Bay Poles: Calculations

Calculating imposed weights:

Measure the areas of building to be supported (DEAD LOAD) in square meters e.g. area of roof, walls, floor etc.
Check joist line, some end in the bay, which will potentially mean extra weight especially if supporting imposed loads.
Multiply these areas by the weight of the materials and add together.

Typical weights of materials

Floors: 220 kg per sq.m
Roof loading: 250kg per sq.m
Rendering or tile hung stud work: 100kg per sq.m
Single Wall Brickwork: 225kg per sq.m
Double Wall Brickwork: 450kg per sq.m

Add extra for upstairs window frames and glass, snow, other imposed weights and wind, all of which vary from site to site. Do not underestimate values.

Divide the sum (Max possible imposed weight) by the number of poles requires on the bottom bay, thus giving you the load on each bay pole.

The next step is to choose the right pole for the load. All poles have different ratings depending on pole material, length, diameter and wall thickness.

All of our Poles are load certificated.
