Shipping Warehouse Racking: Container Loading From Factory to Site
Direct answer: A 40HQ container holds roughly 22–26 tonnes of racking by weight but is usually limited by volume, while a 20GP holds about half that. Because uprights and beams are long, nested and bundled, the practical limit is almost always cubic metres rather than payload.
Container planning belongs in the quotation
Ocean freight is priced by container rather than by kilogram, so the practical question in any export order is how much of the container you can fill. That is decided by component lengths and the packing pattern, which is why our loading plan is produced from the same drawing package as the CAD layout instead of after production. The aim is a container-optimised stack for 20GP or 40HQ that maximises fill rate and cuts freight cost per pallet position.
The mix matters just as much. Mixed container loading is supported, so one shipment can combine racking, steel pallets and cages, which is usually what makes a first order economic. Quotations are returned within 24 hours and include FOB pricing, so landed cost can be compared between a 20GP and a 40HQ before anything is booked. The same drawing package then produces the container loading plan, the detailed packing list and the loading photographs that are issued with every shipment.
How the components are packed
Uprights and beams leave the roll-forming and robotic welding lines, pass surface treatment, and are then assembled and re-checked against the approved drawing before packing. Every finished unit is dimensionally inspected, so the packing list matches what is actually loaded rather than what was ordered. Uprights, beams and their fixings are bundled separately, because bundled lengths stack into a container far more efficiently than assembled frames.
Protection is specified at the same time. Standard packing uses plywood edge protection and steel strapping, the fill rate of a 40HQ is calculated rather than estimated, and every container ships with a detailed packing list and loading photographs. Plywood edge protection is offered on request for container-optimised stacking, and the steel strapping is applied so bundled lengths cannot shift during a long sea voyage. Those photographs are also what a receiving team uses later if a damage claim has to be settled.
Lead times and how orders are structured
Standard production runs 18 to 30 days per container, and 30 to 45 days for container-sized automated projects after drawing approval. Minimum quantities are deliberately low so a project can be validated before volume: standard racking starts from five bays and a single bay can be supplied for a pilot, while standard steel pallets start from ten pieces with custom prototyping from a single piece.
Spare parts are held for the same reason. Common beams, uprights and anchors are kept in stock and re-dispatched within three to seven days, so a damaged bay does not wait for a production slot. That is worth confirming before ordering, because the cheapest quotation is of little use if a replacement upright later has to be made to order from scratch and shipped on its own.
Documents that arrive with the shipment
Mill test certificates are archived per batch and copies ship with every container, so the steel grade can be traced from the finished rack back to the mill, and incoming steel is spectrometrically re-verified before it enters production. Each batch also carries coating thickness and adhesion results, a dimensional inspection record taken against the approved drawing, and load test rig validation on sample pieces.
Where we install or supervise, handover includes a laser leveling report together with on-site photo and video records. Four delivery models are available, from self-install with a full drawing and video pack, through remote supervision and one or two engineers on site, to a turnkey installation crew, and every mode carries the same records. Racking carries a 12-month structural warranty with lifetime maintenance support, and drawings, load reports, installation plans and certificate scans are supplied on request at any point afterwards.
FAQ
Is a 20GP or a 40HQ the better choice for racking?
It depends on the component lengths and the packing pattern rather than on weight, because ocean freight is charged per container. We produce a container loading plan from the same drawing package as the CAD layout and calculate the 40HQ fill rate, so you can compare landed cost per pallet position between a 20GP and a 40HQ before booking.
Can I mix racking, pallets and cages in one container?
Yes. Mixed container loading is supported, and it is usually what makes a first order economic. Send the quantities of each line you need and the loading plan will show how they combine, with a detailed packing list and loading photographs issued for every container.
How long does production and shipping take?
Standard production runs 18 to 30 days per container, and 30 to 45 days for container-sized automated projects after drawing approval. Quotations are returned within 24 hours and the free CAD layout with loading plan follows within 48 hours of receiving the floor plan, clear height, pallet specifications and throughput.
What if I need a replacement upright after installation?
Common beams, uprights and anchors are held in stock and re-dispatched within three to seven days. Send photographs and the bay configuration and we will identify the correct section from the original drawing so the bay can be returned to service quickly.
