Key Players
Competitive Landscape
Competition separates carton-flow design from other equipment around the pick face. In August 2026, Mallard published guidance that separates full-case and split-case work from each-pick setups. Interroll's March 2026 catalog includes Carton Flow in its live-storage range for order picking. These updates make package shape and pick method key parts of system choice. Logistics 4.0 programs can add automation around the lane. The gravity surface still must move the actual container reliably.
Carton flow often works as one part of a mixed picking process. In January 2026, Mecalux published split-case picking guidance that shows live storage with pick-to-light at AS Healthcare. The example connects gravity presentation with visual picking support instead of treating the rack as a standalone asset. Suppliers sell flow parts and engineered racks for mixed picking work. Some suppliers also link the rack to assisted picking systems. Procurement teams still need use proof before approval. The proposed setup must support the load and surrounding workflow without adding avoidable start-up risk.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| Mallard published August 2026 guidance for full-case, split-case and each-pick carton flow. | Different picking units require different lane presentation. | Application guidance is becoming more load-specific. | Match track layout to the actual pick method before release. |
| Interroll published a March 2026 catalog that includes Carton Flow within dynamic storage. | Order preparation needs compact gravity-fed presentation. | Dynamic storage remains part of integrated material-flow portfolios. | Combine carton flow with adjacent handling systems without changing the load test. |
| Mecalux published January 2026 split-case guidance documenting live storage with pick-to-light. | Split-case work raises the value of short travel and clear pick cues. | Gravity storage is being paired with visual picking assistance. | Integrate live storage with guided picking for dense manual workflows. |
In 2026 Mallard, Interroll and Mecalux documented carton-flow use and links to live storage or assisted picking.

Together these companies cover carton-flow hardware plus live storage and assisted picking.
Which providers document the deepest configurable carton-flow product evidence?
UNEX and Interroll show several carton-flow formats. Mallard and Frazier also provide direct carton-flow systems that users can adjust. The right provider depends on the load and rack interface. No single product suits every use.
Which providers document retrofit paths for existing rack structures?
UNEX, Interroll and Frazier show ways to update existing rack. PRODEX also describes how its system fits existing rack structures. Teams still must check the host rack and actual load before approval.
Which providers combine carton flow with engineered pick-module structures?
Frazier and Steel King show rack platforms that support flow-based picking. Ridg-U-Rak and Nucor Warehouse Systems also support flow-based pick modules. SSI Schaefer and Mecalux place gravity storage inside wider picking systems.
Which providers connect gravity lanes with picking-assistance technology?
SSI Schaefer and Mecalux connect live storage with assisted picking. Interroll supports pick-to-light placement on carton flow. Integrators can combine these tools when the workflow needs the added control layer.

Research Methodology
The competitive map uses official company updates and current product records about carton-flow hardware or picking links. Product pages show current capability. Dated company posts show only the action and timing they describe. Benchmark placement uses the shown carton-flow range and rack design. It also checks how each company links its products with picking systems. The map states geographic reach only when public company material supports it. The map is illustrative rather than a full ranking. It does not assign company market shares.
