Product Introduction
Modern large‑span public buildings such as airport terminals, exhibition halls and logistics warehouses require reliable structural solutions to achieve spacious interior space without dense intermediate columns. Our steel pipe truss is a space frame structural system assembled by high‑strength steel tubes through welding and bolt connection. It is widely adopted for airport terminal roofs, large‑venue canopies and industrial workshop roofing projects. The structure delivers excellent geometric stability, adapting to complex building outline designs. Each component undergoes precise pre‑processing in‑factory before transportation to construction sites, which greatly shortens on‑site installation cycles. This structural form perfectly matches the construction requirements of large‑volume public infrastructure projects just like Mudan Airport terminal building roof systems.

Product Advantages
Superior mechanical performance
The steel pipe truss features reasonable force transmission paths. Tension and pressure are evenly distributed across pipe members, bringing strong load‑bearing capacity for large‑span roofs.
01
Light self‑weight
Compared with traditional concrete structures, it cuts overall foundation investment, suitable for various geological site conditions.
02
Flexible shaping
Supports arc‑shaped, polygonal and irregular curved outlines, meeting diversified architectural aesthetic requirements.
03
Good anti‑corrosion performance
Multiple surface‑treatment options resist humidity, dust and atmospheric corrosion for long‑term outdoor service.
04
Fast construction
Modular prefabrication reduces high‑altitude on‑site work volume and shortens overall project schedule.
05
Company Strength
We are a professional manufacturer engaged in large‑span steel structure manufacturing for many years. Our factory owns complete numerical‑control cutting, pipe‑processing and welding production lines. We have participated in multiple key public‑infrastructure construction projects similar to airport terminal constructions. Our technical team consists of structural engineers with rich overseas‑project experience. Every batch of components strictly passes non‑destructive welding testing before delivery. We keep complete production inspection records for each order to guarantee product consistency. We can independently complete the whole workflow including scheme optimization, drawing deepening, component production and technical guidance.
Company Service
