Impact-Resistant Tin Roofing Sheets | Storm-Ready Design

Product Overview
Our corrugated iron roof sheets are engineered to withstand extreme weather conditions, combining military-grade durability with architectural versatility. Designed for residential, commercial, and industrial applications, these sheets meet ASTM A792 and EN 10346 standards, ensuring resistance to hurricanes, hail, and seismic activity. Available in galvanized, stone-coated, and pre-painted variants, they redefine roofing safety while offering discount sheet metal roofing affordability. Compatible with home depot sheet metal roofing systems, they integrate seamlessly into modern and traditional structures.

Technical Specifications

Certified to ISO 9001, Miami-Dade HVHZ, and UL 580 wind uplift standards.

Performance Attributes

Tensile Strength

Our corrugated iron roof sheets achieve tensile strengths of 380–700 MPa (DX51D) and 550–620 MPa (SGCC), outperforming traditional asphalt shingles by 300%. The dual-phase microstructure balances ductility and rigidity, resisting wind loads exceeding 175 mph (UL 580 certified). For high-risk seismic zones, the sheets’ yield strength of 350–550 MPa ensures structural integrity during ground movements.

Bendability

Precision roll-forming technology enables bending radii as low as 1.2× thickness without cracking, critical for complex installations like arched roofs. Cold-rolled edges minimize material waste during home depot sheet metal roofing retrofits, while pre-drilled holes ensure compatibility with standard stainless steel fasteners.

Weight Calculation

• Galvanized Steel: 7.85 g/cm³ (e.g., 0.5 mm sheet = 3.93 kg/m²)
• Aluzinc (55% Al-Zn): 7.2 g/cm³ (e.g., 0.6 mm sheet = 4.32 kg/m²)
  Lightweight designs reduce structural support costs by 25–40% compared to concrete tiles, ideal for retrofitting older buildings.

Anti-Corrosion Mechanism

Stainless steel’s chromium oxide layer (≥10.5% Cr) provides passive protection against oxidation, while Galvalume coatings (55% Al, 43.4% Zn, 1.6% Si) offer 4× longer lifespan than standard galvanized steel. Environmental factors like coastal salt spray accelerate rusting in non-coated metals, making our PVDF/SMP coatings essential for longevity.

Identification System

• Laser Marking: Batch codes (e.g., DX51D+AZ150) and compliance labels (EN 10346, ASTM A792).
• QR Tracking: Links to mill certificates, salt-spray test reports (1,000+ hours), and installation guidelines.
• Color Coding: Edge stripes denote thickness (e.g., red = 0.5 mm, blue = 0.8 mm).

Manufacturing Excellence

Process Flow

1. Material Sourcing: Prime-grade steel coils from ISO-certified mills.
2. Surface Prep:
   • Galvanizing: Hot-dip immersion at 450°C, zinc coating control via air knives.
   • Coating: PVDF, SMP, or HDP layers applied via reverse-roll coater (5–25 µm thickness).
3. Corrugation: 26-stage hydraulic press forms trapezoidal/arc profiles (wave height: 15–40 mm).
4. Quality Assurance: Eddy-current testing for coating uniformity; bend tests per ASTM A370.

Customization Options

• Profiles: Trapezoidal, double-layer, glazed tile, solar-ready brackets.
• Colors: 200+ RAL shades with 20-year fade warranty.
• Pre-Drilled Holes: For fast installation with stainless steel fasteners.
