I am in the process of purchasing the timber for my house roof
The frame is up and the plans state mgp 12 190x45 on a skillion roof with spacing of 900 for battens and a 5 deg pitch and a span of 5metres
First of all finding mgp 12 is hard to get and the LVL stuff is expensive and it might be exposed to the rain so its not my first option
Could I use mgp10 or f5 190x45 merbau or any other suggestions or reduce the spacing to 600m for more options?
Is the above information any help
