 | In the global glass and fenestration market, the most expensive component isn’t always the product—it’s the freight. Shipping “air” across the ocean in partially filled containers destroys margins. Furthermore, traditional wooden crates face strict customs scrutiny regarding ISPM-15 heat treatment regulations. Switching to a steel Collapsible Glass Storage Transport Rack solves both problems. It is a certified “non-wood packing material” that speeds up customs clearance, while its calculated dimensions allow you to maximize the floor space and weight capacity of every shipping container.

Bypassing ISPM-15 Quarantine Issues
Wooden crates used for export must be heat-treated and stamped to prevent the spread of pests. However, stamps fade, paperwork gets lost, and wood can grow mold during weeks at sea, leading to containers being quarantined or rejected at the port of entry.
Steel racks are immune to these biological risks. They require no fumigation certificates and face zero quarantine delays. For an export manager, this reliability means your glass arrives at the customer’s warehouse on schedule, without the risk of unexpected demurrage charges due to customs hold-ups.
Calculated for Container Fit
Export logistics is a game of Tetris. Standard A-frames are often too wide or too tall to fit efficiently in a container, leaving “dead space.”
As shown in the technical drawing below, the Collapsible Glass Storage Transport Rack is engineered with precise dimensions (e.g., typically designed to fit two rows wide in a standard 90″+ wide container). This allows exporters to double the volume of glass per container compared to using mismatched wooden crates. Every inch of the container width is utilized, effectively halving the shipping cost per square foot of glass.
Precision engineering: Racks are dimensioned to maximize lane width in 20GP and 40HQ shipping containers.
Secure Loading on Ramps
Loading a heavy container on a chassis ramp is dangerous. The angle of the ramp can cause poorly secured glass to shift. The forklift channels (shown in the header image) on these racks are fully enclosed and reinforced. This allows the forklift operator to tilt the rack back safely while driving up the ramp, ensuring the glass pack remains settled against the back supports throughout the loading process.
The Circular Economy: Returnable Packaging
For companies with regular trade lanes (e.g., a factory in Mexico shipping to a distribution center in Texas), these racks enable a circular economy. Instead of buying wood for every shipment, you use the racks for the outbound journey. Once unloaded, the racks are folded down (10 racks take the space of 1) and returned in a single batch. The ROI on the steel assets is often realized within 5 to 6 round trips compared to disposable packaging.
Frequently Asked Questions
Yes. They are specifically designed to fit within the internal dimensions of standard 20GP and 40HQ containers, usually allowing for side-by-side loading to maximize width utilization.
Yes, if the glass height permits. For shorter glass packs, you can stack loaded racks two-high inside a High Cube (HQ) container to fully utilize the vertical space.
No. The racks arrive fully assembled. The receiver simply needs to unload them. If they are returning them empty, they can fold them down in seconds without any tools.
Salt air is corrosive. We recommend Hot-Dip Galvanizing for any racks used in ocean freight. This provides a metallurgical bond that protects the steel far better than paint, even if the surface is scratched.
Since the racks are made of steel and rubber, they do not require a phytosanitary certificate. We can provide a “Non-Wood Packing Declaration” to speed up the customs clearance process.
