Which steel building category fits your project?
Selecting the Right Structural Framework
For wide clear spans and industrial operations with overhead cranes, Steel Factory Buildings (BH-IS-1001 to 1012) offer heavy portal frame construction up to 50 Ton crane capacity. For high-density urban or commercial sites, Structural Steel Buildings (BH-TSB-101 to 112) provide multi-story steel framing with composite deck concrete slabs. Residential and resort projects benefit from Duplex Steel Villas (60-day rapid build), Steel Cottage Houses (light-gauge weather-resistant vacation homes), and Steel Container Houses (modular 20ft & 40ft modified site offices or luxury units).
