what size steel do i need for a 35ft rafter on a lean to?? or what is max i can go before it gets big steel ?? box profile roof
Should that be 254X146X31 @David.Pitch angle will make a difference as will potential for snow loading.
By way of example, I have a 25ft 10degree that is 354 x 146 x 31kg.
Fibre cement sheets.
10"x5.75" available at 31,37 and 43 kg per meterSo the old 10x6 !!!!!!
10 x 5 3/4Should that be 254X146X31 @David.
20ft bays ?We used 254x146x37 on a 31ft lean too @ 7.5 degree pitch.
