Description

Kerto is a laminated veneer lumber (LVL) product used in a variety of applications including beams, joists, trusses, frames, roof, floor and wall elements, components of door and vehicle industry, concrete formwork and scaffold boards.

Kerto® is produced from rotary-peeled 3mm graded softwood veneers, which are then glued together to form a continuous 1.8 or 2.5 metre wide product. The 21mm to 90mm thick sheets are then further machined to the finished dimensions. The result is an engineered wood product that maintains the natural beauty of wood whilst being strong enough for most types of construction.

Kerto-Q is produced in a similar way to Kerto-S but with approximately 20% of its veneers laid crossways. Kerto-Q delivers exceptional dimensional stability and performs well where high compression strength is required.
