In modern prefabricated construction, light steel and heavy steel structures serve as two core solutions for industrial, commercial, and large‑span building demands. Understanding their definitions, features, and applicable scenarios helps global buyers select the most cost‑effective and reliable building systems. Below we clarify the key differences and highlight our factory’s professional advantages in manufacturing both types of steel structures.
Light steel structures mainly adopt portal frame systems, built with H‑beams for main frames and C/Z‑shaped purlins for secondary members. They feature low self‑weight, efficient steel usage, fast construction, and color‑coated steel cladding systems.
- Typical span: ≤18–24m
- Steel consumption: ≤50 kg/m²
- Components with smaller cross‑sections
- Equipped with cranes under 5 tons or no cranes
- Widely used in workshops, warehouses, 4S shops, exhibition halls, livestock barns, and small‑to‑mid‑size buildings
Refers to heavy-duty load-bearing steel structures characterized by heavy loads, large component cross-sections, thick steel plates, and high strength requirements.
- Features large component cross-sections and thick steel plates (typically ≥ 16 mm).
- Involves high steel consumption, generally exceeding 50 kg/m².
- Suitable for high-rise buildings, large-span structures, heavy-duty industrial plants, bridges, airport terminals, stadiums, and facilities requiring heavy-tonnage overhead cranes.
- Capable of supporting cranes with capacities of 10 tons, 20 tons, or even greater.
- Demands higher standards regarding processing precision, welding quality, and hoisting operations.
We use high‑grade structural steels Q355B (S355JR/A572 Gr.50) and Q235B (S235JR/A36), ensuring stable mechanical properties, high tensile strength, and strong toughness to meet diverse load and environmental demands.
We provide full‑chain customized services: structural design, detailed shop drawings, precision fabrication, installation guidance, and on‑site inspection, supporting non‑standard and project‑specific solutions based on client drawings and parameters.
We run mature parallel production lines for light and heavy steel structures, capable of mass manufacturing light portal frames, purlins, as well as heavy H‑beams and thick‑plate welded components. We handle projects from small warehouses to heavy‑duty plants and large‑span venues.
Equipped with CNC cutting, assembly, submerged arc welding, straightening, shot blasting and painting lines, we achieve millimeter‑level accuracy and full NDT for welds. Through professional design optimization, we balance economy and safety, cutting project costs without compromising structural performance.
We implement strict inspection from raw material incoming to finished product delivery, complying with international export standards. Our light steel solutions are economical and efficient; heavy steel products excel in load resistance, seismic performance and wind resistance.
We specialize in export packaging, maritime reinforcement, customs documentation, and compliance with various national technical standards. With rich experience in global steel structure projects, we provide reliable one‑stop solutions for clients worldwide.
Light steel structures offer cost efficiency and fast assembly for conventional buildings, while heavy steel structures provide robust strength for large‑span and heavy‑load scenarios. As a professional manufacturer, we integrate technical strength, production capacity and global service experience to deliver safe, reliable and economical steel structure solutions for global clients.
