Eliminate Scratches on High-Value Coated GlassYour tempering furnace and CNC lines are running at capacity, but your reject rate due to surface scratches during WIP transfer is eating into your margins. For custom fabricators handling soft-coat Low-E or heavy laminated architectural glass, standard A-frames aren't enough. You need a dedicated sorting system that isolates every single sheet. |
In a high-output glass fabrication facility, the zone between the CNC cutting table and the tempering furnace or IGU line is often where chaos happens. Operators are manually handling expensive sheets, trying to sort them for "pairing" before they hit the washer. If you are using static A-frames or leaning glass against walls, you are risking domino-effect breakage and coating damage.
The Glass Separator Rack, widely known in the industry as a Harp Rack, is engineered specifically to solve this sorting logistics problem. Unlike bulk storage racks, this unit is designed for the individual isolation of glass units.
PVC-coated dividers ensure zero metal-to-glass contact, critical for soft-coat Low-E glass.
For fabricators like Glasswerks who deal in high-performance energy-efficient glass, preserving the soft coating is non-negotiable. Even microscopic friction from stacking glass sheets together can ruin a batch. Our Glass Separator Rack features high-tension steel rods encapsulated in industrial-grade PVC tubes. This ensures that the face of the glass never touches a hard surface, and—more importantly—never touches another piece of glass. The rack acts as a buffer, maintaining the pristine quality of the glass surface from the breakout table to the sealing robot.
Efficiency in Insulated Glass Unit (IGU) manufacturing comes down to how fast you can pair the inner and outer lites. A chaotic floor leads to downtime at the press.
High-contrast numbered slots allow operators to sequence glass pairs perfectly for the IG line.
This system features a numbered slotting system (1-40 or customized) on the base. This allows the cutting table operator to sequence the glass perfectly: Slot 1 for the outer lite, Slot 2 for the inner lite. When the rack is wheeled to the washer or assembly line, the pairing is already done. The integrated High-Density Nylon Rollers on the base mean your operators aren't lifting heavy architectural glass; they are sliding it. This significantly reduces operator fatigue and back injuries associated with manipulating heavy laminated or thick float glass.
Moving 2,000 lbs of glass across a factory floor requires more than standard casters. If a rack shifts while an operator is loading a heavy sheet of laminated security glass, the results can be catastrophic.
The foot-actuated lifting mechanism locks the rack firmly to the floor during loading.
Our Glass Separator Rack is equipped with a Foot-Actuated Lifting Mechanism. With a simple step, the operator can raise the rack off its wheels, planting it firmly on static pads. This ensures absolute stability during the loading and unloading process. Once loaded, the heavy-duty polyurethane casters (two swivel with brakes, two fixed) ensure smooth transit over expansion joints and rough concrete floors common in fabrication plants.
We understand that shipping large welded structures is costly. That is why our racks utilize a Bolted Assembly (Knock-Down) design. We ship them flat-packed, allowing you to fit significantly more units into a container, reducing your landed cost per unit. Assembly on-site is straightforward, requiring standard tools.
Flat-pack design minimizes shipping volume and costs.

1. Can this rack handle heavy laminated glass or just standard float glass?
Yes, the rack is engineered with Q235A Carbon Steel and features a heavy-duty base. It is specifically designed to handle the weight of laminated and thick architectural glass. The nylon rollers facilitate the sliding of these heavy sheets without physical strain.
2. Will the dividers scratch Soft-Coat Low-E glass?
No. The "strings" of the Glass Separator Rack are steel rods covered in a thick, industrial-grade PVC casing. This provides a soft, non-abrasive barrier designed specifically to protect sensitive coatings like Low-E.
3. Can we customize the slot width for thicker IGU units?
Absolutely. While standard harp racks are often used for single lites (monolithic), we can customize the spacing between the rods to accommodate thicker sealed Insulated Glass Units (IGUs) if you need to use the rack for curing or transport after sealing.
4. How does the numbering system help my production flow?
The numbered slots (typically 1-40 or 1-84) allow your CNC cutting team to organize glass sequentially. For example, odd numbers can be assigned to the exterior lite and even numbers to the interior lite. This means when the rack arrives at the IGU line, the glass is already pre-sorted and ready for pairing, eliminating confusion and manual re-sorting.
5. Is the rack stable enough to be moved by a forklift?
Yes. The base is designed with forklift pockets (forklift entrance) for safe lifting when the rack is fully loaded or needs to be moved between different buildings in your facility.
