Explore our core OEM/ODM product range manufactured in Foshan. Fully compliant with ASTM A554 dimensional standards, featuring optical-grade mirror polishing, precise wall control, and superior ductility.
Analyzing procurement trends, metallurgical innovations, and surface finish physics driving modern architectural, medical, and industrial ODM applications.
Mirror polishing is not merely aesthetic—it is a critical mechanical process. By grinding surface roughness down to Ra ≤ 0.02 µm (800# Super Mirror), micro-voids and surface fissures are eliminated. This prevents microscopic chloride ion accumulation, dramatically boosting pitting resistance ($PREN > 25$ for 316L) while delivering distorted-free optical reflection for luxury architectural installations.
Situated in the heart of Foshan—the epicenter of global stainless steel manufacturing—our ODM facilities leverage integrated raw material supply chains from premier steel mills (TISCO, POSCO, Baosteel). We achieve unprecedented cost efficiency, fast-track tooling modification, and strict batch-to-batch chemical stability across all 200, 300, and 400 series stainless alloys.
Advances in high-frequency Plasma TIG welding, automated inner seam planishing (hammering), and bright annealing have rendered modern welded stainless steel tubes chemically and mechanically equivalent to seamless tubes for structural and decorative uses, while offering 30–40% cost reductions and superior wall uniformity.
Continuous investment in automated production tech, inline optical testing, and metallurgical quality control.

Custom tube engineering engineered to meet rigorous performance demands across five major global industries.
Mirror polished ASTM A554 round, square, oval, and D-shape tubes provide high structural rigidity and flawless aesthetics. Combined with PVD Titanium Vacuum Coating (Rose Gold, Champagne Gold, Black Titanium, Brass), our tubes resist fingerprint smudges and abrasive cleaning reagents in high-end commercial interiors.
Precision 304/316L medical tubing designed for hospital bed rails, grab bars, and IV stands. Smooth $Ra \le 0.2\,\mu\text{m}$ surfaces eliminate microbial harboring zones, permitting rapid chemical disinfection while passing rigorous $90^\circ$ mandrel bending without flattening.
Engineered 409L and 304 exhaust tubing capable of withstanding $700^\circ\text{C}$ thermal cycling. Precision wall uniformity guarantees seam stability during hydroforming and high-speed CNC expansion for exhaust mufflers, catalytic converter housings, and chassis frames.
Ultra-straight round tubing featuring Total Indicator Runout (TIR) controlled within $\le 0.15\,\text{mm/m}$. Eliminates rotational vibration in high-speed logistics sorting conveyors, food wash-down lines, and packaging machinery.
Molybdenum-doped 316L tubing subjected to post-weld pickling and passivation treatments. Tested under neutral salt spray (ASTM B117) exceeding 500 hours without red rust, protecting yacht handrails, coastal shower fixtures, and marina hardware.
In-house CNC secondary processing converts mill lengths into ready-to-assemble components: precision laser cutting, multi-axis mandrel bending, end flaring, necking, slot punching, and end-cap orbital welding.
Every single coil is tracked from raw material slitting down to final export container sealing under our ISO9001 certified protocol.
Discover specialized profiles, automotive exhaust tubing, medical grab bar tubing, and custom CNC fabricated components engineered to exact global specifications.
Facilitating seamless international procurement for enterprise buyers across North America, Europe, Australia, and the Middle East.
All production lots comply with ASTM A554, ASTM A249, ASTM A269, EN 10217-7, and JIS G3446 standards. Supplied with full traceability reports including MTC EN 10204 3.1, ISO9001:2015 registration, and RoHS / REACH chemical safety compliance.
With an extensive internal tooling library of over 500 roll-forming dies, we engineer custom elliptical, flat-oval, triangular, and slotted profile tubes without initial tooling fees for most standard architectural sizes.
Standard production lead time is strictly maintained at 15 days. Low flexible MOQs starting at 500 kg per size and finish enable streamlined inventory management for global distributors and OEM factories.
