After the type of channel is not marked A or B, which shall be calculated?
For safety reasons, according to the A calculation, the weight of the material can be calculated according to B to avoid the insufficient use time
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The specification of channel steel is expressed by the height of the waist (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means that the waist height is 100 mm, the width of the leg is 48 mm, and the thickness of the channel is 5.3 mm, or 10# channel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on. In general, according to the model a, B, C order, its thickness (or intensity) increased in turn
The type of channel is not calculated or selected according to the best principle when it is not marked "A" or "B":1) if it is the construction side, according to A model selection calculation, the most material, the lowest cost;2) if it is the owner, according to B model selection calculation, higher strength, greater safety factor.
