Handling 130" x 204" jumbo sheets is not just about heavy lifting; it's about preventing the catastrophic "shelling" of edges that turns a $5,000 sheet of architectural glass into a bin of cullet. Stop relying on improvised wood crates or light-duty A-frames that flex under torque. You need a dedicated logistics system designed for the float glass line, not a general warehouse shelf. |
In the world of glass fabrication, verticality is a myth. Truly vertical storage is a safety hazard. However, excessive lean creates "dead weight" pressure on the bottom sheets, leading to friction scratches on soft-coat Low-E layers. Our L-Shape Glass Holding Rack utilizes a calculated 3-5° micro-tilt.
This specific geometry directs the vector force into the Q235 steel spine of the rack, rather than relying solely on the glass's own surface tension. Whether you are storing raw float glass or completed IGUs, this angle ensures the pack stays consolidated during forklift braking without the risk of the front sheet "slapping" forward.
The most common failure point in generic glass racks is the bottom protection. When you load 4,000 lbs of glass sheets, the bottom edges act like a knife blade. Standard glued-on rubber strips will shear off or compress until the glass contacts the steel—resulting in immediate edge chipping or spontaneous breakage during tempering.
We utilize a Steel-Core Rubber Profile. This isn't just a rubber pad; it has a steel insert vulcanized inside it. We secure this to the base using self-tapping screws, creating a mechanical bond that glue can never achieve. This ensures that even under the load of heavy architectural panels, your glass never touches the metal frame.
If you are shipping glass on A-frames, you are paying to ship "air" on the return trip. A standard A-frame takes up the same floor space empty as it does full. For high-volume glazing contractors and distributors, this eats into margins.
Our returnable shipping racks feature a nesting L-design. When empty, they slide into one another—much like shopping carts. You can fit approximately 7 empty racks in the space of 2 full ones. This capability alone can reduce your return freight costs by over 60%, turning your logistics department from a cost center into a competitive advantage.
Jumbo sheets often need to move from the cutting table to the tempering furnace, and then to the loading dock. Maneuverability is key. Unlike static frames, our racks are equipped with reinforced forklift channels (180x80mm) that allow safe entry from all sides.
For sites utilizing overhead cranes, we integrate four fully welded lifting lugs at the top corners. This allows for stable crane picking without the rack twisting—a common cause of stress cracks in large IGU units during internal transfer.

Q: Can these racks handle 19mm thick heavy-duty architectural glass?
Yes. Our racks are constructed from Q235 structural steel with a wall thickness of up to 3.0mm in critical stress areas. They are rated for working loads between 3,300 lbs and 8,800 lbs (1.5 to 4 tons), making them ideal for heavy laminated or thick float glass. |
|
Q: How do you prevent rust contamination on the glass?
We offer two finishes: Electrostatic Powder Coating (standard RAL 5010 blue) for indoor factory use, or Hot-Dip Galvanizing for racks stored outdoors or shipped overseas. Galvanizing provides a sacrificial zinc layer that prevents rust from staining your glass inventory. |
|
Q: Will the rubber pads damage soft-coat Low-E glass?
No. We use non-marking EPDM rubber with a specific shore hardness (70-80 Shore A). It provides enough grip to prevent sliding but is soft enough to avoid scratching delicate coatings or leaving residue that interferes with washing machines. |
|
Q: Can I stack loaded racks?
No, loaded L-racks should generally not be vertically stacked unless specifically engineered with corner posts. However, our empty racks are designed to nest (stack horizontally/telescopically) or stack vertically (inverted) for storage efficiency. |
|
Q: Do you support custom dimensions for non-standard Jumbo sheets?
Absolutely. While we have standard 96" and 100" lengths, we frequently fabricate custom racks for 130" x 204" Jumbo sheets or specific manufacturing line requirements. |
