Key Points of Construction and Installation Technology for Pre-coated Color Galvanized Steel Sheets
Time：2025-08-30
The quality of construction and installation directly affects the performance of pre-coated color galvanized steel sheets, requiring control over four key aspects:
Sheet Storage: Avoid contact with corrosive substances. Store in a dry, well-ventilated area using horizontal stacking to prevent deformation or coating scratches.
Cutting Process: Plasma cutting or specialized cutting tools are recommended. Avoid flame cutting which damages the galvanized layer and coating. Burrs on cut edges must be promptly removed to prevent rusting.
Installation: Select appropriate fixing methods based on sheet type. Profiled sheets commonly use self-tapping screws for fixation. Sandwich panels require tight 拼接 with proper sealing at joints to prevent water leakage.
Surface Protection: Sharp tools should be kept away from sheet surfaces during construction. After installation, promptly clean surface dust and stains to ensure a neat appearance. Inspect for coating damage and repair scratches immediately if found.
