Cold rolled in the industry can also known as cold rolled plate, coil manufacture. The origin of these names because of the classification of the cold-rolled products, cold rolled concrete is divided into cold plate and cold rolled two main class. And cold plate can be referred to as a manufacture, cold rolled plate; Cold roll can be called cold rolled coil, cold plate volumes.

1, appearance and surface quality: because of the cold plate is, resulting from the hot plate in cold rolling process and cold rolling at the same time also will make some surface finishing so cold plate on the surface quality (such as surface roughness, etc.) better heat plate, so if the product after the sequence on the paint coating quality has high requirements, such as general choice of cooling-plate

2, performance: in general, hot plate and pipes in the engineering mechanical properties are no more thought, although there are certain work hardening heat pipes in the process of cold rolling, (but do not rule out strict in mechanical properties, that is need to discriminate), cold plate heat plate usually slightly high yield strength, surface hardness is higher, what specific needs to see the degree of cold plate annealing. But no matter how annealing cold plate strength is high specific heat plate.

We are always good packaging products

We always pay attention to every detail, very good guarantee the quality of the product
