Angle steel inspection standards

Angle steel is a common building material. The inspection standards for its specifications and dimensions mainly include the following aspects.

1. Appearance standards of angle steel:

For the appearance standards of angle steel, it is mainly to check whether its surface is flat and smooth, and whether there are obvious cracks, folds, slag inclusions and other defects;

At the same time, check whether there are oil stains, rust and other problems on the surface of the angle steel.

2. Dimensional standards for angle steel:

It mainly includes the length, width, thickness and other aspects of the angle steel.

Among them, the length of the angle steel should meet the standard requirements and be measured and inspected.

In addition, there are strict requirements for the width and thickness of angle steel, and tools need to be used for measurement and inspection.

3. Sectional shape standards of angle steel:

Mainly including its cross-sectional shape and size.

The shape of the angle steel section can be divided into different types such as right angle type, arc type, obtuse angle type, etc., which need to be measured and inspected according to specific requirements.

In addition, the size of the angle steel section also needs to be measured and inspected to ensure that it meets the requirements stipulated in the standard.

4. Quality standards of angle steel:

The quality standards of angle steel are very important, mainly to check whether the material is qualified.

Steel generally needs to be checked for its chemical composition, mechanical properties and other indicators to ensure that it meets standard requirements.

5. Defect standards of angle steel:

The defect standard of angle steel refers to the inspection and evaluation of surface and internal defects of angle steel.

Common angle steel defects include slag inclusions, burns, cracks, defects, etc.

Appropriate instruments and testing methods need to be used for inspection to ensure that the quality of angle steel meets standard requirements.
