Strength comes from within
The future way of building homes has been around for more than 50 years
Masonite Beams is the lightweight I-joist that combines low weight, high strength and long spans. The beam’s I-profile means that less material is used compared with solid structural timber. Maintaining the traditions of northern Sweden, we have developed a building systems for the future from our factory in Rundvik. When you choose Masonite Beams you get quality – strong, lightweight beams.


Masonite Beams offer pre-fabricated beams that make the building process simpler, reduce waste and provide high quality in industrial production. Our machines process to 0.2 mm precision. We adapt the beam according to preferences with, for example, hole cutting, precise and mitre cuts, reinforcements, eaves rafters, web insulation and filling. We package pre-fabricated beams precisely and individually and supply fittings adapted to the beam delivery.
We adapt your joist with holes in different sizes and shapes.
Choose from our eaves rafters in solid wood in various shapes and designs.
We produce web filling/end blocks in wood or particle board.
We supply both mitre-cut and straight studs and joists in one or more sections.
We have a wide range of fittings adapted for the I-joist.
We also offer web-insulated joists and studs.
A wide choice. You can use Masonite Beams’ products to build detached houses, extensions, apartment blocks and high-rise buildings. We offer you several ways to reduce your costs. The light weight makes them easy to handle, increasing the project’s efficiency. A construction worker, for example, can carry our products, which means that many work processes can be performed before you need a crane.
