Introduction to Steel Structure Products of Qingdao Xinguangzheng Steel Structure Co., Ltd.

With over 20 years of dedication to intelligent steel structure manufacturing, Qingdao Xinguangzheng Steel Structure Co., Ltd. (Stock Code: 834422) has built a full-category, multi-specification, high-standard and internationalized steel structure product system. Supported by an intelligent manufacturing base with an annual output of 150,000 tons, dual first-class core qualifications and a comprehensive international certification system, the company is capable of manufacturing a full range of products including light steel, heavy steel, long-span trusses, high-rise and super-high-rise steel structures, bridge steel structures, special-shaped spatial structures and equipment supporting steel structures. Equipped with complete enclosure systems and integrated building products, it delivers customized solutions for industrial buildings, public venues, municipal roads and bridges, new energy supporting facilities, overseas projects and other diverse scenarios. Xinguangzheng is one of the few domestic professional suppliers that integrates steel structure R&D and design, intelligent manufacturing, precision processing and customized export services.

As one of the company’s flagship standardized products, the light steel structure series includes hot-rolled and high-frequency welded H-beams, C-beams, Z-beams and thin-walled steel profiles. It is widely applied in small and medium-sized industrial workshops, warehouses, exhibition venues, agricultural and animal husbandry buildings, prefabricated auxiliary buildings and other facilities. Featuring light self-weight, flexible span design, convenient installation and cost efficiency, these products achieve a high factory prefabrication rate and greatly shorten on-site construction cycles. All components are processed by high-precision CNC equipment with uniform and smooth welding seams and strictly controlled dimensional errors within premium industry standards. With professional rust removal, anti-corrosion and spray coating treatments, the products deliver excellent wind resistance, seismic performance and corrosion resistance. Compliant with Chinese national standards, they can also be customized in accordance with American, European, Russian and other international standards for various overseas small and medium-sized steel structure projects.

The heavy steel structure series represents the company’s high-end core products, covering welded box columns, welded H-beams, cross-shaped steel columns, large steel beams and thick-plate load-bearing components. These products are mainly used for heavy-load scenarios such as heavy-duty industrial workshops, large logistics warehouses and multi-story industrial buildings. Equipped with automatic box beam production lines, integrated assembling-welding-straightening equipment and intelligent thick-plate cutting machines, the company can manufacture large-section, thick-plate and high-load-bearing steel components to solve the load limitations of traditional light steel structures in heavy-duty, high-rise and long-span projects. Boasting high overall rigidity, strong bearing capacity and superior structural stability, the products strictly comply with national and international engineering standards, adapting to complex working conditions with high loads, high seismic intensity and strong wind pressure. They are the preferred structural solution for large-scale industrial infrastructure projects.

The company has mature technologies in the processing and intelligent manufacturing of long-span spatial structures, providing customized pipe trusses, steel grid structures, special-shaped spatial trusses and large-span roof load-bearing trusses for public buildings such as stadiums, exhibition centers, exhibition halls, high-speed railway stations, terminals, large canopies and landscape venues. Supported by independently developed sliding construction technology and prefabricated integrated structural technology for long-span spatial systems, the products feature large span, light weight, flexible spatial modeling and minimalist aesthetics, enabling column-free large-space layouts that perfectly meet the functional and aesthetic requirements of large public buildings. All truss components adopt precision CNC pipe cutting and automatic robot welding, ensuring high node accuracy, excellent overall integrity and structural safety factors far exceeding conventional industry standards.

Tailored for high-end architectural scenarios including urban high-rise buildings, commercial office buildings, multi-story complexes and industrial office buildings, the company develops and manufactures prefabricated steel components for high-rise and super-high-rise buildings, such as high-rise steel frame columns, frame beams, core tube steel structures and assembled composite steel structures. Leveraging core R&D achievements including BIM 3D modeling optimization and post-earthquake replaceable prefabricated integration technology, the products offer outstanding seismic performance, rapid construction speed, low carbon emissions and high prefabrication levels. They effectively resolve common pain points of high-rise construction such as long construction cycles, massive on-site operations and high environmental pressure, fully meeting the construction standards of modern urban high-end buildings.

The company possesses professional manufacturing capabilities for bridge steel structures, custom-producing highway steel box girders, steel truss bridges, municipal pedestrian overpasses, bridge load-bearing components and anti-collision steel structures. Manufactured in strict accordance with high-standard road and bridge engineering specifications, the products adopt precision thick-plate processing, non-destructive flaw detection and multi-layer anti-corrosion treatments, featuring excellent fatigue resistance, impact resistance and weather resistance. Adaptable to harsh outdoor environments with alternating high and low temperatures, rain, snow and corrosion, they are widely used in urban municipal renovation, highway bridges, landscape bridges and traffic supporting projects.

Based on rich practical experience in offshore photovoltaic and new energy infrastructure projects, the company develops customized steel structures for new energy facilities, large equipment support frames, industrial equipment bases, mechanical matching steel structures and photovoltaic bracket supporting structures. Adopting exclusive anti-corrosion processes and cold-bridge prevention connection technologies, these products are highly resistant to corrosion, aging and strong winds, perfectly adapting to harsh offshore environments with high salt fog and strong erosion. They have been successfully applied in national key new energy projects including million-kilowatt offshore photovoltaic programs, serving professional scenarios such as new energy construction and heavy equipment supporting facilities.

In addition to main steel structure components, the company provides a full range of building enclosure products, forming an integrated system of main steel structure + supporting enclosure systems. The product lineup includes profiled steel sheets, rock wool sandwich panels, EPS thermal insulation composite panels, roof daylighting panels, waterproof and thermal insulation boards, steel structure hardware accessories, sealing parts and edge trimming systems. All enclosure products are precisely matched with main steel structures, integrating thermal insulation, heat insulation, waterproofing, fire prevention, wind resistance and noise reduction functions. They satisfy thermal and fire protection requirements for industrial, public, cold storage and logistics buildings, enabling integrated project delivery and significantly improving the overall integrity and service life of engineering projects.

Deeply engaged in the prefabricated construction industry, the company provides standardized light steel villas, modular integrated houses, container office buildings, temporary construction rooms and prefabricated supporting buildings. Fully prefabricated in factories and assembled modularly on-site, these products feature rapid installation, environmental friendliness, reusability and convenient relocation. They are widely used in rural construction, scenic area supporting facilities, construction site temporary accommodation, emergency buildings and office supporting facilities, complying with national policies for green buildings and prefabricated construction development.
