What are the precautions for installing polyurethane sandwich panels?

Precautions for installing polyurethane sandwich panels

1. When cutting the workshop sandwich panel, pay attention to the exposed surface facing down to prevent the scraps from sticking to the coating surface during cutting, which will cause the gasification of the scraps.

2. The builder should pay attention when walking on the roof construction. When walking along the drainage direction, they should step on the board valley, when walking along the purlin direction, they should step on the purlin, and they must wear soft-soled flat shoes.

3. When the roof of the color steel sandwich panel factory is to be longitudinally lapped, the length should be more than 15cm, and the lapped position should be at the purlin position.

4. When fixing the color steel sandwich panel on the rib with self-tapping screws, pay attention that the recessed part should be about 1.5mm from the center line of the self-tapping screw. If it is too tight, you need to add water-stop glue to do the waterproof work. If it is too loose, you must do the locking work again.

5. Before finishing the work, the polyurethane sandwich panels on the frame of the factory and on the ground should be tied with nylon ropes to prevent accidents.
