Product strip is all kinds of rolled steel enterprises in order to adapt to different industrial sectors to industrial production to the needs of all kinds of metal or mechanical products and production of a narrow and long steel plate. The strip also known as strip width less than 1300mm in length according to the size of each volume is slightly different. The strip is widely used in the production of welded steel pipes for cold-formed steel billet manufacturing bicycle frames, wheels, clamps, washers, springs, saw blades, metal products and blades, etc.. Cold-formed steel cold rolled strip production process generally: pickling → rolling → process lubrication → annealing → flat → Cut → packaging.

The size specifications of the strip (thickness) * (W) A (0.05,0.06,0.08) * (5-100), 0.10 * (5-150) C, (0.15-0.80, in steps of 0.05) * (5 -200) D, (0.85-1.50, in steps of 0.05) * (35-200) E, (1.60-3.00 in steps of 0.05) * (45-200) 2, bicycle cold rolled wide strip (GB3644-89) (1 ) main use bicycles rickshaw materials. (2) of the main purposes of the grades and chemical composition of the material, hot-rolled quality carbon structural steel strip (GB8749-88) (1) The main purpose as a cold-rolled strip steel billets, can also be used in the manufacture of bicycles, sewing machine parts and hardware manufacturing. (2) The grade of material and chemical properties comply with the provisions of the GB699 (quality carbon structural steel technical conditions). (3) the strip specifications of size and production units strip thickness of 2.50-5.00mm (difference 0.25), width 100-250mm. 2, hot-rolled stainless steel strip (GB4230-84) divided by organizational characteristics austenitic, austenitic, ferritic, ferritic, martensitic and precipitation hardening five categories. (1) Key Features and Uses (2) material grades and chemical composition, mechanical properties comply with the provisions of GB1220-84 to see thick steel (hot-rolled stainless steel) part. (3) the strip specifications size and production units strip thickness 8.0mm width of the 30-120mm; long-distance 2-10m straight into a volume supply. , Watch hot and cold-rolled stainless steel strip (GB5215-85) watch with a stainless steel strip that watch with stainless steel flat points on hot-rolled, cold-rolled two. Increase in the production process, the sulfur content of certain grades and joined the cutting elements copper, calcium, mentioning custody the storage strip thickness 6-9mm (hot-rolled); 4-6mm (cold); width of 60-85mm ( hot-rolled); 30-60mm (cold). 4 hot rolled high electric resistance alloy with (GB1234-85) rolled high electric resistance alloy with commonly known as nickel-chromium alloy with. (1) The main use for the manufacture of electric stove, a civilian electrical heating element and resistor pieces. (2) the grade of the material and the chemical composition of hot-rolled high electric resistance alloy strip material grades CR20Ni80, Cr15Ni60, 1Cr13Al14, 0Cr25Al5, 1Cr25Al9 and 9Cr18 etc., the chemical composition of the symbol of the provisions of GB1234-85. (3) the specification of the alloy with the size and production unit strip thickness 2-6mm; width of 20-100mm; the length ≥ 5m or weight of 8kg Other Description 1, high-quality cold-rolled steel strip (GB3526-83) rolled low carbon steel quality carbon structural steel in low-carbon steel (08,10,08 Al), as a material, made by cold rolling. Cold rolled low carbon steel strip their surface quality is divided into Ⅰ, Ⅱ, Ⅲ three groups; ordinary precision (P) divided their manufacturing precision, high accuracy thickness (H), the thickness of the high-precision (J), the width of the higher accuracy (K), width and thickness of the five categories of high accuracy (KH) strip; according to their degree of hardness is divided into special soft (TR), Soft (R), semi-soft (BR), the low hard (DY), cold Hard (Y) used in the manufacture of the operating frequency in the above 400HZ power transformers, pulse transformers, magnetic amplifiers, switches, and other core in the strip transactions.
