Color Galvanized Steel Corrugated Roof Panel RP2

Fireproof Galvanized Steel Corrugated Roof Panel Corrugated Steel Roofing Sheets

Corrugated steel sheet (Roofing sheet) is a building material composed of sheets of hot-dip galvanized mild steelor Galvalume steel,cold-rolled to produce a linear corrugated pattern in them. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them. Normally each sheet is manufactured longer in its strong direction.Material: SGCC, SGCH, G550, DX51D, DX52D, DX53D

Pre-painted Galvanized steel is a Galvanized steel with a number of paint layers and treatments in a carefully controlled environment in a continuous coil coating line.
Pre-painting can also be done on electrogalvanized coils and cold rolled coils depending on the end-use and application of the steel.

PPGI Steel Coil is better at corrosion resistance. Paint on hot dip galvanized steel make it decaorative and usually used to indoor and outdoor decoration. Service life of PPGI coils can up to 20 years without fading.(Zn 60g, 25um painted in top and 10um painted in back). Production meets the standard of EN10147 DX51D+Z, JIS G3312 CGCC, ASTM A755M A653M.
