With the steel structure warehouse building, customers can choose from a variety of structures, ranging from simple two-bay warehouses to large industrial and commercial buildings. The steel frame of this prefab warehouse is unique in that it can be built within a short period of time without any trouble involved. Furthermore, this kind of storage center benefits from extremely low maintenance costs and can withstand even harsh weather conditions. Steel structure warehouse building is structural frames made of primary steel columns, beam, and secondary structure, which can be used as enclosures to accommodate electrical and plumbing facilities. One main concept of steel structure warehouse buildings is that they use a wide span, so a single bay space can be divided into multiple small rooms without having an outer column for support. That advantage will save the construction cost, which is especially suitable for large warehouses and huge factories since it takes up less land than traditional construction methods.
Advantages of Steel Structure Warehouse
01
Fast delivery
Compared with traditional concrete buildings, precast steel structures can save up to one-third of construction time. The all-steel fabric was cut, welded, drilled, and painted at the factory. It is easy to assemble quickly on-site and transport quickly. The longest transport time for container ships is four to five weeks.
02
Sturdy
We only use high-strength steel for design and manufacturing to ensure strong, durable and maintain structural integrity, beauty, and value for decades.
03
Wide internal space
The rigid steel frame is solid and can cover a larger area without internal support columns, which gives warehouse operations greater flexibility in storing and moving products quickly and efficiently.The clear span can be up to 60m without intermediate columns. The spacious interior space can improve the warehouse’s economic performance, and the owner can easily rent it to others.
04
Easy installation
Bolts can connect the steel structure warehouse, and it can be easily disassembled, transferred, and assembled easily without much expense, and it has strong mobility. This is especially important for exhibition projects that are used repeatedly. There is basically no possibility of movement in traditional wooden structures.

Single-story prefabricated Steel structure warehouse
Single-story prefabricated Steel structure warehouse is the most common type of warehouse. It comprises steel structure frames, wall panels, roof panels, doors, windows, etc. This type of warehouse is suitable for storage needs of all sizes and can be a simple storage shed or a large logistics warehouse.
Multi-story steel structure warehouse
The multi-story prefabricated Steel structure warehouse is extended from a single-story factory building, which can obtain multiple space areas under the same building. The multi-story steel structure factory building suits the high demand of many manufacturing industries to utilize space areas. In addition, the column area of the steel structure is small, which can reduce the use of the indoor regions and increase the usable space.
Cold storage steel warehouse building
Cold storage steel structure warehouse is a kind of warehouse specially used to store refrigerated or frozen goods. This warehouse type usually has refrigeration equipment, insulation materials, isolation doors, and other equipment to maintain a low temperature. The cold storage steel structure warehouse is suitable for storing cold fresh food, medicine, and other goods that must be kept at low temperatures.
Large-span steel structure warehouse
Large-span prefabricated Steel structure warehouse is a kind of giant warehouse that spans hundreds of meters or kilometers. This warehouse type usually uses long-span steel structure trusses, concrete foundations, etc., to support the load-bearing of large-area roofs. This warehouse type suits large-scale manufacturing enterprises, shipping ports, air logistics, etc.
The Structural Form of Steel Structure Warehouse
Portal steel frame structure
The portal rigid frame structure mainly comprises columns and beams; the rigid frame is a plane stress system. The bracing between the columns and the roof is set to ensure vertical stability.
Rigid frame
The columns and beams of the rigid frame are made of h-shaped steel, and various loads are transmitted to the foundation through the columns and beams.
Bracing and tie rod
The rigid bracing is made of hot-rolled section steel, generally angle steel. The flexible bracing is round steel. The tie rod is a compressed round steel pipe, which forms a closed force-bearing system with the support.
Roof purlins and wall girt
Generally, it is c-shaped steel and z-shaped steel. It takes the forces transmitted from the roof and wall panels and transmits them to the columns and beams.
Steel roof struss structure
Common structural forms of steel roof trusses: Triangle: Economically inefficient, generally used for small-span roofs. To accommodate pitch and shape, the pitch should be greater than or equal to 1/3, and the span should be less than or equal to 21m. Considering the arrangement of purlins, the truss joints are usually spaced 1.5m or 3m apart. The large pitch of the triangle makes the truss equivalent to a variable-section beam. Due to the rapid change in section (truss height), the stress on the chord members is unfavorable, resulting in smaller stress on the chord members in the center and greater stress on the chord members at the ends. Trapezoidal: The most commonly used form, often used as the roof structure of industrial buildings. The pitch is between 1/8 and 1/12, suitable for spans up to 36m. The stress distribution is more reasonable than the triangle’s, and the change in the section is relatively stable. Chevron-shaped roof truss: Parallel chord members are used at the top and bottom, connected in the middle, and the cross-section in the middle should be smaller than that of the trapezoidal roof truss to save material. The slope of one side of the roof is less than or equal to 1/10, suitable for spans greater than 30m. Three sections can be used when the span exceeds 42m, with a parallel section added in the middle. Corresponding supports should be provided at the fold points outside the plane.
The Difference Between Steel Structure Warehouse and Concrete Warehouse
Different construction period
In terms of the construction period, the steel structure has obvious advantages. The construction of the steel structure warehouse is very fast, because its construction is all produced in the factory on the construction site. It only needs to be hoisted and spliced to meet the urgent needs of some manufacturers.
Different environmental protection
The operation of the steel structure warehouse is as mentioned above. After being transported to the construction site, the components only need to be hoisted and spliced to complete the operation without water. There will be sand blowing and a large amount of dust, which can reduce environmental pollution and the impact on nearby residents. We Concrete buildings can't do that.
Different costs
Compared with concrete, steel structure saves construction cost and labor cost. The cost of building a steel structure warehouse is 20% to 30% lower than that of traditional concrete buildings, and steel structure is stronger and more durable than concrete.
Different structural weights
The steel structure warehouse itself has the characteristics of light weight. The walls and roof of the steel structure are made of light metal building materials, which are much lighter than the brick-concrete walls and terracotta roofs, which can reduce the overall weight of the warehouse. detrimental to the stability of the structure.
How to Prevent Water Leakage in Steel Structure Warehouse
The biggest fear of any building is a leaky roof. Warehouses are where goods are stored, and water leaks can cause substantial property losses. Therefore, water leakage prevention is one of the factors that must be considered.
Correct roof design
The warehouse roof should have a particular slope to prevent rainwater from accumulating and contribute to better drainage.
Install drainage system
Esign a reasonable drainage system for the warehouse, such as rain troughs, gutters, drainage pipes, etc., to prevent accumulation caused by excessive rain and insufficient drainage in time, guide water to flow down from drains and drainage pipes, and do not cause damage to roof panels and Damage to wall panels.
Choose high-quality waterproof materials
Choose high-quality waterproof materials for roofs and walls to ensure no water seepage.
Sealing seams and connections
Especially at the joints of roof components, necessary sealing must be carried out in advance to prevent roof leakage.
Regular maintenance and inspection
Inspect roofs, walls, etc., discover damage or potential leakage problems, and repair them promptly.
Details That Cannot Be Ignored in Steel Structure Warehouse Design
Anti-seepage
This is an essential requirement for buildings. To achieve the anti-seepage effect, it is necessary to use sealing washers at the screw openings and then fix them in a concealed manner. Use sealant or welding at the overlap of the color steel plates, if possible. Use full-body panels to minimize overlap and perform strict waterproofing at various joints. And it should be highlighted in the steel structure design drawings.
Wind pressure resistance
The windproof performance of the warehouse building is related to the fastening force and density of the fixed base. The designer must ensure that the metal roof panels will not be pulled off by negative wind pressure.
Sound insulation
Sound insulation may be one of many people’s concerns about steel structure buildings, but filling the wall layers with sturdy insulation materials can solve this problem. Of course, the sound insulation effect is related to the density and thickness of the sound insulation material, which can be selected as needed.
Ventilation
Vents should be installed on the roof to ensure indoor and outdoor air exchange.
Moisture-proof
Water vapor usually condenses on the bottom and inner layers of the roof, so the water vapor in the top must be drained away. The solution is to fill the wall layer with thermal insulation cotton, lay a waterproof membrane on the floor, and design ventilated nodes on the panel.
Load-bearing
At the beginning of the design, the steel structure warehouse must consider the construction load, rainwater, snow pressure, and maintenance load. Therefore, the load-bearing capacity of the panel, plate cross-section, strength and thickness of the material, force transmission method, and purlin spacing must be considered.
Lightning protection
No matter how high the building is, we must also consider preventing lightning from entering the room through the metal roof, especially metal-based steel buildings.
Insulation
The thermal insulation performance of steel structure factory buildings is closely related to the raw materials, density, and thickness of the insulation cotton. At the same time, the “cold bridge” phenomenon must be prevented.
Pay Attention To the Maintenance of Steel Structure Warehouse
After our steel structure warehouse is installed, for the owner, it is not allowed to change its structure without permission, not to remove any bolts and other components, and it is not allowed to increase or decrease the partition wall. If you need to change any parts, you must consult with the manufacturer. Next, it is up to the manufacturer to determine whether it can be changed. The steel structure must be maintained once with paint after being used for about 3 years, so as to give the building aesthetics and safety. The steel structure warehouse is connected with steel structure parts, so the electrical equipment, such as wires and the like, should be isolated by using wire grooves and pipes to avoid electric shock accidents.
The steel structure warehouse must be regularly cleaned and maintained. Under normal circumstances, inspection and maintenance are required once a year. When cleaning the outer wall of the steel structure warehouse, it is necessary to pay attention not to have any messy phenomena. Do not use steel balls, scrubbing brushes and other abrasive cleaning products. When using clean water, they should be washed from top to bottom. Branches, leaves and similar objects on the steel structure warehouse should be removed in time to avoid unnecessary trouble caused by the backlog. If the metal plate surface of the steel structure warehouse is damaged, it should be repaired in time to prevent the sun and rain from corroding the metal plate surface. If necessary, all high-elasticity nano-materials are used to protect the metal roof panel, and play an effective role in heat insulation and waterproofing, saving energy in indoor air conditioning. The maintenance and maintenance of the steel structure warehouse have a great relationship with the service life of the steel structure, so the industry mainly pays enough attention to it. If you encounter any problems during maintenance and maintenance, you should contact a professional steel structure manufacturer for help.
