UNARCO Structural Rack

System Highlights:

Structural Steel Pallet Racking can be used in any pallet rack application including:

  • Drive-In/Drive-Thru Rack
     
  • Push Back Rack
     
  • Carton Flow Shelving
     
  • Pallet Flow Rack
     
  • AS/RS Applications

Racking systems constructed of structural steel are all-welded design and are available in bolted connections or a hybrid rack with structural uprights and roll-formed beams.  This option is a cost-effective solution and is available with interchangeable teardrop punched uprights and roll-formed beams with automatic locking devices that snap into place.  This can save time and labor during installation.

The Structural Rack provides a long-term ROI on capital because of its strong and sturdy construction.  Protect your investment by adding a full line of Durability add-on accessories to protect against forklift  impact or warehouse storage abuse.

Description

Structural Rack Options

Structural racks are designed with high-strength, structural steel C-Channels for added toughness and rigidity.  UNARCO offers 3″ and 4″ upright posts with sturdy structural steel bracing. Heavy-duty structural beams range from 3″ to 6″ in height to meet the most demanding load criteria.

UNARCO also manufactures a 3″ structural rack with teardrop punching; this allows the addition of interchangeable roll-formed beams as an economic and efficient option.  This type of structural rack, known as a hybrid structural rack, is available with automatic locking devices in lieu of a bolted connection.

Structural pallet racks are designed to prevent damage from forklift abuse.  The posts and beams are constructed from structural steel and are much thicker than roll-formed posts, particularly at the corners which are the primary impact points.

The high-strength and durability of structural steel combined with UNARCO engineering and design can solve any project dilemma or increased rack capacity need and create a more efficient warehouse space.  Special structural rack designs, including high capacity Pick Modules or Automated Storage and Retrieval Systems (AS/RS Systems), are engineered in-house to assure project compatibility.

Applications for Drive-In/Drive-Thru racks as well asPush Back Rack and Pallet Flow Rack systems all gain extra durability with UNARCO structural steel designs.  When you combine the durability of structural steel with heavy-duty RhinoTrac Carton Flow, you have the most efficient and maintenance-free carton flow system available for ultra-high Pick Modules.

  • All capacities are expressed in pounds per pair of beams. Only gravity loading and the RMI required impact have been considered.
     
  • All values are based on a uniformly distributed load (i.e. each beam carries 50% of the load) and assume proper installation and no beam damage.
     
  • The deflection limit for all beams is the length divided by 180.
     
  • Structural beams that are longer than 108” require lateral ties.
     
  • Values in the table are for the beam bending only.
     
  • Please consult Springfield, Engineering for any shelf load over 10,000 lbs.
     
  • Capacities include 12.5% impact for two pallets side by side. For a three-pallet-wide shelf, the values should be multiplied by 0.95. For one pallet per shelf, the values should be multiplied by 0.90.
     
  • Capacity chart is based on current RMI specifications.
