About us

We are Masonite Beams

Founded in 1974, Masonite Beams stands as one of Europe’s longest-running manufacturer of I-joists, proudly delivering innovative solutions to the construction industry for nearly five decades. Our advanced factory in Rundvik, northern Sweden, has the remarkable capacity to produce approximately 25 million meters of I-joists each year.

Our commitment to quality shines through in every product we offer. I-joists are significantly lighter than traditional structural timber, making them not only easier to handle but also minimizing warping and shrinkage. This is achieved through carefully selected timber and specialized board materials, giving our I-joists a high strength relative to their weight.

Collaboration with specialists and experts

We collaborate closely with specialists to develop a versatile building system tailored to various applications, including single-family homes, schools, extensions, and multi-family residences. Our I-joists are adaptable, serving as key components in floor structures, roofs, and wall systems.

At Masonite Beams, we are committed to quality and work continuously to improve resource efficiency across our operations. Our laboratory conducts rigorous testing to ensure that our products not only meet but exceed industry standards. Energy efficiency and development are at the core of our operations, guiding us from the sourcing of timber to the delivery of finished I-joists.
