Multi storey steel buildings from Guangdong Junyou Steel Structure Co., Ltd redefine vertical construction, offering efficient space utilization combined with structural agility to meet the demands of urban and commercial development. These buildings leverage steel’s exceptional strength-to-weight ratio to support 5-30 storeys, with each floor capable of bearing live loads up to 5kN/m² (suitable for offices, apartments, or light industrial use). The steel frame—composed of columns (H-beams, 200-400mm in flange width) and beams (I-beams, 150-300mm in depth)—transfers loads efficiently to the foundation, reducing material usage by 25% compared to reinforced concrete structures. Construction efficiency is a standout feature. Prefabricated steel components—including floor cassettes, wall panels, and staircases—are manufactured off-site, allowing for concurrent fabrication and site preparation. This parallel process cuts construction time by 40%: a 10-storey building can be completed in 8-12 months, compared to 18-24 months for concrete equivalents. On-site assembly uses bolted connections, minimizing noise and debris, making them suitable for urban areas with strict construction constraints. Design flexibility caters to diverse uses. For commercial towers, open floor plans (up to 1,000m² per floor) accommodate customizable office layouts, while integrated service cores house elevators, stairs, and utilities. Residential buildings feature modular bathroom pods and pre-installed plumbing/electrical systems, reducing on-site finishing time. Acoustic insulation (rock wool with 45dB sound reduction) and thermal insulation (polyurethane panels with U-value 0.18 W/m²K) ensure comfort, while large window openings (frameless or curtain wall systems) enhance natural lighting. Safety and sustainability are prioritized. The steel frame’s ductility provides superior seismic performance, withstanding lateral displacements of 2.5% of building height during earthquakes. Fire protection—intumescent coatings or encased concrete—achieves 2-4 hour fire resistance ratings. Steel’s recyclability (90% of components are recyclable) aligns with green building standards like LEED and BREEAM, while rainwater harvesting and solar panel integration further reduce environmental impact. Whether for mixed-use developments, corporate headquarters, or high-rise residences, these multi storey steel buildings balance performance, efficiency, and adaptability.
