Common questions about Angle Sections

How many angle sections are there in the Indian Standards?

198, across 4 tables — IS 808 Table 9 - Equal Leg Angles; IS 808 Table 10 - Unequal Leg Angles; IS 808 Table 11 - Angles; IS 808 Table 12 - Supplementary Unequal Leg Angles. They run from ∠ 20 × 20 × 3 at 0.9 kg per metre to ∠ 200 × 200 × 25 at 73.9 kg per metre.

Which Indian Standard covers angle sections?

IS 808 Table 9 - Equal Leg Angles; IS 808 Table 10 - Unequal Leg Angles; IS 808 Table 11 - Angles; IS 808 Table 12 - Supplementary Unequal Leg Angles. Every figure on this page is reproduced as printed there, and each table below carries the standard and table number it came from.

How is the weight of an angle calculated?

It is not calculated — the standard publishes it. Mass per metre is the cross-sectional area multiplied by the density of steel, 7 850 kg/m³, and both figures are printed, so each checks the other. That is how the contradictions flagged on some of these rows were found. For a length, multiply the mass per metre by the length and the count.

Where these figures come from. IS 808 Table 9 - Equal Leg Angles; IS 808 Table 10 - Unequal Leg Angles; IS 808 Table 11 - Angles; IS 808 Table 12 - Supplementary Unequal Leg Angles 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run against them, and the findings those checks produced — which rows disagree with themselves, which figures were superseded by amendment, and which could not be read — are QuickBOQ’s work, and so is this wording.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.
