How to ensure the quality of color steel plate

Color steel plate is suitable for industrial and civil buildings, warehouses, special buildings, roofs, walls, and interior and exterior wall decoration of large-span steel structure houses, etc. It has the advantages of light weight, high strength, rich colors, convenient and fast construction, earthquake resistance, fire resistance, rain resistance, long life, and maintenance-free. It has been widely promoted and applied. So, how to guarantee the quality of color steel plate?

1. Workers should receive protection education first, pay attention to the main points of construction operation every day before the shift, and strengthen quality awareness education. Before the construction of each process, detailed skills should be clarified to the workers.

2. All materials and equipment required for the project need to have a certificate of conformity or material certificate, and all kinds of certificates must be registered and checked with the actual object. Without this document, inspection or construction may be rejected. If in doubt, check and judge it, and use it only after passing the check.

3. The color steel plate device should be flat and straight, and there should be no construction residue and dirt on the surface of the plate. The cornice should be in a straight line and there should be no untreated wrong drilling.

4. Transportation, stacking and hoisting are forbidden to deform the color panels and paint peeling off.

5. The top of the gable flooding layer is 250mm high, and the slope along the roof is 10mm and 15mm high. Secondly, use M6 expansion bolts to fix the connection between the waterproof plate and the groove, and seal the exposed expansion bolts with sealant; the joint with the roof plate is fixed on the roof plate bracket with self-tapping screws, and the connection between the waterproof plate and the roof plate The joint is waterproof with a long water-retaining belt.

6. After the color steel plate is formed, there should be no visible cracks, peeling and scratches on the coating and plating.

7. The color steel plate, flashing plate and corner plate should be fixed firmly, and the anti-corrosion coating and sealing materials should be well laid.

8. After the color steel plate is formed, the appearance should be clean, and there should be no obvious bumps and wrinkles.

9. The project manager department and other operating forces should strictly follow the approved technical documents for construction, and should not be changed at will. On-site technicians and quality inspection staff have the right to inspect the performance status and promptly correct the construction methods that violate the established methods.

10. If defects in the original construction process of the color steel plate are found, the on-site technical person in charge proposes a modification opinion, and after the original approval part is approved, the change will be notified in the form of a skill contact sheet.

11. The construction personnel can put forward reasonable suggestions on the approved skills and methods, and after the approval of the original approved part, use the contact list to inform the change.
