Metal connector plates.

A truss connector plate, or gang plate, is a kind of tie. Truss plates are light gauge metal plates used to connect prefabricated light frame wood trusses. They are produced by punching light gauge galvanized steel in order to have teeth on one side. The teeth allow the jointment of truss members together by being embedded into the lumber using a hydraulic press or a roller.

Nail plates are used to connect timber of the same thickness in the same plane. When used on trusses, they are pressed into the side of the timber using special hydraulic tools. As the plate is pressed in, the teeth are all driven into the wood fibers simultaneously, and the compression between adjacent teeth reduces the tendency to split.

A truss connector plate is manufactured from ASTM A653/A653M, A591, A792/A792M, or A167 structural quality steel and is protected with zinc or zinc-aluminum alloy coatings or their stainless steel equivalent. Metal connector plates have integral teeth and are manufactured to various sizes (that is, length and width) and thickness or gauges and are designed to laterally transmit loads in wood. They are also known as stud ties, metal connector plates, mending plates, or nail plates. However, not all types of nail plates are approved for use in trusses and other structurally critical placements. [1]


John Calvin Jureit invented the truss connector plate and patented it in 1955 and formed the company Gang-Nails, Inc.
