Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.
Production process:
Due to no heating, there are no pitting and scale defects in hot rolling. The surface quality is good and the surface finish is high. Moreover, the dimension precision of cold rolled products is high, and the properties and structure of products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc.
Performance: mainly made of low carbon steel, with good cold bending and welding performance, as well as certain stamping performance.
SPCC is commonly used cold rolled carbon steel sheet and steel strip.
SPCC Specification
Features of cold-rolled steel plate:
1, Cold rolled steel plate thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.
2. The maximum thickness of cold-rolled steel plate is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel plate in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.
3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.

Galvanized GI Steel Rolls & Plates & Coils
Whatâ??s the difference between galvanized GI steel coils and plates?
I. Definition
Galvanized GI Steel coil and galvanized sheet are galvanized steel. The galvanized coil is a continuous hot dip galvanized coil in the production process. While galvanized sheet is a single hot dip galvanized sheet in the production process.
2. the production process
The production process of galvanized coil and galvanized sheet is different.
The production process of galvanized coil generally includes multiple processes such as coil heating, hot dip galvanizing and shearing into coil.
The galvanized sheet is generally the zinc alloy coating through the hot dip technology directly coated to the surface of the steel plate.
So the production process is relatively simple, the process difficulty is relatively low.
3. material thickness
The material thickness of galvanized coil and galvanized sheet is also slightly different.
Generally speaking, the thickness of galvanized coil is relatively thin. We mainly use it for the production of cold rolled, coating and other thin steel products.
The thickness of galvanized sheet is relatively thick. We mainly use it in the manufacture of glass fiber reinforced plastic, automotive panels, roof panels and other steel products requiring strength and corrosion resistance.
4. Advantages and Disadvantages
Both galvanized coil and galvanized sheet have their own advantages and disadvantages.
The production cycle of galvanized coil is short, the process is simple, and it is suitable for the production of low thickness and high precision steel products.
The galvanized sheet has the advantage of hardness, corrosion resistance, wear resistance and other multiple properties.
However, the production process of galvanized sheet is time-consuming and laborious, and the production cost is relatively high.
5. Application fields
The application areas of galvanized coil and galvanized sheet are also different.
Galvanized coil is usually used in the production of home appliances, building materials, auto parts, pipes and other high-demand steel products.
The galvanized sheet is mainly used in automobile manufacturing, construction engineering, petroleum, chemical and other industries.
In addition, because of the good corrosion resistance of galvanized sheet, it is also widely used in Marine engineering, railway, bridge and other fields.
