I-Joist Manufacturer in Lithuania – Supplying Europe

IBJOIST is a Lithuanian manufacturer of engineered timber I-joist beams for construction projects across Europe. Our I-joists combine timber flanges with an OSB-3 web to provide lightweight structural solutions for roof structures, floor systems and timber frame construction.

By manufacturing directly in Lithuania, we supply I-joist beams to construction companies, timber frame manufacturers, builders and distributors seeking a reliable European manufacturing partner. We focus on consistent production quality, practical solutions and dimensions tailored to individual project requirements.

Engineered Timber I-Joists for Modern Construction

Timber I-joists are designed to provide an efficient alternative to conventional solid timber beams in suitable structural applications. Their distinctive I-shaped cross-section combines timber flanges with an OSB-3 web, creating a lightweight beam that is convenient to handle, transport and install.

Compared with conventional solid timber, engineered I-joists can offer improved dimensional stability and more consistent geometry. These characteristics make them suitable for a range of residential and other timber construction projects, subject to the relevant structural design requirements.

I-Joist Beams for Roofs and Floors

IBJOIST manufactures timber I-joists for a variety of building applications, including:

  • Roof structures: I-joists for rafters and other suitable roof framing applications.
  • Floor systems: Lightweight joists for timber floor construction.
  • Timber frame buildings: Engineered wood components for suitable structural applications in residential and other buildings.

The appropriate beam dimensions depend on the required span, loading conditions, support arrangements and structural design. Selecting the right specification helps ensure that the beams meet the requirements of each individual project.

Custom Lengths and Flexible Manufacturing

Every building project has its own structural requirements and dimensions. At IBJOIST, we manufacture I-joist beams in lengths of up to 12 metres, subject to production feasibility and the required specifications.

Our standard flange widths are 45, 70 and 90 mm, with different beam heights available to meet a range of project requirements.

As a direct I-joist manufacturer, we can discuss dimensions, quantities and cutting lengths before production. This allows customers to source beams tailored to their projects directly from our factory in Lithuania.

A Practical Alternative to Solid Timber

One of the main advantages of engineered timber I-joists is their dimensional stability. Their engineered construction helps reduce the risk of movement associated with natural variations in solid timber, although actual performance depends on the product specifications, moisture conditions, storage and installation.

The lightweight design can also simplify handling on site, while the efficient use of wood-based materials makes I-joists a practical option for modern timber construction.

As with any structural component, the suitability of an I-joist must be assessed according to the loads, spans and conditions specified in the building design.

A European I-Joist Supplier You Can Work With Directly

Based in Lithuania, IBJOIST supplies engineered timber beams to customers across Europe. By working directly with the manufacturer, customers can discuss their project requirements, available dimensions, order quantities and delivery arrangements without an unnecessary intermediary.

We aim to build long-term business relationships with construction companies, timber frame manufacturers, contractors and distributors looking for a dependable source of I-joist beams.

Whether you are sourcing roof joists for a residential development, floor joists for a timber building or I-joists for another suitable construction application, our team is ready to discuss your requirements.
