Experience the exceptional strength and longevity of Galvalume Steel Coils, the choice for your industrial and architectural projects.
Galvalume steel coil is a type of steel sheet that has been coated with an alloy of aluminum and zinc. The coating typically consists of about 55% aluminum, 43.4% zinc, and 1.6% silicon.
This combination provides the steel with enhanced corrosion resistance, heat reflectivity, and durability compared to traditional galvanized steel.

| Thickness | 20 - 32 Gauge (0.3-1.0 mm) |
| Width | 23'' - 48'‘ (600 -1250 mm) |
| Coil ID | 508/610mm |
| Coil weight | 3-8 tons |
| Steel Grade | Commercial Steel,Forming Steel and Structural Steel |

Acrylic Coated Galvalume with a layer of Acrylic applied to it to prevent fingerprints during handling, manufacturing, and installation. It cannot be painted and can only be used bare.
It can be dry roll-formed without lubrication and can roll-form pre-painted steel on the same roll-forming machine without extensive cleaning of the roll-forming dies.
We mainly sell AZ50, AZ55, and AZ150 galvalume steel coils. AZ50 and AZ55 are ASTM A792 standard coating designations, meaning weights of 0.50 ounces/square foot and 0.55 ounces/square foot. AZ150 is a coating designation according to EN 10346 standard, which means the weight is 150g per square meter.
AZ50 is equivalent to AZ150;
AZ55 is equivalent to AZ165;
In addition we can also produce galvalume with lower coating weight, please contact sales.
We have the ability to supply AZ165 galvalume to meet customers’ requirements for use in highly corrosive areas. We ensure that the weight of the metallic coating does not cut corners, and we have the equipment to detect it.
Innovative Coating Technology
Galvalume Steel Coils feature a unique coating of aluminum-zinc alloy, combining the best properties of both metals. This innovative coating not only enhances the coil’s durability but also provides superior heat reflectivity, making it an ideal solution for energy-efficient buildings.
AI-Zn coating: AZ150 gsm(min), Thickness: 0.40 mm(min), Grade: ASTM A792 CS type
COSASTEEL strictly follows the standards of EN 10346, ASTM A792M, JIS G 3321, and AS1397 to produce galvalume steel coils. When ordering, please confirm the standard steel grade and Weight[Mass] of Coating with the supplier.

Check tariffs before ordering from China.
Galvalume steel coil has good corrosion resistance. It can balance the protective and repair effects of zinc with the anti-corrosion effect of aluminum, extending the service life of steel sheets.
Galvalume steel coil has relatively good heat resistance and will not change color when exposed to temperatures of around 316 degrees for a long time. It still has good antioxidant properties at a temperature of 677 degrees.
The price of galvalume steel coil is affected by the price of raw material hot-rolled coils and the thickness, width, and AI-Zn coating weight.
