Import 3003 H24 Color Coated Aluminum Coil For — Buy in wholesale FOB from Supplier in China

Shandong Hengzhan Building Materials Co., Ltd. produces 3003 H24 color coated aluminum coil specifically engineered for roofing applications, with raw material sourced from recognised Chinese smelters including Southwest Aluminum, South Mountain, China Aluminum and Ruimin. The coil is available in thickness from 0.14 mm to 3.0 mm and width from 40 mm to 1600 mm, with length cut to customer requirements. The H24 temper, signifying strain-hardened and partially annealed condition, delivers the strength and formability balance necessary for profiled roofing sheets and standing seam systems. Inner diameter options are 150 mm, 405 mm, 500 mm, 505 mm and 510 mm, accommodating various decoiler configurations common in roll-forming operations.

The coating system encompasses single-coated, double-coated and triply-coated constructions using PE or PVDF resin systems, with painting thickness exceeding 18 microns for PE and 25 microns for PVDF. Paint suppliers include PPG, Becker, Nippon, AkzoNobel and Valspar, with gloss levels adjustable from 10 percent to 90 percent. Decorative finishes extend beyond solid colour to embossed, stone grain, wood grain, brushed, mirror and spectra effects, with new colours developed on request. Impact resistance meets 50 kg per cm per ASTM D-2794:1993 without peeling or cracking, and T-bend performance is rated at 2T, indicating the minimum bend radius relative to material thickness before coating failure.

This coil format is suited to continuous roll-forming into corrugated, trapezoidal or standing seam roof profiles for industrial, commercial and residential buildings. The 3003 alloy's inherent atmospheric corrosion resistance and the protective colour coating extend service life in varied climates. Buyers should specify exact thickness, width, colour code and finish type when inquiring, and confirm whether protective film with custom logo printing is required. The broad inner diameter range allows matching to existing processing equipment, reducing changeover downtime.

Shandong Hengzhan Building Materials Co., Ltd. is situated in the National Hi-Tech Industrial Development Zone, Linyi, Shandong Province, 276000, China. The company holds a harbor trust tier with a response rate of 0.00 percent and no recorded average response hours. Its specialisation lies in building materials, with coated aluminum coil for roofing representing a core product line. The listing emphasises flexibility in colour, finish and coating configuration rather than volume capacity or vertical integration details.

No information is provided on year of establishment, registered capital, factory floor area, employee numbers, annual turnover, export markets served, or quality management certifications such as ISO 9001. Specific roofing project references or client names are absent. Buyers should independently verify business licence status, production capacity in tonnes per annum, and whether the company operates its own coil coating line or sources coated substrate from a third party. The listed raw material suppliers suggest domestic mill relationships, but confirmation of mill test certificate traceability is recommended.
