Common questions about Sloping Flange Channels (MC)

How many sloping flange channels (mc) are there in IS 808 : 2021?

20, from MC 75 at 7.14 kg per metre to MC 400 at 50.1 kg per metre. They are printed in IS 808 Table 6 - Sloping Flange Channels.

Which is the lightest sloping flange channels (mc) in this table?

MC 75, at 7.14 kg per metre with a sectional area of 9.08 cm². The heaviest is MC 400 at 50.1 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. MC 75 at 7.14 kg/m, in 6 m lengths, ten of them, is 7.14 × 6 × 10 = 428 kg. The standard publishes the mass, so there is nothing to compute from the area.

Why are 2 rows in this table marked?

Because the standard contradicts itself on those rows: it prints both the sectional area and the mass per metre, so each is a check on the other, and on those rows the two disagree by more than rounding explains. Both figures are shown exactly as printed and neither is corrected — but you are told, so it can be checked before it reaches a tender.

Where these figures come from. IS 808 Table 6 - Sloping Flange Channels 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run against them, and the findings those checks produced — which rows disagree with themselves, which figures were superseded by amendment, and which could not be read — are QuickBOQ’s work, and so is this wording.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.
