按照钢的冶炼质量不同，型钢分为普通型钢和优质型钢。普通型钢按现行金属产品目录又分为大型型钢、中型型钢、小型型钢。 采用钢板或钢带冷弯成型制成。它的壁厚不仅可以制得很薄，而且大大简化了生产工艺，提高生产效率。 可以生产用一般热轧方法难以生产的壁厚均匀但截面形状复杂的各种型材和不同材质的冷弯型钢。 冷弯型钢除用于各种建筑结构外，还广泛用于车辆制造，农业机械制造等方面。槽钢是截面为凹槽形的长条状钢材。 槽钢属建造用和机械用碳素结构钢，是复杂断面的型钢钢材，其断面形状为槽形。槽钢主要用于建筑结构和车辆制造等。 在使用中要求其具有较好的焊接、铆接性能及综合机械性能。 According to the different smelting quality of steel, the type steel is divided into ordinary type steel and high-quality type steel. Ordinary steel is divided into the current metal product catalogue: large steel, medium steel and small steel. Ordinary steel can be divided into I-word steel, groove steel, corner steel, round steel, etc. Cold bending steel is the main material for making light steel structure, made of cold bending molding of steel plate or steel belt. Its wall thickness can not only be very thin, but also greatly simplifies the production process and improves the production efficiency. A variety of profiles which is difficult to produce with uniform wall thickness but complex section shape and different materials of cold bent steel can be produced.In addition to being used in various building structures, cold-bent steel is also widely used in vehicle manufacturing, agricultural machinery manufacturing and other aspects.Sute steel is long strip steel with concave section. Slot steel is carbon structural steel for construction and machinery. It is a type steel steel of complex section. Its section shape is groove shape.Slot steel is mainly used for building structure and vehicle manufacturing. It is required to have good welding, riveting performance and comprehensive mechanical performance in use.
