Steel structure engineering is mainly made of steel structure, is one of the main types of building structure.It is characterized by steel beams, steel columns, steel trusses and other components made of profiled steel and steel plates; the structure with welded joints, bolts or rivets is one of the main types of building structures.Compared with other constructions, steel structure has advantages in use, design, construction and comprehensive economy. It has low cost and can be moved at any time. 　　

 The price of steel structure engineering plant is one of the problems that many customers pay attention to first. Many customers will directly pay attention to the relevant price. Through different comparison and qualification of each company, they will finally choose and establish a good engineering company. The price is also a part of the factors influencing customers’ choice.For many customer service, after the call is connected, many customers will directly ask, how much is the area, length, height, width, etc., and how much it costs to build a steel structure workshop per square meter. In the face of such problems, professional customer service can answer for you, but some non professional customer service may not be able to provide detailed answers for you. In fact, customer service is not Often helpless.

If the customer service can’t say the price, the customer will think that you are not professional; but if the price said by the customer service is not consistent with the final actual price, the customer will also feel that the three-dimensional steel structure is not professional.From the customer’s point of view, it’s not unreasonable to hope to be able to compare goods with three stores. However, there will be the idea that “the price is too cheap, but there is no reason why it is too expensive”.This is also one of the reasons why most customers give up communication directly after hearing the quotation from the construction company.Do you know how complicated the quotation of a steel structure factory building is?

 　　1.Geographical location factors of steel structure engineering: 　　

 The geographical location will determine the living standard, income level and price of a city. The quotation for the same steel structure engineering plant in the first tier city, the second tier city and the third tier city will certainly be different.The construction company should not only consider the cost of the project, but also consider the wages of the front-line construction personnel, whether it is safe or not, if there is a construction accident, medical treatment situation! 　　

 Therefore, customers should have a rough estimate of their own project requirements before asking for quotation, so that they will not feel that there is any price problem after listening to the quotation from the construction company.

 　　2.Raw material factors of steel structure engineering 　　

 Steel structure workshop project is mainly composed of steel and plate, which account for about 70% ~ 80% of the whole steel structure project plant cost. The fluctuation of steel structure raw material market price will directly affect the quotation of steel structure engineering plant. The material and load surface of section steel, the thickness of enclosure plate and material have great difference.The raw material of steel structure is the main factor affecting the cost of steel structure engineering workshop.

Customers should have a steelyard in their heart before asking, so that they can have a bottom in their hearts when facing the final offer

 　　3.Design factors of steel structure engineering 　　

 The design drawings directly determine the amount of materials used in this project, so the construction drawings must be rationalized.Let’s take a look at the details

 　　1.Basic design: 　　

 The foundation cost is affected by the geological conditions where the plant is located. The construction period of the foundation accounts for about 25% of the total construction period of the plant, and the foundation cost is 15% of the total cost of the steel structure engineering workshop.In the design, attention should be paid to the geological report of the place where the plant is located, select a reasonable foundation type, and control the bearing surface and buried depth of the foundation, which has played a positive role in the total cost of steel structure engineering workshop.

 　　2.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.One is that the stress of the material near the neutral axis is low; the other is that the bending moment of the beam varies along the length of the beam.Due to the low stress in most sections of the beam with constant cross-section, the material can not be used well. Only when the axial force is applied, the material utilization rate can be improved.Therefore, the plane truss can be used to replace the rectangular beam in the design. The plane truss is equivalent to the hollowed beam, and the surplus material in the beam is removed, which is economical and can reduce the self weight.It can also be developed into space grid, and the utilization rate of materials can be greatly improved.

 　　3.Column network design: 　　

 The layout of column network is to determine the span and spacing of columns. It is more economical to choose the portal frame with small span as far as possible when the process requirements permit.In general, the optimal spacing of portal frame is 6m-9m. When large tonnage crane is set, the economic column spacing is generally 7m-9m, which should not exceed 9m. When it exceeds 9m, the steel consumption of roof purlin, crane beam and wall frame system will also increase correspondingly, and the cost is not economic.Therefore, whether the column network layout is reasonable or not has a great impact on the cost of steel structure engineering workshop.
