To ensure that your deck has a long, trouble free life, it's important to use the right fixings used to fix the planks to the bearers. This choice can be influenced not only by the prevailing climatic conditions, the proximity to marine environments, but also the actual wood used.

Normally, standard iron nails should not be used on external decking as they can rapidly corrode in certain climatic conditions or close to marine environments and not only leave black stains around the nail holes, but can eventually corrode so extensively that they will simply snap. Remember that all wood will twist and warp to some extent so its important that wood planks are firmly fixed to the bearers at regular spaced intervals to keep the timber from moving.
