Color Coated Aluminum Coil - Premium Pre-Painted Aluminum Coil for Construction & Manufacturing

Color coated aluminum coil represents a versatile pre-finished aluminum product featuring factory-applied organic coatings that deliver exceptional durability and aesthetic appeal. Engineered for architects, construction contractors, and manufacturing professionals, these coils combine lightweight aluminum substrate with high-performance paint systems to serve demanding applications in building facades, roofing systems, and industrial equipment. With superior corrosion resistance and design flexibility, color coated aluminum coils provide cost-effective solutions for projects requiring both structural integrity and visual impact.

What is Color Coated Aluminum Coil?

Color coated aluminum coil is a continuously processed aluminum product where base aluminum alloy coils undergo chemical pretreatment followed by precision application of primer and topcoat layers through roll-coating technology. The coating process typically involves alloys such as 1100, 3003, or 5052, with coating thickness ranging from 18 to 25 micrometers for standard applications, conforming to ASTM B209 specifications for aluminum sheet and coil dimensions.

Color Coated Aluminum Coil Technical Specifications

Standard color coated aluminum coils are manufactured with alloy tempers H14, H16, or H18, featuring thickness ranges from 0.20 mm to 1.50 mm and widths up to 1,600 mm. Coating systems include polyester (PE) with 60-degree gloss retention per ASTM D523, polyvinylidene fluoride (PVDF) offering 20-year weatherability according to AAMA 2605, and polyurethane (PU) formulations. The substrate demonstrates tensile strength of 130-165 MPa for 3003-H14 alloy per ASTM B209, with coating adhesion meeting ASTM D3359 classification 4B minimum.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is established at 5 metric tons per color and specification combination, though we accommodate smaller trial orders of 2 metric tons for new customer evaluation purposes, subject to premium pricing adjustments to offset coil coating line setup procedures.

Do you provide material test certificates?

We issue comprehensive mill test certificates with every shipment, documenting alloy composition verified through optical emission spectrometry per ASTM E1251, mechanical properties including tensile strength and elongation per ASTM E8, and coating performance data encompassing pencil hardness (ASTM D3363), MEK double rubs (ASTM D5402), and salt spray resistance (ASTM B117) for 1,000-hour exposure cycles.

What is the typical delivery time?

Standard color selections from our inventory range ship within 15-20 business days FOB our coating facility, while custom color formulations require 25-30 business days to accommodate color matching protocols, coating system optimization, and quality verification procedures including accelerated weathering testing per ASTM G155.

Can you cut to custom sizes?

Our precision slitting capabilities accommodate custom widths from 100 mm to 1,600 mm with tolerance of ±1.0 mm, utilizing carbide slitting knives to maintain edge quality without coating damage. We also provide cut-to-length services for sheet dimensions up to 3,000 mm × 1,600 mm, with cutting tolerance of ±2.0 mm per ASTM B209 requirements, suitable for immediate fabrication without secondary processing.
