SHALLOW CHANNEL PLAIN – Steel with a Minimum yield strength 280 N/mm. Beams are assumed to be simply supported.
Load and deflection are calculated using a safety factor of 1.6 and an allowable stress of 175 N/mm.
Results given are for Pre-galvanized steel, Hot dipped galvanized will reduce the stress due to the heat treatment and reduce the loading in the chart by a factor of approx 18%. Beam loads are calculated from the column face and effective length in BS5950.

DEEP CHANNEL SLOTTED – Steel with a Minimum yield strength 280 N/mm.
Beams are assumed to be simply supported.
Load and deflection are calculated using a safety factor of 1.6 and an allowable stress of 175 N/mm.
Results given are for Pre-galvanized steel, Hot dipped galvanized will reduce the stress due to the heat treatment and reduce the loading in the chart by a factor of approx. 18%.
Beam loads are calculated from the column face and effective length in BS5950.

SHALLOW BACK TO BACK CHANNEL SLOTTED – Reduce installation time – by eliminating drilling requirements
Lighter – making it easier to handle and install
