A set of components that can be used to construct a structurally sound dock are disclosed. The components can be extruded and the components are shaped such that interconnected components provide support for the other components thereby alleviating weak points due to welded only joints. A fascia channel provides additional strength by including structures that improve the vertical and horizontal strength of the fascia channel. HDPE plastic inserts and sheaves provide sound dampening for metal to metal contact points. Other components include a corner connector, a post system and a hinge system.
