Common questions about Medium & Wide Flange Beams (MB, WB)

How many medium & wide flange beams (mb, wb) are there in IS 808 : 2021?

28, from MB 100 at 8.95 kg per metre to WB 600 at 145.06 kg per metre. They are printed in IS 808 Table 1 - Medium & Wide Flange Beams.

Which is the lightest medium & wide flange beams (mb, wb) in this table?

MB 100, at 8.95 kg per metre with a sectional area of 11.4 cm². The heaviest is WB 600 at 145.06 kg per metre.

How do I work out the weight of a length from this chart?

Multiply the mass per metre by the length and the number of pieces. MB 100 at 8.95 kg/m, in 6 m lengths, ten of them, is 8.95 × 6 × 10 = 537 kg. The standard publishes the mass, so there is nothing to compute from the area.

Where these figures come from. IS 808 Table 1 - Medium & Wide Flange Beams Section properties are facts published in the standards, and they are reproduced here as printed. Where a standard contradicts itself, both of its figures are shown and neither is corrected.

What is ours. The selection and arrangement of these tables, the checks run against them, and the findings those checks produced — which rows disagree with themselves, which figures were superseded by amendment, and which could not be read — are QuickBOQ’s work, and so is this wording. Quote the numbers freely; they belong to everyone. Copying the compilation and the commentary is a different thing, and we would rather you linked to it.
