How to Juge the Quality of Steel for Warehouse Storage Rack

Warehouse racks should follow principles. Suppliers of storage racking for quality heavy duty ought to have explicit certifications for the kind of item being showcased. The guidelines that ensure that modern racking has been arranged and put in the market in consistence with perceived quality necessities can be separated into 2 groups: first of all, principles connected with item quality and, furthermore, those related to the operation of the organization that produces or sells them.

Great racking suppliers will utilize Q235 cold rolled steel or comparative top notch steel, while poor providers tend to offer inferior quality steel from smaller factories.

As we said earlier, steel accounts for most of the racking cost. Therefore, some racking enterprises (1) reduce the total cost of warehouse rack projects by reducing the amount of steel used, and (2) produce storage racks with cheap and low-quality thin plates rolled by small rolling plants. For the former, we should advocate it under reasonable conditions. But we should try to avoid the latter as most of the structures of warehouse racks need to bear very large loads for a long time, the unstable mechanical properties and poor corrosion resistance of materials in small rolling plants will bring great hidden dangers to the daily safe use of storage racks.

So you may wonder why is the rolled steel from small rolling plants relatively poor 
This has a lot to do with the rolling equipment. Generally, large steel plants have the muscular financial strength and advanced production equipment. From steel billet to rolled steel, they are formed at one time at high speed, which can accurately control the overall cooling temperature of steel and ensure the stability of the mechanical properties of steel. The Fe-C crystal on the steel surface is stable and dense with strong corrosion resistance.

While small rolling manufacturers lack such equipment the finished item needs to be heated many times. In the process of multiple heating, the steel temperature is difficult to control, and the mechanical properties of different parts of the material will be different. At the same time, Fe-C crystal will be diverse and unstable, with poor surface compactness and weak corrosion resistance.
