• Primary Rigid Frames: Fabricated from steel plates (Q235B/Q345 grades) cold-formed into H-shaped sections via automated manufacturing processes. Components (columns and roof beams) are precision-engineered for field bolting, eliminating welding and ensuring rapid assembly.
• Secondary Structural Systems:
  • Roof Purlins: C/Z-section members spanning perpendicularly across primary frames, supporting roof cladding while distributing live/dead loads.
  • Wall Girts: Horizontal members bridging columns to anchor wall cladding, enhancing lateral stability against wind/seismic forces.
• Bracing Systems: Integrated cross-braces, knee braces, and tie rods provide critical resistance to torsion and dynamic loads (e.g., 150+ km/h winds).

• Column-Free Large Span Design: Enables clear-span construction, eliminating the need for load-bearing walls or interior columns. The frame alone provides full structural support for unobstructed spaces up to 30-36 meters wide.
• High Customizability: Offers standardized warehouse plans (varying lengths, widths, and heights) alongside tailored solutions. Our design team creates custom blueprints to meet specific spatial requirements.
• Cost-Effectiveness: Prefabricated steel warehouses rank among the most economical building types. Factory-prepped components prevent on-site delays, while precision-engineered frames ensure rapid, seamless assembly.
• Rapid Construction: Prefab materials allow efficient cutting, shaping, and welding. All components ship to the construction site within weeks, drastically reducing project timelines.
• Minimal Maintenance: Steel resists rot, mold, and pests (e.g., termites). Hot-dip galvanized steel (Q235B/Q345 grades) prevents rust, with structures warranted for 25-50 years.

Lanjing Steel Structure Co., Ltd. is the professional manufacturer of Steel Structure Warehouse, Workshop, and Pre-engineered buildings. Our pre-engineered steel structure warehouse is built over a structural concept of primary members, secondary members, roof and wall sheeting connected to each other and various other building components.

These buildings can be provided with different structural and non-structural additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, fascias, canopies, crane systems, insulation etc., based on customer requirements.

Our steel structures serve a wide range of purposes, including:

• Warehouses, workshops, and factories
• Cold storage facilities and distribution centers
• High-rise buildings and shopping malls
• Power plants and industrial facilities
• Pedestrian bridges and aviation facilities
• Prefabricated public schools and sports arenas
• Agricultural buildings and storage sheds
• Commercial buildings and community centers
