- High Space Utilization: Maximizes vertical space to double storage capacity without expanding your floor area.
- Forklift Compatible: Compatible with all side loaders and stackers, featuring adjustable arms for flexibility.
- Durable Construction: Premium powder-coated or galvanized finishes resist corrosion in tough environments.
- Quick Installation: Modular bolted connections ensure fast assembly to minimize facility downtime.
Why Choose Spieth’s Cantilever Racking?
In the competitive world of warehouse logistics, the structural integrity of your racking system is non-negotiable.
- Load Capacity: Our systems are built using high-grade steel. Whether you need roll-formed or structural I-beam cantilever racks, our arms are designed to handle heavy loads without deflection.
- Versatile Configurations: Available in single-sided (wall-mounted) and double-sided configurations to maximize your aisle space.
- Pivot Arm Technology: Our arms are designed to pivot upwards upon impact, protecting both the uprights and your material handling equipment (like forklifts) from damage.
- Premium Raw Materials: We use only high-grade Q235B and Q355B cold-rolled steel, ensuring superior tensile strength and durability compared to standard market options.
- Safety Factor Assurance: All our cantilever arms and columns undergo rigorous load testing. We engineer our systems with a high safety factor to handle seismic activity and accidental forklift impacts.
- Advanced Surface Treatment:
- Indoor: Automatic electrostatic powder coating (80-100 microns) ensures a smooth, scratch-resistant finish.
- Outdoor: Hot-dipped galvanized cantilever racks (meeting ASTM A123 standards) provide 50+ years of corrosion resistance in harsh environments.
Cantilever Components: Uprights, Arms , and Base Specs
- Uprights (Columns): Punching holes are spaced at a 75mm or 100mm pitch, allowing for flexible height adjustments as your inventory changes. Available in heights up to 10 meters.
- The Arms (Straight & Inclined):
- Standard Arms: For flat storage of timber and heavy pipes.
- Inclined Arms: Feature a slight upward pitch (typically 2-3 degrees) to prevent round items like PVC pipes from rolling off.
- Safety Pin: All arms are connected via a pivot pin system. If a forklift hits the arm from below, it swings up freely, preventing damage to the upright column.
- The Base: We offer both welded bases (for maximum rigidity) and bolted bases (for easier transport and assembly).

Buyer’s Guide: How to Configure Your Cantilever Rack
Choosing the right configuration is critical for safety and efficiency. Follow this 3-step guide to determine your specifications before requesting a quote:
- Analyze Your Load:
- What is the length, depth, and weight of your product?
- Pro Tip: The load should not extend beyond the length of the arm.
- Determine Arm Count & Spacing:
- To prevent load deflection (sagging), you need the correct number of arms. For example, a 6-meter pack of lumber typically requires at least 3-4 support arms.
- Lateral Spacing: Ensure the distance between uprights allows your forklift to maneuver easily.
- Calculate Capacity:
- Divide the total weight of the load by the number of arms supporting it to find the required capacity per arm.
- Need help? Contact Spieth’s engineering team for a free custom drawing and load calculation.
Installation & Packaging: We Handle the Heavy Lifting
- Easy Assembly:Cantilever systems utilize a bolt-together construction. No on-site welding is required. We provide detailed installation manuals and video guides, making assembly quick for your warehouse team.
- Secure Export Packaging: We understand the risks of global shipping. All components are:
- Wrapped in protective plastic film.
- Secured on steel pallets for easy forklift unloading.
- Reinforced with cardboard corners to prevent paint scratches during transit.
Cantilever vs. Pallet Racking
| Feature | Cantilever Racking System | Standard Pallet Racking |
|---|---|---|
| Best For | Long, bulky, irregular items (Pipes, Timber, Sofa) | Palletized, uniform goods |
| Front Access | 100% Open Access (No front columns) | Restricted by front columns |
| Loading Method | Forklift / Crane / Manual | Forklift mostly |
| Length Flexibility | Unlimited continuous storage length | Limited by beam width |
| Cost Efficiency | Higher ROI for long goods storage | Standard for pallets |
Frequently Asked Questions
A: The capacity depends entirely on the design. A standard light-duty arm might hold 250 kg, while our heavy-duty structural arms can support over 5,000 kg per arm.
Roll-Formed Racks: Made from cold-rolled steel shaped into a "C" profile. They are cost-effective, lighter, and easier to install. Ideal for medium loads like furniture or light timber.
Structural Racks: Made from hot-rolled I-beam steel. They are incredibly robust, withstand forklift impacts better, and support significantly heavier loads. Ideal for industrial steel storage and outdoor use.
A: To prevent your load (like lumber or pipes) from bending (deflection), you must support it adequately.
- Place your product on the ground.
- Use wooden blocks to simulate arm support.
- Test spacing until the product does not sag.
A: Yes, but standard paint will rust. For outdoor applications, you must use Hot-Dipped Galvanized Cantilever Racking. Spieth utilizes an advanced galvanization process that bonds zinc to the steel, providing decades of protection against rain, snow, and salt.
A: This depends on your forklift type.
- Standard Counterbalance Forklift: Typically requires 3.5m – 5m aisles.
- Reach Truck / Side Loader: Can operate in much narrower aisles (2m – 3m), significantly increasing your storage density.
