Dimensions in millimetres unless stated. Select a row to load its CAD files above.

Steel angle axes: y-y, z-z, u-u and v-v

y-y and z-z run parallel to the legs through the centroid, at distance c from the back; for an equal angle both give the same values. u-u and v-v are the principal axes at 45°, with the largest and smallest second moment of area.

Steel angle dimensions and properties

The section dimensions come from steel mill and stockholder catalogues. Area, mass per metre, second moments of area, section moduli and radii of gyration are calculated on the same section as the CAD file, root radii included, and checked against the catalogues to within 1 %. The STEP file is a 1,000 mm length; the DXF and DWG hold the section at 1:1.

A few sizes are left out because one of their properties did not match the catalogues within 1 %: the 45 × 45 series and three of the largest angles. An L 50 × 50 × 5, for comparison, weighs 3.77 kg/m and has its centroid 1.404 cm from the back of each leg.

Equal angles: common questions

How is an angle size written?: Leg × leg × thickness in millimetres: L 50 × 50 × 5 is an equal angle with 50 mm legs, 5 mm thick.
How much does an L 50 × 50 × 5 angle weigh?: 3.77 kg per metre, from an area of 4.803 cm².
