Stop the "Pop" of Shattered Tempered Glass. |
If you manage a glass fabrication plant or a wholesale distribution center, you know the sound. It’s not the crash of annealed glass; it’s the loud "pop" followed by the cascade of safety glass granules. 90% of the time, this isn't caused by face impact—it's edge stress.
Standard storage racks often use generic rubber strips attached with industrial adhesive. While they look fine on day one, the harsh environment of a float glass warehouse—heat, humidity, and the sheer shearing force of loading 3,000 lbs of glass—causes the glue to fail. Worse, the sharp "knife-edge" of raw glass cuts through soft rubber, eventually making contact with the steel frame. That metal-on-glass contact is a ticking time bomb for your inventory.

To eliminate this risk, we engineered a protection system specifically for heavy duty glass racks. We utilize a specialized EPDM (Ethylene Propylene Diene Monomer) rubber profile that features a vulcanized steel insert running through its core.
Why does this matter for your fabrication line?

Protection isn't just about padding; it's about physics. A perfectly vertical rack risks sheets tipping forward; a rack with too much lean puts excessive dead load on the back sheet, risking crushing. Our L-Shape Glass Rack features a calculated 3-5° incline (roughly an 85-87° angle).
This "micro-tilt" uses gravity to keep the sheets naturally pinned against the backboard without excessive pressure. Combined with the bottom EPDM padding, this ensures that Insulated Glass Units (IGUs) and laminated sheets remain static during forklift movements or truck braking.

For glass distributors, the cost of returning empty racks from the jobsite is a major P&L drain. Traditional A-frames take up the same amount of floor space whether they are full or empty. This is where the L-Rack design revolutionizes your logistics.
Designed with a specific asymmetric base geometry, our racks are fully nestable. When empty, you can slide one rack into another—similar to shopping carts—compressing the volume by up to 70%. This means you can fit nearly 100 empty racks in a standard 40HQ container or a return truck, drastically slashing your freight costs per unit.
Empty racks nesting perfectly to maximize warehouse space and reduce return shipping costs.
Whether you are handling standard 96" stock sheets or custom jumbo architectural glass, structural rigidity is non-negotiable. Our racks are fabricated from Q235 carbon steel with full-seam welding (no spot welds). This ensures that even when loaded with 4,000 lbs of dense laminated glass, the frame does not flex.
Frame flexibility is a silent killer in glass transport; if the rack twists over a bump, the glass twists with it—and shatters. Our rigid, fully welded glass sheet storage racks isolate your cargo from road torsion.

1. Why is screwed-on rubber better than glued rubber for glass racks?
Glued rubber eventually delaminates due to moisture, heat, and shear force. Screwed-on EPDM with a steel core provides a mechanical lock that withstands thousands of loading cycles without shifting, preventing metal-on-glass contact.
2. Can I store mixed sizes of IGUs and raw glass on the same L-Rack?
Yes. The continuous bottom ledge and back support allow for mixed loads. However, we always recommend placing the largest sheets at the back and smaller units at the front to maintain the center of gravity and prevent breakage.
3. How many empty L-racks fit in a shipping container?
Thanks to the nesting design, you can fit approximately 98 units of our standard size (1600x950x1600mm) into a 40HQ container, compared to only about 20-30 traditional non-nestable A-frames.
4. Do these racks support crane lifting as well as forklifts?
Absolutely. Our racks come standard with reinforced forklift channels at the base and four welded lifting lugs at the top, making them compatible with both overhead cranes in the factory and tower cranes at the construction site.
5. What prevents the glass from sliding off during truck transport?
The rack features a 3-5° backward tilt to use gravity for stability. For transport, we provide integrated anchor points for ratchet straps (or steel banding) to firmly secure the glass pack against the rubber-lined backboard.
