Qingdao Xinguangzheng Steel Structure Co., Ltd is an enterprise specializing in the production of steel structure workshop, warehouse steel structure, bridges, exhibition hall, showroom, animal husbandry farm and equipment and prefabricated house. She has 24 years of experience and has obtained CE, ISO, BV, SGS and TUV certifications. Engineered for maximum spatial efficiency, our clear span large warehouse steel structure construction eliminates the need for internal support columns, providing an expansive, uninterrupted interior footprint. This structural advantage is critical for industrial manufacturing, large-scale agricultural storage, and heavy equipment maneuvering, allowing for unrestricted layout configurations. The heavy-duty steel components feature a thick, visually solid galvanized finish that feels cold and rigid to the touch, ensuring long-term structural integrity against harsh environmental factors.
To ensure absolute precision in structural engineering and accurate cost estimation, we require specific environmental and dimensional parameters. The physical weight of the snow, the lateral force of local winds, and potential seismic activity directly dictate the thickness, grade, and welding specifications of the portal frames. By providing the exact details below, our engineering team will calculate the exact stress tolerances required to keep your facility secure and compliant with regional building codes.

Founded in 1997 specializing in the design, production and construction of steel structure for agricultural, industrial, commercial and residential applications. Our extensive history is backed by a modernized manufacturing facility and a stringent QA/QC inspection system. Every piece of raw material is fully traceable, and our high-frequency welding processes are continuously monitored to guarantee that every beam and column leaving our factory meets strict international tolerances.
The design can be matched most common needs, from covering a large area for production workshop and warehouse, to small detached structures. The clear span architecture maximizes internal volumetric capacity, making it exceptionally adaptable for heavy machinery parking, bulk grain storage, or complex assembly lines where internal pillars would otherwise obstruct operations.
Making design according to the standard loads, to suit most situations. It is the ideal solution for permanent, flexible structures, responding to geographical restrictions in terms of snow loads, wind loads and earthquakes. Top quality materials used ensure excellent resistance over time, appreciated long-term. We strictly adhere to local compliance regulations, ensuring the structural blueprint matches the exact environmental stressors of your specific geographic location.
Their solid, hot-dip galvanized and painted steelwork make it long-lasting and weatherproof. The thick zinc coating provides a distinct, slightly textured metallic finish that acts as a physical barrier against moisture and oxidation, preventing rust even in highly corrosive coastal or heavy-industrial atmospheres.
Design warranty are covered by a 50-year on the steel structure. Quality management system is certified ISO 9001. This long-term commitment reflects our confidence in the precision engineering and material density of our structural components, providing peace of mind for heavy-duty commercial investments.
Steel structures comply with the Technical Construction Standards, providing important innovations in the seismic design field. Structural weights are much smaller in steel constructions than in traditional ones, with a consequent reduction in seismic forces on structures and an increased seismic action dissipation capacity. The inherent ductility of the steel allows the frame to flex and absorb kinetic energy during tremors without fracturing.
Walls and roofs are made of sandwich panels, consisting of two layers alu-zinc sheet layers filled with an inner core of polyurethane foam (PUR)/EPS/Rockwool/Glasswool. These dense insulating cores dramatically reduce thermal transfer, maintaining stable interior temperatures while dampening the harsh acoustic reverberations typically associated with heavy rainfall or industrial machinery.
It is easily self-installed by skilled technical workers using appropriate installation equipment. All kit components have associated codes, used in the installation manual for quick, easy identification. Every bolt hole is precision-punched in the factory, ensuring that the heavy steel beams align perfectly on-site without the need for forced adjustments or field welding.
One of the major advantages is reduced manufacturing time, materials being ready for shipping within 4-6 weeks from your order confirmation. This accelerated timeline is achieved through our automated production lines, which cut, weld, and coat the steel with relentless efficiency.
Our global project cases span multiple continents, proving the adaptability of our structures in extreme climates—from arid deserts to heavy-snow mountainous regions. We manage complex logistics to ensure the heavy structural steel reaches your location safely.
Supply the relevant installation manual and most documents likes architectural drawings, container loading list, certificates of origin, packing lists, etc. This comprehensive paperwork eliminates customs delays and provides your on-site contractors with the exact technical blueprints needed for immediate assembly.
If you can not find the solution that best suits your needs, our engineers will design a tailor-made one for you. We provide 100% customized solutions regarding dimensions, door and window placements, and specialized ventilation systems to match your operational workflow.
We utilize specialized steel pallets to secure the heavy portal frames and delicate cladding materials. This prevents the abrasive friction of metal-on-metal contact during ocean transit, ensuring that the protective painted and galvanized coatings arrive completely intact and free of scratches.

First, We provide full set of shop drawing before installation. This includes detailed foundation layouts and anchor bolt placement diagrams, ensuring the concrete base is perfectly prepared to receive the heavy portal frames.
Second, Your engineer and workers can go to our company to learn the installation. We offer hands-on guidance with our structural components, teaching your team how to identify parts via our coding system and properly torque the high-strength bolts.
Third, We can send our engineer and worker to help the installation at site. For complex or large-scale clear span projects, having our technical experts on the ground guarantees that the framing, purlins, and insulated cladding are assembled safely and strictly according to the structural blueprints.
To protect the structural integrity and surface finish of every component, we utilize heavy-duty steel pallets for packing. The galvanized purlins, portal frames, and color-coated steel sheets are tightly strapped and wrapped to prevent moisture ingress and physical shifting during transit. This systematic packaging not only safeguards the materials but also simplifies the unloading process when the shipping containers arrive at your site.
We offer flexible financial arrangements to accommodate international procurement requirements. Our standard payment terms are T/T (Telegraphic Transfer) and L/C (Letter of Credit), ensuring secure and transparent transactions for heavy industrial investments.
Every steel component undergoes rigorous surface treatment, including hot-dip galvanization or industrial-grade painting. Furthermore, the materials are packed on steel pallets and securely sealed to block out corrosive salt air and moisture during the 30-45 days of ocean delivery.
