Residential Precast Unit PPGL Coil Sheet Zinc Coating 30g - 275g AISI JIS

 

 

Specification:

1. Weight of Steel Coil: 4-10MT

2. Available Dipped AZ Coating : 50-150g/m2

3. Surface Texture: Normal Coated

4. Type of coating structure: 2/1 Coat the top surface of the steel sheet twice, 

    coat the bottom surface once, and bake the sheet twice.

5. Front side paint thickness: 15-25μm (bottom paint + top paint)

6. Back side paint thickness: 5-7μm

 

Brief Introduction:

1. Prepainted Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

2. The base metals for Prepainted Steel Coil consist of cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of Prepainted Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.
