Squareness refers to the degree to which the actual angles at the four corners of a steel plate deviate from a right angle.

Cold-rolled sheets are produced via a cold-rolling process; their surfaces are free of mill scale, resulting in high quality. Hot-rolled sheets, conve

Cold-rolled steel sheets are characterized by their high surface quality and excellent dimensional precision, making them widely utilized across numer

These advancements have resolved critical issues—such as welding instability, a high propensity for strip breakage, and rolling mill vibration—thereby

Cold-rolled products are flat-rolled metal materials manufactured from hot-rolled coils as raw material, processed at room temperature through process

The primary characteristics of hot-rolled products include high strength, excellent toughness, and good ductility.

Hot-rolled coils are produced using slabs (primarily continuously cast slabs) as raw material; after being heated in a reheating furnace (or homogeniz

Hot-rolled coil is a steel strip product produced by heating steel billets to high temperatures and subsequently rolling them. Its primary material co
