms of shipping and pricing—the larger the quantity, the more favorable the price. Delivery time is determined by the quantity and typically ranges from 7 to 30 days. Currently, we only accept payment via TT.
