Guojian Steel independently manufactures various finished Truss Steel Structure and component parts—including tubular trusses and angle-steel trusses—within its own production facilities. These products address the practical needs for load-bearing roofing, spatial support, and rapid construction in large-span buildings, making them ideal for industrial plants, stadiums, municipal corridors, and similar projects. We operate established production lines for cutting, welding, and anti-corrosion treatment, strictly adhering to national quality standards. We also assist clients with detailed design refinement to minimize on-site workload. We offer flexible supply capabilities, handling orders of all sizes while ensuring precise component manufacturing; this effectively lowers overall project costs and guarantees timely completion.
Base Material: Q235B or Q355B carbon structural steel (compliant with national standards); custom material specifications available upon request;
Surface Treatment: Options include hot-dip galvanizing, anti-rust primer plus topcoat spraying, and fire-resistant coatings;
Product Types: Circular tube trusses, angle-steel trusses, triangular trusses, and custom-shaped trusses;
Manufacturing Process: CNC cutting, automated welding, grinding/derusting, flaw detection, and pre-assembly;
Applicable Span: Suitable for large-span projects (10–60m); supports non-standard custom designs based on drawings;
Supply Mode: Delivery of fully assembled units or disassembled components; supports scheduling for large-volume orders;
High Load-Bearing Capacity for Large Spans: Truss structures offer a high strength-to-weight ratio and excellent overall rigidity. They minimize the need for intermediate columns, creating expansive interior spaces that meet the requirements of stadiums and industrial facilities.
Factory Pre-fabrication Reduces On-Site Construction Time: All components are pre-fabricated at Guojian Steel’s facility; on-site work is limited to bolting and assembly. This reduces on-site welding and significantly shortens the overall construction schedule.
Durable Anti-Corrosion Performance: Hot-dip galvanizing options provide resistance to rain-induced corrosion, making the structures suitable for outdoor municipal projects and open-air canopies. This extends the structure's service life and reduces long-term maintenance costs. Flexible, non-standard customization for diverse projects: We support manufacturing based on provided drawings and offer detailed design services. Custom-shaped trusses can be tailored to specific load, dimension, and aesthetic requirements—going beyond standard specifications.
Strict quality control: We implement rigorous checks at every stage—from raw material inspection and post-welding flaw detection to final product verification—ensuring project safety by preventing the shipment of non-compliant products.
Industrial Buildings: Load-bearing trusses for large-span factory and workshop roofs;
Public Venues: Main roof trusses for stadiums, convention centers, and exhibition halls;
Municipal Projects: Pedestrian overpasses, sunshades, canopies, and landscape structures;
Transportation Infrastructure: Bridge support trusses, toll station roofs, and parking shelter frameworks;
Manufacturer: Guojian Steel Co., Ltd. operates its own steel structure fabrication workshop equipped with a full suite of CNC machinery. We handle the entire production process in-house—from raw material intake to finished product shipment—without outsourcing, ensuring quality control at every step. Expert Design Support: Our team of Truss Steel Structure technicians assists with detailed design, structural optimization, and meeting specific project technical requirements. Flexible Order Handling: We accommodate both large-scale project orders and small-to-medium custom orders, with flexible scheduling to guarantee timely delivery.
Ordering Methods: Bulk purchasing, quote-based ordering, custom fabrication from drawings, and wholesale processing; quotes provided upon receipt of drawings or project specifications;
Delivery Lead Time: Calculated based on order volume; large-volume orders receive scheduling priority to ensure on-time delivery;
Packaging & Transport: Components are securely bundled; options include full-truckload shipping or split-load transport for individual parts to minimize transit damage;
After-Sales Support: Provision of material certificates and factory inspection reports; technical support available for installation-related inquiries.
A: Yes. Guojian Steel can fabricate custom-shaped trusses based on project drawings, adjusting cross-sections, heights, and overall dimensions.
A: For outdoor applications, hot-dip galvanizing is the preferred choice due to its superior corrosion resistance and longer lifespan; for indoor projects, painting is an option that offers better cost-efficiency.
