BiLAP™ is a Over Lap Type Rock Wool Corrugated Roof Sandwich Panels, the special design of the ends is able to effectively prevent water seepage and ensure waterproof. With outstanding expansion and contraction performance, allow room to relieve stress, with fast installation and efficient construction guaranteed. The hidden screws guarantee excellent waterproof performance and prevent screw corrosion and thermal bridge phenomena. 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 purlins, improved the bearing capacity and balanced the running water action. Without lapping design, the edge is corroded for the lack of coating after being soaked by rain water,which shortens the service life of roofing. The lapping design features a closer lapping effect, protects the edges without coating and improves the service life of roofing.
