EXPORT PACKING / IGU PRODUCTION
A 12188 project shows how a 60-slot IGU glass harp rack changes the freight calculation: the assembled rack serves the production floor, while its bolt-together structure ships KD in a 141 × 114 × 20 cm crate measuring 0.32 cbm and weighing 88.2 kg.
For a glass equipment trader or purchasing team, the freight problem is often not the rack’s steel weight alone. A welded glass rack can occupy a large three-dimensional footprint even when it is empty. That unused air becomes chargeable container space, raises the number of rack positions needed per shipment, and makes a small order harder to quote competitively. The right question is therefore not only “How many slots does the rack have?” but also “What is the shipping form of the rack before it reaches our plant?”
The 12188 reference gives a concrete answer without pretending that one packing figure fits every Hrack. This small IGU rack is specified at 1,310 × 600 × 1,220 mm when assembled, with 60 slots, a 14.3 mm slot configuration that can be customized, and 5-inch casters. For export, the bolt-assembly design is taken apart and packed flat. Its measured KD package is 141 × 114 × 20 cm, or 1.41 × 1.14 × 0.20 m. Multiplying those three outside dimensions gives 0.32148 cubic metres, which is reported as 0.32 cbm. The same project records a packed weight of 88.2 kg.
Why does freight cost rise when the rack is shipped assembled?
In an assembled state, the rack’s height, sloping frame, base, rollers, dividers, casters, and lock hardware occupy separate layers of empty space. The glass is not inside the shipment, but the carrier still has to reserve the rack’s full outer envelope. For a buyer comparing several units, that can reduce usable container density before the cargo is even loaded. The freight rate itself depends on route, carrier, season, and shipment terms, so this project does not support a universal freight amount. It does support a more useful comparison: a production-ready rack has an assembled envelope, while the same 12188 rack is documented for a compact KD crate.
How does the bolt-together design compress the shipping volume?
KD means the main frame is not treated as one permanently assembled welded envelope for transport. The base, side frame members, roller assemblies, casters, divider grid, and fasteners can be arranged as flat components, then protected and secured in the export crate. The 12188 package is 20 cm high, which is the key volume result: the rack’s working height is converted into a low, layered package rather than shipped as a tall empty structure. On arrival, the buyer assembles the sections with bolts and restores the 60-slot working layout. A close inspection of the bolted base also helps clarify what is being shipped: this is a mechanical assembly intended for installation, not a claim that every Hrack model has identical joints or identical crate dimensions.
That conversion matters for procurement in two ways. First, the buyer can compare the 0.32 cbm package against the planned order quantity before asking a forwarder for a quote. Second, several units can be evaluated as a combined cargo plan instead of assuming that every rack consumes its full assembled footprint. The final number of units per container still has to be confirmed against the container type, internal clearances, crate orientation, other cargo, and loading restrictions.
What exactly is the 12188 KD package?
Use the project data as a purchasing baseline: 60 slots for IGU sheet sorting and staging; assembled size 1,310 × 600 × 1,220 mm; 14.3 mm slot configuration, customizable to the glass mix; 5-inch casters; KD crate size 141 × 114 × 20 cm; calculated volume 0.32148 cbm, reported as 0.32 cbm; packed weight 88.2 kg. The rack’s job is production flow—sorting single sheets, buffering work in process, and staging paired IGU sheets—not bulk warehouse storage. Slot width, base support, caster size, finish, and other dimensions should be confirmed against the buyer’s glass thicknesses, shapes, floor conditions, and handling route. Do not transfer this project’s 0.32 cbm or 88.2 kg to a larger custom rack without a packing confirmation.
What should an exporter confirm before ordering?
- Quantity and shipping basis: send the number of racks, destination, container type, and other cargo so the 0.32 cbm-per-unit project reference can be converted into a real loading plan rather than an assumed freight saving.
- Glass and slot fit: confirm IGU dimensions, glass thickness range, edge condition, and sorting mix. The 12188 project uses 14.3 mm slots, but slot spacing is customizable and is not a universal Hrack value.
- Assembly and receiving: confirm that the destination team can assemble a bolt-together rack and has a level working area for the 5-inch caster configuration and floor-lock operation.
- Scope of the quote: request the exact KD crate dimensions, packed weight, component protection, and shipping marks for the ordered configuration. A larger, full-base, or differently customized rack needs its own packing calculation.
