从China供应商批发进口3003 H24 Pvdf Prepainted Aluminum Sheet — FOB条款

This 3003 H24 PVDF prepainted aluminum sheet uses AA3003 alloy in the strain-hardened H24 temper, supplied with a polyvinylidene fluoride (PVDF) coil coating applied via continuous roll coating after chromate pretreatment. The source lists available substrates as AA1100, 3003, 3004 and 3105, with this specific SKU indicating the 3003-H24 combination that balances moderate strength with excellent formability. The PVDF layer provides the characteristic 15-plus year colour retention for external applications, operating across a stated temperature range of minus 50 degrees Celsius to 80 degrees Celsius without degradation.

The colour palette covers more than 1000 RAL shades alongside wood grain, stone grain and embossed gloss finishes, with protective PVC film (0.04-0.1 mm) applied to the surface for transit and installation protection. The coating system exhibits strong acid and alkali resistance, UV stability and weathering performance derived from the fluorocarbon chemistry. The base metal offers a density of approximately 2.73 g per cubic centimetre typical for 3003 alloy, with the H24 temper indicating half-hard mechanical properties after work hardening and partial annealing.

Architectural fabricators, cladding contractors and signage manufacturers form the core buyer base, deploying this material for curtain walls, roofing, interior panels, composite panels, ceiling systems, advertising boards and engineered square tubing. The 100 percent recyclability of the aluminum substrate, combined with the absence of rust, supports green building certifications. Buyers should confirm exact coil width, sheet thickness and coating thickness with Shandong Hengzhan, as these dimensional parameters are not stated in the source data.

Shandong Hengzhan Building Materials Co., Ltd. operates from the National Hi-Tech Industrial Development zone in Linyi, Shandong Province, China, postal code 276000. The company holds a Harbor trust tier on the platform, though its response rate currently reads zero percent with zero average response hours recorded. This profile indicates a listed supplier with unverified engagement metrics rather than an actively responding entity.

The source description positions the firm as a roll-coated aluminum coil and sheet specialist, offering colour coating, embossing and custom protective film services. No verified production capacity, annual revenue, employee headcount, certification list or client references appear in the provided data. Buyers should treat unconfirmed claims as unverified and conduct independent due diligence before committing to orders.
