Attic flooring

We're hoping to use this space to store some infrequently used stuff (Christmas trees & decorations, camping gear).

The bottom of the main 'triangle' is about 2.4m and it's over 2m high, and over 6m long, so I feel it deserves investigating.

A quick google showed some warnings about not overloading if roof is held up by manufactured trusses (which is what I think I've got) as opposed to huge and hefty old-style beams.

I put some yellow-tongue flooring in a garden shed, and they were pretty heavy sheets, so ...

1) is there any recommended flooring for attics ?
2) is there any rule of thumb re: loading ?

Cheers,
Andrew

Modern ceiling structures are designed to support a static load of 10Kg per square meter
To put anything other than the ceiling lining itself on the framing your ceiling needs a total redsign of the structural members so that it can support the extra loads.

To some extent, it will depend on the age of the building, as code requirements have varied over time.

Best to engage a structural engineer or architect to analyze the capacity of what you have (or appear to have). He or she can establish confidence limitations, and/or advise on strengthening. Strengthening will be a lot easier, before any flooring is placed.

Another shed in the back yard is probably a safer option.
