Stop paying to transport air. For glass fabricators, the return trip of empty racks is the hidden profit killer in your supply chain. Our Foldable A-Frame Glass Rack system compresses this void, turning a logistical nightmare into a streamlined operation that protects your high-value Low-E and laminated units while slashing freight bills. |
Every Logistics Director in the glass industry knows the pain of reviewing freight invoices for return trips. You send out a flatbed fully loaded with custom IGUs or jumbo laminated sheets to a construction site. The delivery is profitable. But then, you pay nearly the same rate to haul back a truckload of empty, fixed steel racks. In the industry, we call this "shipping air," and it directly erodes the margins of your architectural glass projects.
Traditional fixed flat glass racks are rigid structures. They occupy the same footprint empty as they do full. This inefficiency forces you to dispatch five trucks to retrieve the empty racks that one truck delivered.
The GSR-Zmgrack Solution: We engineered a Collapsible Glass Stillage specifically to break this cycle. By utilizing a heavy-duty hinge and pin system, our racks achieve a 5:1 stacking density. This means you can fit up to 60 folded racks into a single 40HQ container or standard flatbed return. Mathematically, this cuts your reverse logistics costs by 80% immediately.
Saving on freight is meaningless if the glass arrives broken. A common failure point in cheap alternatives is the rubber padding. In standard racks, rubber strips are often glued to the steel. After a few months of exposure to summer heat in a container or coolant fluids near the glass edging machine, that glue fails. The rubber peels off, leaving your expensive soft-coat Low-E glass to rub directly against bare metal.
Our Engineering Logic: We don't use glue. The Zmgrack features a Heavy-duty glass transport rack design where flat rubber strips are reinforced with an internal steel core and mechanically fastened using self-threading pins directly into the Q235 carbon steel frame. This ensures that even under the 3,300 lbs (1500kg) static load capacity, the cushion never shifts, protecting the glass edge from shelling and the surface from micro-scratches.
In a busy glass fabrication plant, workflow flow is critical. The Zmgrack is not just a storage unit; it is a mobility tool designed to interface with your existing machinery.
Whether you are moving glass from the offloading table of a Glass tempering furnace or loading a delivery truck, the rack's base is equipped with standardized fork guides. These guides are customizable to your specific forklift center distance, ensuring that the forks always engage the center of gravity. This eliminates the risk of tipping during rapid braking or cornering in the yard.
Furthermore, the open-end design solves the "Jumbo Size" problem. Unlike enclosed crates, our Demountable A-Frame Rack allows for glass sheets longer than the rack itself (up to 6 meters/20 feet) to overhang naturally without obstruction, making it perfect for curtain wall units and oversized storefront glazing.
Wooden A-frames warp, rot, and require expensive disposal. Fixed steel racks drain your budget on return freight. The Zmgrack represents a permanent asset for your logistics fleet. With hot-dip galvanization options to prevent rust during sea freight and a robust tubular steel structure, these racks are built to cycle between your factory and your customers for over 15 years.
When the job is done, simply pull the pins, fold the uprights, and stack them. Your warehouse floor space is reclaimed, and your return transport costs are minimized.
1. Can this rack handle the weight of 19mm thick jumbo glass sheets?
Yes. The Zmgrack is rated for a static load capacity of 3,300 lbs (1500kg). It is constructed from high-strength Q235 carbon steel to ensure structural integrity even under heavy loads.
2. Will the rubber pads damage Soft-Coat Low-E glass?
No. We use specially formulated rubber that is non-marking and moderately soft to cushion the glass. Crucially, the pads are mechanically fixed with steel cores, so they never slip or peel, preventing metal-to-glass contact.
3. How many empty racks can I fit on a standard truck for return?
Due to the nesting design, you can stack the folded racks efficiently. A standard 40HQ container or a full-size flatbed can accommodate approximately 60 folded units.
4. Does the rack support glass longer than the base length?
Yes. The design features open sides with no vertical obstructions at the ends. This allows you to safely transport glass sheets or window frames that are significantly longer than the 2200mm base, such as 3.7m or 6m curtain wall units.
5. Is the rack compatible with vacuum lifters and overhead cranes?
Absolutely. The A-frame angle (typically 3-5 degrees) is optimized for easy loading and unloading using vacuum lifters. The open top structure ensures no interference with crane cables or suction cup positioning.
