Factors affecting the cost of steel structure plant

Steel structure plant is destined to have a strong construction market share because of its beautiful appearance, short construction period, high degree of industrialization, resource reuse and other advantages. The cost of steel structure plant is also a concern of many people. It is the focus of many steel structure enterprises to not only control the cost of steel structure plant but also give play to the technical advantages of steel structure plant.

The factors affecting the cost of steel structure plant mainly include the following aspects:

1.The raw materials

Hot rolled steel and steel plates are the main frame of steel structure plant, accounting for about 70%-80% of the total cost. The fluctuation of raw material market price of steel structure directly affects the cost of steel structure workshop. The steel materials standard, section, thickness, and the unit price are all very different which influence the total price. And whether the steel structure workshop should have a skylight, workshop space, span are also important; Many other factors such as crane, crane tonnage and working grade are important factors affecting the cost of steel structure plant.

2. The design factor

Reasonable design is the most important thing to save raw materials and control the cost of steel structure plant. It will directly affect the raw material quantity and total cost of steel structure workshop.

• Foundation design: The foundation cost is closely related to the geology of the plant. The foundation construction period accounts for about 25% of the total construction period of the plant, and the cost is 15% of the total cost of the steel structure plant. It is also necessary to pay attention to the geological report of the location of the plant, select a reasonable foundation type, control the load surface and buried depth of the foundation to the total cost of steel structure plant played a positive role

• Steel beam design: Due to different project design requirements, it can choose H steel, steel truss and space frame design. Based on different performance, the price will be totally different.

• Column design: column layout is to determine the span and spacing of the column. Under the condition of technological requirements, it is more economical to choose the small-span portal rigid frame as far as possible. In the construction process, try not to waste materials, to avoid increasing the cost of steel structure plant, the installation of column mesh, steel beam must be reasonable, to ensure that there will be no quality problems, improve the installation quality of the plant, reduce costs.

3. The construction and installation factors

The length of the construction period is also a part of the cost of the steel structure plant, the installation technology is skilled or not is the main reason for the length of the construction period. Construction of structural plant is a system project, involving a wide range of factors, the construction cycle, policy changes, the volume of work, etc. can affect the cost of steel plant.
