Cold rolling is hot rolled sheet roll as raw material, at room temperature in the recrystallization temperature for rolling, cold rolled steel plate is through the cold rolling process production of steel plate, referred to as cold plate. The thickness of cold rolled plate is generally between 0.1-8.0mm. The thickness of cold rolled steel plate produced by most factories is below 4.5mm. The thickness and width of cold rolled plate are determined according to the equipment capacity and market demand of each factory.

Hot rolled steel is after high temperature heating rolled steel, its strength is not very high, but enough to meet our use, its plasticity, weldability is good, so we are more commonly used; Cold rolled steel is common hot rolled steel after strong drawing beyond the strain hardening stage of steel, it has high strength, but poor toughness, weldability, relatively hard and brittle. Hot rolling is processed at high temperature. Hot rolling means that the material needs to be heated during or before steel rolling. Generally, rolling should be heated to the recrystallization temperature above.

SS400 is one of the most commonly used hot rolled general structural steel.SS400 steel plate, JIS3101 SS400 steel plate, under JIS3101 standard, we can regard SS400 steel plate as Carbon and low alloy steel SS400 steel plate is one mainly of Carbon and low alloy steel, SS400 steel plate would be used to built containers which can bear low temperature sea water.

S335JR - an useful structural grade steel with a minimum yield strength of 355 N/mm². S355 being widely used in the structural engineering and construction industries, S355 offers high yield and tensile strength and is supplied with a variety of treatments and test options to ensure that it is a highly usable steel in your various projects.

S275N/S275NL belongs to the European standard carbon structural steel plate, represents the European standard structural steel; "275" : indicates that the thickness of the steel plate is less than or equal to 16mm, and the yield strength is at least 275Mpa; N: indicates the minimum impact energy when the temperature is not lower than -20 ° C. L: indicates that the shock temperature of the S275NL is -50 ° C.

Plates are available up to 3.5m wide and 14m long. Most plates are certified to EN10204 3.2 and normally come from a European mill – typically Tata, Arcelor or Clabecq so you can be assured of good quality in these commodity steel plates. S235JR is equivalent to DIN:ST37-2, JIS:SS400, ASTM:A283C and UNI:FE360B
