Long Span Lattice Beams
One of the most unique benefits of our lattice beam system is their ability to span large distances. Spans of over 40 metres are achievable and our lattice beams span without the need for intermediate support columns.
In addition to the many benefits that our long span lattice beams offer, a typical lattice beam can weigh up to 50% less than its hot rolled counterpart and yet still achieve long spans.
Our lattice beams can allow architects much greater flexibility when working to optimise internal space. In addition to this, the space can also be optimised by passing services through the web of the lattice, rather than having to suspend them underneath causing a significant loss of headroom.
MLB’s lattice beams are designed bespoke for your project and can be fabricated to suit the following applications, <
Parallel Lattice Beam
Suitable for use with flat roofs or sloping roofs where the lattice beams can be laid to falls. They can also be used as long span purlins and are suitable for use with most external finishes from lightweight metal sheeting through to heavier constructions with tiles on battens or decking.
Curved Lattice Beam
Curved beams provide an aesthetically enhanced roof profile construction providing extra headroom over that afforded by the curved truss. When used with a standing seam roof this type of construction is easy to detail and install giving a very low maintenance roof.
Parallel Pitched Beam
Parallel pitched beams are suitable for all types of duo- pitch roof construction providing extra headroom over that afforded by the pitched truss. They can be used with most external finishes from lightweight metal sheeting through to heavier constructions with tiles on battens or decking.
Long span beams integral to innovative architecture
Trussed rafters are often an integral part of today’s modern structural design, allowing roof light to flood open plan internal spaces, or creating long span walkways or platforms.
To this end MLB Steel can customise the finish of long span lattice beams. All MLB lattice beams are supplied shot blasted and factory finished with a Zinc Phosphate primer as standard.
Other painted finishes, including any standard RAL colour, are available upon request. This feature is particularly important if it is desired to leave the lattice members exposed as part of a ‘feature’ internal roof structure.
A hot-dipped galvanised finish is also available. This is recommended for cold roofs and roofs with limited access or exposed locations.
