0.14~1.2mm Color Coated PPGI Prepainted Galvanized Steel Coil/Sheet For Corrugated Roofing Sheet JIS G3302/ASTM A653
Brief Introduction
1. PPGI Prepainted Galvanized Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvalume steel sheets.
2. The base metals for PPGI Prepainted Galvanized Steel Coil consist of cold rolled steel, HDGI steel, electro-galvanized steel and hot-dip alu-zinc coated steel. The finish coats of PPGI Prepainted Galvanized 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.
4. The color of the PPGI Prepainted Galvanized Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.
5. The PPGI Prepainted Galvanized Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.
