1 n Architectural Appearance n Full Framing-Width Stock Glulam n I-Joist and Conventional Depths

2 2 X-Beam: X-Beam is the building industry s first full framing-width stock glulam in architectural appearance. X-Beam eliminates the need to fill the 3" gaps that 3 " and 5 " beams create. For builders, this translates to lower installed costs and more efficient framing. X-Beam is available in 3 /2", 5 /2", 6 3 ", and 8 3 " widths, I-Joist compatible and conventional depths. Next-generation X-Beam has gained a reputation as the most adaptable and cost-effective engineered wood product in the market. Along with offering I-Joist compatibility, X-Beam has become the premier choice for short window and door headers due to its ease of installation and price advantages. Major hardware manufacturers like Simpson and USP support the X-Beam products with full lines of compatible hardware. Backed by 's signature customer support, X-Beam is the ideal glulam product for today's building marketplace. Uncompromised Strength: 24F-V4 X-Beam s greater width and increased wood volume translates to more load-carrying capacity (up to 2% for 3 /2" and 7% for 5 /2"). There s greater surface area for continuous and interior bearing, and holes can be drilled within liberal guidelines. Key Advantages Now that X-Beam has solved the sizing issue, the innovative glulam represents an all-purpose solution. Key advantages include cost-effectiveness, architectural appearance, lighter weight, greater strength, single-piece installation, compatibility with I-Joist and traditional depths, and wet-use adhesives. Available Net Widths: n Beams: 3 /2", 5 /2", 6 3 ", and 8 3 " n Columns: 3 /2" x 6", 5 /2" x 5 /2", 5 /2" x 6" I-Joist and Conventional Glulam Depths A full range of common depths means our glulam will do the job: n I-Joist Depths: 9 /2", 7 ", 4", 6" and 8" n Glulam Depths: 6" through 30" in /2" increments Ecological Benefits Made from renewable 2nd and 3rd generation forests, glulam was green before green was a buzzword. As an even better choice for today s progressive market, X-Beam is manufactured with wet-use adhesives that meet or exceed the most stringent global emission standards. X-Beam Guide - May 204

(2) Applicable service conditions = dry. (3) The tabulated allowable loads are based on simply axially loaded columns subjected to a maximum eccentricity of either /6 column width or /6 column depth, whichever is worse. For side loads, other eccentric end loads, or other combined axial and flexural loads, see 2005 NDS. (4) The column is assumed to be unbraced, except at the column ends, and the effective column length is equal to the actual column length. (5) Design properties for normal load duration and dry-use service conditions: Compression parallel to grain (Fc) = 2,300 psi for 4 or more lams, or,900 psi for 2 or 3 lams. Modulus of elasticity (E) =.9 x 0 6 psi Flexural stress when loaded parallel to wide faces of lamination (Fby) = 2,00 psi for 4 or more lams, or,850 psi for 3 lams. Flexural stress when loaded perpendicular to wide faces of lamination (Fbx) = 2,000 psi for 2 lams to 5 in. deep without special tension laminations. Volume factor for Fbx is in accordance with 2005 NDS. Size factor for Fby is (2/d) /9, where d is equal to the lamination width in inches. Axial Loads Allowable Axial Load Tables: Side loads and bracket loads are not permitted. End loads are limited to a maximum eccentricity of either /6 column width or /6 column depth. Axial Loads: Loads and load components applied along an axis in such a way that no bending or torsion moments are produced. Side & Bracket Loads: Not permitted with these tables. 0 X-Beam Guide - May 204

For concentrated load conditions, contact Technical Support. (2) Field holes should be drilled for access only (small diameter wires, conduit, cable and other lightweight materials) and not for load bearing hardware attachments unless designed specifically by the project engineer. Square and rectangular holes are not allowed. (3) These field drilled holes should meet the following guidelines: A. Hole size: The hole diameter should not exceed /2" or /0 the beam depth, whichever is smaller. B. Hole location: The hole should have a minimum clear distance, as measured from the edge of the hole to the nearest edge of the beam, of 4 hole diameters to the top or bottom of the beam and 8 hole diameters from the end of the beam. Otherwise as shown in the shaded area. C. Hole spacing: The minimum clear spacing between adjacent holes, as measured between the nearest edge of the holes, should be 8 hole diameters based on the largest diameter of any adjacent hole in the beam. D. Number of holes: The maximum number of holes should not exceed hole per every 5 feet of beam length. In other words, the maximum number of holes should not exceed 4 for a 20- foot long beam. The hole spacing limitation, as given above, should be satisfied separately. (4) For glulam members that have been over-sized, these guidelines may be relaxed based on an engineering analysis. (5) Holes in cantilevered beams require additional analysis, contact Technical Support. X-Beam Guide - May 204

Treated X-Beam : Our Douglas fir, architectural appearance X-beam is treated with Hi-Clear II a clear treatment that leaves the beam a light honey color while providing resistance against insect attack, decay, mold, and mildew. Beams Are Available in Common Sizes Widths: 3 /2" and 5 /2" Depths: 9 /2", 7 ", 4", 6" and 8" Custom Glulam: Our industry-leading glulam is available in custom sizes, curved shapes and in a variety of wood species that give our customers greater flexibility and the convenience of combining custom orders with other building materials. isdesign Software Created by Calculated Structured Designs, isdesign uses the powerful.net technology and takes all of the guesswork out of specifying and using glulam. This software allows users to easily enter the span and load conditions for a given project and automatically determine the best product for that application. Users can also calculate multiple spans, point loads, cantilevers, and other applications. isdesign is ideal for architects, designers, and builders and recognizes all United States building codes while offering printable design calculations and beam capacities. Visit our website for more information. X-Beam and Treated X-Beam are now included in the MiTek Sapphire Product Suite. Sapphire users can now design with X-Beam and Treated X-Beam.
