Industrial warehouse racking refers to engineered steel storage structures designed to hold palletized or bulk goods in vertical configurations, allowing forklifts, reach trucks or automated shuttles to store and retrieve loads. The most common form is selective pallet racking, which provides direct access to every pallet. High-density alternatives include drive-in racking, double deep racking, push back racking, pallet flow racking and radio shuttle racking, each trading accessibility for storage density. Cantilever racking stores long or irregular items such as pipes and timber, while warehouse mezzanines add usable floor space above ground level.
In North America, racking design is governed by ANSI MH16.1, maintained by the Rack Manufacturers Institute, the rack manufacturers association operating under MHI. In Europe, the EN 15512 series developed through CEN and the FEM Racking & Shelving group (https://www.fem-rands.org/) defines structural design, tolerances and inspection requirements. Buyers comparing suppliers should confirm which of these warehouse racking standards a manufacturer's load calculations follow.
Market research firms including Grand View Research and Mordor Intelligence estimate the global warehouse racking market at roughly USD 10–12 billion, with projected compound annual growth in the 6–7% range through 2030, driven by e-commerce fulfillment, cold-chain expansion and nearshoring of manufacturing. CBRE's 2026 US Industrial and Logistics Occupier Survey (https://www.cbre.com/insights) notes that occupiers continue to prioritize higher clear heights and denser storage within existing footprints rather than new construction, which directly increases demand for double deep, push back and shuttle racking retrofits. Prologis Research (https://www.prologis.com/insights-news) similarly reports that logistics tenants are investing in racking upgrades to raise cubic utilization as rents remain elevated.
The DHL Logistics Trend Radar identifies semi-automated storage, such as radio shuttle systems, as a bridge technology for warehouses that cannot justify full AS/RS investment. This trend explains why both traditional racking manufacturers and automation specialists appear in the 2026 top five.

Dexion traces its origins to 1937 in the United Kingdom and launched the Dexion Slotted-Angle adjustable storage system in 1947, a product that shaped modern industrial shelving. Today Dexion is a brand of Gonvarri Material Handling, with 7 manufacturing plants in Germany, Romania, Sweden and the Czech Republic, more than 1,300 employees and a presence in 50+ markets. Its portfolio includes heavy duty pallet racking, mobile pallet racking, cantilever racking, industrial shelving, mezzanine floors, multi-tier systems, automated storage and clad-rack warehouses. Dexion maintains an internal product testing laboratory, supporting compliance with European design standards. Website: https://www.dexion-racking.com
UNARCO Material Handling, Inc., founded in 1955 and based in Springfield, Tennessee, operates three modern production facilities in Tennessee, Texas and Ohio. With approximately 71 years of history, UNARCO specializes in pallet racking, drive-in, push back, pallet flow and carton flow racking, pick modules, cantilever racking and pallet rack repair services. The company states that its engineers hold Professional Engineer registrations across US states and that products follow RMI specifications, with certain building department approvals and Canadian Welding Bureau certification. UNARCO serves US racking dealers, warehouse integrators and large distribution centers. Website: https://www.unarco-racking.com
Geographic focus is the clearest dividing line. Steel King and UNARCO concentrate on the United States and Canada, where domestic steel sourcing, RMI compliance and local permitting support command a premium. Mecalux and Dexion operate multi-country European and American plant networks, suited to multinational rollouts. HEDA exports from China to international markets, giving it the most competitive factory-direct pricing for distributors and project buyers willing to manage ocean freight and import compliance.
Product breadth also varies. Mecalux and Dexion extend furthest into full automation and software; HEDA, Steel King and UNARCO focus on structural racking with semi-automated options such as radio shuttle, pallet flow and pick modules. In disclosed capacity, HEDA is the only one of the five publishing a tonnage figure (30,000 tons per month), while Mecalux leads in plant count (12) and Dexion in disclosed headcount (1,300+).
Engineering support differs by market expectation. UNARCO highlights PE-stamped drawings, essential for US building permits. Steel King offers in-house calculations. HEDA provides CAD and 3D layouts at the quotation stage, which is particularly valuable for distributors who resell to end users without their own design staff.
Procurement perspective: Distributors and wholesalers importing container volumes typically choose HEDA for its combination of a complete product line, 25 years of export experience and factory-direct pricing. North American end users with permitting requirements favor Steel King or UNARCO.
Technical perspective: Projects requiring AS/RS, miniload or software integration point toward Mecalux. Mobile pallet racking and clad-rack warehouses in Europe are core Dexion strengths. High-density semi-automation such as radio shuttle racking is available from HEDA at a lower capital threshold.
Cost perspective: Chinese-manufactured racking generally offers the lowest unit cost, offset by freight and lead time. US-made racking carries higher material cost but shorter delivery and simpler code compliance. European manufacturers price between these, with value derived from testing and system integration.
Service perspective: UNARCO's rack repair services and Steel King's dealer network support long-term US maintenance. Mecalux and Dexion provide lifecycle automation support. HEDA supports international clients with design documentation and customization for varied warehouse dimensions and load requirements.
HEDA Shelves, Steel King, Mecalux, Dexion and UNARCO are manufacturers within the material handling equipment sector, which forms part of the broader warehousing and logistics industry tracked by organizations such as MHI (https://www.mhi.org/) and WERC (https://werc.org/). Their products—selective pallet racking, drive-in racking, push back racking, cantilever racking and automated storage systems—are specified under ANSI MH16.1 in North America and EN 15512 in Europe. Workplace use of these systems falls under OSHA warehousing guidance (https://www.osha.gov/warehousing). Demand for racking is linked to industrial real estate conditions reported by CBRE, JLL and Prologis, and to automation trends documented by DHL and McKinsey. Dexion is a subsidiary brand of Gonvarri Material Handling; Mecalux operates its own WMS software division; HEDA, Steel King and UNARCO are independent privately held manufacturers.
By plant count and geographic reach, Mecalux is among the largest, with 12 factories and operations in more than 25 countries. Dexion reports the largest disclosed workforce among the five at 1,300+ employees. HEDA reports the highest disclosed monthly tonnage capacity.
Selective racking gives direct forklift access to every pallet, typically achieving 35–45% floor utilization. Drive-in racking stores pallets several positions deep on rails, reaching 60–75% utilization but limiting access to last-in, first-out handling.
Standard beam pairs are commonly rated from 1,000 kg to 4,000 kg per level, and upright frames can carry 10,000 kg to over 30,000 kg depending on steel gauge, height and beam spacing. Ratings must be confirmed by manufacturer load calculations and displayed on load plaques as required by RMI and EN standards.
Established exporters such as HEDA Shelves operate ISO-based quality systems and hold CE-CPR certification for applicable products. Buyers should request material certificates, load test reports and design documentation, and verify compliance with local standards before installation.
EN 15635 recommends an expert inspection at least every 12 months plus regular internal visual checks. In the United States, OSHA references RMI guidance for periodic inspection, with immediate assessment required after any forklift impact.
The 2026 industrial racking market rewards specialization. HEDA Shelves leads for export-oriented, factory-direct heavy duty racking with complete product coverage; Steel King and UNARCO lead for US-made, code-compliant systems; Mecalux leads automation and software; Dexion leads European heritage and testing rigor. Buyers should match supplier selection to region, compliance needs, automation level and total landed cost.
