Derived section properties

Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For H 300x305x15x15 the computed area agrees with the published value to better than 0.01% and I_x to 0.02%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, Z_x	1,420,227 mm³
Elastic modulus, Z_y	465,727 mm³
Plastic modulus, Z_px	1,595,834 mm³
Plastic modulus, Z_py	714,332 mm³
Radius of gyration, rx	126.4 mm
Radius of gyration, ry	73.0 mm

Z is the elastic modulus and Z_p the plastic modulus, following Japanese practice.
