Depth analysis of steel frame formwork and aluminium frame formwork

With the vigorous development of the construction industry, as a key part of concrete pouring and molding, the selection of formwork is directly related to the quality, efficiency and cost of the project. Steel frame formwork and aluminium frame formwork are two types of formwork widely used in the construction field, each of which has unique performance characteristics and is suitable for different construction scenarios. Below, let's take a closer look at these two formwork systems to provide accurate selection references for construction practitioners in practical applications.

1. High strength and high stiffness: the steel frame formwork is made of steel, which can withstand large concrete pouring pressure and construction load, and is not easy to deform, so as to ensure the dimensional accuracy and surface flatness of concrete components, and is suitable for the construction of various large-scale and high-rise building structures;

2. Good durability: The steel has high corrosion resistance and wear resistance, and the steel frame formwork can still maintain good performance and long service life after many uses. Under normal circumstances, the steel frame formwork can be reused more than 200 times, which can greatly reduce the construction cost compared with the formwork of other materials;

3. Flexible assembly: The plate size of the steel frame formwork is relatively standard, which can be flexibly combined according to different construction needs, and is suitable for the construction of various structural forms, such as columns, beams, plates, walls, etc. At the same time, its connection mode is simple, the installation and disassembly efficiency is high, and the construction period can be shortened;

4. Smooth and smooth surface: The panel of the steel frame template is generally made of cold-rolled steel plate or stainless steel plate, with high surface flatness, smooth and easy to demould. This not only makes the surface quality of the concrete good, reduces the workload of subsequent plastering and other decoration processes, but also improves the appearance quality of the concrete, and makes the surface of the component smooth and beautiful;

5. Good environmental performance: the steel frame formwork can be recycled and reused, which meets the requirements of the national environmental protection policy. After the end of the project, the formwork can be recycled and re-smelted, which reduces the generation of construction waste and reduces the pollution to the environment.

1. Self-weight: the weight of the steel frame template is large, which brings certain difficulties to the handling, installation and disassembly in the construction process, and needs to be equipped with corresponding lifting equipment, which increases the construction cost and labor intensity;

2. Easy to rust: Although the steel itself has a certain corrosion resistance, the steel frame formwork is easy to rust in a humid environment or when exposed to alkaline substances in concrete for a long time. Rust will affect the surface quality and service life of the formwork, and regular anti-rust treatment is required, which increases maintenance costs and work;

3. Poor thermal insulation performance: The thermal conductivity of steel is large, and the thermal insulation performance of steel frame formwork is not as good as that of some wooden or plastic formwork. During winter construction, additional insulation measures are required to prevent the concrete from freezing, increasing the complexity and cost of construction;

4. High noise: In the process of installing and disassembling the steel frame formwork, due to the collision and friction between the steels, large noise will be generated, which will have a certain impact on the environment around the construction site and the lives of residents. In some areas with high requirements for noise control, corresponding noise reduction measures need to be taken.

Lianggong formwork has been rooted in the field of steel frame formwork for many years, and has continuously deepened and innovated the steel frame formwork by virtue of its persistent pursuit of quality and unremitting innovation in technology. For example, the Indonesian parking lot project under construction uses our steel frame formwork system, and the construction site of the Indonesian parking lot project is close to the existing building, and the construction party needs to accurately layout it in a limited space. The rapid assembly characteristics of our steel frame formwork have been fully utilized. The construction team quickly completed the construction of the formwork, which greatly shortened the construction period. In the large-area ground pouring operation, the high strength of our steel frame formwork ensures the flatness of concrete pouring and avoids the problem of uneven ground caused by formwork deformation. At the same time, its reusability also reduces the material cost of the project.

1. Light weight: the density of aluminum is relatively small, and the weight of aluminum frame formwork is light, generally about 20 - 25kg per square meter, which is convenient for manual handling and installation, reduces labor intensity, and improves construction efficiency, especially suitable for some construction parts where the space is narrow or the lifting equipment is inconvenient to reach;

2. High reuse rate: The aluminum alloy material has good corrosion resistance and strength, and the aluminum frame template can be reused more than 200 times under normal use and maintenance conditions, which greatly reduces the cost of using the template. At the same time, due to its long service life, the frequency of formwork replacement is reduced, which is conducive to ensuring the construction progress and quality;

3.High construction efficiency: the assembly and disassembly of the aluminum frame formwork are relatively simple, and the quick-release system is adopted, which can quickly complete the support and dismantling of the formwork. Moreover, the precision of the aluminum frame formwork is high, and the splicing is tight, which can effectively reduce the slurry leakage phenomenon in the concrete pouring process, improve the concrete surface quality, reduce the workload of the subsequent repair and decoration process, thereby shorten the whole construction period;

4. Good environmental performance: the aluminum frame template can be recycled and reused, after the end of the project, the template can be recycled and re-smelted into other aluminum products, with a high recovery rate, in line with the requirements of the national environmental protection policy, reducing the pollution to the environment;

5. Better thermal insulation performance: Compared with the steel frame formwork, the thermal conductivity of aluminum alloy is lower and has certain thermal insulation performance. In some buildings that do not have particularly high insulation requirements, the use of aluminum frame formwork can reduce the transfer of heat to a certain extent, which helps to reduce the energy consumption of the building.

1. Relatively small stiffness: Although the aluminum frame formwork has a certain strength, its stiffness is relatively small compared to the steel frame formwork. When bearing large concrete pouring pressure or construction load, deformation may occur, and reasonable reinforcement and support need to be carried out in the design and use process to ensure the dimensional accuracy and surface flatness of concrete components;

2. Not resistant to high temperature: the melting point of aluminum alloy is relatively low, when encountering high temperature environment, such as fire, etc., the performance of aluminum frame template will be greatly affected, and even deformation, melting and other phenomena may occur, affecting its use safety. Therefore, it is necessary to pay attention to fire prevention measures at the construction site to avoid the formwork being damaged by high temperature;

3. Easy to wear: The surface hardness of the aluminum frame formwork is relatively low, and it is easy to be worn during use, especially in the parts that are in contact with concrete. Wear will affect the surface finish and dimensional accuracy of the formwork, and reduce the molding quality of concrete, so it is necessary to regularly inspect and maintain the formwork, and repair or replace the parts with serious wear in time;

4. High requirements for later maintenance: In order to ensure the performance and service life of the aluminum frame formwork, regular maintenance and maintenance are required. Including cleaning the surface of the formwork, oiling and preventing rust, checking the fastening of the connecting parts, etc. If it is not properly maintained, it is easy to cause problems such as rust and deformation of the formwork, which will affect its use effect.

Because of its advantages of light weight and high construction efficiency, aluminum frame formwork is rapidly occupying the C position of building construction, and has received extensive attention from major construction units at home and abroad. With excellent product quality and excellent service, our company has emerged on the international stage, and its aluminum frame formwork has become the priority choice for many overseas projects, and the Singapore project is a very representative successful case. The scale of the project in Singapore is very large, and the requirements for construction quality and construction efficiency are extremely strict. From the early stage of the project, our company worked closely with the local construction team to gain an in-depth understanding of the project needs and tailor the aluminum frame formwork solution. Our aluminum frame formwork is highlighted by lightweight design, and the weight per unit area is significantly lower than that of similar products, which greatly reduces the difficulty of handling for construction personnel and improves construction efficiency. At the construction site, workers quickly complete the assembly with the help of the simple splicing system of the formwork, making the originally complex formwork construction work easy and efficient. During the whole project cycle, our company has set up a professional after-sales technical team to provide a full range of technical support for the construction party. From the on-site guidance of formwork installation to the timely solution of problems encountered in the construction process, it can achieve rapid response and efficient processing, which has won high praise from local partners.

All in all, steel frame formwork and aluminum frame formwork have their own advantages and disadvantages. When selecting the formwork, construction practitioners need to comprehensively consider the construction site conditions, building structure types, construction schedule requirements and cost budgets and other factors, so as to make the most suitable choice for the actual needs of the project, so as to achieve efficient construction and high-quality construction results.
