Same legs. A different thickness.

One extra millimetre increases this angle’s theoretical mass by 18.6%. Specify both leg dimensions and thickness.

Drawn to the same scale within each pair. Dimensions in mm. Simplified geometry; root radii and flange slopes are omitted.

Sizes and weights by standard

Weights are theoretical, from nominal dimensions at 7.85 g/cm³: Actual delivered mass and billing basis must be confirmed with the quotation. Verified tables have been checked against the stated standard or catalogue source; Calculated values are nominal estimates, subject to the stated assumptions.

GOST 8509-93

Equal-leg angle, CIS

Verified

Size is leg × thickness in mm. Mass is computed from nominal dimensions at 7.85 g/cm³, as the standard states. Area shown where it was checked; the full range runs to 250×35 and is being completed.

Source: GOST 8509-93. Every row with an area passes area × 0.785 = kg/m.

Chinese equal angle (等边角钢)

Verified

Chinese material is common in Georgia, and this is the standard it arrives to. Designated by leg width in cm, e.g. ∠100×10. Surface area per metre is published here too, which is what you need for paint and galvanising quantities.

Source: GB/T 706-2016. Every row passes area × 0.785 = kg/m. The 250 mm block is withheld: the source's weight column is shifted one row against its own areas.Section properties

Theoretical and delivered weight

Multiply the nominal table weight by the ordered length or area to estimate theoretical mass. Delivered mass can vary with manufacturing tolerances. Confirm whether the quotation and invoice use theoretical or weighed mass.

Galvanised weight

Hot-dip galvanising coats every surface, so it adds more to light, thin sections than to heavy ones: roughly 1.5% on heavy plate, up to 8 to 10% on a light angle or thin tube. Compare galvanised to galvanised. Minimum coating per EN ISO 1461:

Steel thickness	Mean coatingµm	Mean coatingg/m² per side
over 6 mm	85	610
3 to 6 mm	70	505
1.5 to 3 mm	55	395
under 1.5 mm	45	325
