Company introduction
Sanli Precision Steel Tube Processing Factory was established in October 2003 and is located in Huadu District, Guangzhou, Guangdong, China. With over 20 years of development, we have grown into a specialized manufacturer with more than 10, 000 m² of production area. Our management and core engineering team comes from the "Guanggang" technical system and carries forward rigorous industrial discipline and standardized manufacturing practices, helping us control quality consistently from raw-material evaluation to final inspection. We focus on small-diameter, thin-wall precision tubes, and most orders are customized for overseas buyers and component manufacturers (non-standard sizes, special materials, and flexible batches). Our main product scope includes: • Seamless precision tubes (cold drawn / cold rolled): OD 5-114 mm, WT 0.3-20 mm • Welded tubes: OD 18-42 mm, WT 1-6 mm • Stainless steel tubes and aluminum tube processing, plus cutting/length customization and export packaging options Typical materials we process include carbon steel (10#, 20#, 35#, 45#), alloy steel (40Cr, 30CrMo, 35CrMo, 38CrMo), and stainless steel (201, 304, 316L). Depending on size and route, we support tight dimensional control (e. g., H8/H10) and stable surface finish targets (e. g., Ra 0.8-1.6), helping customers reduce downstream machining losses and improve assembly consistency. To deliver tubes in the exact condition required by your production line, we operate a full processing chain including pickling, annealing, straightening, cold drawing, cold rolling, and welding. Our inspection capability covers chemical composition analysis, dimensional measurement, eddy-current flaw detection, hardness testing, and tensile/strength testing. Upon request, we can provide QC documents such as chemistry and dimensional reports, and we support third-party inspection arrangements. We keep improving process stability through equipment upgrading and better on-site management, and we support export needs such as quick quotation, engineering communication, and customized marking. Our precision tubes are widely used in home-appliance components (AC sleeves, connectors, fan shafts, condenser tubes), hydraulic and gas-spring parts, automotive and e-bike components, medical devices, molds, and general machinery. Share your drawings, tolerances, and application requirements-our engineers will recommend a practical process route and sampling plan before mass production, and we will work with you to achieve stable quality and reliable lead times.
