Our steel structures serve as the backbone for diverse projects including skyscraper frames, bridge girders, industrial plants, stadium trusses, offshore oil rigs, warehouse systems, wind turbine towers, modular buildings, airport hangars, and heavy machinery bases. Suitable for both large-scale projects and custom small builds.
We offer strong design customization capabilities using AutoCAD, SketchUP, Tekla, PKPM and 3D modeling technologies. Our engineering team adapts to unique load requirements, architectural styles, and site constraints to deliver personalized, efficient, and compliant steel structure systems for industrial plants, commercial buildings, and special structures.
Our production begins with rigorous quality inspections of raw materials. Components are precisely cut using CNC plasma or laser cutting, then formed through bending, rolling, or punching. Critical welding joints undergo ultrasonic testing. After assembly, components receive surface treatment including shot blasting and protective coatings. Final quality checks include 3D scanning, load testing, and compliance audits before packaging and transportation.
Upon fabrication, Tsin Steel Structure employs a standardized transportation protocol to ensure components arrive intact and on schedule. All steel members are meticulously packaged using anti-rust paper and steel rings to prevent damage during transit. For large or delicate parts, additional protection such as plywood wooden boxes or steel crates is used, adhering to international packaging regulations. Loading procedures involve securing components with specialized fixtures to avoid shifting, while transportation routes are optimized to bypass high-risk areas and ensure roadworthiness. Real-time GPS tracking systems monitor shipments, providing clients with updates on delivery progress. Compliance with ISO 9001-certified logistics standards guarantees seamless coordination between manufacturing facilities and project sites, minimizing delays and reducing handling risks.
Tsin’s quality control system integrates multi-stage inspections to uphold structural integrity and compliance with global standards. Raw materials undergo rigorous chemical composition analysis and physical property testing upon procurement, verified through certified material test reports (CMTR). During fabrication, AWS-certified welding inspectors conduct visual examinations and non-destructive testing (NDT), including ultrasonic testing (UT) and magnetic particle testing (MT), to detect weld defects. Final inspections verify dimensional accuracy using laser scanning and ensure coating thickness meets design specifications through electronic gauges. All products are also subjected to adhesion tests and salt spray corrosion resistance evaluations to guarantee long-term durability. Complying with GB 50205-2020 and ISO 9001:2008 standards, Tsin issues detailed inspection reports, including NDT results and coating performance data, to validate compliance and customer satisfaction.
