Introduction: Steel raised floors were the first kind to be created and are popular used. Although aluminum raised flooring has not been created for as long time as steel raised flooring, it now has a large market due to its good performance and ability to meet the special requirements of high-quality projects. This article analyzes and compares the advantages and disadvantages of steel raised floors and aluminum raised floors to help customers choose a more suitable floor based on some factors that customers will be concerned about.
In the 1950s, computer technology matured, people needed to treat a lot of cables in office buildings,computer rooms or data centers. A company in the United States created this kind of raised floors. It uses underfloor structure to support the raised loor panels, and there is enough space under the floor to organize cables. This is where raised floors strated. in coming time, after continuous improvement, it developed to nowdays raised floors. The upper layer of the raised floor system is a square floor, and brackets and beams are used under the floor to form a supporting system. Each piece of the square floor can be moved and replaced individually, making it easy to open the floor and treat the cables below. Raised floors mainly include steel cement raised floors, calcium sulphate raised floor, woodcore raised floor, FRC raised floor, aluminum raised floor,glass raised floor.
Steel was firstly used for raised floors and is currently the most widely used product. steel raised floor are fabricated with steel sheet (SPCC) welded to a formed steel bottom pan (ST14), filled internally with a light weight cement material which is totally encased with in the steel welded shell. The steel shell is protected from corrosion by applying epoxy paint. if it not covering any material, we call it OA bare raised floor, usually size 600x600mm, or 500x500mm, called OA60 or OA50.
In fact, aluminum raised flooring is also a type of raised floor, but its main material is aluminum alloy. use die-cast aluminum ADC12 make to 600x600mm floors, also can cover with antistatic HPL or PVC finishes materials. also can use toghtner with supports system. there are perforated aluminum raised floors and aluminum grate panels.
In terms of the properties of the material itself, steel is harder than aluminum, but aluminum has better ductility and flexibility than steel. The load-bearing capacity of the raised floor can be changed by changing the thickness of the material. Therefore, in theory, steel raised floors and aluminum raised floors can have the same load-bearing capacity. But if economic costs are considered, steel raised floors are cheaper.
One of the biggest differences between the two kind raised floors is the weight of the material. Steel has a much higher density than aluminum, so the wieght of steel is much higher. Mild steel is lighter than carbon steel, but aluminum is much lighter anyway. On that, aluminum raised floors has a light weight and good load capacity at same time, which is very good material. Steel raised floor combine with steel sheet case and cement in core, so it has a higher weight.
Aluminum is a good conductor of electricity and is known for its good conductive properties. Because of its lightweight and ability to resist corrosion, it is commonly used in high voltage overhead power lines, automotive radiators and air conditioning units. Therefore, aluminum floors are often used in electronic component workshops, laboratories, aerospace centers, data centers, etc. Raised flooring can also optimize the electrical conductivity of the floor by using conductive veneer materials and conductive accessories.
Aluminum has good thermal conductivity and is therefore often used as a heat sink for computers and cooling systems in vehicles. Stainless steel does not conduct heat well. However, it has a higher melting point than aluminum and can be used over a wider temperature range. In large data centers, aluminum grille floors are often used for ventilation and cooling systems. Aluminum raised floors and steel rasied floors are often used together. In projects where steel raised floors are used in large areas, aluminum air flow panels are also used to achieve better heat dissipation.
Aluminum is highly oxidizing, and the passivation layer formed on its surface due to oxidation makes it highly corrosion-resistant. Corroded surfaces are more likely to breed bacteria than smooth surfaces, so aluminum floors are very good at resisting corrosion and bacteria. Aluminum floors are widely used in clean rooms, sterile rooms, laboratories and other environments. Stainless steel is made up of elements such as iron and chromium, an additive that helps resist corrosion, whereas regular steel corrodes very easily. Therefore, steel needs to be painted or powder coated to prevent rust and corrosion. MAJET's steel floor uses high-quality plastic powder to spray the entire steel floor, which is not easy to fall off. It can ensure long-term protection of steel materials, effectively prevent rust and corrosion, and effectively extend the service life of the steel floor.
To sum up, the performance difference between steel flooring and aluminum flooring is still very big. It is difficult to simply say which flooring is better. It mainly needs to be combined with the requirements of the place where it is used to make a better judgment.
Because the aluminum material itself is much more expensive than steel. It is natural to imagine that the price of aluminum flooring is much higher than that of steel flooring. On the other hand, the steel raised floor has cement poured into the steel shell as filler, while the aluminum raised floor is made entirely of die-cast aluminum. From this aspect, the steel rasied floor also saves costs.
Two different materials by themselves will not increase installation costs. In the case of conventional brackets, there is no need to compare their installation costs. but, Special circumstances require additional consideration.
If the floor is used in an environment with relatively high humidity and prone to corrosion, the service life of the aluminum floor will be longer than that of the steel floor, and the maintenance cost will be lower. MAJET's raised floors have always maintained a high quality level and can be used for a long time.
Although steel floors are theoretically much heavier than aluminum floors, aluminum floors are thicker and account for a larger volume. The difference in total quantity also affects the choice of transportation plan. For example, a 20GP container can usually load more than 500 square meters of ordinary steel raised floors and more than 300 square meters of aluminum rasied floors. But when the number of aluminum raised floors is relatively large, you can also choose to use 40GP container to load them. So it's hard to say which one has lower shipping costs. This requires analysis and calculation based on the actual situation.
The options we discuss here are only suggestions for choosing the most cost-effective and economical option. If you do not consider cost and budget, and just need to choose the best material, you can consult MAJET Company additionally.
1.Steel rasied flooring can be applied to almost all commercial buildings, especially OA bare panels, because the surface is bare. After installation, customers can use any material they like as the surface material. Low cost, good load-bearing capacity, and long service life is you can get.
2.Aluminum rasied flooring can actually be applied to most places, but due to its high cost, we recommend that customers who have high requirements for conductivity, corrosion resistance,and cleanliness to choose aluminum rasied flooring.
3.There is also a situation where steel rasied floors and aluminum air flow panels can be used together, especially in large data center projects with many cabinets. The aluminum grille plate is resistant to high temperatures and has good load-bearing ability at same time. It can be used together with the cold air system to play a good role in cooling and ventilation.
No matter which type of flooring is used, it has own advantages and disadvantages. The choice of raised floor solution is a more professional and complex task, which requires the engineering party and the manufacturer to consider it together.
