Maximum Span Of Steel Roofing

1a steel beam span length this is the effective span length of the beam the distance from the centre of one end bearing to the centre of the other end bearing for example if the clear distance between supports is 3m and the beam has a minimum end bearing length of 0 1m at both ends you would work out the effective span length as follows.

Maximum span of steel roofing.

It often depends on the wideness thickness and the types of roofing materials the climate it has to withstand and many other factors. Maximum 1400mm maximum purlin spaces are not suitable in all scenarios.

For loads calculated based on asce 7 10 lrfd please refer to section 2 4 1 of asce 7 10 for the applicable load combinations using allowable stress design.

The load span table below is based on allowable stress design asd. Brit tile 333mm tile length maximum 666mm purlin centres. For heavier material such as gage steel the metal roof purlins spacing length could go up to 4 feet. You can order sheets cut to specific lengths ranging from 5 to 45 feet long although it is difficult to handle a panel longer than 16 feet.

Panels of corrugated metal roofing typically come in 6 foot lengths. When calculating how many panels you need remember that you have overlap the panels by 2 inches so a 6 foot length actually covers an area 5 foot 10 inches long. Span tables for flat roof joists to bs 5268 7 2 imposed loads of 0 75 kn m for maintenance and snow load are applicable where there is no permanent access no fixed ladder or staircase and most areas where the altitude does not exceed 100 metres refer to bs 6399 3. The component parts can be easily transported to site and assembled into beams the whole space deck being constructed at ground level before being hoisted into position on top of perimeter supports.

Minimum purlin size will vary according to span. 5 fasteners per sheet every second trough. The maximum span for pan fastened wall cladding is generally governed by temporary deflection under load rather than permanent deflection around the fastener.
