Lightweight Roof Beams

Composite beams are made from more than one material with one of the most common combinations being wood and plastic.

Lightweight roof beams.

In some instances either 6 8 or 10 c purlins doubled back to back can be used to as rafters as a substitute to structural steel beams. Since 2012 mlb have been the only independent manufacturer and supplier of the iconic metsec lightweight lattice beam design. The streamlined rectangular profile of colorbeam closely resembles the shape of traditional timber beams. Lightweight steel lattice beams were first introduced by metsec in the 1950 s and their inherent advantages very quickly established the product as the first choice for structurally sound cost effective construction.

The typical roof structure now consists of steel i beam rafters placed approximately 10 feet this varies depending on purlin size and other variables apart with either 4 6 8 or 10 lightweight steel purlins installed horizontally across the rafters. These lightweight steel frames are built using all the design principles that have resulted from the development of roof trusses. Lightweight steel lattice beams were first introduced by metsec in the 1950 s and their inherent advantages very quickly established the product as the first choice for structurally sound cost effective construction. The high cost of wood now means that lightweight steel roof frames are cheaper than wood.

A wood plastic composite beam will be lightweight and less prone to rotting warping or mold build up but such beams are not designed to carry a significant amount of load. Since 2012 mlb have been the only independent manufacturer and supplier of the iconic metsec lightweight lattice beam design.
