Versatile Color Coated Steel Coil: Properties and Specifications
Dinglian Co., supply Color Coated Steel Coil, a versatile material made by applying organic coatings to steel substrates like galvanized or galvalume. This process enhances corrosion resistance, durability, and aesthetics. Commonly used in construction for roofing, wall panels, and doors, it's also found in appliances and furniture. Classifications vary by coating type (polyester, epoxy, PVDF), substrate, and application, offering diverse properties and finishes.
Specifications
- Substrate Type:Common substrates include galvanized steel (GI), galvalume steel (GL), and cold-rolled steel (CR), each offering varying levels of corrosion resistance and formability.
- Substrate Thickness:Typical thicknesses range from 0.15 mm to 1.5 mm, influencing the coil's strength, weight, and application suitability.
- Coil Width: Standard widths generally range from 600 mm to 1500 mm, accommodating diverse manufacturing and end-use requirements.
- Coil Inner Diameter: Common inner diameters are typically 508 mm or 610 mm, designed to fit standard uncoilers and processing equipment.
- Coil Outer Diameter: Outer diameter varies based on thickness and weight, generally ranging from 1000 mm to 1800 mm for manageable handling.
- Coating Type: Polyester (PE), silicone modified polyester (SMP), polyvinylidene fluoride (PVDF), and epoxy are common coatings, each with specific durability and weather resistance.
- Coating Thickness: Total coating thickness usually ranges from 15 μm to 40 μm, applied in single or multiple layers for desired protection and finish.
- Color Range: A wide spectrum of colors is available, often based on RAL or custom color charts, providing aesthetic flexibility for various applications.
- Surface Finish: Options include smooth, embossed, or textured finishes, affecting the visual appearance and surface properties of the coated steel.
- Zinc/Aluminum Coating: For GI, zinc coating weights typically range from Z80 to Z275 (g/m²). For GL, aluminum-zinc coatings often range from AZ50 to AZ150 (g/m²).
