Large span space of portal steel frame hot-rolled H-shaped steel structure

Product Specification

Large span space of portal steel frame hot-rolled H-shaped steel structure warehouse building

Steel structure warehouse is a modern storage building with steel as the core load-bearing structure (including steel columns, steel beams, steel truss, etc.), which has the significant characteristics of fast construction, high space utilization and excellent seismic performance. It is widely used in industrial raw material storage, logistics transfer,-commerce warehousing and other scenarios. The main frame adopts standardized steel such as H-shaped steel and C-shaped steel, and the roof and wall surface commonly use color sandwich panels. Some large-span warehouses will be matched with steel trusses or grid structures to reduce the number of columns and release the internal space. Steel components are prefricated in the factory, and only need to be assembled on site, the construction period is usually 30%-50% shorter than concrete warehouses; without too many-bearing columns, it can achieve a large span design of more than 30 meters, which is convenient for forklifts, shelves and other warehousing equipment to operate; after anti-corrosion treatment (such as galvanizing, spraying), the service life of steel can reach 20-30 years; according to demand, it can be equipped with loading and unloading platforms, lifting beams, ventilation systems and fire fighting facilities to meet the storage needs of different types of goods

​Product Description:

Steel has the core mechanical properties of "high strength - low density". Under the same load-bearing conditions, the cross-sectional size steel members (such as H-shaped steel, steel truss) is much smaller than that of concrete members, and the self-weight is lighter. This attribute makes it easy achieve a column-free large-span design of over 30 meters for steel structure warehouses, completely eliminating the dense load-bearing columns in traditional warehouses from dividing the. It can not only meet the needs of multi-layer arrangement of heavy-duty racks and free maneuvering of large forklifts, but also flexibly divide the storage area sorting area and other functional modules, and the space utilization rate is 20%-30% higher than that of concrete warehouses. It is especially suitable for large-volume scenarios such as e-commerce and industrial raw materials.

Steel has good weldability and cuttability, and all components such as steel columns, steel beams, and purlins can be precisely prefricated in the factory according to standardized drawings. On site, only bolted connections or welding assembly are required, without waiting for pouring and curing like concrete construction. This " prefabrication on-site assembly" model directly compresses the construction period of steel structure warehouses to 50%-60% of traditional warehouses, and quickly meet the storage needs of enterprises for "build and use immediately", reducing time costs.

Steel is a kind of elastic-plastic material, which has excellent impact toughness and ductility. Under the action of external forces such as and strong winds, it can absorb energy through its own deformation and is not prone to brittle failure. At the same time, the overall stiffness of the steel structure frame is good and the node connection is reliable, which can effectively transfer the load and avoid the overall collapse of the building. Compared with the concrete structure with strong brittleness, the steel warehouse has a higher safety margin in the seismic fortification area of 6-8 degrees, and can better protect the stored goods (especially precision instruments and high-value industrial components from natural disasters and reduce the risk of property loss.

Why Choose Us

Professional team: We have a professional design team composed of senior structural engineers, architectural designers, etc. They have solid professional knowledge and rich practical experience, and can deeply understand the diverse needs of customers, whether it is a conventional industrial plant or a unique commercial building, they can accurately grasp the key points of design. In the early stages of the design process, the team will fully communicate with the client to understand the functional positioning, spatial layout requirements, budget constraints and expected service life of the project in detail, so as to lay a solid foundation for the subsequent design work.

Process quality control: In the process of steel structure processing and production, multiple quality control points are set up. For example, real-time monitoring of key processes such as cutting, drilling, and welding of steel is carried out, and operations are carried out in strict accordance with process standards. Non-destructive testing technology, such as ultrasonic flaw detection, magnetic particle flaw detection, etc., is used to inspect the quality of welded joints to ensure that the welding quality meets the requirements of the design grade. Each completed process, the quality inspection is carried out, and only after passing can the next process be entered to avoid the flow of unqualified products into the next link.

Transportation plan planning: according to the size, weight, quantity of the steel structure, the geographical location of the project site, traffic conditions and other factors, formulate a reasonable transportation plan. Choose the right transport vehicles, such as flatbed trucks, low-bed semi-trailers, etc., to ensure that the goods can be loaded and transported safely and stably.

Choosing our steel structure storage products is to choose professionalism, quality, efficiency and value. We look forward to working with you to create exceptional construction projects.
