Ill be hopefully building a garage in the late spring early summer and ill be using attic or scissor trusses split in the centre with raised collar trusses enough so i can get a car lift in. I will be bracing as recommended for sch trusses however i would also want to install galvanised bracing on the outside in the opposite direction for better strength. I worked on roofs in OZ and we used galvanised roll instead of timber. I cant seem to find galvanised band more than 10m lengths. Does anyone know where i could buy this in the UK or even in Ireland.
The trusses will be spaced at 600mm spacing, one velux in between the rafters and installing 600mm x 300mm slates double lapped.
Ive been reading that for 600x300mm slates, 13 should cover a mtr sq however when im doing my calculations im getting more.
If my rafter length is 5.3m long to the ridge with 50mm over hang into the gutter. Think its a 181mm gage which works out at 28 battens. 10.5m length the garage. 10.5 divide by 303mm = 34.6. 35 slates long x 28 slates hgh = 952 slates one side.
10.5 x 5.3 = 55.65sq area. Round the slates of to 1000 and divide that by 55.6 is 18 a square meter. 5 extra per sq meter im getting. My measurements could be wrong. Xmass eve day drinks so forgive me if im wrong haha
