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 200x200x8x12 the computed area agrees with the published value to better than 0.01% and I_x to 0.09%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, Z_x	471,563 mm³
Elastic modulus, Z_y	160,153 mm³
Plastic modulus, Z_px	525,497 mm³
Plastic modulus, Z_py	243,818 mm³
Radius of gyration, rx	86.2 mm
Radius of gyration, ry	50.2 mm

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