The importance of thickness control of perforated steel plates

The national standard has clear requirements for the thickness tolerance of medium and thick steel plates in punching mesh. The thickness of the steel plate measured at any point shall not exceed the allowable deviation range.

At the same time, the standard also stipulates that, except for special provisions in the contract, the steel plate shall be delivered according to the theoretical weight, which is calculated according to the nominal thickness, length and width. The theoretical weight of a steel plate with an area of 1㎡ and a thickness of 1mm is equal to 7.85kg.

The thickness of the steel plate is one of the important factors of the quality of the steel plate. Strictly controlling the thickness of the steel plate is necessary to ensure the supply conditions. Controlling the thickness of the steel plate according to the negative tolerance is an important way to reduce metal consumption and improve the yield rate. The current metal consumption statistical structure shows that the thickness tolerance loss accounts for 36% of the total consumption.

Strictly control the thickness tolerance of the steel plate so that the same plate difference and the difference between plates are controlled within the minimum tolerance range.

Due to the reduction of the same plate difference, the plate shape and plane shape are improved, the amount of cutting head, tail and edge cutting is reduced, and the plate shape defects are also reduced. Therefore, improving the accuracy of steel plate thickness has always been valued by the current market.

Therefore, when punching holes in steel plates, you must choose steel plates of appropriate thickness to avoid waste.
