Particle board flooring - colour types?

[Scouse]

I'm just about up to the stage where I'm putting up my 'big shelf' (technically I can't call it a mezzanine) & I'm looking at 19mm particle board flooring.


There seems to be a few different colour tongues but I'm having trouble differentiating between them.


Bunnings have yellow & green:
3600 x 900mm x 19mm Structaflor Yellow Tongue Particle Board Flooring I/N 0460721 | Bunnings Warehouse (http://www.bunnings.com.au/3600-x-900mm-x-19mm-structaflor-yellow-tongue-particle-board-flooring_p0460721)


3600 x 900 x 19mm Green Tongue Particle Board Flooring I/N 0460014 | Bunnings Warehouse (http://www.bunnings.com.au/3600-x-900-x-19mm-green-tongue-particle-board-flooring_p0460014)


Masters have the same yellow as Bunnings but also have orange:

They're all a similar price so would I be right in assuming they're just colours used by different manufacturers for what is essentially the same product?

Bunnings 19mm yellow and green are for 450mm spaced joists, the yellow standard and green is moisture resistant. 22mm is for 600mm joists.

Thanks Simon, all the 19mm boards seem to be for 450mm spacings but I wonder why 'green' is cheaper than 'yellow' if it's a better product.


From what I can tell, the green is a Laminex product whereas the yellow is from Carter Colt Harvey.


So far I'm leaning towards the green for $$ & a Google search has found a builder who prefers it over yellow:

The Bunnings price for green tongue is the best I have found so far, even including eBay.

If it is protected (from external weather) and you are using 450 centres, then go with the best $$.

Yes, it's all inside my shed. Looks like I'll be buying about 30 sheets of green tongue shortly :).
