 What is the difference between the general board and the medium board

Common plate is the abbreviation of ordinary hot-rolled carbon steel plate, which generally refers to the thin plate made of Q235 series. The medium plate generally refers to the hot-rolled plate of more than 20mm to less than 50mm. Coil, as the name implies, refers to steel coils, which must be flattened before they can be used. The common thickness is between 2mm-20mm, and the common materials are Q235, Q345, etc. Coils are also divided into hot-rolled coils, cold-rolled coils, stainless steel coils, and patterned coils. etc.

Generally refers to hot-rolled thin coils. The flat plate refers to the steel plate after the coil is flattened, and the coiled plate cannot be used without flattening. To put it simply, it is to spread the coiled plate and cut it into a certain length of steel plate.

The two are completely different classification methods, roughly speaking: common steel refers to steel grades, that is, common carbon steel, Q235 and other steel grades; it is equivalent to low-alloy high-strength steel. The common plate can be a medium plate; it can also be an open flat plate of a hot rolled coil.

Medium and heavy plate refers to the type of steel plate, roughly 6mm or more, and the steel plate produced by the medium and heavy plate rolling mill (most of which have widening and rolling), is equivalent to the saying of hot continuous rolling flat plate (without widening). There are many steel types in medium and heavy plates, such as ordinary plates, low alloy plates, high strength plates, container plates, bridge plates, etc.
