C16 Timber Joists UC3u Treated Kiln Dried Regularised FSC 47 x 125mm (5x2)

C24 Graded Timber

C16 and C24 are strength grades; the higher the grade, the better the load bearing quality it has. C16 is normally the grade that is produced from faster grown UK timber. C24 is a premium product as the wood is slower grown and is also denser. Higher loads and longer spans can be achieved with the use of C24 grade timber often with a smaller cross section.

UC3u Treatment Class

Crafted from UC3u treated timber, these provide robust protection against rot and decay. Ideally suited for above-ground outdoor applications such as constructing pergolas and garden structures. UC3u is not recommended for a raised decking, as it is not treated for ground contact and moisture can travel, always use UC4 joists for decking joists. Alternatively, these are ideal for indoor applications such as internal structural joists and rafters.

Carcassing

A generic trade term which refers to the use of a species of timber. Spruce/Pine and Fir are used to form floors, walls, ceilings and roofs of properties for example.

Chain of Custody

All our timber has full chain of custody, meaning our timber is sourced responsibly.

Please note: Timber and stone are natural materials, and as such, variation in colour, texture, and natural markings is to be expected. We strive to represent our products as accurately as possible through imagery; however, colours and shades may appear differently depending on individual monitor settings such as brightness, temperature, and contrast. These variations are not considered defects.
