2021 China New Design Alloy Steel Coil - Cold rolled steel strip sheet coil manufacturer – Lu

Introduction

Cold-rolled steel strip refers to the use of hot-rolled steel strip and steel plate as raw materials, which are rolled into strip steel and sheet steel by a cold rolling mill at room temperature. Generally, the thickness is 0.1-3mm and the width is 100-2000mm. Cold rolled strip or plate has the advantages of good surface finish, good flatness, high dimensional accuracy and good mechanical properties. Usually the products are in rolls, and a large part of them are processed into coated steel plates. There are many varieties of cold-rolled strip steel products, and the production processes are also different. The varieties of cold-rolled strip steel mainly include carbon structural steel, alloy and low-alloy steel plates, stainless steel plates, electrical steel and other special steel plates. Representative cold-rolled steel strip products are metal-coated sheets (including tin-plated sheets and galvanized sheets, etc.), deep-drawn steel sheets (most of which are automotive sheets), electrical silicon steel sheets, stainless steel sheets, and coated (or composite) steel sheets Wait. The supply of cold-rolled strip steel products is in the form of plates, coils, or slit strips, which depend on user requirements.
