Product Overview

Cold rolled steel strip

GuangWeiYouLiang's Cold-rolled steel strip is hot rolled coil as raw material at room temperature below the condition of recrystallization rolling, including board and roll Strip after pickling in the cold rolling mill rolled to finished thickness, typically without intermediate annealing, each rack (or pass) reduction rolling according to the pressure distribution, power and speed mill promised, taking into account the yield , quality and other factors making.

One of most important factor is Lubrication Technology in the production:

Lubrication and cooling effect. Generally with good cooling performance emulsion, good lubricating performance when rolling thin or hard metal pure oil lubricants,

Our cold-rolled steel strip has these features:

high straightness,

nature bright surface finish,

surface clean and bright, no burr, rust, sand hole, and break

easy-to-perform coating processing,

but also has high performance and not punching aging characteristics of low yield point,

GuangWeiYouLiang's Cold rolled steel coil with a wide range of uses, mainly used in the automotive, printing drum, construction, building materials, bicycles, and other industries.
