Choose a storage unit before relying on the 3,000 kg rating
A bundled-long-material storage plan works when the bundle, carrier and restraint method are treated as one storage unit. A total weight alone does not show whether a bundle is stable on the supports or whether its center of load remains acceptable during transfer. Send the packed cross-section, bundle length, heaviest unit and carrier tare with the quotation request.
The 6 m figure describes the typical material length. It does not include a carrier allowance, end clearance, receiving space or the travel envelope for the gantry. A layout drawing must establish those dimensions after the bundle and handoff position are known.

Load ratings and layout suitability depend on the approved carrier, support and operating arrangement.

Keep bundle restraint and downstream handoff separate from gantry storage
The gantry stores and retrieves an agreed carrier or storage unit. It does not establish a universal bundle restraint method or turn a stored bundle into a single-bar supply system. If a saw, drill line or machining cell needs individual pieces, define who removes material at the transfer point and how unused material returns to storage.
Receiving should use the same unit definition as storage. If incoming bundles vary in width, wrapping, dunnage or length, identify those differences before a rack and carrier layout is released. This prevents a nominal 3,000 kg total from concealing a support or restraint issue.
Fixed and mobile racks answer different access questions
Fixed cantilever racks with a gantry keep permanent aisles between rack groups. They suit operations that need several stable access lanes. Mobile cantilever racks with a gantry move complete rack rows on rail-guided bases to open one shared operating aisle. They suit layouts where permanent aisle area is the larger constraint.
Neither arrangement uses roll-out or telescopic cantilever arms. In a mobile layout, the bases and full rack rows move; the arms remain ordinary fixed cantilever arms.

Plan the handoff zone and the operating envelope together
Start the layout from the receiving and transfer point, then map the carrier path through the rack area. The engineering review needs the lowest overhead obstruction, column grid, floor information, rail route, receiving position and downstream handoff. The known product information confirms a gantry height of up to 10 m and rack heights of 7 to 8 m, but it does not supply an installation dimension for this bundle application.
A good fit is a plant that stores repeated bundle formats and can define the carrier and restraint method before ordering. It is not the right choice when bundles change without a controlled storage-unit definition, or when the next process requires automatic single-piece feeding that has not been specified.
FAQ
Request a bundle-storage layout
Send the maximum material length, heaviest full bundle, bundle cross-section, carrier tare, restraint method, receiving position and a plan of the available floor area. CK METAL STORAGE SOLUTIONS will use these inputs to prepare a layout discussion and define the storage-unit basis for quotation.
See our contact page to request a layout discussion. For broader system background, read CK METAL STORAGE SOLUTIONS automated profile storage information.
