Reading GB notation
H beam: height × width × web × flange (mm). 200×100×5.5×8 = 21.7 kg/m. Channel/I beam # = height in cm; A/B/C = thin/standard/thick web variants.
Galvanized finish
Angles 3#–6.3#, channels 5#–14# and beams are available hot-dip galvanized — add roughly 3–6% to the black theoretical weight.
