We offer jobsite delivery service to all of Ohio, Indiana, Michigan, Kentucky, Eastern Illinois and parts of West Virginia. Our staff of professional engineered wood product specialists are capable of designing floors and roofs for both residential and commercial projects.

Engineered for Quality

With the added performance and durability of engineered wood, Gorilla Lam LVL is perfectly suited to spans bearing heavy loads and multi-span applications. The normal problems associated with lumber like dimensional stability, cupping, warping, twisting and checking, are not a problem for LVL.

LVL utilizes a recipe of kiln dried, sonically-graded veneer to achieve consistent quality and performance.

Gorilla Lam LVL is made from sonically tested and graded Douglas fir veneer. Douglas fir is a closed cell structure vs. Southern Yellow pine, which is open cell. Douglas fir means our product is more stable and consistent than SYP LVL products. Our products’ higher tensile strength means better performance on the job. Gorilla Lam LVL is longer, stronger, straighter and more durable than dimensional lumber and less likely to warp, split or twist.

Gorilla Lam LVL can be used anywhere traditional lumber is used and more. LVL is a greener choice utilizing fiber from smaller trees allowing for quicker regrowth and sustainability.

General notes for this product guide:1. All tables assume dry conditions. Calculations are based on NDS and IBC and ICC-ESR#2913.2. Lateral support of the compression edge of all beams must be provided at 24” on center.3. Application tables include live load reductions applied in accordance with 2012 IBC.4. Tables apply to dead, floor live, roof live and snow loads. Lateral loads must be considered by the building designer.5. This design manual is intended to be used for preliminary design purposes. A complete structural analysis should be performed by a design professional.6. Beams that are 1-3/4” x 16” and deeper require multiple plies.

Allowable Floor Loads

Notes: 1. Live Load L/360 = Maximum live load - limits deflection to L/360.2. Total Load = Maximum total load - limits deflection to L/240.3. End/Int. Bearing = The required minimum end bearing (inches) for simple or multiple span beams and minimum interior bearing (inches) for multiple span beams based on the plate bearing stress of 565 psi.4. To size a beam, you should check both the live load and total load. The beam must work in both rows. When there is no live load, total load will control, unless floor live load deflections other than L/360 are checked.5. To size a beam for a span not shown, use values for the next larger span shown (example: for 9’ span, use values for a 10’ span).6. With floor live load deflection limits of L/480 or L/600, multiply the value in the floor live load row by .75 for L/480 and .60 for L/600.7. 1-3/4” beams with depths greater than 14” must only be used in multiple-ply applications. 8. For 5-1/4” beams, use the 1-3/4”table and multiply by 3 and for 7” beams multiply by 4.

Gorilla Lam Features

Why Gorilla Lam?• 2.0E: Among the highest rating available • 3100 Fb: Among the highest rating available• Manufactured with Douglas fir (most of the competition uses Southern Yellow Pine)

• Douglas fir is a more stable species • Less likely to cup • Lighter than SYP

• Many size options (1½”, 1¾”, 3½” and 5¼” thicknesses available)

Clear SealerAll Gorilla Lam LVL is fully sealed with a factory applied, industry-leading premium grade sealer. The sealer repels water absorption and improves durability during typical distribution yard and jobsite storage conditions.

FSC® CertificationGorilla Lam LVL products are available with chain of custody certification (FSC). Builders who utilize products manufactured from forests certified by FSC, with an intact chain of custody, can qualify for points in the US Green Building Council’s LEED system, a third-party certification program and benchmark for the design, construction, and operation of high-performance green buildings.

Notes:1. Minimum required bearing length is 1½" for end bearing and 3" for intermediate bearing.2. Bearing across full width of beam or header is required.3. Table is based on moisture content less than 16% for the LVL and not exceeding 19% for the Douglas Fir-Larch.4. Confirmation of structural adequacy of supporting member is required.5. LVL beams and headers must be restrained against rotation at end and supports.6. When LVL rests on steel or in a hanger, use bearing lengths shown in table. 7. No reduction in bearing (i.e., no increase in bearing stress Fc┴) is allowed for duration of load.8. For non-conforming situations, use sizing software or contact a Gorilla Lam technical representative.

NOTES:1. All fasteners must meet the minimum requirements in the table above. Side-loaded multiple-ply members must meet the minimum fastening and

side-loading capacity requirements given on page 17.2. Minimum fastening requirements for depths less than 7¼” require special consideration. Please contact a Gorilla Lam technical representative.3. Three general rules for staggering or offsetting for a certain fastener schedule: (1) if staggering or offsetting is not referenced, then none is

required; (2) if staggering is referenced, then fasteners installed in adjacent rows on the front side are to be staggered up to one-half the o.c.spacing, but maintaining the fastener clearances above; and (3) if “ES” is referenced, then the fastener schedule must be repeated on each side,with the fasteners on the back side offset up to one-half the o.c. spacing of the front side (whether or not it is staggered).

General Notes:1. Confirm the adequacy of the beam (depth and thickness) for carrying the designated load.2. Stress level for nail, bolt and screw values is 100%. Increases of 15% for snow loaded roof conditions or 25% for non-snow roof conditions are permitted.3. Top and bottom rows of fasteners should be as shown in the fastener clearances detail. For staggered fastening patterns, the maximum end distance applies to all rows.4. All fasteners must have the length fully embedded, but must not be over-driven, countersunk, or over-tightened.5. Bolt holes are to be 1⁄32” to 1⁄16” diameter larger than the bolts. Bolts must meet or exceed ASTM A 307 or SAE J42” Grades 1 or 2. Every bolt must extend through the full thickness of the member. Use washers not less than a standard cut washer under the head and nut meeting ANSI B18.22.1.6. 7” wide beams should only be side-loaded when loads are applied to both sides, when the lesser side load plf is at least 25% of the opposite side, or when the beam is otherwise restrained to minimize rotation.7. For beam depths < 7¼” , the maximum beam thickness must not exceed the beam depth and all fasteners must be staggered up to one-half the required o.c. spacing. For depths ≥7¼”, the maximum beam thickness is 7”.8. Fastening recommendations are based on the 2005 & 2012 National Design Specification for Wood Construction (NDS) or fastener manufacturer’s design information.9. SDS structural screws are produced by Simpson Strong-Tie Company, Inc., WS structural screws are produced by United Steel Products Company, and TrussLok structural screws are produced by FastenMaster-OMG, Inc. Structural screws must be installed per manufacturer’s recommendations.

2.0E ES LVL Top-Loaded DefinitionFor required multiple-ply member fastening, only conditions where the loading is applied evenly across the top of all plies shall be considered “top-loaded.” All other conditions must be fastened using the side-loaded recommendations on page 17. All top-loaded multiple-ply LVL members must meet the minimum fastener requirements and required fastener spacing shown above.

2.0E LVL Side-Loaded DefinitionConditions where the loading is not applied evenly across the top of all plies, where multiple-ply member fastening is used, shall be considered side-loaded. All side-loaded multiple-ply members must meet the minimum fastener requirements on page 16 and the loading capacity requirements below.

Maximum Uniform Load Applied to Either or Both Outside Plies (PLF) (Refer to General Notes on page 16.) • Numbers in the table indicate load in pounds per lineal foot which may be applied to either side (except as shown in note 6 on page 16), based solely on the connection. • Framing members must be attached with approved metal hangers. Refer to manufacturer specifications. • This table applies to uniform loading only. Concentrated (point) side loads may require additional consideration.

Notes:1. “ES” indicates fasteners must be installed from each side of the beam with the given fastening schedule. Stagger fasteners on opposite side of beam by up to one-half the required fastener on-center spacing.2. For nails, tabulated values may be multiplied by 2.0 for 6” o.c. spacing and by 3.0 for 4” o.c. spacing. For bolts, tabulated values for 24” o.c. may be multiplied by 2.0 for 12” o.c. spacing. For structural screws, tabulated values for 24” o.c. may be multiplied by 2.0 for 12” o.c. spacing, by 4.0 for 6” o.c. spacing and by 6.0 for 4” o.c. spacing.3. For 3 rows of fasteners, multiply tabulated values for 2 rows by 1.5. Center and stagger middle row by one-half the required o.c. spacing for depths less than 11¼”.4. Do not use fastener schedule if fastener clearances, required staggering and offsetting, or required fastening cannot be met. Consult technical representative for other options.
