Hatman pretty much sums it up, but I've found it's either 12mm, 15mm or 18mm that you'll find in places like Bunnings. 15mm is fine providing your supporting structure is solid. If you want to minimise costs - then go with this option. It also depends on what angle you're talking about. Obviously the less steep - the less you need to really worry about thickness of board (generally speaking). We've used in the past 12mm for 15 degree (overhanging) - but with very good supporting structure behind it. If you're building a steep (45 degs or steeper) board and it's using 8x4 sheets - then you'll definitely want 17 or 18mm. We've got 17mm and 18mm at an angle of 70 and 55 degrees - and it doesn't flex at all - even when 90kg+ users pull down on it (we're all cake-eaters here).
