02 KERTO® – ENGINEERED TO PERFORM

Kerto is a laminated veneer lumber (LVL) product used in all types of construction projects, from new buildings to renovation and repair. Kerto is incredibly strong and dimensionally stable, and it does not distort or shrink. It derives its high strength from the homogeneous bonded structure. Kerto is produced from 3 mm thick, rotary-peeled softwood veneers that are glued together to form a continuous sheet. The sheet is cut to length and sawn into beams, planks or panels in the sizes that customers require. Kerto products are CE marked and certified by VTT Technical Research Centre of...

KERTO-S CREATES LONG SPANS One of the notable features of Kerto S is that the wood grain runs longitudinally through all the layers. The finished panel is cross-cut and rip-sawn to order. Kerto S is normally supplied in the form of straight beams but it can also be specially cut and shaped as required. Kerto S combines excellent technical performance with ease of use. Its essential qualities include strength, dimensional precision and stability. It is the ideal choice for beams whenever long spans and minimal deflections are required. Kerto S beams are suitable for all roof shapes, also...

MAXIMUM SPAN FOR KERTO USED AS JOISTS AT 600MM SPACING IN RESIDENTIAL FLOORS Kerto assumed restrained against torsional buckling. Load 1.5kN live load and 0.75 dead load. Span is the design span between the centres of two supports. Calculation according to BS EN 1995-1 modifications factors are used for medium term and LVL KERTO S PERMISSIBLE UNIFORM LOADS kN/m The load combination as per BS EN 1990 domestic floors standard construction. Span is the design span between the centres of two supports. Calculation according to BS EN 1995-1 modifications factors are used for medium term and LVL.

STABILISES STRUCTURES Kerto Q is cross-bonded Kerto. This means that one-fifth of the veneers are glued crosswise. This structure improves the lateral bending strength and stiffness of the panel, thus increasing the shear strength. With cross-bonded veneers, there is an essential reduction in moisture-dependent variations across the width of the panel. Kerto Q comes in the same dimensions and lengths as Kerto S, except that its maximum thickness is 69 mm. Large sized Kerto Qis a popular material in floor and wall panels because it stabilizes the whole structure, and good fire resistance is...

Kerto can be further processed in many different ways according to its end-use and the customer's particular wishes. The further processing service is an integral part of the customer service and supply chain. TYPES OF FURTHER PROCESSING Further processing takes place at the production plant or at a service centre in a particular country, whichever is more competitive and economically • Sanding: optical or calibrating » Profiling of the beam edge, e.g, tonguing and grooving » Special sawing: both straight and tapered shapes • Gluing: re-gluingfor increased thicknesses » CNC machining:...
