Are remakes from scratched Low-E coatings and micro-cracks on thin lites eating into your margins? Is your shop floor clogged with unstable, oddly-sized glass moving from the CNC cutting table to the tempering line? Stop wrestling with A-frames that weren't designed for sorting and in-process flow. It's time to break the cycle of inefficiency and product damage.
The Problem (Before): A short, high architectural lite comes off the cutting table. On a standard roller-base rack, it only makes contact with one or two rollers, making it dangerously unstable during transport.
The Engineering (Why it Works): Our full base harp racks feature a continuous, slotted steel base. This design provides edge-to-edge support along the entire bottom of the glass, regardless of its length. The lite rests securely along a complete line, eliminating the risk of tipping associated with short-contact-point systems.
The Result (After): You can confidently handle any custom-cut dimension, from small decorative pieces to tall, narrow panels, drastically reducing the risk of breakage during in-plant transfer and expanding the range of jobs you can take on without custom rigging.
The Problem (Before): Expensive Low-E or digitally printed glass gets surface scratches from contact with metal dividers. Thin glass for Insulated Glass Units vibrates in oversized 1/2" slots, causing edge chipping and hidden fractures that lead to costly remakes.
The Engineering (Why it Works): Each steel divider is fully encased in a soft, non-abrasive PVC casing. This creates a cushioned slot that protects delicate coatings. Furthermore, we offer custom slot widths. For an Insulated Glass Unit Manufacture working primarily with 1/4" glass, we can produce a rack with 3/8" (approx. 10mm) slots, providing a snug, secure fit that eliminates all movement.
The Result (After): A near-zero rate of surface-related defects. Your high-value lites arrive at the IGU assembly or tempering line in perfect condition, protecting your materials investment and your reputation for quality.
The Problem (Before): An operator is loading a heavy lite onto a mobile rack. The rack shifts slightly, causing the glass to slam against the backstop or, worse, injure the worker.
The Engineering (Why it Works): Our harp rack glass trolley features a unique foot-actuated lifting and locking mechanism. Before loading or unloading, the operator simply steps on a pedal. This lifts the glass load slightly off the base support and presses it securely against a fixed rubber buffer while also locking the rack in place. The entire load is immobilized.
The Result (After): A dramatic increase in operational safety. Glass is completely stationary during handling and secured against all movement during transport, virtually eliminating the risk of accidents and load shifting, even over uneven shop floors.
We understand the demanding environment of a glass plant and the logistics of international business. That's why every heavy duty glass transport rack is constructed from high-tensile Q235A Carbon Steel with a full welding process for maximum structural integrity. But strength doesn't mean inconvenient logistics. The entire unit is designed with a knock-down bolted assembly. It ships flat-packed, drastically reducing freight volume. This makes a huge difference in the cost of a full container load, delivering a superior product to your door for less.
| Model/SKU | External Dimensions (L×W×H, Inches) | Slot Count | Applicable Glass Thickness (Inches) | Dynamic Load (Lbs) |
| HR-40 | 59" × 39.4" × 71" | 40 | ≤ 1/2" | 3300 |
| HR-84 | 59" × 47.2" × 70.9" | 84 | 0 - 5/16" | 3300 |
| HR-40 (Narrow) | 39.4" × 47.2" × 70.9" | 40 | 5/16" - 1/2" | 3300 |
| Custom Large | 102.4" × 94.5" × 74.8" | 80 | ≤ 1" | >5500 |
The best method is to use a harp rack with a custom slot width that is slightly larger than the glass thickness (e.g., 8-10mm for 6mm glass). This provides a snug fit, preventing the lites from vibrating or rattling during movement, which is the primary cause of micro-cracks and edge damage in thin glass.
A harp rack for sorting glass units is ideal for IGU production. Its numerous, individually accessible slots allow operators to "kit" or "pair" the specific lites needed for an assembly. The entire organized kit can then be safely wheeled directly to the IGU line, dramatically speeding up the pairing process and reducing handling errors.
Absolutely. The dividers are coated with a soft, durable PVC casing. This non-abrasive surface is specifically designed to protect sensitive coatings like Low-E from scratches, ensuring that your most valuable products remain pristine throughout the production process.
The knock-down design allows the rack to be shipped in a "flat-pack" configuration. This significantly reduces the shipping volume compared to a fully welded unit. For international clients or those ordering in bulk, this means more units can fit into a single shipping container, substantially lowering per-unit freight costs.
Dynamic load (e.g., 3300 Lbs) is the maximum weight the rack can safely hold while it is being moved around your facility. Static load, which is always higher, is the maximum weight it can hold while stationary. It is critical to always adhere to the dynamic load capacity for operational safety.
