Questions about 3-point trusses
Which size suits my span?
The load table decides: in the data sheet of each type, find the row for your span and compare the permitted load with your load – as uniformly distributed load, centre point load or third-point load. Not sure? Send us span and loads, and we recommend the type.
When do I need the HD version?
The HD versions have a 48 × 3 mm chord tube instead of 50 × 2 mm and are designed for higher loads. Standard or HD: compare the two data sheets for your span – or ask us.
