Material selection for steel structure warehouse wall panels
In the construction of steel structure warehouses, the selection of wall panel materials is of utmost importance, as it directly affects the performance, cost, and service life of the warehouse.
At present, there is a wide variety of steel structure warehouse wall on the market, each with its unique advantages and disadvantages. Here you will see several common warehouse wall panels.
-
Corrugated Steel Sheet
Corrugated steel sheets are widely used as steel structure warehouse wall panels. It is mainly composed of a substrate, a coating, and a galvanized layer. The substrate is usually made of cold-rolled steel plate or hot-dip galvanized steel plate, providing basic strength and rigidity for the color steel plate.
​
The coating is with rich colors and good corrosion resistance, and the galvanized layer further enhances the anti-corrosion ability of the color steel plate.
The advantages of corrugated steel sheet is very significant. Firstly, they are easy to install due to their light weight and standardized size, the installation process is as simple as building blocks, which can greatly shorten the construction period and reduce labor and time costs.
​
Moreover, colored steel plates come in a variety of colors, with a smooth and flat surface, providing excellent decorative effects and meeting the exterior design needs of different buildings.
However, corrugated steel sheets are not perfect either. The service life of corrugated sheets is relatively short, usually around 10-15 years. Under long-term exposure to wind, sun, rain, and snow erosion, the surface coating is prone to peeling and rusting, which affects its performance and aesthetics. Regular maintenance and replacement are required, which undoubtedly increases the cost of later use.
There are mainly two types of corrugated sheets, that is corrugated stainless steel sheet and corrugated galvanised steel sheet.
​
Common width of the corrugated sheets are 430 mm, 470mm, 475mm, 750mm, 760mm, 780mm, 820mm, 840mm, 860mm, 900mm, 910mm, 920mm. Sometimes special width such as 1025mm or 1045mm is possible to meet the special needs of different projects.
​
General thickness of the corrugated steel sheet for warehouse wall panels is between 0.3mm-1.0mm, common thicknesses include 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, etc.
Special thickness such as 1.2 mm or even thicker may be used for some places with special requirements with high load-bearing capacity or fire resistance.
​
Length of the corrugated steel sheet generally between 1000mm-11800mm, popular ones include 1600mm, 1800mm, 2000mm, 2500mm, 3000mm, etc. The length can be customized according to the actual needs of the warehouse project.
In some large-scale construction projects, in order to reduce joint seams and improve the overall integrity and waterproof performance of the warehouse roof, ultra long single-layer corrugated roofing sheet with a length exceeding 10 meters will be used.
-
Sandwich panel
Sandwich panels have occupied a place in the steel structure warehouse wall panel material market due to their excellent comprehensive performance. It consists of two layers of metal panels and a core material in the middle, which are tightly bonded together through a special process to form a sturdy and stable structure.
There are various types of sandwich panels, including rock wool sandwich panels, glass wool sandwich panels, and polyurethane sandwich panels, each with unique performance characteristics.
-
Brick walls
Brick walls, as a traditional building material, also have certain applications in the selection of wall panels for steel structure warehouses. It is composed of bricks and mortar combined according to certain rules and masonry methods, with a long history and rich experience in use.
The advantages of brick walls lie in their excellent fire resistance, sound insulation, and durability. The main components of bricks are clay, shale, etc. These materials themselves have good fire resistance and can effectively prevent the spread of fires.
The dense structure of brick walls provides good noise insulation and can provide a quiet working environment for warehouses. Moreover, under normal use and maintenance conditions, brick walls have a longer service life and can withstand the test of time.
However, brick walls also have some obvious disadvantages. Firstly, it has a large self weight and requires a high basic bearing capacity for the warehouse, which increases the cost and difficulty of infrastructure construction.
Secondly, the construction speed of brick walls is slow, requiring a large amount of manpower and time, which is not conducive to rapid construction.
In addition, the insulation performance of brick walls is poor, and additional insulation measures are needed in the cold winter to maintain the temperature inside the warehouse, which also increases the cost of use.
Specification of Warehouse wall panels
-
Thickness
The thickness of steel structure warehouse wall panels is generally between 50mm and 200mm, and different thicknesses have different applicable scenarios. For some large steel structure warehouses, or warehouses located in high-altitude, windy and other harsh weather conditions, in order to ensure that the wall panels can withstand greater pressure and wind force, thicker wall panels such as 100mm, 120mm or even thicker panels are usually selected.
These thick walls have higher strength and stability, and can effectively resist various external forces, ensuring the safety and stability of the warehouse. For some small warehouses or internal partitions with low load-bearing requirements, thinner wall panels such as 50mm and 75mm may be a more suitable choice, which can meet basic usage needs, reduce costs, and alleviate structural burden.
-
Width
The width of steel structure warehouse wall panels is generally between 600mm and 1200mm, and can be customized according to specific design requirements.
The selection of width needs to consider the convenience of construction and the overall aesthetics of the building. A wider wall panel can reduce the number of joint seams, improve construction efficiency, and also make the wall look more flat and beautiful.
However, excessively wide wall panels may cause inconvenience during transportation and installation, increasing the difficulty of construction.
-
Length
In terms of length, wall panels are usually cut or customized according to the actual needs of the building. When determining the length of wall panels, it is necessary to comprehensively consider factors such as the height, structural form, transportation, and installation conditions of the building.
Generally speaking, in order to reduce waste and improve construction efficiency, it is advisable to choose wall panels of appropriate length and avoid excessive splicing and cutting.
At the same time, attention should be paid to the compatibility between the length of the wall panels and transportation and installation equipment such as cranes and forklifts to ensure smooth construction.
-
Peak height
The peak height is an important parameter of the steel structure warehouse wall panel, which refers to the height of the corrugated steel sheet on the wall surface. Different peak heights will have varying impacts on the performance and appearance of wall panels.
Generally speaking, the higher the wave peak, the better the drainage performance of the wall panel. This is because higher wave peaks can form larger drainage slopes, allowing rainwater to flow faster and reducing the possibility of water accumulation, thereby reducing the risk of wall leakage.
For areas with high rainfall or warehouses with high waterproof requirements, choosing wall panels with high wave peaks is a good choice. However, an increase in peak height can also bring some negative impacts.
On the one hand, the higher the peak, the higher the amount of material used, leading to an increase in costs. On the other hand, higher wave peaks will also increase the difficulty of construction, requiring higher construction techniques and technical requirements.
When selecting the peak height of the corrugated steel sheet for warehouse wall, it is necessary to comprehensively consider factors such as drainage performance, cost, and construction difficulty to make a suitable choice.
Technical Parameters of Warehouse wall panels
-
Bearing capacity
The bearing capacity is a key technical parameter of steel structure warehouse wall panels, which determines how much external force the wall panels can withstand without damage.
Bearing capacity refers to the ability of wall panels to maintain their structural integrity and stability under various loads.
Warehouses may face various loads such as wind, snow, earthquake, and pressure generated by stacking goods. These loads require wall panels to effectively withstand and disperse them to ensure the safety of the warehouse.
-
Stiffness
Stiffness is an important indicator for measuring the deformation resistance of steel structure warehouse wall panels, which reflects the ability of the wall panels to maintain their original shape under stress.
For wall panels, the greater the stiffness, the smaller the deformation under the same load, and the more stable the structure will be.
-
Weight
The weight of wall panels has a significant impact on the load-bearing capacity and construction of steel structures. If the weight of the wall panels is too large, it will increase the overall load of the steel structure and put forward higher requirements for the bearing capacity of the steel structure.
It may be necessary to use larger types of steel to support it, which not only increases the amount and cost of steel used, but also may affect the stability of the steel structure.
​
In some high-rise steel structure warehouses with high requirements for structural load-bearing capacity, the use of overweight wall panels may make the stress situation of the steel structure more complex, increasing the difficulty of structural design and construction.
​
However, lightweight wall panels are easier to transport and install, greatly improving construction efficiency and reducing construction costs.
-
Fire resistance
Fire resistance is a crucial technical parameter for steel structure warehouse wall panels, which directly affects the safety of the warehouse in the event of a fire and concerns the safety of personnel and property.
The indicators for measuring the fire resistance performance of wall panels mainly include fire resistance time and combustion rate. Fire resistance time refers to the period of time, usually in hours, during which a wall panel loses its supporting capacity, integrity, or insulation when it is subjected to fire.
The fire resistance time of wall panels with different materials and coatings varies greatly. For example, the fire rating of rock wool sandwich panels can reach Class A non combustible, with a fire resistance limit of up to 1-3 hours.
They can maintain structural integrity for a long time in a fire, providing valuable time for personnel evacuation and firefighting rescue.
The combustion rate refers to the mass or length of material loss per unit time during the combustion process of wall panels, which reflects the speed of wall panel combustion. The lower the burning rate, the slower the spread of the wall panel in the fire, which is more beneficial for controlling the development of the fire.
-
Sound insulation
The sound insulation performance is usually measured in dB (decibels), and the larger the value, the better the sound blocking effect of the wall panel.
The sound insulation performance of wall panels with different materials and thicknesses varies greatly. Wall panels made of materials with high density and dense structure have relatively good sound insulation performance.
For example, brick walls, due to their material density and large thickness, can effectively block the propagation of sound and have good sound insulation effects.
However, some lightweight wall panels, such as corrugated steel sheets, have relatively weak sound insulation performance if no special sound insulation measures are taken.
-
Heat insulation
The heat insulation performance plays a crucial role in maintaining temperature stability inside the warehouse and reducing energy consumption.
In warehouses in cold regions, good insulation performance can reduce heat loss and lower heating costs.
In warehouses located in hot regions, external heat transfer can be reduced, thereby lowering the energy consumption of air conditioning cooling.
