As a specialized steel structure manufacturer in China, LWY Steel Structure operates an advanced production factory equipped with heavy-duty pipe-intersecting cutting machines, multi-spindle CNC drills, and automated submerged arc welding lines. Serving as a trusted direct supplier for steel structure gymnasium, we control the entire workflow from structural modeling to complete factory trial pre-assembly.
Designed from the general contractor's perspective, the primary frame integrates seamlessly with overhead catwalks, heavy scoreboards, lighting rigs, and acoustic insulation roof panels. Every structural member, purlin, and gusset plate is factory pre-punched, shot-blasted, and clearly inkjet-labeled according to detailed erection blueprints. Utilizing 100% high-strength bolted connections, local construction teams can erect the gymnasium structure rapidly without expensive specialized field welding.

This steel structure gymnasium adopts large clear-span design without intermediate columns, featuring fast installation, good seismic resistance and flexible space layout, suitable for multiple scenarios.
Used for primary, secondary and university indoor sports venues. Support daily PE teaching, ball games training, school sports meetings, student assemblies and graduation events.
Build comprehensive indoor gyms for cities and communities. Host amateur competitions, public fitness activities and mass sports events for local residents.
Work as professional training halls for sports teams and sports schools. Meet training demands for basketball, volleyball, badminton and other sports.
Except for sports, the open space can be reused for concerts, cultural performances, trade exhibitions and large-scale conferences to improve overall venue utilization.
Fit for commercial sports clubs and indoor sports parks. Also serve as staff activity venues for factories and industrial parks for recreation and team-building.


Our steel structure gymnasium adopts pre-engineered large-span steel systems, calculated for local wind, snow and seismic loads. Main components are factory prefabricated for fast on-site assembly.
Choose portal rigid frame, space truss or space frame according to span requirement. Made of Q235B / Q355B H-section steel columns and rafters. It delivers large column-free inner space, bears gravity, wind and seismic loads, and transfers all loads down to building foundations.
Consists of galvanized C/Z purlins, tie rods, angle steel bracings and knee braces. This sub-system stabilizes the main frame, supports roof and wall panels, and enhances overall building rigidity.
Roof and wall adopt rock-wool / PU / EPS sandwich panels or profiled steel sheets. Matched with gutters, downpipes and sealing accessories. Good thermal insulation, waterproofing and noise reduction to create comfortable indoor sports environment.
High-strength bolts for field connections. Main steel members go through shot-blasting anti-rust treatment, with paint or hot-dip galvanized surface finish, extending service life of the whole gymnasium.
Located in Qingdao West Coast New Economic Zone, LWY Steel Structure enjoys convenient access to railways, airports and Qingdao Port for efficient global logistics.
Founded in 2003, we are a national high-tech & Qingdao specialized-innovative enterprise. Our full-scope business covers design, R&D and manufacturing of steel structures, workshops, prefab houses, modular buildings and offshore platform components.
We have a complete talent team of 200 staff, including professional engineers, management and construction workers. Supported by advanced production machinery such as laser cutters, CNC cutting & drilling devices, automatic welding and shot-blasting equipment, we deliver an annual steel processing capacity above 20,000 tons plus 500,000 ㎡ of maintenance materials.
Drawing experience from offshore oil engineering, we keep optimizing product safety, technical performance and green construction. We supply both standard and custom metal components. Our products are exported to more than 50 countries and regions worldwide.
We stick to quality-oriented manufacturing, strict safety management and customer-first service, striving to fully satisfy global clients' project requirements.





A1: Steel gyms adopt large clear-span design with no middle columns, offering wider usable space. They feature lighter weight, better earthquake resistance, wind resistance and thermal insulation. Meanwhile, they have shorter construction period, lower overall cost, recyclable materials and greener construction.
A2: Yes. All specifications are fully customizable. We design the span, height, floor area, door/window position and internal functional area according to customers' site conditions, usage scenarios and local building load standards (wind, snow and seismic load).
A3: Steel components are prefabricated in the factory, only needing on-site assembly. Compared with concrete buildings, the construction period is shortened by 50%. A standard gymnasium can be completed within 30–60 working days after all materials arrive at the site.
A4: We adopt high-quality PU/EPS/rock wool sandwich panels for roof and wall enclosure. The complete sealing system realizes excellent waterproof and dustproof effect. The sandwich core material ensures good thermal insulation and heat preservation, and effectively reduces indoor and outdoor noise transmission, meeting indoor sports venue standards.
A5: The main steel frame adopts shot blasting rust removal and professional anti-corrosion painting or hot-dip galvanizing treatment. The overall service life can reach 50 years under normal use and regular maintenance.
Our structural design strictly complies with international building codes. It can adapt to different wind load, snow load and seismic grade requirements of various countries and regions, ensuring long-term stable and safe operation of the venue.
