Parallel Flange Channels (MCP). Reproduced as printed in IS 808 Table 8 - Parallel Flange Channels.

Quote the mass when you order this section

IS 808 marks this designation with an asterisk: These heavier sections in each size are obtained from the same set of rolls as the lighter sections by spreading of the rolls. Therefore, while ordering these heavier sections, mass should be mentioned. More than one section is called MPC 300*, so the designation alone does not tell a supplier which one you want.

MPC 300* section properties

As printed in IS 808 Table 8 - Parallel Flange Channels. 300 mm deep, 92 mm wide. Units are shown on every row, because the two standards on this site use different ones for the radius of gyration.

What a length of MPC 300* weighs

Total weight is the mass per metre multiplied by the length and the number of pieces. Ten pieces of MPC 300* at six metres each is 41.5 × 6 × 10 = 2,490 kg. There is nothing else to it — the standard publishes the mass, so no one needs to compute it from the area.

You can check that mass against the area on this page: 52.8 cm² of steel at 7 850 kg/m³ is 41.45 kg/m. Every row in this dataset was checked that way, which is how the contradictions flagged on some of these pages were found.

Common questions about MPC 300*

What is the weight of MPC 300* per metre?

IS 808 : 2021 gives MPC 300* a mass of 41.5 kg per metre. Its printed cross-sectional area of 52.8 cm² agrees: 52.8 cm² of steel at 7 850 kg/m³ works out at 41.45 kg per metre.

How much does a 6 m length of MPC 300* weigh?

249.00 kg. Mass per metre times length: 41.5 × 6. Ten such pieces come to 2490 kg.

What are the dimensions of MPC 300*?

300 mm deep and 92 mm wide, with a 10 mm web and 13.6 mm flanges.

Why is there more than one MPC 300*?

IS 808 marks this designation with an asterisk, and its own footnote explains why: the heavier sections of a size come off the same rolls as the lighter ones, by spreading the rolls. The standard therefore says the mass should be mentioned when ordering — the designation alone does not identify which section you get.

Where these figures come from. IS 808 Table 8 - Parallel 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.
