EXPORT SHIPPING | GLASS HARP RACK
A 12188 project shows the practical freight logic: a 60-slot IGU glass harp rack is designed for knock-down shipment in a 141 × 114 × 20 cm crate, measured at 0.32 cbm and 88.2 kg. The result is not a universal freight quote—it is a measurable packing basis for comparing container space and landed cost.
For an export buyer, the expensive part of a glass rack is often not only steel, wheels, or assembly. It is the empty space around a finished welded frame. A tall rack can occupy a large three-dimensional envelope even when its actual components are relatively slim. That unused air is still charged through container planning, LCL volume, handling, and inland transfer.
The 12188 Hrack project addresses that problem with a bolt-together, knock-down structure. Its specified unit is a small IGU rack measuring 1310 × 600 × 1220 mm when assembled, with 60 slots, a 14.3 mm slot specification available for customization, and 5-inch casters. For shipment, the frame, roller assemblies, dividers, casters, and fasteners are arranged as flat components instead of shipping as one tall rack.
Why does a finished glass rack create high freight exposure?
A finished rack has height, depth, wheels, projecting frame members, and an internal void that cannot normally be filled with other cargo. A simple outer-envelope check for the 12188 assembled dimensions is 1.31 × 0.60 × 1.22 = 0.95868 m³. This is not an invoiceable freight quote, because the open frame, packing clearances, and loading method affect the real result. It is a useful warning: a ready-assembled rack presents roughly three times the geometric envelope of the measured KD crate. The buyer is paying to move a structure plus the air inside and around it.
How does KD assembly compress the shipping footprint?
The design separates the rack into parts that can lie close together: the base frame, side structural members, nylon roller assemblies, PVC-sleeved steel-wire dividers, casters, and bolt hardware. The measured 12188 packing result is 141 × 114 × 20 cm. The arithmetic is 1.41 × 1.14 × 0.20 = 0.32148 m³, reported as 0.32 cbm. A 20 cm package height is the key change: the rack is no longer transported in its operating orientation. It is transported as a flat component set and assembled after arrival.
What does the 12188 package mean for an IGU buyer?
The 0.32 cbm figure gives a purchasing team a concrete input for a forwarder or container-loading worksheet. At 88.2 kg per set, the decision must still check chargeable weight, crate stacking rules, destination handling, and the carrier’s minimums. If the crate format can be loaded efficiently, more sets may fit into the available container volume than fully assembled racks; the exact count depends on the container, other cargo, and loading plan. After delivery, the bolt-together frame is assembled on site, while the 60-slot layout supports sorting or staging of IGU glass rather than long-term bulk warehouse storage.
Shipping checklist for a flat-pack glass harp rack
- Use the project-specific packing basis: for 12188, confirm 141 × 114 × 20 cm, 0.32 cbm, and 88.2 kg per set before requesting freight calculations. Do not replace these figures with a generic rack estimate.
- Confirm the operating configuration separately: this project is 1310 × 600 × 1220 mm, 60 slots, 14.3 mm slot specification subject to customization, and 5-inch casters. Slot width, capacity, and wheel size are project variables.
- Plan receiving and assembly: KD reduces shipping volume but requires a suitable floor, bolt assembly, and inspection of the roller, divider, caster, and lock components before use.
- Check application fit: Hrack is a mobile glass sorting and WIP buffer rack for IGU or glass-processing flow. It is not the right choice when the buyer needs a permanently welded, ready-to-use rack for bulk long-term storage.
