Allowable design stresses are based on covered dry conditions of use. 2. The tabulated flexural stresses are based on loads of a normal duration and a referenced depth of 12 inches. For other depths, the tabulated flexural stress must be adjusted by a depth factor adjustment of (12/d) For depths less than 3½ inches, use the value for 3½ inches. 3. The tabulated design stresses provided in this table are based on a normal duration. Loads of longer or shorter duration must be adjusted in accordance with the 2012, 2009, 2006 International Building Code, the , 2006 International Residential Building Code, as applicable. Duration of load factors must not be applied to Fc I and E. 4. The allowable bending stress increase for repetitive members must not exceed 4 percent. 5. The tabulated tension stress is based on a length of 55 inches (1397 mm). For lengths longer than 55 inches, tabulated tension stress must be adjustred by a factor of (55/L) The tabulated values for lengths shorter than 55 inches must not be increased. 6. The values in this column reflect the true MOE which is the shear-free modulus of elasticity. When calculating deflection, both bending and shear deformations must be included. Equations for various span and load conditions are available in engineering references. For example, the equation for a simple-supported beam under uniform load is: = 270wL 4 /Ebd wL 2 /Ebd where: = Deflection in inches (in), w = Uniform load in pounds per lineal foot (plf), L = Design span in feet (ft), b = Beam width in inches (in), d = Beam depth in inches (in), and E = Shear free modulus of elasticity in pounds per square inch (psi) Refer to ICC-ES Evaluation Report ESR-3633 For additional information regarding Kerto-S Laminated Veneer Lumber (LVL). HANDLING, STORAGE AND INSTALLATION GUIDELINES: Warning: Failure to apply good building practices regarding application, handling, storage and installation of this product can result in poor performance and/or unsafe structures. Kerto-S LVL must be properly installed and braced before any loads are applied to the structure. Kerto-S LVL is to be used in a dry, well ventilated environment. Kerto-S LVL is not to be used for unintended purposes such as ramps or planks. Handle Kerto-S LVL carefully to avoid damage. Store the product on stickers on a clean, level surface and keep it dry. Use appropriate personal protection equipment for handling and working with wood products; including but not limited to eye protection and gloves. 2 KERTO-S LAMINATED VENEER LUMBER PRODUCT GUIDE USA VERSION

Tables are for simple span beams (with a support at each end) and uniformly distributed loads. 2. Continuous lateral restraint must be provided at the top (compression) edge of the beam to prevent buckling. 3. For other span, load or restraint conditions, design the beam using Finnwood software, istruct software or other competent analysiss. 4. Lateral restraint is required at supports to prevent rotation of the beam. LOADS: 5. There are three sets of Load Tables: 100% for Floor Loads, 115% for Roof Loads (Snow), 125% for Roof Construction Loads (Non Snow). Refer to the NDS (National Design Specification for Wood Construction) Section for more information about load duration. 6. In order to satisfy both deflection and strength requirements for beam design, live load for floors, live or snow load for roofs as well as total load (live or snow + dead load) must be considered. 7. Uniform load tables in this product guide have values for Live (or Snow) load as well as Total load. The user must calculate both uniform load values in pounds per linear foot (PLF). 8. Additionally, two deflection limits are listed for Live (or Snow) loads; the value typically required by the building code and a more stringent or higher performance value. The user must verify the requirements for the application and decide the appropriate deflection value to use. 9. The self weight of the beam is allowed for in the loads shown. It is not necessary to add the self weight of the beam to the calculated total load. MULTIPLE PLIES: 10. Loads are for one ply (member) 1-3/4 thick. Multiply the loads: x 2 for 2 ply beams, x 3 for 3 ply beams, x 4 for 4 ply beams 11. Beam plies (members) must be adequately connected by nails, screws or bolts as specified in this product guide or by competent analysiss. 12. Two (2) or more 1-3/4 plies are recommended for depths greater than 14 inches. If a single 1-3/4 member deeper than 14 is used; pay particular attention to stability, lateral restraint and connections. Make sure these structural details are provided and properly installed ply beams require bolts or long screws which are specifically manufactured to connect all the plies of a multiple ply beam. 4 - ply beams must be top loaded or loaded equally from both faces. 14. Refer to the multiple ply connection information in this product guide for specific fastener information for connecting the plies. Note: Connection requirements depend on whether loads are applied equally to each ply (Typically when beam is top loaded). Or if loads are applied to one face of the multiple ply beam. For loads applied to one face; additional connections and lateral restraint may be required to avoid torsional loads/stresses in the beam. BEARINGS: 15. Make sure bearings are structurally adequate to carry the loads and are in compliance with building codes and regulations. 16. Bearing widths shown are required to support the maximum PLF loads shown. If less than maximum PLF load is applied to the beam, tabulated bearing widths may be reduced proportionally as follows: Total Load applied/total Load from table. Refer to examples on PLF tables. 17. This value may be conservative, specific analysis may produce a better result. KERTO-S LAMINATED VENEER LUMBER PRODUCT GUIDE USA VERSION 3

16 CERTIFIED RAW MATERIAL Everything we do involves sustainability from managing forests sustainably to upgrading the renewable raw material to high-quality products. Currently, 90% of the wood Metsä Wood uses comes from certified forests, mainly PEFC. Forest certification covers sustainability from safety at work to biodiversity. It secures future growth of forests, and indicates the sustainability of wood. Our chain of custody management systems enable us to monitor the origin and logistics chain of the wood we purchase throughout the entire value chain. Our network allows for efficient, reliable logistics. SOFTWARE Kerto-S LVL may be designed using Finnwood software.
