PLATE ADVANTAGES
The concave edge of the lap joint adopts the lapping technique so the lapping is tighter, avoids rusty edges caused by no coating, extends the service life of panels and increases the strength. On the other hand, it prevents constructors from damage. The crest wave height is 34 mm. The three-crest wave design has improved the bearing capacity of roof panels, reduced the amount of roof purlines, improved the bearing capacity and balanced the running water action. The design of water tanks ter leakage.
PLATE UPGRADE
Roof panel wave structure upgrade, can fix clamp directly, that makes installation of roofing photovoltaic solar and other systems easy and safe, promote effective utilization rate of roof.
