Plain metal belts are created by welding together two ends of a metal tape to form an endless belt. High-energy beam-welding techniques, pioneered in the space program, form a high-integrity butt weld that is extremely strong and smooth.

A Metrak© belt employs a V belt bonded to the inner circumference of the metal belt. This two-element belt, which Belt Technologies calls Metrak©, distributes tracking stresses on the V belt rather than on the metal belt, thus maximizing belt life in a forced tracking system.
