Help: how can I sample steel beams?
I-beam sampling is similar to steel reinforcement sampling:Randomly selected one or a plurality of sampling locations and sampling standard, steel, 50Cm after the number of interception head, pull a size of 40Cm and 35Cm, to cut a four molecular beam interception.
Randomly extract one or more of the root, cut down a paragraph, how much you need to cut the amount of steel on the head, 50cm is not countless
Cold is generally two times the thickness, tensile tensile and bending no specific requirements, the size of 450mm and 350mm, the sampling method can be used to blow out the slightly larger cutting requirements size, and then use the milling machine, cutting will affect regional removal.
The position of sampling and sampling reinforced standards like 50Cm after the number of interception head, pull a size of 40Cm and 35Cm, to cut a four molecular beam interception.
