Ultimate China Color Coated Steel Coil | Factory-Priced Durability

Ultimate China Color Coated Steel Coil | Factory-Priced Durability

​Product Overview

Our ​china color coated steel coil combines cutting-edge manufacturing with architectural-grade performance, designed for global construction, automotive, and industrial applications. Leveraging advanced ​color coated aluminium coil technology, our products deliver unmatched corrosion resistance, vibrant aesthetics, and structural reliability. Ideal for roofing, façades, HVAC systems, and transportation components, these coils are engineered to withstand extreme environments while maintaining cost efficiency.

​Technical Specifications

​Key Technical Attributes

1. ​Tensile Strength:
   Our ​color coated coil achieves a tensile strength range of ​300–450 MPa, ensuring structural integrity under heavy loads and dynamic stress. This property is critical for applications like high-rise buildings, bridges, and automotive frames, where material deformation resistance directly impacts safety and longevity.

2. ​Bend Strength:
   With a bend strength of ​≥350 MPa, our coils withstand repeated flexing without cracking. This makes them ideal for curved architectural elements (e.g., airport roofs, stadium domes) and complex automotive parts. The ​color coated aluminium coil layer further enhances flexibility by reducing brittleness in low-temperature environments.

3. ​Marking & Identification:
   Coils are marked per ​ASTM A480/A480M standards, including:

   • Laser-etched batch numbers and production dates for traceability.
   • QR codes on the coil edge for instant verification of material grade, coating type, and compliance certifications.
   • Color-coded labels (e.g., blue for PVDF, gray for polyester) to simplify inventory management.

4. ​Weight Calculation:
   Formula: ​Weight (kg) = Length (m) × Width (m) × Thickness (mm) × Density (7.85 g/cm³) ÷ 1000.
   Example: A 1.5m × 1m × 0.5mm coil weighs ​5.89 kg. Custom calculations for irregular shapes are available upon request.

5. ​Stainless Steel Rusting Causes:
   While stainless steel is inherently corrosion-resistant, rust may occur under specific conditions:

   • ​Chloride Exposure: Coastal or industrial environments with high salt or chemical content degrade the passive chromium oxide layer.
   • ​Mechanical Damage: Scratches from improper handling expose the substrate to oxidation.
   • ​Galvanic Corrosion: Contact with dissimilar metals (e.g., iron tools) triggers electrochemical reactions.
   • ​Temperature Fluctuations: Condensation in humid climates accelerates oxidation at micro-crack sites.

​Advanced Production Process

Our ​china color coated steel coil undergoes a 7-stage manufacturing workflow:

1. ​Base Material Preparation:
   Cold-rolled or hot-dip galvanized steel is cleaned via alkaline degreasing and phosphating to remove impurities.

2. ​Primer Application:
   An epoxy-based primer (15–25µm) is roll-coated to enhance adhesion and UV resistance.

3. ​Top Coating:
   High-precision PVDF or polyester ​color coated coil layers (20–30µm) are applied using electrostatic spraying for uniform coverage.

4. ​Curing:
   Infrared ovens bake the coating at 220°C–250°C to achieve cross-linking and hardness (≥60 HRB).

5. ​Quality Assurance:
   Eddy-current sensors monitor coating thickness (±2µm tolerance), while spectrophotometers verify color consistency (ΔE ≤0.5).

6. ​Packaging:
   Coils are wrapped in waterproof paper + PVC film + steel straps to prevent transit damage. Custom packaging (e.g., wooden crates) is available for fragile finishes.
