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-S is produced so that all its veneers are laid in the same direction, delivering a product perfect for beams whatever the specification and for achieving long spans with minimal deflection.
