colored galvanized sheet metal

The metal gray roofing system is applied to roofs of various shapes. The length of the panels is not limited, the angle is adjustable, it can be naturally bent forward and backward, and the shape is beautiful;

There are no exposed fixing screws, no need to penetrate the roof, and structural waterproofing is adopted;

The roof system and the main structure are reliably connected and can directly form a lightning protection system;

Reliable three-phase temperature difference deformation performance will not cause shear damage to the fixed parts;

The whole system is corrosion-resistant, maintenance-free, and has excellent durability; when used in conjunction with thermal insulation cotton, sound-absorbing cotton, and surface decorative panels, it can obtain superior heat insulation and sound insulation performance; the fire protection performance level reaches Class A, and lighting skylights can be installed on the roof at will. , can open fire smoke exhaust windows and BMU tracks.

The fixing method adopts hidden buckles and mechanical locking, and no screws pass through the roof, thus avoiding the risk of water leakage.

Fully machine-fitted, seamless hemming, no chemical caulking glue required to avoid the risk of water leakage due to aging.

The overall structural waterproofing and drainage performance is outstanding, maximizing the use of panel cross-sectional area for drainage and high drainage efficiency.
