China Prepaint Galvalume Steel Coils Prepainted Aluzinc Steel Sheet

1. Prepaint Galvalume Steel Coil brief introduction
1) Prepaint Galvalume Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel coils.
2) base metals for Prepaint Galvalume Steel Coil is hot-dip galvalume steel. The finish coats of Prepaint Galvalume Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.
3) 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 Prepaint Galvalume 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) Prepaint Galvalume Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.
2. Prepaint Galvalume Steel Coil main usage:
Prepaint Galvalume Steel Coil is often used as building materials(ceiling, metal roof tile) machinery parts(electrically controlled cabinets, road maintain board, etc, so prepaint steel coil is mainly used in advertising industry, construction, household appliances, industry, electrical industry, furniture industry and transportation.
3. Prepaint Galvalume Steel Coil quality control:
Strict procurement process---skillful technical workers---final products inspection(resistance to corrosion, salt spray test, exposure test, machinability, thermal resistance)---standard packing
