The following manufacturers ofpre painted steel sheet will introduce the following points to pay special attention to during the installation ofpre painted steel sheet:
(1) The top of the purlin used for support must be on the same plane. The position of the purlin can be adjusted according to the actual need to tap or relax. Do not directly adjust the slope and position of the roof under the fixed bracket for verbal attack. Correctly configuring the color-coated sheet can ensure effective bending. Conversely, if the pre painted steel sheet are not properly aligned when placed, the warpage of the color-coated plates will be affected, especially near the center of the support.
(2) In order to prevent the prepainted steel sheet from becoming fan-shaped, collapsing, and inconsistent with the lower edge of the roof due to construction errors, always check whether the color coating plate is correct when installing on the color coating plate, and measure the color coating plate at any time Are the distances from the upper and lower ends of the ceiling to the gutter equal to avoid tilting the color coating plate.
(3) Remove metal fragments such as sprinkler fragments, rivet rods, fasteners, etc. remaining on the roof after installation. These metal fragments will cause corrosion of the prepainted steel sheet.
