Galvanized Steel Truss Frames.  Manufactured using the highest quality 1-1/2" x 3/16" angle iron and 1/2" round bar, ensuring your dock stands the test of time.  All frames are hot-dipped galvanized to resist corrosion and pre-punched to allow the bolting together of additional frames to create a wider or longer dock system.  Frames are 3’ or 4’ wide and available in 10' or 20' lengths, with a standard height of 12".
