Cantilever Rack in Greater Nashville

Roll-formed cantilever uses bent sheet-steel components — lighter, less expensive, typically rated 500 to 1,500 lbs per arm pair. Structural cantilever uses hot-rolled I-beam and heavy tube steel, typically rated 1,500 to 4,000+ lbs per arm pair. Use roll-formed for lumber, light pipe, and packaged goods; use structural for steel bar, heavy pipe bundles, and steel service center inventory.

Yes. Because cantilever systems bolt together and anchor with standard base shoes, they can be disassembled, relocated, and reinstalled — including adjusting arm elevations up or down the column in set increments. This is a major operational advantage when product mix changes.

Usually, yes. Middle Tennessee is typically ASCE 7 Seismic Design Category B or C depending on site class, with higher values toward Clarksville and the New Madrid side of the state. For cantilever — especially tall or double-sided configurations — base-shoe sizing, anchor count, and bracing are checked against the site seismic values, so the anchor pattern is engineered rather than assumed. Every install we do includes sealed engineering by a Tennessee-licensed PE addressing this.

Arm length should support the load across at least two arms with appropriate overhang, typically no more than 25 percent of load length extending past the last arm. Standard arms run 24, 36, 48, 60, and 72 inches. For lumber and pipe, 48" is the common default; steel service centers typically run 60" to 72" for long bar stock.

Yes, and it is common. Arm elevations along a single column can be adjusted independently at 3-inch or 6-inch increments (depending on column hole pattern), allowing one bay to hold tall bundles at wide spacing and the next bay to hold closer-spaced short-length stock. This is a core advantage over fixed-beam pallet rack for long-load operations.

Single-sided against a wall is the simpler install and works when you have one aisle and limited floor depth. Double-sided freestanding doubles the linear arm-feet per column footprint but requires two aisles (one on each side). For most mid-to-large Greater Nashville lumber yards, plumbing distributors, and steel service centers, double-sided is the dominant pattern because the density gain pays back quickly.

Capacity is per arm pair and varies enormously by design: light roll-formed cantilever arms carry 500–2,000 lb each, while heavy structural arms for steel service centers run 5,000–20,000+ lb. Total column load and base design matter as much as the arms. Nashville Pallet Rack sizes cantilever from your actual load list and provides stamped capacity documentation.
