Heavy structural cantilever rack in an industrial yard
Engineered Industrial Solutions

Specialized Storage Systems

Heavy-duty structural cantilever racks, multi-tier pick modules, and custom material handling solutions engineered for awkward, long, or ultra-dense warehouse inventory.

Application Engineering

Built For Loads That Defy Standard Pallets

When warehouse inventory exceeds standard pallet footprints or creates severe point-load stresses, conventional selective pallet racks are neither safe nor space-efficient. Pipes, raw steel bars, structural extrusions, timber packs, heavy tooling dies, and complex e-commerce order picking require purpose-built structural steel architecture.

Ridg-U-Rak Storage Systems Inc. manufactures specialized storage rack systems using 100% prime North American steel. Engineered and fabricated under strict RMI R-Mark and CSA W47.1 Division 3 welding standards, our specialized configurations eliminate front column obstructions, deliver massive load capacities up to 10,000+ lbs per level, and optimize high-bay cubic velocity.

Structural cantilever racking system for long lumber and steel pipes
Heavy-Duty · Unobstructed Access

Structural Cantilever Rack Systems

Specifically engineered for products that are long, cumbersome, and irregular. Without front vertical uprights to restrict horizontal placement, cantilever systems provide continuous linear storage for steel tubing, bar stock, dimensional lumber, PVC pipe bundles, and furniture.

Fabricated using heavy hot-rolled structural steel channels or high-strength roll-formed profiles. Arms are fully adjustable vertically on 3-inch or 4-inch increments with heavy-gauge locking pins and optional removable end-stops, pipe saddles, or wire mesh decks.

Column Heights Up to 30+ feet single or double-sided
Arm Capacities 1,000 to over 6,000 lbs per arm
Steel Specification ASTM A36 & ASTM A572 Grade 50
Applications Lumber yards, steel service centers, fabrication
Multi-level pick module rack platform with integrated carton flow and catwalks
High-Density Fulfillment

Multi-Level Pick Module Systems

Pick modules combine heavy pallet rack infrastructure with multi-tier mezzanines, catwalks, carton flow, pallet flow, and package conveyor systems. By utilizing full warehouse vertical cube volume, pick modules create efficient split-case order picking hubs in large-scale e-commerce and retail distribution facilities.

Designed and welded to withstand heavy repetitive dynamic loads, foot traffic, and seismic uplift forces. Handrails, kickplates, stairs, resin-board flooring, and bar grating are seamlessly detailed to meet OSHA and IBC egress codes.

Floor Tiers 2 to 4 vertical working levels
Floor Decking Bar grating, resin-deck, diamond plate
Integration Belt conveyors, spiral chutes, pick-to-light
Compliance IBC, OSHA, NFPA, ANSI MH16.1
Heavy duty die and mold industrial storage system
Severe Point-Load Support

High-Capacity Tool, Die & Mold Racks

Stamping dies, plastic injection molds, and metal casting patterns impose extreme concentrated loads on small surface footprints. Ridg-U-Rak manufactures ultra-heavy-duty structural frames reinforced with solid plate steel decks and heavy structural cross supports.

For rapid maintenance and crane access, roll-out shelf options extend up to 100% of shelf depth, enabling overhead crane hoists or heavy lift trucks to retrieve dies quickly and without rack impact risks.

Capacity per Level Up to 10,000+ lbs uniformly distributed
Shelf Surface Heavy solid steel plate, structural channel
Safety Locks Positive mechanical safety stops on roll-out shelves
Welding Certification AWS D1.1 & CSA W47.1 Div. 3

Buyer Questions

Frequently Asked Engineering Inquiries

What defines specialized storage rack systems compared to standard pallet racks?

Specialized storage systems are custom engineered for inventory profiles that cannot be safely or efficiently handled on standard selective pallet racks. This includes continuous long items such as bar stock, structural pipes, and timber, heavy concentrated dies and molds requiring roll-out shelves, and complex multi-tier order picking modules integrated with automated conveyors.

How does Ridg-U-Rak calculate load capacities for structural cantilever racks?

Ridg-U-Rak Storage Systems Inc. calculates cantilever capacities strictly adhering to ANSI MH16.1 and RMI standards. Our engineering team evaluates arm length, vertical arm clearance, center-of-gravity placement, impact loading factors, steel grade yield strength (up to 50,000 PSI structural steel), and localized seismic accelerations to ensure zero progressive deflection.

Can specialized pick module systems be designed to comply with local seismic building codes?

Yes. Every multi-level pick module is engineered with location-specific IBC/ASCE 7 (for the United States) and NBC (for Canada) seismic parameters. Ridg-U-Rak supplies certified structural calculations and stamped engineering drawings for municipal permit reviews.

Are custom accessories available for tool, die, and roll storage?

Yes. Ridg-U-Rak fabricates custom accessories including 3,000+ lb capacity roll-out shelving, heavy structural plate decks, cradle saddles for cylindrical reels and coiled stock, arm end stops, and guide-rail entry funnels for narrow-aisle material handling equipment.
