(1) Before starting construction, check whether the color coated color coated sheet profiles meet the design requirements, whether the specifications are complete, and whether the colors are consistent
(2) The supporting framework (i.e. wall reinforcement) should be treated with anti-corrosion, fire-proof and anti-rust, especially the cut-edge and perforated part of the color-coated board should be treated with anti-rust to improve its durability and ensure the decorative effect.
(3) The position of the embedded parts and wall reinforcement should be consistent with the specifications and dimensions of the color-coated board and the heterogeneous board to reduce the secondary processing of materials on the construction site
(4) The surface of the wall after construction should be flat, with tight joints, reliable connection, and no warping, curling, etc.
1. Install the fixing parts, and fix the fixing parts on the purlins with self-tapping screws. Each purlin is provided.
2. Place a piece of color-coated board on the fixed fixing parts, and then compact it with the bottom groove of the center rib and inner rib of each fixing part, and make them fully engage.
3. Two 4m×3m scaffolds are erected with steel pipes, and each frame is equipped with 4 wheels for easy pushing.
4. Install the inner roof board first. According to the technical requirements, each wave crest is fixed with a 30mm long special self-tapping screw. The color of the screw cap is the same as the color of the color board.
5. Lay thermal insulation cotton, and seal the joints of thermal insulation cotton with special tape.
