Customizable Tin Roofing Sheets | Color-Coated Options

Product Overview
Our kalkreuth roofing and sheet metal solutions combine precision engineering with vibrant aesthetics, offering color-coated tin roofing sheets tailored for residential, commercial, and industrial applications. Designed to meet SGCC (JIS G3302) and EN 10346 standards, these sheets excel in durability, weather resistance, and design flexibility. Available in galvanized, stone-coated, and PVDF-painted variants, they redefine modern roofing with competitive metal roofing cost per sheet and ease of installation.

Technical Specifications

Certified to ASTM, ISO 9001, and Miami-Dade HVHZ hurricane codes.

Performance Attributes

Tensile Strength

Our kalkreuth roofing and sheet metal sheets achieve tensile strengths of 380–700 MPa (DX51D) and 550–620 MPa (SGCC), ideal for high-load environments like hurricane-prone regions. The dual-phase microstructure balances ductility and rigidity, resisting deformation under wind loads exceeding 150 mph.

Bendability

Precision roll-forming technology enables bending radii as low as 1.2× thickness without cracking, critical for seamless nailing roof sheeting and complex geometries. Cold-rolled edges ensure uniformity, reducing material waste during installation.

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.

Anti-Corrosion Mechanism

Stainless steel’s chromium oxide layer (≥10.5% Cr) provides passive protection against oxidation. Galvalume coatings (55% Al, 43.4% Zn, 1.6% Si) offer 4× longer lifespan than standard galvanized steel. Environmental factors like chloride exposure (coastal areas) 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.
