Color Coated Steel Coil UV Resistant Pre Painted Coils Anti Impact
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.
