I plan to build a picnic table, 30” wide x 96” long. I want to use decking that is made with recycled plastic (Trex or equal). I will need to tie the boards together with battens. Anyone have any experience with this type of decking? such as; what material to use for the battens? What screws to use that will hold in this plastic material? I figured this material would stand up well outdoors unlike solid wood. The material I’m looking at is 5.4” wide and 1” thick, called “Choicedek” composite deck boards.

Hi MrRon—I’ve built several picnic tables, but never out of composite material. What I know about composite decking is that it sags. You will need extra support—more than just battens—to prevent the sag. See what the decking mfr. recommends—sometimes its 12” joist spacing, so plan the sub-structure accordingly.

Screws: any of the screws made for composite decking should be fine. Or, you can design a system that uses hidden fasteners, like screws from underneath. If you want it to last forever, use stainless steel

Thank you Jerry. I will add more battens and use SS screws.

Have your say...
