Stop sacrificing your margins to edge chipping and inefficient warehouse logistics. For high-volume distributors handling Wholesale Tempered Glass and IGUs, the bottleneck isn't production—it's storage and transport. Our L-Shape Glass Holding Racks are engineered to maximize density and eliminate "metal-on-glass" contact, ensuring your inventory arrives at the job site exactly as it left the tempering furnace. |
In the architectural glass industry, particularly for distributors serving the frantic pace of the California or New York markets, the "Standard A-Frame" often becomes a liability. When you are moving hundreds of sheets of 1/4 inch tempered glass or heavy laminated glass panels daily, static racks that occupy premium warehouse space when empty are a drain on profitability. Furthermore, the dreaded "edge shell" caused by poor padding can turn a profitable custom shower enclosure order into a remake nightmare.
We engineered the Grack series not just as a shelf, but as a heavy-duty glass rack system designed to withstand the rigors of the supply chain, from the float line to the glazing contractor's truck.
The Pain Point: You send a truckload of glass to a job site or a window fabricator. The glass is offloaded. Now, your driver is hauling back a trailer full of air because the empty A-frames take up the same footprint as full ones. This inefficiency doubles your freight cost per unit.
Our Solution: The Grack features a calculated L-shape geometry with an offset base design. This allows empty racks to "nest" into one another, similar to shopping carts but for heavy industry. You can stack 7-10 empty racks in the space of 2-3 full ones. This capability transforms them into highly efficient returnable shipping racks, reducing return freight volume by over 70%.
Empty nesting capability dramatically reduces warehouse footprint and return logistics costs.
The Pain Point: In the heat of a container or an outdoor yard, the adhesive on standard rubber pads fails. The rubber peels off, exposing the steel frame. When a 200lb sheet of Insulated Glass Unit (IGU) settles against bare steel during transport, the vibration creates stress points that lead to immediate breakage or delayed "spontaneous" shattering.
Our Solution: We utilize a proprietary Steel-core rubber profile. This isn't just rubber glued to metal; it is a rubber extrusion with a steel insert, mechanically fastened to the rack frame with self-tapping screws. It cannot peel, slip, or degrade under the weight of Jumbo sheets. This ensures that your high-value Low-E coated glass never touches the frame, preventing coating scratches and edge damage.
Steel-core rubber profiles mechanically fastened to ensure zero metal-on-glass contact for IGUs.
The Pain Point: Many generic racks are built with thin-wall tubing to save cost. When loaded with 4,000 lbs of architectural glass, these racks flex. Glass is rigid; racks cannot be flexible. If the rack twists during a forklift movement, the glass takes the torque, resulting in catastrophic failure.
Our Solution: We use Q235 Carbon Structural Steel with full seam welding (no stitch welding). The base utilizes 100x50mm rectangular tubing to handle the torque of forklift operations. Whether you are storing float glass sheets or heavy stone slabs, the 90-degree vertical support with a 3-5 degree safety tilt ensures the load remains static and secure, even over rough terrain.
Heavy-duty construction capable of handling Jumbo size architectural glass without structural flex.
Efficiency in a glass fabrication plant is defined by flow. The Grack is designed to move. With 4-way forklift entry and overhead crane lifting lugs, this rack serves as a universal carrier. It can receive glass directly from the tempering line, move to the curing area, be loaded onto a glass truck delivery system, and be dropped at the construction site without the glass ever being touched by hand. This "One-Touch" logistics model significantly reduces labor costs and handling risks.
Engineered with 4-way forklift channels for seamless integration into factory and site logistics.
Q1: Can these racks handle different sizes of glass simultaneously?
A: Yes. The L-Shape design with a solid base allows for mixed loads. However, for transport safety, we recommend placing larger Jumbo sheets at the back and smaller units like shower doors or window panes at the front, secured with ratchet straps.
Q2: What is the weight capacity for the standard L-Shape rack?
A: Our standard heavy-duty model is rated for 3,300 lbs (1.5 Tons) to 8,800 lbs (4 Tons) depending on the configuration and tube thickness selected. This is sufficient for dense packs of laminated glass or granite slabs.
Q3: How many empty racks can fit in a standard 40HQ container?
A: Thanks to the nesting design, we can fit approximately 98 to 112 units of the standard size (1600x950x1600mm) into a 40HQ container. This dramatically lowers your landed cost per unit compared to non-nesting A-frames.
Q4: Will the rubber padding damage soft-coat Low-E glass?
A: No. We use high-quality EPDM or Polyurethane rubber with a Shore A hardness of 70-80. It provides grip and cushion without marring sensitive coatings. The mechanical fastening ensures no screw heads ever contact the glass surface.
Q5: Can I use these racks for on-site delivery to glazing contractors?
A: Absolutely. This is their primary use case. The racks are designed to be lifted by crane to upper floors or moved by rough-terrain forklifts on construction sites, making them ideal for curtain wall engineering projects.
