Handling Jumbo Float Glass or heavy IGU shipments shouldn't be a gamble. If your current A-frames are flexing under load or your rubber dunnage is peeling off in the heat, you are risking catastrophic breakage and rejected deliveries. Upgrade to a solution engineered for the 3-ton reality of modern glass fabrication. |
In the glass business, "heavy-duty" isn't a marketing buzzword; it is a necessity. A standard pack of 1/2" (12mm) tempered glass can easily exceed 4,000 lbs. When you transport this kind of weight on a standard hollow-tube rack, dynamic forces from the truck (braking, turning) cause the steel to flex.
The Risk: This flexing creates a "whip" effect. The glass sheets vibrate against each other or the supports, leading to surface scratches on Low-E coatings or, worse, stress cracks that result in spontaneous breakage upon unloading.
The Solution: Our Heavy Duty Glass Rack is built from Q235 Carbon Structural Steel. We utilize Full Seam Welding (not spot welding) on the 50x50mm main load-bearing columns. This rigid geometry ensures the rack remains static even under a 3-ton (6,600 lbs) load, protecting your inventory from transit shock.

Every glass fabricator has seen it: a rack comes back from a job site, and the rubber protection strips are missing. Cheap racks use adhesive to attach rubber pads. In the summer heat of a delivery truck or a glazing site, that glue fails.
The Consequence: Without rubber, you get Metal-on-Glass contact. The raw steel edge of the rack will chip the glass edge (shell chips), creating weak points that cause the glass to explode during tempering or installation.
Our Standard: We use a proprietary Steel-Core Rubber Profile. The rubber is vulcanized around a steel insert and mechanically fastened to the rack frame using self-tapping screws. It cannot peel off, it cannot slide, and it prevents the sharp edge of heavy glass sheets from slicing through the protection layer.

If you are shipping glass to distributors or large commercial projects, getting your racks back is a major cost center. Standard A-frames take up the same amount of truck space empty as they do full. You are essentially paying to ship air.
Our L-Shape Glass Holding Rack features a nesting design. The base geometry allows empty racks to stack horizontally (like shopping carts) or vertically in a compact bundle.
The Math: In a standard truck return, you can fit nearly 7 times as many empty nested L-racks compared to static A-frames. This drastically reduces your return freight costs per unit and clears up valuable floor space in your dispatch area.
Empty racks nested together to maximize storage density and reduce return shipping costs.
Modern fabrication isn't just about raw sheets. You are handling Insulated Glass Units (IGU), laminated safety glass, and finished window frames.
The 90-degree vertical support with a calculated 3-5° tilt ensures that even varying thicknesses of glass stack securely without "walking" or sliding forward. Whether you are moving cut sizes to the tempering furnace or loading finished window units for jobsite delivery, the rack adapts to the workflow, not the other way around.
Storing framed window units securely, demonstrating versatility beyond just raw glass sheets.
1. Can these racks handle Jumbo size sheets (130" x 204")?
Yes, we offer customized dimensions specifically for Jumbo and Split-Jumbo sheets. The structure is reinforced with heavier gauge steel (3.0mm+) to prevent bowing under the immense weight of large-format glass.
2. How are the racks protected against rust during outdoor storage?
For indoor use, we use an electrostatic powder coating (RAL 5010 Blue). For racks that will sit on job sites or outdoor yards, we highly recommend Hot-Dip Galvanizing, which provides 10-20 years of corrosion resistance.
3. Are the racks compatible with overhead cranes?
Absolutely. Each rack is equipped with 4 welded lifting eyelets (lifting pins) on the top corners, designed for safe 4-point lifting via spreader bars or overhead cranes.
4. What prevents the rack from tipping over when loaded with heavy glass?
Since L-racks are single-sided, center of gravity is critical. We engineer the base depth relative to the height and include steel counter-weights (balance blocks) on the back to ensure stability even during forklift braking.
5. Do you ship these racks fully assembled?
To save you ocean freight, we typically ship them in a "knock-down" or nested format. However, the main structural components are welded; minimal assembly (like attaching the rubber or secondary braces) may be required depending on the specific model.
