Key Attributes
-
Tensile Strength:
Our steel coils exhibit a tensile strength range of 515–860 MPa, ensuring structural integrity under high stress. This property is critical for applications requiring resistance to deformation, such as in seismic zones or heavy-load environments. -
Bend Strength:
With a bend strength of **≥450 MPa, the material withstands repeated flexing without cracking. This makes it suitable for curved architectural elements, HVAC ducts, and automotive components. -
Weight Calculation:
Formula: Weight (kg) = Length (m) × Width (m) × Thickness (mm) × Density (7.93 g/cm³) ÷ 1000.
Example: A 1m × 1m × 1mm coil weighs approximately 7.93 kg. -
Marking Standards:
Coils are marked per ASTM A480/A480M, including grade, thickness, coating type, and batch number. Laser etching ensures permanent identification. -
Stainless Steel Rusting Causes:
While stainless steel is highly corrosion-resistant, rust may occur under extreme conditions:- Chloride Exposure: Prolonged contact with seawater or de-icing salts can degrade the passive oxide layer.
- Mechanical Damage: Scratches or abrasions expose the underlying metal to oxidation.
- Improper Cleaning: Residual iron particles from tools can trigger galvanic corrosion.
Advanced Manufacturing Process
Our china color coated galvanized steel coil undergoes a 6-stage production:
- Galvanization: Hot-dip galvanizing with zinc-aluminum alloy for base corrosion protection.
- Surface Treatment: Chromium passivation to enhance coating adhesion.
- Primer Application: Eco-friendly epoxy primer for UV resistance.
- Color Coating: High-precision PVDF or polyester coil coating colors applied via roller coating.
- Curing: Infrared oven curing at 220°C for uniform finish and hardness.
- Quality Inspection: Eddy-current testing for coating thickness consistency and defect detection.
