kerto

Kerto is a brand of engineered wood products produced by Metsä Wood, a Finnish company. It refers to laminated veneer lumber (LVL), created by bonding several thin wood veneers with durable adhesives under heat and pressure to form a solid, straight, and uniform structural member.

Kerto LVL products are manufactured in a range of thicknesses and widths and can be produced in long lengths. The resulting material has high bending strength and stiffness relative to its weight, good dimensional stability, and predictable performance, enabling longer spans and lighter framing than solid sawn timber.

Applications include structural components such as beams, headers, columns, floor joists, roof timbers, and sometimes formwork and bracing. The material is valued for its strength, light weight, and uniform properties, which support efficient design and construction.

Manufacturing and standards: Kerto LVL is produced from softwood veneers, commonly spruce or pine, bonded with durable adhesives under controlled heat and pressure. Products undergo quality control and testing to meet relevant national and international standards for structural timber. The adhesives are selected to meet environmental and emissions requirements.

History and usage: the Kerto line originated with Finnforest in Finland and is now produced by Metsä Wood following corporate restructuring. It is widely used in Europe for residential, commercial, and industrial construction as part of the broader shift toward engineered wood products that offer sustainable and efficient building solutions.
