Thread: Top Hat Installation Info

Hi Guys
I am a member of woodworkforums to mostly watch and learn on the wooden boat side of things but have ventured to the "dark side" of metalwork to ask for some advice.

I am building a freestanding 6m x5m Dutch Gable steel carport which I bought as a kit from a Gold Coast supplier whose advertising blurb said would include a full set of building instructions when they really meant here is a meagre set of engineering drawings and good luck. Nevertheless I completed the steel frame by myself to a pretty good standard and, as was always my intention, I contacted a professional roofer to have him hang the roof sheets and trim to get the best possible finish.

Long story short is that I can save some more money if I install the metal top hats (Topspan61) myself. My immediate problems are positioning (which I can probably work out from the plans even though no dimensions are given) and cutting mitres on the battens where the hips meet.

Is it just the same as woodwork - cut the 45 mitre and secure both ends independantly (two perpendicular sds) on the steel purlin ?

Thanks
bagman
