Cold rolled steel coil: what it is
Cold rolled coil is made by rolling steel strip, usually pickled hot rolled coil, below its recrystallization temperature. The strip comes out thinner, with a better surface finish and tighter tolerances than hot rolled strip. The coil offered here is 0.20 to 3.00 mm (0.008 to 0.118 in) thick and 600 to 1600 mm (23.62 to 62.99 in) wide, and follows EN 10130.
Full Hard and annealed coil
Straight from the cold rolling mill the strip is Full Hard: strong, hard and work-hardened, and not meant for forming. Annealing relieves the stresses of cold rolling and softens the steel, and a light temper rolling pass then sets the final shape, surface and mechanical properties. Choose Full Hard coil when you need strength, or when you will process the strip further yourself, and annealed coil when the part is formed, drawn or pressed.
Full-width coil and slit coil
Full-width coil is supplied in widths from 600 to 1600 mm (23.62 to 62.99 in) on an inner diameter of 508 to 610 mm (20.00 to 24.02 in). Slit coil is full-width coil cut lengthwise into narrower coils, with widths from 20 to 1500 mm (0.787 to 59.06 in). Slit coil suits production lines that need a fixed, narrower strip width. Slit width, tolerance and the number of strips per coil are agreed at quotation, and you can request a quote for either form.
Standard, grades and the rest of the range
EN 10130 covers cold rolled, uncoated low carbon steel for cold forming, with grades named DC01 to DC06. Which grades are available depends on the mill and on whether the coil is Full Hard or annealed, so state both when you ask for a quotation. Cold rolled coil is also the base for coated products: see galvanized coil and prepainted steel coil, or the whole steel coil range. Reinwent is a trading and sourcing company, and this coil is sourced from manufacturers in Türkiye.
Questions buyers ask
What is cold rolled steel coil?
It is steel strip that has been rolled below its recrystallization temperature, usually from pickled hot rolled coil, to reduce its thickness. Cold rolling improves the surface finish and holds tighter tolerances than hot rolling.
What is the difference between Full Hard and annealed coil?
Full Hard coil is cold rolled strip that has not been annealed, so it is strong and hard and is not made for forming. Annealed coil has been softened by annealing and then temper rolled, which gives the ductility, flatness and surface needed for forming.
What is temper rolling?
Temper rolling, also called skin pass, is a light final cold rolling pass after annealing. It sets the final mechanical properties, shape and surface finish of the strip.
What thickness and width does cold rolled coil come in?
Thickness runs from 0.20 to 3.00 mm (0.008 to 0.118 in) and width from 600 to 1600 mm (23.62 to 62.99 in). The coil inner diameter is 508 to 610 mm (20.00 to 24.02 in) and coils weigh up to 30 tonnes (about 66,100 lb). The exact limits depend on the mill and on whether the coil is Full Hard or annealed, so they are confirmed at quotation.
Which standard applies to cold rolled coil?
EN 10130 covers cold rolled, uncoated low carbon steel for cold forming, and its grades are named DC01 to DC06. Which grades are available depends on the mill, so name the grade when you ask for a quotation.
What is the difference between hot rolled and cold rolled coil?
Hot rolled coil is rolled above the recrystallization temperature of the steel and cold rolled coil below it. Cold rolled coil is thinner and has a better surface and tighter tolerances, and it needs an extra rolling and annealing stage to make.
What is slit coil, and can cold rolled coil be slit?
Slit coil is full-width coil cut lengthwise into narrower coils. Slit widths run from 20 to 1500 mm (0.787 to 59.06 in) within the thickness range of the coil. Slit width, tolerance and coil weight are confirmed at quotation.
What is cold rolled coil used for?
Buyers use it for household appliances and furniture, automotive parts, radiators, ventilation and filter equipment, and for parts that are painted or coated afterwards. Full Hard coil suits uses that need strength rather than forming.
How do I request a quotation for cold rolled coil?
Send the thickness and width in millimetres, whether you need Full Hard or annealed, the grade or standard, full-width or slit coil, the coil weight, the quantity and the destination through the quote form on this site. Reinwent sends the quotation within 12 hours at the latest.
