Product Details

The cold-rolled plate is characterized by excellent plate type, surface quality and mechanical performance indicators to meet users' requirements. It has been widely applied in galvanized substrate, home appliance, barrel, auto, industry, enamel and other industries.

Cold-rolled plate is manufactured with hot rolled steel coils through rolling at the ambient temperature under the recrystallization temperature. Cold-rolled steel plate is manufactured through the cold rolling process. The cold-rolled steel plate is usually 0.1-8.0mm thickness. Most cold-rolled steel plates manufactured are less 5mm thick. The thickness and width of cold-rolled plates are subject to the equipment capacity and market demands of each factory.

The steel structure made of steel materials is one of the major building structure types. The structure is mainly composed of steel beam, steel column, steel truss and other steel components made of profile steel and steel plate and applies derusting process, including silanization, pure manganese phosphating, rinsing and drying, zinc coating, etc. Components or parts are usually connected by welding joints, bolts or rivets. It is widely applied in large factories, venues, super high-rise buildings, etc.
