Introducing the SK4000 Structural Tubular Pallet Rack

Feb 26, 2008

Steel King's new storage rack combines the load capacity of structural channel with the torsional resistance of tubular steel

For storage applications involving heavy loads, seismic locations, greater impact resistance, rack-supported buildings, and/or increased vertical heights such as automatic storage and retrieval systems (AS/RS), the new SK4000 Structural Tubular Pallet Rack by Steel King delivers by combining the load capacity of structural channel racks with the torsional strength of tubular steel.

Unlike conventional racks which offer load capacity in the 30,000 lbs. range, the SK4000 Structural Tubular Pallet Rack, with bolted beam connections, has the frame strength to support loads over 70,000 lbs.  This is more than enough rack capacity for even the heaviest die storage rack or auto part applications.  Thick structural tube steel increases the frames’ load-carrying capacity and resistance to seismic forces while enabling greater resistance to fork truck impact damage.

All SK4000 columns are tubular members of A-500 grade "B" steel with minimum tensile of 58,000 PSI and minimum yield of 46,000 PSI.  To meet the installation requirements, it's available in standard column sizes of 3” x 3”, 4” x 3” and 4” x 4” with thicknesses of 1/8” or 3/16”.  Tubular columns, along with the rigidity of an all welded upright frame, make it the perfect choice for rack-supported buildings and AS/RS.

For added strength and stability, its uprights incorporate fully welded, tubular steel for both horizontal and diagonal bracing.  Beams are securely fastened to uprights using heavy-duty grade 5 hardware.  Additionally, beam connection holes are drilled on the column's sides, not the corners, minimizing column strength loss.  Standard column punching on the storage rack provides users the flexibility to adjust beam elevations in 3" increments. 

Unique among racks, the SK4000 Structural Tubular Pallet Rack can be made to meet your exact preferences for adjustability and cleanliness. The columns may include holes for beam locations throughout the entire rack height, limited to just the locations used, or anything in between.

For maximum sanitation, with the limited connection hole option, a user can create a rack system with no exposed holes in the columns, making the SK4000 Structural Tubular Pallet Rack the perfect choice for industries in need of a more sanitary storage option, such as food and pharmaceutical facilities.  In addition to the closed tubular columns and bracing, all seamless welding and position drilled beam holes, its columns can be fitted with welded-on caps eliminating all potential gaps for internal contamination.  Tubular rectangle braces can also be rotated 45 degrees creating diamond shaped bracing, with no flat surfaces exposed for potential germ collection – creating the ultimate sanitary rack.

A highly durable, powder coat paint finish on the SK4000 Structural Tubular Pallet Rack offers better gloss, hardness and adhesion than typical enamel paints for greater resistance to fork truck impact, solvents and corrosion.  A choice of twelve standard colors allows color-coding the storage racks by use or for aesthetics.  An optional galvanized finish is also available to meet USDA requirements.
