Lightweight steel roof support structures this is all about to change.
Lightweight roof beams.
But unlike timber colorbeam won t twist warp or rot and doesn t need painting making it ideal for home improvements.
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.
Composite beams are made from more than one material with one of the most common combinations being wood and plastic.
These lightweight steel frames are built using all the design principles that have resulted from the development of roof trusses.
Colorbeam light structural roof beams give you the good looks of timber plus the strength and durability of steel with the advantage of a low maintenance finish.
The streamlined rectangular profile of colorbeam closely resembles the shape of traditional timber beams.
The high cost of wood now means that lightweight steel roof frames are cheaper than wood.
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.
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.
