how to attach composite deck to steel

TazPapa · 05-07-2009, 06:57 PM

I built a steel frame boat dock. I want to construct the deck with composite material. Are there self-tapping bolts or screws that will penetrate the composite material, drill the steel (1/8") material and sink the head into the composite?

Ayuh,... You might have to pre-drill the boards, but, Ya that's Real Doable....

The screws your referring to are called tapcons they have a drill bit like end.

I hope that the steel boat dock is Galvanized.

Aside from that, generally, when attaching wood/composite finish stock/framing/deck boards - to a steel frame, the process is to install (solidly through mechanical fastening) a wood sub-frame at 16" OC. - to the Steel frame.

In this case, you would use Pressure Treated stock for the subframe material.

Then, the finish wood/composite product/deck boards - are attached to that, using conventional SS deck screws.

Also: You need Stainless Steel fine-thread fasteners/lags/threaded bolts - to attach the PT wood subframe to the galv. steel framing.
