Durable Steel Structures for Large-Scale Projects | Junyou Steel

Steel structure fabrication by Guangdong Junyou Steel Structure Co., Ltd is a precision-driven process that transforms raw steel into high-quality structural components—beams, columns, trusses, and custom parts—for construction projects. The company’s state-of-the-art fabrication facility, spanning 50,000m², is equipped with advanced machinery: CNC cutting machines (plasma, oxy-fuel) for precise shaping, robotic welding arms for consistent joint quality, and hydraulic presses for bending and forming. This technology ensures components meet strict dimensional tolerances (±1mm) and mechanical property standards. The fabrication workflow is systematic, starting with material selection—high-quality steel plates, sections, and tubes (certified to ASTM, EN, or GB standards)—inspected for chemical composition and mechanical properties. Next, cutting: CNC machines slice steel to exact lengths, with nesting software optimizing material usage to reduce waste (to <5%). Forming follows, with bending machines shaping steel into angles, channels, or curved sections, while drilling machines create precise holes for connections. Welding is a critical step, performed by certified welders (to AWS D1.1 or ISO 15614) using processes like MIG, TIG, or submerged arc welding. Welds are inspected via ultrasonic testing (UT) and magnetic particle inspection (MPI) to detect defects, ensuring strength and integrity. Post-welding, components undergo heat treatment to relieve residual stresses, followed by surface preparation (shot blasting to SA 2.5) and coating (primer + topcoat) for corrosion protection. Quality control is rigorous, with each component tagged with a unique identifier to track its journey from raw material to finished product. The company’s ISO 9001-certified quality management system ensures compliance with project specifications and international standards. Fabricated components serve diverse projects: industrial frames, bridge girders, stadium trusses, and high-rise columns, with the capacity to produce 10,000+ tons of steel structures monthly. Beyond manufacturing, the company offers value-added services: design assistance (DFMA—Design for Manufacturability and Assembly), 3D modeling of assemblies, and logistics coordination to deliver components on time. This comprehensive approach makes Guangdong Junyou Steel Structure Co., Ltd a trusted partner for steel structure fabrication, delivering quality, efficiency, and reliability.
