Different degrees of open flatness, bearing capacity difference. And this carrying capacity is difficult to measure with the general strength index. Therefore, open the plate when the welding will have a great deal of welding deformation, it is difficult to adjust.So the appearance of the higher quality parts can not be used to open the flat plate.

Open plate is the original steel factory for the strip, a certain thickness, according to user requirements rolled into a certain thickness and width of steel. The original plate in the steel factory was rolled into GB required size. The original original Slab size strict, better performance, higher prices. Open flat relatively cheap, slightly different size. Flat board thickness of 1.5-20mm, made of Q235 and Q345. The main uses are non-pressurized containers and tanks.

Open flat features:

 First, the price is cheap and the length can be freely decided

 Second, easy to transport, without considering the size of the plate;

 Third, the cutting convenient, you can cut the expected size of steel plate;

 Fourth, you can effectively save material.
