Cantilever Racking Systems in Utah
Rocky Mountain Warehouse Solutions designs, supplies, and installs cantilever racking systems for Utah businesses that store lumber, pipe, steel bar, furniture, sheet goods, and other long or irregularly shaped materials. Our systems provide unobstructed front access for easy loading and retrieval.
What Is Cantilever Racking?
Cantilever racking is a specialized storage system designed specifically for long, bulky, or irregularly shaped materials that cannot be stored on standard pallet racking. Unlike conventional racking, cantilever systems have no front column obstruction - horizontal arms extend from a central column, creating completely open bays that allow forklifts and cranes to load and retrieve materials from any position along the length of the arm.
This design makes cantilever racking the preferred solution for lumber yards, steel service centers, pipe and tube distributors, furniture warehouses, and building materials operations throughout Utah.
Single-Sided vs. Double-Sided Cantilever
Single-Sided Cantilever
Arms extend from one side of the column only. Typically mounted against a wall to maximize floor space utilization. Ideal for perimeter storage in lumber yards and manufacturing facilities.
Double-Sided Cantilever
Arms extend from both sides of the column. Freestanding in the middle of the floor with access from both sides. Provides the highest storage density per column for open-floor applications.

Relationship to Pallet Racking
Many Utah facilities use cantilever racking alongside pallet racking - pallet racking for boxed or palletized inventory and cantilever racking for long materials. Our warehouse design team can create an integrated layout that accommodates both storage types efficiently.
Sizing a Cantilever System: The Math That Matters
Cantilever specification goes wrong in a predictable place. Arm capacity and upright capacity are separate ratings, and satisfying one does not satisfy the other. An upright rated at 12,000 lbs total does not support six arms each rated at 4,000 lbs, because the column rating is the ceiling for everything hung on it, and that rating falls as arm length increases: a longer arm applies more bending moment at the connection.
Arm capacity itself is published at a specific load position, normally assuming a uniformly distributed load rather than a point load near the arm tip. A concentrated load at the end of an arm can exceed the rated moment even when total weight sits well under the published figure. That single misunderstanding accounts for most of the overloaded cantilever we are called out to inspect.
Arm spacing follows material deflection, not convenience. Material should span a minimum of three arms so the load distributes and the system cannot tip or rack, which means spacing gets set from the shortest material you intend to store, not the longest. Flexible stock such as thin-wall tube, small-diameter pipe, or long trim may need four or more arms to prevent sag between supports. Base depth governs stability: a taller upright carrying longer arms needs a deeper base to resist overturning.
Seismic Anchoring for Cantilever in Utah
Cantilever is more sensitive to seismic design than selective pallet racking, and the reason is geometric rather than regulatory. The load sits out on an arm rather than between two uprights, so the overturning moment concentrates in the base plate and its anchors instead of distributing through a bay. In the higher seismic design categories common along the Wasatch Front, that drives deeper bases, engineered anchor patterns, and in taller runs additional bracing.
Anchor selection depends on the slab rather than the rack. Pull-out values are a function of concrete depth, compressive strength, and distance to joints and slab edges, which is why an older building on Salt Lake City's west side can require a different base plate design than a new tilt-up shell a few miles away. We assess the floor before finalizing the base design rather than after, and we provide stamped drawings and anchor calculations where the building department's review calls for them.
Whether a permit is required is set by your local building department rather than by the state, and thresholds differ between jurisdictions along the Front. We confirm requirements with the authority having jurisdiction during layout, not after the steel arrives.
Outdoor and Yard Cantilever
Outdoor cantilever is standard practice for Utah lumber yards, building materials distributors, and pipe and steel suppliers, and it changes two things in the specification. Finish comes first: hot-dip galvanizing is the appropriate choice for anything in the yard or in an unheated building, and it costs considerably less specified at fabrication than remediated after corrosion appears at the connections. Wind loading then enters the calculation alongside seismic, which affects base depth and anchor design on taller freestanding runs.
Drainage and grade matter more than owners expect. A yard that ponds will corrode base plates from below, and a base sitting on uneven grade transfers load unevenly into the anchors. We look at the surface the system will stand on before quoting it.
Frequently Asked Questions
How much does cantilever racking cost?
Cantilever pricing is driven by duty rating far more than by size. Light-duty roll-formed systems are the least expensive per linear foot of storage; heavy structural systems with long arms and deep bases can cost several times as much for the same footprint. The variables that move a quote most are arm capacity, arm length, upright height, base depth, single or double-sided configuration, and whether the system needs galvanizing for outdoor use or engineered seismic anchorage. Send us the longest and heaviest items you need to store and we will return a configured quote with the capacity math shown.
How do I calculate the cantilever capacity I need?
Start with the heaviest single load that will rest on one arm, then confirm the total weight hanging on one upright across all arm levels. Those are two separate checks. Arm capacity must exceed your heaviest per-arm load with the load distributed the way you will actually store it, and upright capacity must exceed the sum of all arms on that column. Published arm ratings assume a uniformly distributed load, so concentrated point loads near the arm tip need to be de-rated.
Does cantilever racking need to be anchored or permitted in Utah?
Cantilever is anchored to the slab in essentially all commercial installations, and in the seismic design categories common along the Wasatch Front that anchorage is an engineered requirement rather than a precaution. Anchor selection depends on slab thickness, concrete strength, and distance to joints and edges, so the floor is assessed before the base plate design is finalized. Permit requirements are set by your local building department rather than the state, and we confirm them with the authority having jurisdiction during layout.
How much does cantilever racking cost in Utah?
Cantilever racking typically costs $150-$400 per arm position installed, depending on capacity and height. A complete system for a lumber yard or steel service center commonly runs $5,000-$30,000 depending on size and configuration. Contact us for a free quote.
Can cantilever racking be used outdoors?
Yes. Hot-dip galvanized cantilever racking is available for outdoor applications. Utah's climate - with cold winters, hot summers, and occasional high winds - requires appropriate coatings and anchor specifications for outdoor installations.
What is the maximum height for cantilever racking?
Standard cantilever columns reach 20-30 feet. Taller systems are available for high-bay applications. Heights above 20 feet typically require engineering review and building permits in Utah jurisdictions.
