Cantilever Rack in O'Fallon, MO
Fixtures, extrusions, and long packaged components near Highway K have outgrown improvised floor storage. Standard bays hold the boxed stock well but leave long pieces spanning several openings and complicating retrieval.
Cantilever rack provides an open loading face for long material on arms projecting from columns. Bundle length alone does not set support spacing: stiffness, weight distribution, arm length, and the handling movement all matter. We compare single-sided and double-sided runs against your load families, available approach room, and the usable height of the building. Match arm support to deflection and handling clearance, not merely overall bundle length. Start with your building drawing and current load information so the proposal addresses the immediate bottleneck rather than selling capacity you cannot use.
Why O'Fallon Warehouses Work With Us
Planning around WingHaven, Technology Drive, and the Highway K corridor starts with how the local operation handles material, not with a standard rack diagram. Fulfillment, medical supply, electronics, and light assembly operations around Technology Drive often need more pick locations before they need more total pallet storage. An expansion should preserve order access and packing space. The right layout treats reserve stock and active picking as separate demands on the same building.
For this project, the central decision is straightforward: match arm support to deflection and handling clearance, not merely overall bundle length. Cantilever warehouse racking should support material at the right points without asking the operator to twist a long load through a tight approach. We check arm ratings, column and base capacity, end overhang, and restraint for round stock. Different products may need different arm spacings instead of one nominal configuration across the entire row.
As a division of Warehouse Equipment & Supplies Co., St. Louis Pallet Racks gives you a single point of contact for the free warehouse consultation, layout revisions, component questions, and installation planning. We explain what is included, identify unresolved measurements, and keep changes visible in an itemized quote. If your operating priorities change, the drawing is reviewed before material is released rather than leaving your team to work around a surprise.

How Cantilever Rack Works
Arms with nothing in front of them, built for lumber, pipe, and anything a pallet can't hold.
Columns and anchored bases
Upright columns sit on bases anchored to the floor. Base depth is set by load and arm length so the run stays stable even under an off-center pick.
Arms at adjustable heights
Arms bolt or pin into the column at set increments and move as your product mix changes. Straight arms suit boxed goods; inclined arms with a lip hold round or loose stock in place.
Column spacing against sag
Spacing between columns is set so bundles don't sag between arms. A common starting rule places arms about half the load length apart, with the ends overhanging evenly.
Single-sided or double-sided
Single-sided runs go against a wall. Double-sided runs stand in open floor and load from both faces, doubling capacity per base without doubling the footprint.
What Your Cantilever Rack Project Includes
The layout also follows the longest bundle through its complete approach and retrieval movement. We reserve the space needed to turn and place it without obstructing neighboring pallet rows or the receiving route. Material families with different stiffness may receive separate support spacing. The approved drawing and itemized quote show those choices so arm quantity, capacity, and handling room can be reviewed together before purchase.
Cantilever specification starts and ends with the load. We collect bundle dimensions, weight per bundle, and how material is handled - forklift forks, a side loader, or by hand off a cart - because that determines arm length, arm capacity, and how much clearance each level needs.
From there we set column height and spacing, choose straight or inclined arms, and decide whether lips are needed to keep round stock from rolling. Single-sided runs get positioned along a wall; double-sided runs get aisle dimensions matched to whatever's moving material in and out.
The quote itemizes columns, bases, arms, bracing, and anchors, with a CAD drawing showing the run, arm levels, and rated capacities per arm. Installation partners anchor bases, plumb columns, brace the run, and set arm elevations to the drawing.
The result is arms you can reposition as inventory changes, capacity ratings for every level, and the floor space that long material used to occupy.
What We Need to Plan It
- What are the dimensions of the product being stored, length included?
- What's the typical weight per bundle?
- Straight arms or inclined arms - do you need lips to hold round stock?
- Single-sided along a wall, or double-sided in open floor?
- What's the clear height and the reach of your handling equipment?
Where This Service Fits
- Lumber, plywood, and sheet goods
- Pipe, tube, conduit, and bar stock
- Steel service center inventory
- Furniture, doors, and windows
- Long or awkward loads currently sitting on the floor
