Double-Sided Cantilever Rack System — Two-Sided Long Material Storage with Forklift Access
Product Overview
Built on the same proven cold-rolled and hot-rolled steel platforms as our single-sided series, the double-sided frame carries arms on both column faces with independent height adjustment on each side. It is the preferred solution for sheet metal, plate, lumber, pipes, and long profile storage where high density and fast access must coexist.
As a professional cantilever racking manufacturer, we deliver complete double-sided systems — frames, arms, base assemblies, aisle guidance, and accessories — with free layout design and load verification.
Key Features
- Two-sided storage, one footprint — arms on both column faces approximately double capacity per floor area vs. single-sided layouts
- Clean center aisle — straight, unobstructed aisle between faces optimizes forklift travel and pick efficiency
- Independent arm adjustment per side — each face is configured separately, so mixed product lengths and load classes share one line
- Wide capacity range — per-arm ratings from 500 kg (light) to 2,000+ kg (heavy) on the same frame family
- Flexible bay widths — 1,000–3,000 mm to match sheet, plate, and pipe lengths
- Multiple access levels — 2–6 levels per side for tall-space utilization
- Safety by design — end stops, safety pins, and optional back stops on every arm
- Modular expansion — add frames, extend aisles, or add levels without structural re-engineering

Materials & Workmanship
- Frames: symmetrical column sections welded to a common base, tie-beamed for lateral stability
- Arms: reinforced stepped or box profiles on both faces, bolted for independent adjustment
- Base: welded base plates with anchor holes; optional floor rail guides
- Surface: phosphating + powder coating (60–80 µm), or hot-dip galvanizing for outdoor/humid sites
- QC: material certificates, dimensional inspection per drawing, and assembly trials before packing
Applications
- Sheet metal & plate storage — steel, aluminum, and stainless sheets on both faces
- Timber & panel centers — plywood, MDF, particle board, and lumber lengths
- Pipe & tube distributors — split inventory across faces by size or grade
- Aluminum extrusion plants — aging racks and finished-goods storage
- Automotive & appliance plants — long body parts, rails, and trim profiles
- Steel service centers — rebar and long sections with high turnover
Customization & OEM
- Aisle and crane layouts — we design frame spacing, aisle width, and optional crane clearance to your handling equipment
- Mixed load classes — one line can combine light and heavy arms on opposite faces
- Accessories: side rails, end stops, back stops, dividers, safety signage, column guards
- Engineering support: free layout and load calculation within 24–48 hours from your dimensions and SKU list
Packaging & Shipping
- Packaging: flat-pack frames and arms on steel pallets with protective wrapping; extra-long columns by flat rack or open-top container
- Shipping: FCL/LCL and project cargo available worldwide
- Lead time: 15–30 days after drawing approval
- Documents: structural calculation, installation manual, load test report, packing list, and commercial invoice
FAQ
Q1: How much floor space does a double-sided rack save?
Compared with two separate single-sided racks, the shared column line typically saves 15–25% of floor area while delivering the same storage capacity, and it creates a cleaner forklift aisle.
Q2: Can each side hold different products?
Yes. Each face has independent arm positions and load ratings, so you can store lumber on one side and pipes on the other in the same bay.
Q3: What is the recommended aisle width?
For standard counterbalance forklifts, 3,000–3,600 mm; for reach trucks, 2,400–2,800 mm. We factor your equipment into the layout drawing.
Q4: Can the system be extended later?
Yes. Add frames at either end, add levels, or add arms to existing columns — all components are re-orderable and matchable.
Q5: Do you install overseas?
We provide full installation drawings and video guidance free of charge; dispatched engineers or local partners are available for large projects.
