Heavy Steel Factory Buildings & Large-span Public Buildings

Heavy steel workshops and large-span public buildings represent the third major category within the LESEN GROUP product portfolio, classified as permanent structures with a design life exceeding 50 years. These buildings utilize heavy steel structural systems as the primary load-bearing framework, composed of H-beam columns and beams, box columns, lattice columns, and pipe trusses, enabling single spans of up to 42 meters or even 85 meters—creating vast column-free interior spaces with exceptional spatial efficiency.

These structures are widely applied in industrial workshops, warehouses, sports stadiums, exhibition centers, airport terminals, high-speed railway stations, and other large-scale public facilities, as well as high-strength industrial buildings in mining and energy sectors. LESEN GROUP operates dedicated heavy steel processing workshops (Workshops 5-6) equipped with laser cutters, submerged arc welding equipment, and specialized machinery, offering complete in-house capabilities from thick steel plate cutting and welding to surface anti-corrosion treatment.
