Clear Span Metal Structures

Clear Span Metal Structures, also named column-free pre-engineered steel buildings (PEB), refer to metal framing systems with zero interior load-bearing columns. All roof and vertical loads are fully carried by exterior tapered H-section portal frames, delivering fully open, unobstructed interior space from wall to wall.

All structural members are precision fabricated in factory workshops: cutting, drilling, welding, shot blasting and anti-corrosion coating are completed off-site. Components are shipped as complete kits and assembled only with high-strength bolts on-site, no field heavy welding required.

Primary Clear Span Portal Frame: Tapered hot-rolled H-beam rafters & columns, optimized for wide spans up to 180m

Secondary Framing: Galvanized C/Z purlins, wall girts, cross bracing, tie rods and eave struts

Enclosure System: Galvalume metal sheets, EPS/rockwool/PU insulated sandwich panels, daylight panels, waterproof gutters & downpipes

Custom Attachments: Industrial overhead doors, ventilation fans, crane beams, steel mezzanines, canopies, skylights

Supporting Hardware: High-tensile bolts, anchor bolts, full foundation design drawings & calculation reports

Warehousing: Ideal for storing goods, machinery, and raw materials in various industries, such as manufacturing, logistics, and distribution.

Agriculture: Perfect for farm equipment storage, grain silos, and animal feed storage.

Commercial Storage: Suitable for small and medium-sized businesses that need secure and affordable storage spaces.

Workshop Facilities: A practical choice for businesses requiring workshops with ample space and durability.

1. Fully Open Column-Free Interior Space, Maximize Your Usable Area
Unlike concrete buildings limited to short spans with dense supporting columns, our clear span metal structures deliver wide, obstruction-free space from wall to wall. Spans up to 180 meters are available without inner posts, perfect for large machinery, overhead cranes, high rack storage, aircraft parking and livestock farming. You get over 95% usable floor space with no wasted zones blocked by pillars.
2. Save Huge Time & Cut Overall Construction Budget
All steel parts are prefabricated in our factory while your foundation works are underway simultaneously. The whole building only takes 2–3 months to finish, versus 6–9 months for concrete buildings.
Lightweight steel frames greatly reduce foundation load, so you spend less on piling, earthwork and concrete. Steel consumption is optimized to cut material cost, fewer field workers lower labor expenses. Total investment can be reduced by 30%–35%.
3. Factory Precision Fabrication, Stable & Reliable Long Service Life
Every component goes through automatic cutting, robotic welding, shot blasting and multi-layer anti-corrosion coating under strict ISO quality control. Uniform workmanship avoids common on-site defects of concrete structures such as cracks, leakage and uneven reinforcement.
The main steel frame adopts Q355B high-strength steel with complete anti-rust treatment, with a design service life of 50–70 years. It resists typhoons, heavy snow, earthquakes, coastal salt fog, mildew and termites.
4. Flexible to Expand, Relocate & Reuse with High Residual Value
The bolt-connected modular design allows easy side extension, height increase or additional lean-to without stopping your production. If you move your business later, the entire metal building can be fully disassembled, packed and reconstructed at a new site.
100% of steel materials are recyclable. When demolition is needed, the structure still retains high residual value, while concrete buildings only produce non-recyclable construction waste.
5. Ultra-Low Long-Term Maintenance Cost
Integrated metal roof and wall enclosure systems effectively prevent water seepage and wall peeling. There is no need for regular plaster repair, rust reinforcement or large-area renovation work as required by concrete buildings. Only simple routine cleaning is needed, saving decades of operation maintenance fees.
6. Eco-Friendly & Energy Efficient
Factory prefabrication generates minimal dust and construction waste. Insulated sandwich wall and roof panels greatly reduce cooling and heating energy consumption, helping you cut power bills year-round. The whole system meets LEED green building standards for global environmental compliance..
