Screw-fixed rubber protection glass dollies

Is “Ghost Breakage” Eating Your Margins? For glass fabricators and distributors, there is nothing more frustrating than loading perfect Insulated Glass Units (IGUs) onto a truck, only to find chipped edges or shattered lites at the jobsite. The culprit often isn’t the driver—it’s the adhesive on your rack’s rubber strips failing under the California sun, leading to fatal glass-to-steel contact. Secure your high-value inventory with mechanical fixation, not glue. Talk With An Expert

The Engineering Flaw in Standard Glass Racks

In the glass fabrication industry, particularly for those handling Wholesale Tempered Glass or heavy laminated sheets, the integrity of the contact surface is non-negotiable. Traditional A-frames often use general-purpose rubber strips attached with industrial adhesive. While this works in a climate-controlled warehouse, it fails during transport.

Under the weight of 3,000 lbs of glass and the vibration of the road, glued rubber “creeps” or peels off entirely. Once the sharp edge of a Glass sheet storage rack cuts through the soft rubber, or the strip falls off, your glass hits bare steel. The result is immediate shelling or catastrophic stress fractures, often discovered only when the glazier unloads at the construction site.

The Solution: Screw-Fixed, Steel-Core Protection

To eliminate this risk, our Screw-fixed rubber protection glass dollies utilize a specialized EPDM profile with a vulcanized steel core. This is not a simple bumper; it is a structural component of the rack.

• Mechanical Fixation: The profile is anchored to the rack frame using self-tapping screws through the internal steel plate. It cannot peel, slip, or detach, even under extreme heat or shear forces.
• Cut Resistance: The internal steel core acts as a stop. Even if a heavy, raw-edge float glass sheet cuts into the rubber, the blade hits the internal steel plate, distributing the load and preventing the glass from touching the structural tube.
• Soft-Coat Safety: The EPDM compound is formulated to 70-80 Shore A hardness, providing enough cushion to protect sensitive Low-E coatings on Insulated Glass Units without compressing to the point of failure.

From Storage to Shipping: The L-Shape Logistics Advantage

Beyond protection, logistics efficiency drives the bottom line for glass distributors. While A-frames are stable, they are notorious “air shippers” on return trips. Our L-Shape Glass Holding Rack features a nesting design that revolutionizes reverse logistics.

Once the glass is offloaded at the customer’s shop or jobsite, the empty racks can be stacked like shopping carts. You can fit approximately 7 empty racks in the footprint of 2 full ones. This reduces return freight costs by up to 70%, making it feasible to use these racks as a returnable asset system for regional deliveries.

Heavy-Duty Specs for the Glazing Industry

These are not lightweight shop carts. They are engineered for the rigors of heavy industrial handling.

• Structural Integrity: Built with Q235 carbon steel (equivalent to ASTM A36), featuring full seam welding rather than spot welding. This ensures the frame does not twist under the load of jumbo sheets.
• Load Capacity: Rated for 3,000 to 8,800 lbs (1.5 – 4 Tons), making them suitable for packs of heavy laminated glass or thick architectural panels.
• Fabrication Friendly: Designed for 4-way forklift entry and overhead crane lifting, integrating seamlessly into your cutting line workflow or loading dock operations.

Frequently Asked Questions (Glass Industry)

Q: Will the rubber profile stain the edges of PVB laminated glass?

A: No. We use high-grade EPDM rubber that is non-marking and chemically stable, preventing any reaction or discoloration on the PVB interlayer of laminated glass.

Q: Can these racks handle “Jumbo” size sheets (130″ x 204″)?

A: Yes, we offer custom dimensions. For Jumbo sheets, we extend the base and height and increase the number of L-profile uprights to ensure the glass doesn’t bow or flex during transport.

Q: How do you prevent the racks from tipping over when loaded with heavy IGUs?

A: The L-shape design includes calculated counter-balance weights on the back frame. Additionally, the base geometry ensures the center of gravity remains within the footprint even when loaded with high-density double glazing units.

Q: Are the rubber strips replaceable if they eventually wear out?

A: Yes, this is a key advantage of the screw-fixed design. You can simply unscrew the old strip and attach a new steel-core profile in minutes, without scraping off old glue or prepping the surface.

Q: Can these racks be used for stone slabs as well?

A: Absolutely. Many of our clients are stone fabricators. The same protection principles apply to preventing chips on quartz or granite slabs, and the weight capacity is sufficient for stone bundles.
