Engineering Experience
Cantilever storage racking structures carry unique engineering challenges. Unlike conventional pallet racks with rear and front beams, a cantilever system relies entirely on a single upright column and a series of single-ended load arms. The absence of outer support profiles creates massive moments of bending force and shear stress at the column-to-base and column-to-arm connections. Therefore, compliance with European standards (CE Mark) is not merely a legal checkbox—it is a critical safety safeguard.
We design our cantilever systems to comply perfectly with standard EN 15635 (Application and Maintenance of Storage Equipment). This standard outlines strict rules on structural deflection tolerances, regular load tests, and the minimization of risk under seismic conditions.
Every customized load plan undergoes rigid FEA testing in our CAD environment. This virtual simulation maps high-stress concentrations on connection collars and welded joints, allowing us to prevent elastic deformation under extreme unbalanced loading configurations.
Our raw material feedstock consists of premium cold-rolled and hot-rolled structural steel coils (such as Q235B and Q345B grades). Tensile tests ensure the minimum yield strength satisfies engineering calculations before production begins.
| Racking Component | Typical Steel Grade | Yield Strength (MPa) | Corrosion Resistance | Safety Factor Rating |
|---|---|---|---|---|
| Structural Columns (H-Beams) | Q345B / ASTM A572 | ≥ 345 MPa | Hot-Dip Galvanized / Powder Coated | 1.5 x Max static load limit |
| Cantilever Arms (Tapered C-Section) | Q235B / ASTM A36 | ≥ 235 MPa | Electrostatic Epoxy Powder Paint | 1.5 x Nominal capacity |
| Base Assemblies | Q345B / Heavy Plate | ≥ 345 MPa | Galvanized & Anchor bolted | 2.0 x Overturning moment |
| Connection Pins & Bolts | Grade 8.8 / 10.9 High Tensile | ≥ 640 MPa | Zinc Plated / Dacromet coating | Special structural grade |
The rise of Industry 4.0 is transforming warehousing from simple static physical steel structures into highly integrated, intelligent material handling assets. Standard static storage shelves are evolving rapidly to adapt to high-throughput automation. Kelida's research division is actively exploring and integrating key trends within the global materials handling roadmap:
We are developing specialized structural tolerances for automated storage and retrieval systems (AS/RS). By manufacturing tighter deflection profiles, our racking interfaces perfectly with high-speed automated crane shuttles and robotic arms, eliminating operational downtime caused by structural sag.
The future of safety inspection involves digital sensors embedded inside structural members. Our R&D team is testing fiber-optic strain gauges that send real-time deflection metrics to warehouse managers, detecting overloading risks before deformation occurs.
Reducing VOC emissions and structural carbon footprint is critical. Our modern powder coating lines run on clean electricity, using lead-free, non-toxic epoxy resins. All steel components are fully recyclable at the end of their multi-decade life cycle.
Standard racking systems often fail when managing long, heavy, or irregular materials. Cantilever racks remove the front obstruction barrier, offering continuous storage space that accommodates complex geometries. Across diverse heavy-industry sectors, our customized layouts resolve critical operational bottlenecks:
Lumber packs are susceptible to sagging and surface damage if not supported correctly. Our cantilever arms are configured with customizable spans and plastic protectors, maintaining lumber flatness while maximizing vertical cube space.
Circular materials tend to roll off standard shelves. We design dedicated arm stoppers (welded or removable pins) that secure metal profiles, pipelines, and structural extrusions, protecting floor crews from load shifts.
For engine blocks, chassis structures, and heavy machinery tooling, our high-capacity structural steel columns are combined with guiding guide rails for heavy-duty forklifts, eliminating impact damage during picking cycles.
Operating a massive 28,000 square meter factory, Ningbo Kelida Shelf Co., Ltd. implements automated manufacturing processes that guarantee structural precision. From precision laser profile cutting to robotic welding and automated powder coating line operations, each stage is monitored by our team of 22 QC specialists.
Our integration with over 650 qualified raw material and hardware component partners creates a highly resilient supply chain. This robust sourcing network protects our clients from price volatility and production bottlenecks, securing reliable lead times even during global shipping disruptions.
For international buyers, the purchase price of steel racking represents only a portion of the Total Cost of Ownership (TCO). Unplanned installation modifications, shipping damaged goods, structural failure, and corrosion failures dramatically escalate long-term operating costs. Kelida addresses these vulnerabilities through strategic engineering and quality assurances:
Our engineering team designs cantilever structures based on your local seismic zone requirements, floor slab ratings, and handling machinery specifications. We provide complete structural calculation profiles for easy local permit approval.
We execute standard salt-spray corrosion tests in our QC laboratory. Our industrial electrostatic powder finishes protect columns and arms in humid environments, reducing maintenance costs.
Our cantilever configurations utilize adjustable arm connectors. If your product line inventory changes, arms can be easily repositioned in 75mm or 100mm increments without structural welding, protecting your initial investment.
