Cold-rolled sheet is a product obtained from hot-rolled sheet by cold pressure processing. The surface quality of the cold rolled sheet is superior to that of the hot rolled sheet, and good mechanical properties can be obtained after heat treatment. According to the different needs of production enterprises, cold rolled plate is usually divided into: general cold rolled plate, stamping grade cold rolled plate, deep drawing, extra deep) medium and super deep intermediate cold rolled plate, generally delivered by coil and plate.

Cold rolled steel is the steel produced by cold rolling, under certain conditions, the steel plate can be further pressed into the required thickness, it and hot pressed steel plate compared, the thickness will be more accurate, and the surface is more smooth and more beautiful. At the same time, it also maintains stable performance, such as processing skills are very good, but they are not suitable for processing, so they need to be handed over to customers by annealing.

The deep drawing performance of DC01, DC02, DC03 and DC04 is different. DC is DIN 1623-1 flat steel products of low carbon steel cold rolled strip and thin steel plate meaning; DC is DIN 1623-1 . 01, 02, 03, 04 indicate different deep drawing performance levels, and the larger the number, the better the performance.Cold-rolled steel is steel produced by cold rolling, and compared with hot-pressed steel, the thickness will be more accurate, and the surface is more smooth and more beautiful.

s235 is a carbon structural steel with low carbon content, the carbon content is about 0.05%-0.70%, and the individual can be as high as 0.90%. Can be divided into ordinary carbon structural steel and high-quality carbon structural steel two categories. Many uses, the amount is large, mainly used in railway, bridge, all kinds of construction projects.

Implementation standard: GB 1499.2-2007,Rebar is the common name of hot rolled ribbed steel bar. The grade of ordinary hot-rolled steel bar consists of HRB and the minimum yield point of the grade. H, R and B are the first letters of the words Hotrolled, Ribbed and Bars respectively.
Hot rolled ribbed steel bars are divided into two grades HRB335(old number 20MnSi), three grades HRB400(old number 20MnSiV, 20MnSiNb, 20Mnti) and four grades HRB500.

Implementation standard: GB 1499.2-2007.In the identification of seismic steel rebar, "E" is the symbol of seismic steel rebar strip.Seismic rebar is a kind of steel bar with seismic performance, which is widely used in the construction of civil engineering such as houses, Bridges and roads to improve the stability and safety of buildings ‌.

Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete, and its cross section is round, sometimes square with rounded corners. Including round steel bar, ribbed steel bar, torsion steel bar.
The steel bar for reinforced concrete refers to the straight bar or disc bar steel used for reinforced concrete reinforcement, and its shape is divided into two kinds of round steel bar and deformed steel bar, and the delivery status is straight bar and disc round two kinds.

200 series stainless steel includes: 201,201LN, 202,204L,205, 206,2205,etc.
Chromium-manganese (200 series) austenitic stainless steel is based on chromium-nickel austenitic stainless steel, is to add manganese and (or) nitrogen to the steel instead of the precious metal nickel and developed, its austenitic elements, in addition to manganese and nitrogen, generally there is an appropriate amount of nickel (4%~6%).

300 series stainless steel includes: 304、304L、316、316L、301、301L、302、302B、303、303Se、304H、304N、304LN、305、308、309、309S、310、310S、310MoLN、316Ti、316Nb、316N、316LN、317、317L、317LMN、317LN、321、321H、330、347、347H.
The 300 series stainless steel, also known as 18-8 steel, is the most commonly used material for fasteners, joints, pipes and pipes, which have good corrosion resistance on the surface.

400 series stainless steel includes: 405, 410L, 430, 430F, 434, 447J1, XM27. Martensite: 403, 405, 410, 410J1, 416, 420, 420J1, 420J2, 431, 440A, 440B, 440C, 440F.
400 series stainless steel is an alloy of iron, carbon and chromium. Because it does not contain nickel, it is a nickel-free stainless steel, also known as stainless iron.

H-shaped steel is a kind of economically efficient profile with more optimized section area distribution and more reasonable strength-to-weight ratio, which is named because its section is the same as the English letter "H". Because all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used.
