SGCC Q345 G550 Galvanized Plain Sheet 0.5mm 900mm for Building Material
１．Product Overview
SGCC Q345 G550 galvanized plain sheet is used for building material, roofing, wall cladding, steel structure housing, warehouse panels, and general construction applications.
The galvanized surface provides corrosion protection, while the 0.5mm thickness, 900mm width, 5800mm length, and 180g/m² zinc coating support practical use in roofing and building envelope systems. Big spangle surface provides a typical galvanized appearance for construction projects.
２．Technical Solution
The product is manufactured from galvanized steel with zinc coating protection. The zinc layer helps reduce oxidation and rust during outdoor use, storage, and transportation.
Surface treatment options such as skin-passed, non skin-passed, and chromated finishes support different appearance, handling, and storage requirements. G550 grade provides higher sheet hardness for building material applications requiring better rigidity.
