1. What causes scratches or color differences on the surface of aluminum panels? How can they be avoided?

Causes: ① Inadequate protection during transportation/installation, resulting in collisions and friction between panels; ② Differences in coating processes (such as spraying temperature and paint mixing ratio) between different batches of products. Solutions/Preventions: ① Wrap the products with pearl cotton and bubble wrap during transportation, and handle them gently while wearing gloves during installation; ② Clearly specify the "same batch production" requirement to the manufacturer, and verify the batch number upon receipt.

2. The aluminum panel is labeled as "2.5mm thick", but the actual thickness is less than 2.5mm. Is this due to shoddy workmanship?

Not necessarily; it's important to distinguish between "substrate thickness" and "overall thickness": The industry-standard "thickness" usually refers to the substrate thickness (for the pure aluminum plate portion). The surface coating (such as fluorocarbon paint or polyester paint) thickness is approximately 0.02-0.05mm, which will result in the overall measurement value being slightly higher than the substrate thickness, but not lower.

3. What should be done if aluminum panels deform or bulge after installation?

Causes: ① Excessive keel spacing (e.g., using keel spacing >1.2m for large-sized panels), resulting in uneven stress on the panels; ② Inappropriate panel selection (e.g., using a substrate <2.0mm thick for large outdoor spans); ③ Overtightening screws during installation, compressing the panels. Solutions: ① Modify the keel structure, reducing the spacing as recommended by the manufacturer (e.g., for 2.5mm thick panels, keel spacing ≤1.0m); ② Replace with thicker substrate panels that meet the size requirements; ③ Readjust screw tightness to ensure the panels naturally conform to the keel.

4. What could be causing the aluminum panel exterior wall to leak during rainy weather? How can it be repaired?

Core causes: ① Aging or cracking of the sealant in the joints, or improper application (e.g., the sealant strip is not compacted, leaving gaps); ② Lack of waterproofing reinforcement at corners, window sills, and other joints. Repair methods: ① Remove the aged sealant and reapply weather-resistant silicone sealant (compliant with GB/T 14683 standard), ensuring the sealant joints are full and free of air bubbles; ② Apply waterproof membrane to corners, and slope the window sills outwards (slope ≥ 5°) to prevent water accumulation.

5. Will aluminum panels rust over time? How should they be cleaned and maintained?

Rusting: The aluminum composite panel substrate is made of aluminum alloy, which forms a dense oxide film on the surface, making it resistant to rust. However, if the coating is damaged (e.g., scratches exposing the substrate), prolonged exposure to rain may cause localized corrosion, requiring timely repainting. Daily Maintenance: ① Clean with a neutral detergent and a soft cloth (e.g., diluted dish soap). Avoid using strong acids/alkalis (e.g., toilet cleaner) or steel wool to prevent damage to the coating. ② Inspect outdoor panels every 1-2 years and repair any coating damage or aging sealant promptly.

6. How is the fire resistance of aluminum composite panels? Can they pass fire safety inspection?

The base material of aluminum single-panel panels (aluminum alloy) is a non-combustible material, and the surface coating (fluorocarbon paint, polyester paint) is mostly "fire-retardant B1 grade", which meets the fire protection requirements of most buildings (such as exterior walls and ceilings); Note: Some special locations (such as kitchens and electrical rooms) have higher fire protection requirements, requiring the customization of "fire-retardant coated aluminum single panels" from the manufacturer, and a fire protection test report must be provided.
