• Structural Stability: Lightweight yet strong to withstand wind and snow loads.

• Corrosion Resistance: Top layer and coatings protect from rain, pollution, and UV.

• Fire Safety: Insulation cores prevent flame propagation.

4. Installation Instructions

Correct installation ensures maximum performance, safety, and energy efficiency.

4.1 Preparation

• Verify roof frame is level, stable, and capable of supporting sheet weight.

• Ensure minimum slope of 3–5° for efficient water drainage.

• Inspect sheets for any defects or damage prior to installation.

• Gather required tools: electric drill, measuring tape, level, stainless steel screws with rubber washers, sealant, gloves, and safety harness.

4.2 Installation Steps

1. Begin from the bottom edge of the roof and work upward.

2. Align sheets properly to ensure interlocking and water-tight overlaps.

3. Fix sheets with stainless steel screws and rubber washers to prevent leakage.

4. Apply sealant at joints and overlaps to enhance waterproofing.

5. Avoid walking directly on installed sheets; use protective planks.

6. Inspect completed installation for alignment, fastening, and surface integrity.

4.3 Safety Considerations During Installation

• Always wear helmets, gloves, and anti-slip shoes.

• Use safety harnesses on sloped roofs.

• Avoid installation during extreme weather conditions.

• Handle sheets carefully to prevent dents, scratches, and coating damage.

5. Maintenance and Repair Procedures

Routine maintenance and timely repairs ensure long-lasting performance.

5.1 Recommended Maintenance Schedule

5.2 Cleaning Guidelines

• Use low-pressure water and mild detergent.

• Avoid abrasive brushes or harsh chemicals.

• Coastal or industrial areas may require more frequent cleaning.

5.3 Repair Guidelines

• Water Leakage: Check for loose screws or gaps; tighten and reseal overlaps.

• Surface Damage: Small scratches can be treated with UV-resistant touch-up paint.

• Dents or Deformation: Replace affected sheets; avoid walking directly on roof.

• Corrosion Spots: Apply protective coating to exposed areas immediately.

6. Troubleshooting Common Issues

7. Solutions for Enhanced Performance

To maximize energy efficiency and durability:

• Ensure proper ventilation under the roofing system to prevent condensation.

• Install reflective coatings for areas with high solar exposure.

• Use high-quality sealants at overlaps and joints to prevent water ingress.

• Reinforce fasteners in high-wind areas.

• Schedule routine inspections to detect issues early and reduce maintenance costs.
