Nowadays, there is an increasing number of steel structure plants due to the development of the industry. Why is the steel structure plant so preferable? Compared to the traditional wood or concrete structure plant, the steel structure is lighter, more cost-saving, durable, fast-constructed, and environmentally friendly. Thus, what is the cost of building a steel structure plant? What are the factors that decide the building cost? As a professional steel structure building manufacturer, we will show you 3 key factors that affect the cost of building a steel structure plant.
Steel sections and sheet materials are the main components of the steel structure plant. They decide about 70%-80% of the total cost of a steel structure plant. In particular, the price change of the raw materials has a great impact on the cost of building a steel structure plant. For example, the material and bearing surface of steel sections and the material and thickness of the enclosure plate can make the raw material price quite different.
A good design or planning is the essential solution to save the raw material of the steel structure plant. The design schemes of different steel structure plants are the main reason the quantity of raw material varies, which can directly affect the entire cost of the building.
The foundation cost of a steel structure plant has a close relationship with the local geology, and it is 15% of the total cost of the steel structure plant. Generally, the construction period of the foundation occupies about 25% of the entire construction period of the steel plant. During the planning, it is necessary to take the geological report of the plant location seriously. Choosing a reasonable foundation type and controlling the bearing surface and buried depth is beneficial for optimizing the total cost of building a steel structure plant.
The design of steel beams also affects the cost of a steel plant. Rectangular cross-section beams are the most common bending member, often used in planning, but their utilization rate is very low. On the one hand, the material stress near the neutral axis is relatively low. On the other hand, the bending moment of the beam varies along the length of the beam. Due to the low stress in most sections of the uniform cross-section beam, it is hard to make good use of the material. The material utilization rate can be improved only when the axial center is stressed.
Therefore, a plane truss can be used to replace a rectangular beam in the planning. The plane truss is equivalent to a hollowed-out beam, and the excess material in the beam is taken out, which helps save cost and reduce self-weight. What's more, it can also be developed into a space grid, and then the utilization rate of materials can be greatly improved.
The layout of the column grid is to determine the span and spacing of the columns. It will be more economical to choose a small-span portal steel frame if the technique requirements allow. Generally, the optimal spacing of portal steel frames is 6m-9m. When equipped with large-tonnage cranes, the economical column spacing is generally 7m-9m. It should not exceed 9m, or if it does, the quantity of steel used for roof purlins, crane beams, and wall frames will increase accordingly, which leads to a higher cost. Therefore, a reasonable column grid layout is important to lower the cost of steel structure plant building.
The construction time also affects the cost of building a steel structure plant. The installation technique is the key factor that decides the construction period. Building a steel structure plant is a systematic project that involves so many factors such as construction period, policy change, large engineering workload, etc. Thus, an efficient and professional installation team can help the builder save time and money.
