Product Detail
Why Industrial Workshops Need Portal Frame Steel Structures
Industrial facility managers face a recurring dilemma: concrete workshops take too long to build, limit future reconfiguration, and require heavy foundations that drive up cost. The portal frame galvanized industry steel workshop directly addresses these pain points. With clear spans from 15 to 36 meters and eave heights up to 12 meters, the structure accommodates overhead cranes (5-32 tons), production lines, and heavy machinery without interior columns obstructing workflow. Q345B/Q355B welded H-section columns and rafters are fabricated to tolerance within ±2mm, ensuring bolted connections align perfectly on site. For a typical 2,000 m² workshop, the complete steel frame erects in 25-30 days-roughly one-third the time of reinforced concrete construction-delivering measurable savings in labor, financing, and opportunity cost.
Product Advantages
• Overhead crane ready: Columns and runway beams are pre-engineered for crane capacities from 5 to 32 tons, with fatigue-rated welded connections per GB 50017.
• Multi-span capability: Continuous portal frames support spans of 15-36m per bay, with expansion joints for buildings over 90m in length.
• Fire-resistant cladding: Rock wool sandwich panels (100-150mm, fire resistance ≥2 hours) available for walls and roofs to meet industrial fire codes.
• Acoustic and thermal insulation: Polyurethane-edge rock wool panels achieve thermal conductivity ≤0.040 W/m·K, reducing HVAC energy costs.
• Polyurethane sealant at panel joints prevents water infiltration and air leakage, maintaining interior climate integrity.
• Foundation flexibility: Bolted steel base plates adapt to independent, strip, or pile foundations depending on soil conditions.
Welding Qualification & Quality Controltrol
Our welding procedures are qualified to ISO 15614-1, and welders hold ISO 9606 certifications. Every primary load-bearing weld undergoes 100% ultrasonic testing (UT) per GB/T 11345, with radiographic testing (RT) on critical butt welds. CNC plasma cutting and automated submerged-arc welding (SAW) ensure dimensional precision at every stage. Surface preparation reaches Sa 2.5 (near-white metal blast) before epoxy zinc-rich primer (2×75μm) and topcoat application, delivering 20+ years of protection in industrial atmospheres.
