High Dimensional Precision
Cold-rolled angle steel is produced through the cold-rolling process. During the cold rolling process, the steel is extruded by rollers at room temperature, enabling precise control of the dimensions of the angle steel. For example, the tolerance of its side lengths can be controlled within a very narrow range, generally achieving an accuracy of ±0.5mm or even higher. This makes cold-rolled angle steel highly suitable for structures with high requirements for dimensional accuracy, such as precision mechanical frames and metal structures for high-end building decoration.
Good Surface Quality
The surface of cold-rolled angle steel is relatively smooth. This is because the cold-rolling process can effectively reduce impurities such as mill scale on the surface of the steel and make the surface of the steel more even during the rolling process. Its surface roughness Ra value is usually low, generally ranging from 3.2 to 6.3μm. This good surface quality enables cold-rolled angle steel to achieve an aesthetic effect without excessive surface treatment when used in occasions with high requirements for appearance. For example, for some indoor metal decorative components, using cold-rolled angle steel can directly display the metallic texture and enhance the decorativeness.
Excellent Mechanical Properties
High Strength: The cold-rolling process refines the grains of the angle steel, thereby increasing its strength. Its yield strength is usually higher than that of hot-rolled angle steel, generally reaching 300 - 500MPa. This enables cold-rolled angle steel to withstand greater external forces and performs excellently in some structures that need to bear large loads. For example, in the frame structure of light-duty shelves, cold-rolled angle steel can provide sufficient strength to support the weight of the goods.
Good Toughness: Although it has undergone cold-rolling processing, cold-rolled angle steel still maintains good toughness. This is because, under appropriate cold-rolling process parameters, the internal organizational structure of the steel is not overly damaged. When subjected to impacts or vibrations, cold-rolled angle steel can absorb a certain amount of energy without brittle fracture.
