Heavy Duty Cantilever Rack for Steel, Timber & Pipe Storage — Heavy Cantilever Racking System

The Heavy Duty Cantilever Rack is our industrial-grade cantilever storage system built for the heaviest long-material applications: steel bars, coils, plates, timber, pipes, and structural profiles. Constructed from hot-rolled steel sections and engineered with finite element analysis (FEA), it delivers per-arm capacities of 100–800+ kg and rack heights up to 5 meters, fully compatible with forklift and overhead crane operations.

This cantilever racking system is the proven choice for steel service centers, pipe mills, lumber yards, construction material suppliers, and heavy manufacturing plants where floor stacking is unsafe, inefficient, or impossible. Every system is delivered with a structural calculation report and optional on-site installation supervision, backed by our load-testing laboratory.

Key Features

Per-arm capacity 100–800+ kg — configurable by arm length, column section, and frame spacing

Up to 5m height — multi-level storage doubles or triples usable capacity in tall warehouses

Forklift & crane friendly — open front face allows unobstructed access; optional crane-friendly arm profiles

Bolted or welded connections — choose standard bolt-together (relocatable) or fully welded (maximum rigidity) designs

Anti-corrosion options — hot-dip galvanized or epoxy-polyester powder coating for humid and outdoor environments

Anti-collapse safety — safety pins on every arm connection prevent accidental disengagement during loading

Materials & Workmanship

Columns: hot-rolled H-sections with welded base plates and optional tie beams

Arms: reinforced welded box or I-section arms with end stops and safety pins

Welding: CO2 gas-shielded welding, full-penetration critical joints, 100% visual inspection + optional ultrasonic testing

Surface treatment: sandblasting (Sa 2.5) → zinc-rich primer → epoxy topcoat

Quality control: material certificates (mill test certificates) provided with every batch

Customization & OEM

Fully engineered to your load case — provide item weight, length, and quantity, we design the optimum frame spacing and arm rating

Crane-compatible designs — special arm profiles and clearances for overhead crane handling

Fire protection compatibility — optional fire-retardant paints and sprinkler-compatible layouts

Accessories: side rails, back stops, dividers, safety signage, column protectors

Packaging & Shipping

Packaging: disassembled flat-pack on steel pallets or sea-worthy wooden cases; protective corner guards on all painted parts

Shipping: containerized FCL/LCL, break-bulk and project cargo for extra-long columns (up to 12 m) by flat rack or open top

Lead time: 20–35 days after engineering approval (project-dependent)

Documents: structural calculation report, load test certificate, installation manual, material certificates

FAQ

Q1: What information do you need for a quotation?

 Item length, weight per piece, storage quantity, warehouse height, and whether forklift or crane access is used. With these five inputs we deliver a layout drawing and quotation within 24–48 hours.

Q2: Can existing racks be extended?

Yes. The modular frame design allows adding bays, levels, and arms to existing installations using identical section profiles.

Q3: Do you support overseas installation?

Yes. We provide installation drawings, video guidance, and optional dispatched engineers or local installation partners for large projects.

Q4: What is the maximum single arm length?

Up to 1,500 mm as standard; longer arms (2,000 mm+) are available with reinforced sections on project engineering.
