Pallet Racking for Indianapolis Area Manufacturers

Manufacturing facilities have fundamentally different racking requirements than distribution centers — and treating them the same way is one of the most common mistakes in warehouse design. While a distribution center stores finished goods in uniform pallet quantities, a manufacturing facility stores raw materials in bulk, manages work-in-process (WIP) inventory at every stage of production, and often handles long, oddly shaped materials that standard pallet rack can't accommodate at all. This guide is specifically for manufacturers in the Indianapolis metro area, Anderson, Greenfield, Shelbyville, and the broader Central Indiana manufacturing corridor.

Indiana's Manufacturing Sector: The Context

Indiana is consistently one of the top five manufacturing states in the US by output — and Central Indiana punches above its weight even within Indiana. The Indianapolis metro area and surrounding counties support a diverse manufacturing base that includes:

• Automotive and auto parts: Subaru's manufacturing campus in Lafayette, multiple Tier 1 and Tier 2 suppliers throughout Indianapolis, Anderson, and Muncie. Automotive manufacturing creates racking demand for heavy stampings, subassemblies, and just-in-time component sequencing storage.
• Pharmaceutical and life sciences: Eli Lilly's global headquarters and manufacturing operations in Indianapolis, along with a cluster of contract manufacturers and medical device producers across Marion and Hamilton counties. This sector requires FDA-compliant storage solutions with precise inventory tracking capabilities.
• Agricultural equipment and food processing: Extends from the Indianapolis metro into the surrounding counties — Shelby, Hancock, Madison — where agricultural supply chain manufacturers require storage for large, heavy seasonal inventory.
• Defense and aerospace: Several defense contractors operate facilities in the Indianapolis area, with storage requirements for precision components, long-shelf-life materials, and controlled access inventory zones.
• Electronics and consumer goods: Assembly and light manufacturing operations distributed throughout the suburban industrial parks in Avon, Brownsburg, Greenfield, and Noblesville.

Each of these sectors has distinct racking requirements — and getting the storage infrastructure right directly impacts production efficiency and material handling costs.

Production Workflow Racking: WIP and Raw Material Zones

The most important distinction in manufacturing racking design is the separation of material flow zones. A well-designed manufacturing storage system distinguishes between:

Raw Material Storage

Bulk raw materials typically arrive in large quantities and need high-density storage that supports FIFO (first-in, first-out) or LIFO rotation depending on the material. Drive-in rack and pushback rack are common choices for homogeneous raw materials where the entire lane holds the same SKU. For raw materials that must be FIFO-rotated — as in food processing or pharmaceutical manufacturing — pallet flow rack is often the better solution, loading from the back and allowing pallets to gravity-flow forward as they're consumed.

Work-In-Process Storage

WIP inventory is the most dynamic and often the most poorly stored category in manufacturing facilities. WIP needs to be accessible at multiple production stages, often stored in smaller quantities with frequent retrieval, and clearly organized by production order or stage. Selective pallet rack works well for WIP because every position is directly accessible — critical when you need to pull a specific production batch without disturbing surrounding inventory. However, WIP storage often involves non-standard container sizes, totes, and partial loads that require adjustable beam configurations.

Finished Goods Staging

Manufacturing facilities need finished goods staging areas adjacent to the shipping dock. This zone benefits from narrower aisles and higher density because the product mix is more uniform and throughput is more predictable than in WIP areas. Many Indianapolis area manufacturers use a hybrid layout with wide-aisle selective rack for WIP and narrow-aisle rack for finished goods staging.

Cantilever Rack: Essential for Long Materials

Standard pallet rack is designed for palletized unit loads. For long, awkward materials — bar stock, pipe, tubing, lumber, extrusions, sheet metal coils, rolled goods — cantilever rack is the correct solution. Cantilever rack uses horizontal arms extending from a vertical column, with no front upright to obstruct loading from the side. This allows long materials to be stored horizontally at multiple height levels with full-length access along the entire arm.

In Central Indiana manufacturing, cantilever rack is heavily used by:

• Steel service centers and fabricators throughout the Indianapolis metro area
• Millwork and building products manufacturers in the Anderson/Muncie corridor
• Automotive stamping operations storing steel coil and flat sheet stock
• Plastics processors storing extruded profiles and sheet material
• Agricultural equipment manufacturers storing long frame components and structural members

Cantilever rack comes in two primary configurations: single-sided (arms on one side only, stored against a wall) and double-sided (arms on both sides, accessed from either side). Arm length, arm capacity, and column height all need to be engineered for the specific materials being stored.

The Anderson and Shelbyville Manufacturing Corridor

The manufacturing communities east and southeast of Indianapolis — particularly Anderson (Madison County) and Shelbyville (Shelby County) — have a concentration of automotive and industrial manufacturers with significant racking needs that differ from the larger Indianapolis metro market:

• Anderson: A historically significant automotive manufacturing city that has diversified its industrial base. Anderson facilities often have older building stock with lower clear heights and heavier floor loads from legacy manufacturing operations — factors that require careful engineering analysis before racking installation.
• Shelbyville: Home to several automotive Tier 1 and Tier 2 suppliers, Shelbyville manufacturers frequently need high-throughput sequencing storage for just-in-time delivery to assembly plants. This typically means a combination of flow rack, carton flow, and well-organized selective rack with tight location management.
• Greenfield (Hancock County): A growing industrial community with newer building stock and several pharmaceutical and healthcare-related manufacturers. Greenfield facilities often need FDA-compliant storage solutions with smooth surfaces, minimal ledges, and easy-clean configurations.

Indiana Building Code Considerations for Manufacturing Facilities

Manufacturing facilities face some specific code considerations that don't typically apply to distribution centers:

• Higher floor load ratings: Manufacturing floors are often designed for heavier equipment loads than distribution warehouses. This is generally an advantage for racking — the concrete slab is typically more robust — but it means anchor bolt specifications need to match the actual floor, not default distribution center assumptions.
• Fire suppression and commodity class: Manufacturers often store raw materials that are classified as higher-hazard commodities under NFPA 13, which can trigger different in-rack sprinkler requirements or flue space requirements between rack rows. This needs to be coordinated with the fire protection engineer before finalizing rack layout.
• Seismic design: Indiana's seismic design requirements apply to manufacturing facilities just as they do to warehouses. The Indianapolis metro area falls within Seismic Design Category B for many facility types — requiring seismic calculations as part of the permit package.
• Process equipment clearances: Manufacturing facility racking must be designed around process equipment, overhead cranes, conveyor systems, and utility drops in ways that pure storage facilities don't require. This makes manufacturing racking layout more complex and typically requires more coordination time before final engineering.

Working with Indy Pallet Racking on Manufacturing Projects

Manufacturing racking projects require more pre-installation planning than standard distribution center work. We bring experience with the specific challenges of Central Indiana manufacturing facilities — including older building stock in Anderson and Muncie, the tight just-in-time requirements of automotive suppliers throughout the corridor, and the FDA compliance needs of Indianapolis's pharmaceutical and healthcare manufacturing sector.
