Question:

What's the difference between 16# I-beam and 16A I-beam?

What's the difference between 16# I-beam and 16A I-beam?

Answer:

No. 16, said waist high waist thickness 16cm, if have different sizes, need to add a, B, C difference, but the standard table didn't see this type of 16a, more than 20 have a, B or C type difference.
16A is a kind of 16#, section of the same size of the steel is high are the same, but added the A, B and C show that these width or thickness is not the same, of course, attribute (section area, moment of inertia) are not the same.
No. 16 means waist high 16cm, if the waist thickness has different sizes, then need to add a, B, C to distinguish, but the standard specification and exterior did not see 16A this model, more than 20 of the A, B or C model difference
Due to the relatively high section size and narrow section of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves of the cross section is different greatly, which makes it have great limitations in its application. The use of I-beam shall be selected according to the requirements of the design drawings.
I-beam is also called steel girder (English name Universal Beam). It is a strip of steel with an I-shaped section. I-beam is made of ordinary I-beam and light i-beam. It is a section steel with an I-shaped section.
