All the material you require to build your deck

Joists:

This calculator works out the joists at 500mm centres and nails are added pick 47 x 100 or 47 x 150 both will do the job but 47 x 150 is recommended if you are raising the deck from ground level . If you want the decking raised pick the height from the drop down box, this height is from ground to top of the deck. Lengths of posts , postmix and fixings are added

Decking:

The decking is supplied in the lengths that suit your job , these are calculated as covering 150mm (145mm for the board and 5mm gap for expansion and contraction) , any decks over the 5.4m long that are required are given in 4.8m lengths so there is as little joins as possible. All screws are supplies.

Handrails:

Handrails are calculated with the newel posts at 2m centres. You will need to add one newel posts for every time there is a gap in your total length. Spindle are calculated with 100mm gap
