125-Ton American Pallet Racking DDP Project in Waterloo, Canada: 4,603 Pallet Positions Across Four Rack Zones

Project Background

A leading flooring and building-materials distributor in Waterloo, Ontario, Canada needed a complete pallet racking system for its new distribution warehouse at 100 Northland Road. The 198'-6" x 169'-6" (60,502 mm x 51,663 mm) building had to be converted into a high-density, high-throughput storage operation without sacrificing picking speed or forklift safety. Our team was awarded the entire scope: layout optimisation, manufacturing, DDP delivery to the customer's warehouse, and full on-site installation.

Project Snapshot

The Challenge

• Four rack profiles in one warehouse. The layout required Rack A, Rack S, Rack B and Rack C, each with its own depth, bay length and frame height, all coordinated under a single drawing set.
• 125 tons delivered DDP. Freight, Canadian customs clearance, duties, inland trucking to Waterloo and staged unloading all sat with one supplier before a single upright was stood up.
• Mixed frame heights. Standard uprights at 414" (34'-6") had to be combined with 429" (35'-9") frames wherever a cross aisle was created, while keeping beam elevations perfectly level across runs.
• Tight tolerances for narrow-aisle handling. The high-bay zones are served by narrow-aisle turret trucks, so plumb, straightness and beam-level accuracy directly determine whether the equipment can operate safely.
• Compressed installation window. Racking, inspection and handover had to finish on a fixed date ahead of stock transfer.

The Solution: Four-Zone American Pallet Racking

American-style roll-formed pallet racking was selected for its fast boltless assembly, adjustable beam pitch and the lowest cost per pallet position at high bay heights. The approved layout delivers 241 bays and 4,603 usable pallet positions with zero lost positions.

Rack A and Rack B — High-Bay Double Runs

Both zones use 96-1/4" (8') bays at 42" depth, with upright frames at 414" and 429" where cross aisles cut through the runs. Each bay stores 18 pallets on 40"-wide loads of up to 2,600 lbs, with nine beam levels set on a 42" pitch. Rack A contributes 1,764 positions in 98 bays; Rack B, the largest zone, contributes 2,304 positions in 128 bays.

Rack S — Cross-Aisle Transition Run

Rack S mirrors the 96-1/4" x 42" x 414" profile but is kept as a short 4-bay transition run at the cross aisle, holding 10 pallets per bay for 40 positions. It preserves the aisle geometry the customer's trucks need to turn between the A and B runs.

Rack C — 12' Wide Bays for Long Loads

Rack C steps up to 144-1/4" (12') bays and 48" depth on 345" (28'-9") frames, holding 26"-deep long loads rated at 1,200 lbs per position. Forty-five positions per bay across 11 bays give 495 positions. Drop-in panels at each level and dedicated cross aisles keep long-length handling fast and stable.

DDP Delivery and Installation

The complete 125-ton package shipped as a single DDP contract covering export packing, ocean freight, Canadian import clearance and duties, inland delivery to the Waterloo warehouse, and crane-assisted unloading. Our installation crew then executed frame erection, beam levelling, wire decking, cross-aisle and drop-in panel fitting, plumb and straightness verification, and a joint walk-through with the customer before handover. The USD 80,000 installation package removed every coordination risk from the distributor's team: they received an inspected, ready-to-load warehouse instead of a container of steel.

Results

• 4,603 usable pallet positions delivered with 0 lost positions
• 125 tons of racking across 241 bays in four independent zones
• 414" and 429" mixed-height frames levelled within tolerance for safe turret-truck operation
• One DDP contract: freight, duty, delivery and installation handled by a single supplier
• Handover completed on the agreed date

Key Takeaways for Similar Warehouse Projects

1. Define zone-by-zone bay geometry early. Mixing 8' and 12' bays in the same building is efficient only when the aisle and cross-aisle plan is fixed first.
2. Plan high-bay frames around the truck, not the other way around. At 34'-6", beam level tolerance is a safety issue.
