About installation: 1. When installing ,ensure that the ribs sheet face downwards.This can reduce the accumulation of internal dust and facilitate the discharge of condensate.There must be a min installation gradient of 5%, and eht rib direction is
consistent with the slope keel
2. The arc installation of the plate does not require heat treatment, and can be cold-formed first. The bending radius should be greater than the minimum allowable range, which is more than 175 times the plate thickness. Bending in the direction of the ribs, the wrong bending direction will cause inappropriate changes, which will lead to premature damage to the warranty.
3. The distance between the curved arc pipes is 1050mm. If the distance is too large, it will affect the snow and wind resistance of the plate and cause the plate to break.
4.The design and installation of the board must consider its coefficient of thermal expansion (0.065mm/m°C). When drilling and installation are required, the distance between the renting control center and the edge of the board should be at least 30mm. The drill hole diameter should be 1.5 times the screw diameter. When the design installation length exceeds 6000mm, the expansion margin should be increased, and the neutral structural glue can be used to seal if necessary.
5. For solid plates, expansion holes must be reserved, and the minimum expansion hole should be greater than 1.5 times the diameter of the drill tail wire
6.Contact with any acidic or alkaline substances on the board will cause premature aging of the board. It is forbidden to use PVC doctrines and gaskets. Its decomposition products will damage the board.
7. Before installation, avoid direct exposure to sunlight for a long time
8.Do not remove the protective film in advance before completing the project. It will electrostatically attract dust and scratch the surface. It should be removed one week after completion. Use a diluted neutral detergent to clean the surface of the board, then rinse with water and wipe with a soft cloth.
