One of the most common questions from clients looking to buy a steel building is, “How much does a steel building price for per square meter?” To be honest say it is really difficult to give a price by square meter ,mostly supplier give the price per square meter is reference or estimate price ,steel building is not common products , it is belong to building project which contain a lots of components and accessories ,in this article we will introduce the condition that effected the price of steel building .
There are three main factors affecting the cost of steel structure building:
First: the reason for raw materials
Steel and corrugated single color sheet the main components of the metal building, accounting for about 70%-80% of the total cost of the steel structure building. The fluctuation of the market price of steel structure raw materials directly affects the cost of the prefab steel building. The material of the section steel is also very different from the price of the carrier surface and the material and thickness of the wall and roof panel. The raw material of steel structure is the main factor in the construction cost of the shadow steel structure building.
Second: design factors
Design factors: Reasonable design could save raw materials to control the cost of building. Different steel building design schemes are an important reason for the change of raw material quantity, which directly affects the total cost of metal building
- The basic cost is closely related to the geology of the building. The construction period of the foundation construction accounts for about 25% of the total construction period of the building. The basic construction cost is 15% of the total cost of the steel structure workshop. When designing, we should pay attention to the geological report of the location of the plant, choose a reasonable basic type, and control the basic surface and depth of the foundation to play a positive role in the total cost of the steel structure workshop.
- Steel beam design: Rectangular section beam is the most common bending member, which is often used in design, but the material utilization rate is very low. First, because the material stress near the neutral axis is low; second, the bending moment of the beam varies along the beam length. Due to the low stress in most sections of the equal-section beam, the material is not well utilized, and the material utilization rate can be improved only when the axial force is applied. Therefore, the plane truss can be used instead of the rectangular beam in the design. The plane truss is equivalent to the hollow beam, and the excess material in the beam is removed, which is economical, and the weight can be reduced. It can also be developed into a space grid, and the utilization of materials can be greatly improved.
- Column net design: The column net layout is to determine the span and spacing of the column. When the process requirements permit, it is more economical to choose a small span door frame. Under normal circumstances, the optimal spacing of the portal frame is 6m-9m. When a large-tonnage crane is installed, the economic column distance is generally 7m-9m, and should not exceed 9m. When it exceeds 9m, the roof rafter, crane beam and wall frame The amount of steel used in the system will increase accordingly, and the cost will not be economic. Therefore, whether the grid layout is reasonable or not has a great impact on the cost of the steel structure plant.
Third: construction factors
The length of the construction period is also part of the cost of the steel structure building. The proficiency of the installation technology is the main reason for the length of the construction period. The construction of steel structure workshop is a systematic project involving a wide range of factors and many influencing factors. The construction period, policy changes, and large amount of engineering can all affect the cost of steel structure plant. Have an efficient and skilled installation team, can save the owner a lot of time and cost!
