Is your transit damage eating into your margins? |
In the glass distribution business, particularly when hauling heavy crates of wholesale tempered glass or oversized Insulated Glass Units (IGU), the stresses placed on your logistics equipment are immense. A standard truck hitting a pothole at 50 mph sends a shockwave through the chassis directly into your racks.
If you are using generic racks fabricated with simple spot welding (stitch welding), you are sitting on a ticking time bomb. Spot welds create stress concentration points. Over time, the dynamic loads from transporting 4,000 lbs of glass cause fatigue cracks. Once a weld fails, the rack loses rigidity, leading to "rack twist." The result? Your glass sheets flex against each other, causing catastrophic shell chips or run/vent cracks before the truck even reaches the job site.
Full seam welding ensures structural continuity, preventing fatigue cracks during transport.
To guarantee zero structural failure over a 10-year lifespan, our heavy duty glass rack systems utilize a full seam welding process on all Q235 carbon steel joints.
Unlike spot welding, full seam welding fuses the metal along the entire joint length. This distributes the weight of jumbo monolithic sheets or heavy stone slabs evenly across the frame, eliminating weak points.
For outdoor storage or open-bed truck transport, unsealed gaps in stitch welds allow water to enter the tubing. This causes internal rust (corrosion from the inside out), which compromises the rack's strength without being visible until it collapses. Our full welds seal the tubes completely.
Designed to handle heavy structural glass and curtain walls without deformation.
Durability isn't just about the steel; it's about the interface between the steel and your glass. A common failure point in cheap glass transport racks is the rubber padding. Traditional glued rubber strips peel off under the shear force of loading and unloading, or degrade under UV exposure.
Once the rubber is gone, you have "metal-on-glass" contact. For tempered glass, edge contact with steel guarantees an explosion. Our solution is the Steel-Core Rubber Profile. We embed a steel plate inside the EPDM rubber and mechanically fasten it to the rack with self-tapping screws.
Steel-core rubber ensures the glass edge never touches the metal frame.
For wholesale distributors shipping to other states, the cost of returning empty racks is a major profit leak. Traditional A-frames are bulky and take up the same floor space empty as they do full.
Our L-Shape Glass Holding Rack is designed with a specific geometric offset that allows empty racks to "nest" into one another—similar to shopping carts. This reduces the volume of empty racks by up to 70%, significantly lowering freight costs for return trips.
Maximize truck space on return trips with high-density nesting.
Whether you are handling 1/4 inch tempered glass, laminated sheets, or finished window units, the durability of your racking system is the foundation of your logistics. By choosing full seam welded structures with mechanically fastened protection, you eliminate the risks of weld fatigue and rubber delamination. Don't let a cheap rack ruin a shipment of high-value architectural glass.
Q: Can these racks handle 130" Jumbo glass sheets without tipping?
A: Yes. Our racks are engineered with a calculated center of gravity and include rear balance blocks (counterweights) to ensure stability even when loaded with high-center-of-gravity Jumbo sheets.
Q: Do you offer protection for Low-E coatings?
A: Absolutely. The EPDM rubber we use is non-marking and formulated to be soft enough to prevent scratches on sensitive Low-E coatings while hard enough (Shore A 70-80) to support the glass weight.
Q: How many empty L-racks fit in a standard truck?
A: Thanks to the nesting design, you can stack roughly 3 to 4 times more empty racks compared to non-nesting A-frames. A 53' truck can typically return over 60-80 nested units depending on the model.
Q: Is Hot-Dip Galvanizing necessary for indoor use?
A: For purely indoor warehouse use, our electrostatic powder coating (RAL 5010) is sufficient. However, if the racks will be used for jobsite delivery or stored in outdoor yards, we highly recommend Hot-Dip Galvanizing for 20+ years of rust protection.
Q: Can I replace the rubber pads if they eventually wear out?
A: Yes. Since we use screws instead of glue, you can simply unscrew the old rubber profile and attach a new one in minutes, without needing to scrape off old adhesive or prep the surface.
