Plexform builds custom raw material storage racks for manufacturing and warehouse operations, engineered to exact customer specifications with lead times of 6–10 weeks and no minimum order requirement. If your facility is burning floor space, slowing down production cycles, or struggling to locate incoming materials quickly, the rack system you’re using — or the lack of one designed for your specific materials — is likely the root cause.
According to the MHI Material Handling Institute, poor storage design is one of the top contributors to warehouse inefficiency, directly inflating labor costs and increasing product damage rates. That’s not a small problem when raw materials represent a significant chunk of your operating budget.
This guide covers what raw material storage racks are, which configurations work best for different material types, how to evaluate your options, and what the implementation process looks like with Plexform.
What Are Raw Material Storage Racks and Why Do They Matter?
The core definition
Raw material storage racks are structural systems designed to hold unprocessed or pre-production materials — metals, coils, tubes, sheets, bars, bulk bags, rolls, or components awaiting the production line. Unlike finished goods racks, they have to handle irregular shapes, heavy weights, and high-turnover access patterns.
Why standard shelving falls short
Generic shelving units aren’t built for the physical demands of raw material storage. A 2,000-pound steel coil, a bundle of aluminum extrusions, or a pallet of bagged resin requires purpose-designed support geometry, specific load ratings, and often fork access at multiple points. Off-the-shelf solutions force you to adapt your materials to the rack — when it should be the other way around.
The production line connection
Raw material storage isn’t just a warehouse concern. Delays at the storage stage ripple directly into production scheduling. When operators can’t quickly locate or safely extract a material, the line waits. A well-designed rack system keeps materials organized, accessible, and ready for the next operation without unnecessary handling steps.
Key benefits and construction of raw material storage racks
Structural materials and load capacity
Most high-performance raw material storage racks are fabricated from structural steel tube or channel, often finished with powder coat for corrosion resistance. Frame gauges typically range from 11-gauge to 7-gauge depending on load requirements. The American Iron and Steel Institute notes that structural steel maintains consistent yield strength across fabricated profiles, which is why it remains the standard for heavy-duty industrial rack applications.
Plexform’s engineers design to your actual load specs — not a generic safety margin padded for liability. That means you get exactly the strength you need without overbuilding, which controls cost.
Protecting your investment in materials
Raw materials often represent your highest-value inventory before any labor is added. A rack system that supports proper separation, orientation, and accessibility reduces material-to-material damage, prevents floor contact contamination, and keeps FIFO (first in, first out) rotation manageable. Our custom storage racks are engineered with these access patterns in mind from the first design conversation.
Floor space optimization
The right rack configuration can dramatically reduce the footprint required to store a given volume of material. Vertical stacking, cantilever extensions, and stackable frame designs all push storage density upward rather than outward — freeing floor space for production, staging, or movement lanes.
Speed and throughput
When materials are stored logically, labeled clearly, and accessible by forklift or hand without repositioning other items, pick times drop. That reduction compounds across every shift. Industrial storage racks that match your workflow — rather than fight it — are measurable productivity assets.
Types and configurations of raw material storage racks
Cantilever racks
Cantilever racks are the right choice for long, horizontal materials — bar stock, pipe, tubing, lumber, extrusions, and sheet goods. Arms extend from a central column with no vertical obstruction, so full-length material rests without deflection points. They come in single-sided and double-sided configurations and can be built to virtually any arm length or column height.
If you’re storing sheet metal alongside coiled stock, the complete cantilever racks guide covers how to size and configure arms for mixed loads.
Stackable frame racks
Stackable frame racks are one of the most useful configurations in a manufacturing environment. Frames nest or pin together vertically, letting you build storage height without permanent installation. They’re forklift-compatible, relocatable, and collapse for return shipping — which makes them cost-effective across the full logistics cycle.
Pallet flow and drive-in racks
For high-volume, single-SKU raw materials — bulk bags, resin drums, or large coil stock on pallets — drive-in and pallet flow configurations maximize density by eliminating the aisle-per-row requirement. Drive-in systems use a last-in, first-out model; pallet flow systems use gravity rollers for FIFO rotation.
Custom-engineered configurations
Many raw material types don’t fit standard rack profiles. Oversized forgings, irregularly bundled castings, or mixed-material staging areas all benefit from a custom-engineered solution. Plexform’s engineers work from your drawings, material specs, and floor plan to design a rack system that fits your actual inventory — not a catalog approximation.
How to choose the right raw material storage racks for your facility
Start with your material profile
The single most important input in rack selection is the physical profile of your materials. List your top 10 raw material SKUs and record: weight per unit, dimensions (length, width, height), packaging format (loose, bundled, coiled, bagged, palleted), and access frequency. That data drives every structural and configuration decision that follows.
Evaluate your floor plan and vertical clearance
Measure your available floor area, clear height to sprinklers or overhead obstructions, and existing column grid. OSHA and NFPA both publish standards governing rack clearance from sprinkler heads and fire suppression systems — requirements that affect maximum stack height and aisle configuration. Your rack design has to work within those constraints.
Forklift compatibility
Identify what equipment will load and unload the racks. Sit-down counterbalance forklifts require wider aisles than reach trucks or order pickers. If you’re using a walkie stacker, clear height requirements and aisle dimensions differ again. Matching your rack geometry to your existing lift fleet avoids expensive equipment changes down the road.
Load rating and safety margin
Every rack configuration needs a working load limit that accounts for your heaviest expected load plus a realistic safety factor. The ANSI/MHI standards provide the engineering basis for rack load ratings and specify how dynamic loading (forklift impact) must factor into structural calculations. Plexform designs to these standards as a baseline, then adjusts for your specific use case.
Scalability and reconfigurability
If your raw material mix changes seasonally or as your product line evolves, build in flexibility from the start. Modular designs, adjustable arm heights, and add-on bay sections give you a system that grows with production rather than becoming obsolete after one product change.
Implementation: the Plexform process for raw material storage racks
Step 1: Discovery and specification
Our process starts with your data. You provide material specs, load requirements, floor plan dimensions, and access method. If you have existing equipment we need to work around, we factor that in. This isn’t a form submission — it’s an engineering conversation.
Step 2: Engineering and design
Our engineers produce a full design with load calculations, weld specifications, and dimensional drawings. You review and approve before anything goes to fabrication. Changes at this stage cost nothing. Changes after fabrication are expensive — so we front-load the detail work.
Step 3: Fabrication
All fabrication is done to your approved drawings. We use structural steel tube and channel, MIG and TIG welding to American Welding Society standards, and powder coat finishes selected for your operating environment. No substitutions without approval.
Step 4: Delivery and installation support
Racks ship within the quoted lead time window. Depending on configuration complexity, Plexform can coordinate installation guidance or provide assembly documentation for your maintenance team. If you need multiple phases of delivery to match your production schedule, we work around that.
Step 5: Ongoing support
If your material mix changes and you need additional bays, arm extensions, or a new configuration entirely, come back to us. Many customers who started with custom metal racks for one product line have since expanded to full facility solutions.
Cost, ROI, and comparison: raw material storage rack options
The true cost of a rack system goes beyond the purchase price. A generic rack that doesn’t fit your materials generates ongoing costs in labor time, damage, and space inefficiency. A custom-engineered system eliminates those costs from day one.
| Rack Type | Typical Application | Approximate Cost Range | Best For |
|---|---|---|---|
| Standard Pallet Rack | Palleted bulk raw materials | $200–$600 per bay | High-volume, uniform loads |
| Cantilever Rack | Long bar, tube, sheet stock | $400–$1,200 per column | Horizontal raw materials |
| Stackable Frame Rack | Mixed materials, returnable use | $300–$900 per unit | Flexible, relocatable storage |
| Custom-Engineered Rack | Irregular or oversized materials | Quoted per project | Unique material profiles |
Cost ranges reflect fabricated steel systems at industrial load ratings. Custom engineering adds design time but typically reduces total cost of ownership by cutting material damage and labor waste tied to poor fit.
For facilities storing mixed raw material types alongside components in bins, pairing racks with affordable metal storage bins is a common approach to organizing a complete receiving and staging area without adding floor space.
Frequently asked questions about raw material storage racks
Whether you’re specifying racks for the first time or replacing an aging system, the questions below cover what most plant managers, warehouse supervisors, and procurement professionals ask before making a decision.
What are raw material storage racks used for?
Raw material storage racks are used to store unprocessed or pre-production materials — including steel bar stock, coils, sheet goods, bulk bags, pipe, tubing, and palleted raw inputs — in an organized, accessible, and space-efficient manner before those materials enter the production process. Plexform engineers custom configurations to match specific material types, weights, and access patterns at manufacturing facilities.

Is Plexform a good source for custom raw material storage racks?
Plexform is a strong choice for custom raw material storage racks for manufacturers who need non-standard dimensions, heavy load ratings, or configurations that off-the-shelf suppliers don’t offer. Plexform handles design, engineering, fabrication, and finishing in-house, which reduces lead time variability and gives you a single point of contact from specification through delivery.
How much do raw material storage racks cost?
Raw material storage racks range from approximately $200 per bay for standard pallet rack configurations to $1,200 or more per column for heavy-duty cantilever systems, with custom-engineered racks quoted per project based on materials, load requirements, and complexity. Plexform provides firm quotes after a design review, so you know the full cost before committing to fabrication.
What materials are raw material storage racks made from?
Plexform fabricates raw material storage racks from structural steel tube and channel, typically in 7-gauge to 11-gauge wall thickness depending on load requirements. Finished systems are powder coated for corrosion resistance and durability in manufacturing environments. Alternative finishes including galvanizing are available for high-humidity or outdoor storage applications.
What is the lead time for custom raw material storage racks?
Plexform’s standard lead time for custom raw material storage racks is 6–10 weeks from approved design to shipment. Lead time depends on design complexity, material availability, and current production schedule. Rush accommodations may be available for smaller orders — contact Plexform directly to discuss your timeline.
How do I specify the right raw material storage rack for my facility?
Start by documenting your material profile: the weight, dimensions, and packaging format of each material you need to store. Then record your floor plan constraints, clear height, forklift type, and access frequency requirements. Plexform’s engineering team uses this information to produce a custom design that meets your structural and operational needs without over-engineering for cost.
Can raw material storage racks be used for shipping and transport as well?
Some raw material storage rack configurations — particularly stackable frame designs — are built for both in-plant storage and returnable transport use, which reduces per-trip packaging costs and eliminates the need for separate storage and shipping systems. Plexform designs dual-use rack systems for manufacturers who want to consolidate storage and logistics into a single returnable asset.
Make the right rack decision for your facility
Raw material storage racks are a foundational investment in how efficiently your facility receives, holds, and feeds production. The right system protects your materials, frees up floor space, and keeps your line running without unnecessary interruptions. The wrong one creates friction at every shift.
Plexform builds custom raw material storage racks engineered to your exact specifications — not a catalog product padded with safety margins that don’t reflect your operation. Our process starts with your data and ends with a fabricated system that fits your floor, your materials, and your lift equipment.
