Technical clarity on procurement, surface durability, toll manufacturing, and international export procedures.
A: Black anodizing creates an electrochemical oxide coat integrated directly into the aluminum surface, providing a metallic luster, extreme scratch resistance, and zero risk of peeling. Black powder coating applies an organic resin layer (60–80 µm) over the metal, offering a wider choice of gloss levels (matte, satin, textured) and high impact resistance, ideal for outdoor fences and pergolas.
A: Yes. We offer comprehensive OEM/ODM services. Send us your DWG, STEP, or IGES files, and our engineering team will perform die-flow analysis, generate extrusion tooling within 48 to 72 hours, and deliver physical samples in under 7 days.
A: For marine or coastal projects within 1 km of ocean waters, we recommend our PVDF fluorocarbon spraying or QUALICOAT Class 2 anodizing (20+ µm). These treatments exceed 3,000 to 4,000 hours of neutral salt spray testing (ASTM B117) without pitting or corrosion.
A: Standard profile MOQs start at 500 kg per section for existing molds, and 1,000 kg for custom tooling. Typical production lead times range between 15 to 20 days. Emergency fast-track production is available for standardized models using our stock billets.
A: Absolutely. Our extrusions conform to EN 755 / EN 12020 dimensional tolerances, ASTM B221 structural standards, and QUALICOAT surface specifications. Full chemical composition and mechanical test certificates (MTC) are provided with every shipment.
A: Each individual profile is wrapped with protective PE film or interleaved with non-abrasive paper. Bundles are enclosed in shrink-wrap plastic, reinforced with corner guards, and packed inside steel-framed fumigated wooden crates suitable for heavy container loading.
