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 200x204x12x12 the computed area agrees with the published value to better than 0.01% and I_x to 0.05%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, Z_x	498,230 mm³
Elastic modulus, Z_y	166,834 mm³
Plastic modulus, Z_px	565,497 mm³
Plastic modulus, Z_py	257,324 mm³
Radius of gyration, rx	83.5 mm
Radius of gyration, ry	48.8 mm

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