Unistrut channels are produced in a range of sizes from either 2.5mm or 1.5mm guage strip steel. The profile width and the inturned channel lip remain constant throughout the range, permitting the comprehensive selection of fittings and channel nuts to be used for all channels. Standard Unistrut channel ensures a high load carrying capacity whilst the thinner 1.5mm guage channel provides economical suppport for lighter loads, maintaining total flexibility in the design and construction of assemblies required for framing applications. Unistrut fittings are designed to be compatible with all Unistrut channels, providing the connection between channels to form a fully adjustable, rigid metal construction without welding or drilling.
