Wood Beam To Steel Beam Conversion Chart. Calculate steel beam span length. The steel span length is essentially the distance from the centre of one end bearing to the other.

For example, if the exact distance between steel support beams is 4 metres, with an end bearing length of 0.1m, the span length would be 4.1m. Calculate steel beam span length. The steel span length is essentially the distance from the centre of one end bearing to the other.
