Q235 Q345 Q355 Steel Grade Galvanized or Painted Surface Steel Structure Workshop with 200 Km/h Wind Load Portal Frame Workshop

The ordinary light steel structure factory is a prefabricated industrial building designed for basic industrial production and material processing. Adopting a national-standard light portal frame steel system, it outperforms simple warehouses in equipment placement, mechanical vibration resistance, lighting and ventilation, and fire compliance. With standardized industrial design, factory prefabrication, and rapid on-site assembly, it delivers strong structural rigidity, light weight, and a flexible open interior space — a cost-effective industrial building solution for light industry and small processing enterprises.

A pre-engineered steel building is a modern construction method in which the complete design is finalized at the factory and the building components are delivered to the site and assembled there. All connections are bolted — no welding is required on site. An efficiently designed pre-engineered building can be up to 30% lighter than conventional steel buildings. Lighter weight means less steel and potential cost savings in the structural framework.

The main load-bearing frame adopts Q345B (S355JR) H-section steel columns and roof main beams. Wall girts and roof purlins use Q235B (S235JR) hot-dip galvanized Z/C section steel with good rust and deformation resistance. All main steel members adopt automatic submerged arc welding, sandblasting rust removal, and multi-layer anti-corrosion coating. Equipped with cross bracing, knee bracing, and tie rods, the complete bracing system guarantees high structural integrity and withstands continuous vibration from small production equipment.

The enclosure system can select A1-grade fireproof rock wool sandwich panels or color steel sheets with basic fire resistance, heat insulation, and dustproof performance. The roof uses a professional waterproof sealing system to prevent leakage. The floor can adopt ordinary concrete to support forklift traffic and small processing equipment.

• 1Light structure designed for small production equipment without crane load, meeting the vibration requirements of basic mechanical processing. Calculated in accordance with national standards for load, wind, and seismic resistance for stable long-term operation.
• 2Span ranges from 6–24 m, eave height 4–8 m. The column-free interior allows flexible production line layout and sufficient space for material handling.
• 3All steel components are factory prefabricated and bolt-assembled on site with a short construction period. Light weight reduces foundation cost and controls total investment.
• 4Side wall louvers and daylighting belts are optional to improve lighting and air circulation, reducing heat and dust accumulation.
• 5Enclosure panels comply with basic industrial fire codes with reserved pipeline positions for fire inspection approval.
• 6Customizable building dimensions. Partitions and auxiliary rooms can be added later for easy disassembly and reconstruction.

Small hardware workshops, food primary processing plants, packaging workshops, material sub-packaging workshops, small building material factories, and light industry assembly workshops. Suitable for basic continuous production of small and medium enterprises.

This light steel factory features light weight, fast construction, and open space. Different from pure storage buildings, it supports basic equipment load, seismic resistance, ventilation, and fire protection, providing economical and standardized factory solutions for SMEs.

As a professional steel structure solution provider, we deliver a full-cycle, one-stop service covering every phase from initial inquiry to final project completion, supporting your project with reliable efficiency and professional expertise.

We hold full engineering qualifications including the professional contracting qualification for steel structure engineering and the construction work safety permit, and have established three standardized management systems: ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System.

Our full product portfolio — steel structure buildings, modular light steel houses, and container houses — has all been tested and verified by authoritative third-party institutions. The scope covers UL certification, CE certification, Australian certification for rock wool, certifications for fiber cement boards and glass wool, as well as core performance indicators including structural mechanics, fire and corrosion resistance, thermal and acoustic insulation, waterproof sealing, and fatigue life, strictly complying with national building codes and industry standards.

For export products, we have obtained a full set of international certifications such as EU CE and EN 1090, which fully adapt to the engineering requirements and trade regulations of all regions worldwide, providing all-round guarantee for compliant project delivery and consistent quality.

Upon receiving your project requirements, our engineering team will provide feedback on drawing approval within 24 hours. We assign a dedicated specialist for 1-on-1 consultation to fully understand your project specifications, local construction codes, and budget expectations. Our team will tailor the structural design, optimize material usage, and propose the most cost-effective solution that perfectly fits your actual needs.

With standardized production management and a mature fabrication workflow in our own factory, we guarantee a 25-day fast delivery cycle for regular projects. To date, we have successfully delivered over 300 steel structure projects worldwide, accumulating rich experience in cross-border trade and overseas project implementation. All components go through strict quality inspection before delivery and are shipped together with complete construction drawings, detailed installation manuals, and guidance videos.

We provide 7×24 hours uninterrupted technical support throughout the whole project cycle. Whenever you encounter technical problems during installation or construction, our professional team will respond promptly and offer targeted solutions. We strictly implement safety management systems in both production and construction links, and have maintained a zero safety incident record all along, ensuring your project is carried out smoothly and safely.

Beyond fabrication and delivery, we also offer optional on-site installation guidance upon request to assist your on-site team with key construction procedures. From design, production, and logistics to after-sales support, we take charge of every detail, providing you with a truly hassle-free one-stop steel structure solution.
