Performance Characteristics
1. Tensile & Bend Strength
Our modified bitumen roof cap sheet achieves tensile strengths of 260–620 MPa through cold-rolling and annealing processes, ensuring resistance to wind uplift (up to 180 mph) and structural deformation. Bend strength is tested at 180° without cracking, even in sub-zero conditions (-40°C), making it ideal for regions with heavy snowfall.
2. Weight Calculation
- Formula: Weight (kg/m²) = Thickness (mm) × 7.85 (steel density).
- Example: A 0.5 mm sheet weighs 3.925 kg/m², 50% lighter than asphalt shingles.
3. Corrosion Resistance Mechanism
The tin/chromium layer acts as a sacrificial anode, where tin oxidizes preferentially to protect the steel substrate. In coastal or acidic environments, the outer tin layer resists pitting, while the chromium oxide inner layer blocks rust diffusion.
4. Why Stainless Steel Can Rust?
- Electrochemical Corrosion: Foreign particles (e.g., iron dust) create micro-cells with moisture, accelerating oxidation.
- Organic Acids: Food residues or pollutants form corrosive organic acids over time.
- Chemical Exposure: Direct contact with salts, alkalis, or industrial pollutants degrades protective layers.
Key Features
- Weatherproof Design: Withstands temperatures from -40°C to +120°C and UV radiation for 50+ years.
- Easy Installation: Pre-punched holes and interlocking edges reduce labor costs by 30%.
- Low Maintenance: Self-cleaning surface prevents algae and dirt accumulation.
- Eco-Friendly: 100% recyclable with GalvaTec™ coating.
Applications
- Industrial: Chemical plants, coastal infrastructure.
- Commercial: Warehouses, airports, solar panel mounting systems.
- Residential: Eco-friendly homes, garages.
