Do you know how the angle steel is punched and the method?

Many people are curious, for steel such as angle steel, so strong, if you want to make a hole, how should you do it? The following is the introduction of how the angle steel is punched and the method made by the manufacturer of Sans Raintech:

1. Method:

With an cnc angle steel punching shearing marking machine, you can adjust the impact without impact before drilling. First use a small drill to drill a small hole and then use a large drill to expand the hole. The drill must be a twist drill. Like this image:

2. Brief introduction of angle steel:

Angle steel manufacturer Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle. There are equilateral angle steel and unequal angle steel. The two sides of an equilateral angle are equal in width. Its specifications are expressed in millimeters of side width x side width x side thickness. Because the model does not represent the size of different side thicknesses in the same model, it is necessary to fill in the side width and side thickness dimensions of the angle steel in the contract and other documents, and avoid using the model number alone. The specifications of hot-rolled equilateral angle steel are 2#-20#. Angle steel can be composed of various stress components according to different needs of the structure, and can also be used as a connector between components. Angle steel is currently widely used in various building structures and engineering structures.
