Cantilever Racking for Long, Heavy, and Oversized Materials

Cantilever has two capacity ratings. A single arm typically holds a few hundred pounds up to around 3,000 lbs on standard systems, with heavy structural arms rated higher and longer arms rated lower. The column itself carries the cumulative load of all its arms and runs much higher, up to roughly 20,000 lbs per side on heavy structural configurations. The right design depends on your heaviest individual product and how the loads stack up the column. For more on how rack capacity is calculated, see our pallet rack weight capacity guide. We engineer for your actual loads, not a generic spec.

Yes, with appropriate material and coating specifications. Outdoor cantilever systems require hot-dip galvanizing or industrial-grade powder coating for corrosion resistance, and anchoring designs that account for wind loads. We design outdoor systems to the same engineering standards as indoor installations.

Standard building permits apply, with the engineering level driven by your height and load capacity. Very tall or heavy-duty systems require stamped structural calculations. Our warehouse racking permits guide covers the full process. We coordinate all permitting as part of the installation and provide complete documentation.

Cantilever rack is purpose-built for long, bulky, and non-palletized materials that overhang or don't fit within standard pallet rack bays. Selective pallet rack is the better choice for palletized goods where you need direct access to every position. Many facilities use both: cantilever for lumber, pipe, and sheet goods, selective rack for palletized inventory in the same warehouse. For the full range of products cantilever handles beyond lumber, see our cantilever rack applications guide.

Cantilever systems are low-maintenance but should be checked periodically. Verify arm bolt connections are tight, inspect base plates and anchors for damage or loosening, confirm load placards are visible and accurate, and check columns for plumbness. We recommend an annual professional rack safety inspection to catch issues before they compound.

Cantilever is priced per arm level rather than per pallet position, because load widths vary too much for a per-position number to mean anything. New systems typically run $100 to $200 per arm level depending on arm length, capacity, and upright height, with single-sided (wall-mounted) systems costing less than double-sided freestanding runs. That range covers equipment and standard hardware, not installation, engineering, or permitting. For how cantilever compares to other systems on price, see our pallet racking cost guide. We quote against your actual arm lengths, spacing, and load requirements.

Roll-formed cantilever is made from lighter-gauge steel shaped by rollers. It costs less and suits light to medium-duty loads like retail lumber, pipe, and smaller bundles. Structural cantilever is built from hot-rolled structural steel, the same profiles used in building steel, which gives it far higher arm and column capacities, better resistance to forklift impact, and the durability for heavy industrial loads like steel bar stock, large-diameter pipe, and long structural members. As a rule, the heavier and longer your product and the more forklift traffic around the rack, the more structural earns its higher cost. We spec the construction type to your actual loads rather than defaulting to a catalog standard.
