Floor Joists

We have a variety of types of floor joists to choose from to fit your build and budget.

Soft Wood


Marches can supply traditional timber floors that are manufactured from a range of C24 Grade Timbers. Soft-wood joists are ideal for smaller builds where relatively short spans are involved. 




I-joists (also known as I-beams) are structurally engineered wood product, which has incredible strength in relation to its size and weight. They are produced by reforming timber fibres using a range of advanced patented processes. This ensures a product with unrivalled consistancy and performance.


Laminated strand timber and Parallel strand timber can also be used for  beams, lintels, purlins and rim board.


I-Joists can also be used to build flat or pitched roofs.
