Nails or Screws when installing decking?

We would recommend that you always use a stainless steel fixings as this will be corrosion resistant to prevent rusting. Screw fixing is the best method, we never use nails in any of our projects due to the natural movement of timber outdoors in a UK environment. Screws will be more secure and the structure will last longer. If you are using the face fixings method (Screw straight through the board into the sub frame) it is good practise to pre-drill holes to prevent splitting particularly at the ends of the boards.
