Stack Racks

RACKsteel’s stack racks, also referred to as portable racks or modular stacking systems, are designed steel structures for temporary, mobile, or flexible storage of palletized or specific materials. Stack racks allow vertical stacking to increase storage density and can be nested when empty to minimize floor space requirements. These systems provide controlled load support without permanent anchoring, making them suitable for applications like manufacturing and maintenance, where conventional static racking is impractical.

Stack racks are ideal for seasonal overflow storage, staging areas, inter-facility transport, and environments requiring mobile, temporary, or reconfigurable storage. Structural configurations are available to accommodate heavy-duty industrial applications, including automotive, steel processing, distribution, and agricultural operations.

Stack Rack Configurations

RACKsteel supplies both standard and custom stack rack configurations to meet operational and site-specific requirements. Standard systems are available for immediate use, while custom solutions are engineered to support specific load capacities, material types, or operational constraints.

Customizable features include:

Modified post heights for specific stacking or clearance requirements
Reinforced bases for higher load capacities
Mesh or solid deck options for palletized or loose materials
Material-specific cradles for irregular or long items
Structural-grade construction for heavy industrial use

Stack racks are designed to optimize storage density while allowing for mobility, temporary placement, and easy reconfiguration as operational needs change.

Stack Rack Engineering

RACKsteel provides full engineering support for stack rack projects when requested as a separate fee. Our capabilities include:

Structural and seismic compliance review, including heavy-duty and industrial applications
Engineering and load calculation

Custom-fabricated stack racks can be engineered to meet unique load specifications, environmental requirements, and facility constraints. All designs are intended to maximize safety, stability, and long-term operational performance.

Applications

Stack racks are used in facilities where temporary or flexible storage is required. Common applications include:

Seasonal or peak-period inventory storage
Staging areas for inbound or outbound materials
Mobile or reconfigurable storage between facilities
Storage of specific, oversized, or palletized materials
Heavy-duty industrial storage
Specialized community transit operations for bogie units and trains

These systems are particularly suitable for operations where traditional static racking is not practical due to space limitations, frequent layout changes, or short-term storage needs.
