济南型钢由热卷和冷弯成型，壁薄、重量轻、截面性能优良、强度高。与传统槽钢相比，同等强度可节省材料30%。通过以上介绍，镀锌型钢具有尺寸可调、抗压强度高等优点。冷弯型钢的截面尺寸虽然比较轻，但非常符合屋面檩条的受力特性，充分利用了钢材的机械效率。

Jinan section steel is formed by hot coil and cold bending, with thin wall, light weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials. Through the above introduction, galvanized section steel has the advantages of adjustable size and high compressive strength. Although the section size of cold-formed steel is relatively light, it is very consistent with the stress characteristics of roof purlins and makes full use of the mechanical efficiency of steel.

各种配件也可以连接成不同的组合，外形美观。使用型钢檩条可以减轻建筑屋面自重，减少工程用钢量，故又称经济型。是替代槽钢、角钢、角钢等传统型钢檩条的新型建筑材料。钢管。

Various accessories can also be connected into different combinations, with beautiful appearance. The use of profiled steel purlin can reduce the dead weight of the building roof and reduce the amount of steel used in the project, so it is also called economical purlin. It is a new building material to replace traditional steel purlins such as channel steel, angle steel and angle steel. Steel pipe.

镀锌型钢表面光滑，锌层均匀，附着力强，尺寸精度高。所有表面均镀锌，表面锌含量通常为120-275g/。使用寿命长，耐腐蚀，经久耐用，是一种高防护性的镀锌型钢。

Galvanized section steel has smooth surface, uniform zinc layer, strong adhesion and high dimensional accuracy. All surfaces are galvanized and the surface zinc content is usually 120-275g/. Long service life, corrosion resistance, durability, is a kind of high protective galvanized steel.

加工中三个常见问题的解决方法

Solutions to three common problems in machining

1、型钢横向运行角度偏差小：通过调整进料端夹送轮来调整。如果左侧较小的一侧较大，则松开左端的压轮并拧紧右端的压轮。

1. Small lateral running angle deviation of profile steel: adjust by adjusting the pinch wheel at the feeding end. If the smaller side on the left is larger, loosen the pressure roller on the left end and tighten the pressure roller on the right end.

2、型钢横向弯曲：当型钢向左端弯曲时，松开出料端的第二排左压辊，拧紧右压辊。

2. Transverse bending of section steel: when the section steel is bent to the left, loosen the second row of left press roll at the discharge end and tighten the right press roll.

3、济南型钢纵向弯曲：型钢向上弯曲时，向下压一排矫直轴，向下弯曲时，向上推第二排矫直轴。

3. Longitudinal bending of Jinan section steel: when the section steel is bent upward, press down a row of straightening shafts, and when it is bent downward, push up the second row of straightening shafts.
