What is the production of steel structures? What distinctive features of the technological process should be observed when performing work, and what are the consequences of non-compliance with the established tolerance standards in their manufacture?
First of all, it should be noted that with large-scale, large-sized construction, one cannot do without a serious manufacturer. So that small enterprises do not promise you, no matter what conditions of cooperation they offer, do not fall for their attractive slogans. Choosing a serious organization with a long history and solid foundation is what you should pay attention to.
It is a large manufacturer who is able to fulfill all stages of the technological line in accordance with international norms and rules. Now it is enough to simply find a manufacturer of quality products even in China. Moreover, there is already a special service that allows you to find a manufacturer in China, place an order for him and receive a commercial offer.
The first stage in the execution of work in the manufacture of trusses, however, as well as other metal structures - girders, columns, channels, etc., is precise cutting of metal, strictly according to specified dimensions. Then, assembly is performed. Moreover, the assembler must be a highly qualified specialist who is perfectly versed in drawings, welding, and tolerance standards. The assembled product is sent for welding, where it is scalded. After that, the product is sanded. At the final stage of the assembly, all the necessary holes are drilled, and, if necessary, if the product has acquired irregular shapes - "led by welding", it is leveled by specialists by heating in certain places.
Manufactured structures undergo mechanical, ultrasonic, and sometimes X-ray inspection. After that, the quality control department checks compliance with all the parameters of the product.
Before the individual elements of the assembly go to the paint shop, they are assembled on special "zero" platforms to make sure that the whole structure is assembled accurately.
The final stage is painting the product in special drying chambers. Now the structure is protected and will carry the loads placed on it for many decades.
