1. L/360 Deflection Criteria

• ALL PK Structures Mezzanines are designed in accordance with the L/360 deflection criteria, required by the National Building Codes: IBC, BOCA, UBC, SBC.

• L/360 establishes a 1” in 360” deflection in the horizontal beams.

2. Guardrail

• One Piece, factory welded design allows for quick installation.

• 42” high, two-rail design with 3” x 4” x ¼” Structural Angle Kickplate.

• Attaches to Deck surface easily with no interference from protruding columns.

• Designed to sustain lateral loads over 350 PSI. Which exceeds loading required by all National Building Codes.

3. Stairs

• Factory-welded stairs maximize strength and minimize installation time.

• 34” or 36” handrail on both sides complies with National Building Codes.

• 42” high guardrail available to comply with new IBC code.

• Rise and Run of stair design complies with all National Building Codes.

4. Lateral Loads

• All PK Structures Mezzanines are designed according to appropriate seismic requirements.

• All PK Structures Mezzanines are designed to exceed a lateral load of 2% of the total load of the mezzanine, exceeding a minimum 1000 lb. Lateral resistance.

• Increase rigidity of connections

• Allow safe, easy, quick installation

2. Eliminates the need for knee bracing, allowing more freedom for forklift travel,

Replacement of racks, shelving and office walls.

3. Eliminates the need for large, oversized baseplates that restrict aisle usage and

cause a trip hazard.

4. Utilize A325 structural bolts for all beam to column connections.

5. Fully Rigid Connection Available for areas with extreme seismic force exposure as required.
