Manufacturing excellence is the foundation. What distinguishes a true industrial partner is the capacity to deliver steel pipes that arrive ready for immediate integration—prepared, protected, and precisely as specified. At SHINESTAR STEEL GROUP CO., LTD., our services transform standard products into project-ready solutions.

As a core pre-processing procedure, we offer high-precision custom cutting for medium and heavy plates, alloy plates, steel pipes and profiles. Equipped with CNC flame, fine plasma and laser cutting technologies plus intelligent nesting systems, we ensure smooth, burr-free cuts and high material utilization. Our closed-loop CNC process controls dimensional accuracy strictly, providing consistent precision blanks for subsequent processes.

Our professional production line provides internal and external anti-corrosion coating for industrial pipes using the industry-standard 3PE process. We implement closed-loop management throughout the process, strictly controlling coating thickness, bonding strength and corrosion resistance. The dense, anti-aging coating extends pipeline service life, meeting the needs of oil and gas, chemical and municipal projects.

As a key pre-welding process, we offer precise beveling for steel pipes, plates and fittings of various materials. Equipped with CNC beveling machines, we process V-type, U-type and other bevel types with high consistency and accuracy. Our service connects seamlessly with cutting and welding, ensuring welding quality and reducing defects for pressure vessels and engineering pipelines.

We provide high-precision threading for various steel pipes, including OCTG, complying with API, BSP and NPT standards. Using CNC threading machines and closed-loop detection, we ensure excellent thread accuracy, sealing performance and wear resistance. Our customized service matches subsequent processes, ensuring tight connection of pipeline systems under harsh working conditions.

We have professional certified welders and advanced equipment, covering submerged arc, gas shielded and argon arc welding. With full-process quality control and NDT inspection, we ensure defect-free welds with high strength. Our assembly service achieves precise component integration, providing one-stop solutions for large-scale projects like oil and gas pipelines.

We specialize in customized rolling and bending of steel pipes, plates and profiles, including seamless, stainless and alloy steel products. With high-precision CNC equipment, we achieve accurate forming of different curvatures and angles without surface defects. Our professional team formulates personalized schemes to match project needs, widely applied in petroleum, municipal and bridge fields.
