Unlocking Warehouse Efficiency: A Guide to 7 Essential Racking Systems

Is your warehouse bursting at the seams? Are your teams spending more time navigating cluttered aisles than fulfilling orders? The secret to reclaiming your space and boosting productivity isn't always a bigger building—it's smarter storage. The right industrial racking system can transform your operations, optimizing every square foot and streamlining your inventory flow.

As experts in warehouse and retail storage at TriState Material Handling, we’ve seen firsthand how the perfect racking solution can make all the difference. But with so many options, how do you choose the right one? In this guide, we’ll walk you through seven essential types of warehouse racking to help you find the perfect fit for your needs.

The All-Rounder: Selective Pallet Racking

If you’re looking for the most common and versatile racking system, you’ve found it. Selective pallet racking is the go-to choice for countless warehouses, and for good reason. It provides direct, "selective" access to every single pallet, making it ideal for operations with a wide variety of product types (SKUs) and low turnover for each.

Unmatched Flexibility

The beauty of selective pallet racking lies in its adaptability. The beams are easily adjustable, allowing you to reconfigure your storage for products of different sizes and weights without a major overhaul. Whether you're storing small parts or oversized pallets, this system can handle it.

Simple and Scalable

This system is straightforward to install and relatively cost-effective. Its simple design means you can easily expand your storage as your business grows. The team at TriState Material Handling can help you design a selective racking layout that maximizes your current space and plans for future growth.

Maximize Your Floor Space: Very Narrow Aisle (VNA) Racking

When floor space is at a premium, it’s time to think vertically and condense horizontally. Very Narrow Aisle (VNA) racking does just that. By significantly reducing the width of the aisles—sometimes to as little as 6 feet—VNA systems can increase your storage capacity by up to 50% compared to selective racking. This design requires specialized equipment, like turret trucks or order pickers, to navigate the tight spaces, but the density gains are often worth the investment.

Wondering if a VNA system could work for you? Our experts at TriState can assess your facility and operational flow to see if it’s the right high-density solution.

Boost Your Storage Density: Double Deep Racking

Double deep racking offers a great middle-ground between selective and high-density systems. As the name suggests, it involves storing pallets two deep in a single rack. This immediately doubles your storage capacity for a given lane and reduces the number of aisles needed, freeing up valuable floor space.

This system operates on a Last-In, First-Out (LIFO) basis, so it’s best suited for storing multiple pallets of the same SKU. You’ll need a specialized reach truck with extended forks to access the rear pallet, but it’s an incredibly efficient way to increase density without the infrastructure of a full drive-in system.

High-Density Heroes: Drive-In & Pallet Flow Racks

When you need to store large quantities of uniform products, compact storage systems are your best bet. These solutions prioritize density over selectivity.

Drive-In/Drive-Thru Racking

This is the ultimate space-saver. A forklift can physically drive into the racking structure to deposit or retrieve pallets.

• Drive-In Racking uses a single entry/exit, making it a LIFO system perfect for products that aren't date-sensitive.

• Drive-Thru Racking has entry and exit points on both sides, enabling a First-In, First-Out (FIFO) flow for perishable or date-sensitive goods.

Pallet Flow Racking

For an automated FIFO solution, look no further than Pallet Flow. These racks are built on a slight incline with rollers that allow pallets to glide forward automatically. New pallets are loaded from the back, and as a pallet is picked from the front, the next one slides into place. It’s a fantastic system for managing inventory with expiration dates and ensuring constant product rotation.

Beyond the Pallet: Versatile Longspan Shelving

Not everything you store comes neatly on a pallet. For hand-loaded, bulky, or long items, Longspan shelving is the ideal solution. Think of it as the heavy-duty big brother to standard shelving. It’s strong, durable, and features wide, unobstructed spans, making it perfect for storing everything from cartons and archive boxes to pipes and timber. Its simple, boltless design makes it easy to assemble and adjust.

Go Vertical: Multi-Tier Racking Systems

Why build out when you can build up? Multi-tier racking systems are an ingenious way to capitalize on the vertical height of your warehouse. This system essentially uses racks to create one or more additional floor levels within your existing structure, complete with walkways and stairs for foot traffic. It’s an excellent way to double or even triple your usable floor space without the expense of moving or construction, making it perfect for picking and sorting operations.

Supercharge Your Order Picking: Carton Flow Racks

In the fast-paced world of e-commerce and piece-picking, speed and accuracy are everything. Carton flow racks use the same gravity-fed principle as pallet flow, but for individual cartons and totes. Products are loaded from the rear and slide down inclined shelves to the picking face. This ensures that items are always front-and-center for your pickers, dramatically increasing efficiency, reducing errors, and ensuring FIFO rotation for your fastest-moving products.
