A cladding assembly comprises first and second cladding panels, each having top and bottom edge portions and a pair of lateral sides, and a corner connection element disposed to couple a pair of adjacent lateral sides of the first and second cladding panels together. The corner connection element includes top and bottom edge portions and a pair of lateral sides, wherein the corner connection element comprises a pair of female connectors disposed at its lateral sides and the pair of adjacent lateral sides of the first and second cladding panels comprises a pair of male connectors for mating with the female connectors, or wherein the corner connection element comprises a pair of male connectors disposed at its lateral sides and the pair of adjacent lateral sides of the first and second cladding panels comprises a pair of female connectors for mating with the male connectors of the corner connection element.

Cladding assembly and method of cladding posts

A filament-wound composite coupling for use in assembling a restrained joint between large diameter pipes with complementary retaining grooves, such as 16 inch or larger outer diameter polyvinyl chloride pipes. The coupling has first and second ends and ported retaining grooves associated with each end. Preferably, the coupling also includes O-ring seals and a pipe stop to index the pipes to be coupled. The composite coupling has a cylindrical composite body with a plurality of concentrically arranged layers of wound filaments in a thermoset plastic matrix. Each of the layers is characterized by a winding angle opposing the winding angle of the adjoining layers.
