Common Problems and Solutions for Metal Curtain Wall Mesh
The following are some common problems with metal curtain wall mesh and their solutions:
1. Coating Peeling or Rusting: If bulges, discoloration, or a small piece of paint can be peeled off the surface of the metal curtain wall mesh, it may indicate aging of the anti-corrosion layer. In this case, first check the underlying metal for corrosion; otherwise, repainting will be ineffective. If loose screws are found, gently shaking the curtain wall panel will cause significant shaking or abnormal noise, indicating that the screws may be loose and need to be tightened.
2. Temperature Difference Deformation: Metal expands and contracts significantly with temperature changes, especially in seasons with large temperature differences. If the joints of the curtain wall suddenly widen or deform, it may be because insufficient expansion joints were left during installation. This situation requires adjustment by a professional team; attempting to pry it open yourself may worsen the problem.
3. Water Leakage: Leaks in metal curtain wall mesh can be caused by substandard aluminum profiles, improper sealant application, and broken or spontaneously shattered glass. Substandard surface treatment of the aluminum profiles, insufficient strength, or inappropriate sealant selection can all lead to leaks. Addressing these issues requires ensuring the aluminum frame is installed horizontally and vertically during construction, using weather-resistant sealant, and regularly maintaining the sealant strips.
4. Uneven Joints: Poorly sealed, uneven joints, air bubbles, and water seepage may be due to uneven pressure during caulking or poor sealant quality. Solutions include selecting high-quality sealant, ensuring skilled caulking techniques, maintaining even pressure, and promptly addressing air bubbles and water seepage.
5. Surface Contamination and Unevenness: Surface contamination and unevenness may be due to premature removal of the protective film or improper protection of the product during subsequent construction processes. Solutions include avoiding premature removal of the protective film, developing feasible product protection measures, and promptly cleaning up contaminated areas.
