Granite Prepainted Galvalume Steel Coil
Details
Using cold-rolled steel plate as the substrate, a layer of aluminum zinc coating composed of 55% aluminum, 43.5% zinc, and 1.5% silicon is hot dipped on its surface, and then coated with one or more high-quality coatings. The paint comes in a variety of colors, including metallic and solid colors, with a surface texture similar to granite, presenting a unique aesthetic effect.

Description

Features

 

1.Ultra-thin and lightweight: The thickness is only 0.1mm level, the weight is only 1/20 of the traditional steel plate, easy to carry and construct

2. High flexibility: Can be bent 180 degrees without cracking, can be adapted to irregular surface decoration

3. Excellent electromagnetic shielding: The aluminum-zinc-titanium coating has excellent electromagnetic shielding performance, can meet the electromagnetic protection requirements of electronic equipment

4. Fast curing and delivery: UV one-time curing process, the production cycle is only 1/3 of the traditional process, can achieve rapid delivery

5. Customizable pattern: Support small batch custom pattern, can quickly adjust the granite texture according to customer needs
