Your tempering furnace output shouldn't be bottlenecked by inadequate logistics. Whether you are moving delicate Low-E coated units or heavy laminated structural glass, the difference between profit and a "shelling" claim lies in your choice of transport equipment. Stop paying to ship air on return trips and eliminate edge damage with a rack engineered for the modern glass supply chain. |
In the architectural glass sector, "standard" sizes are becoming a thing of the past. Facade projects increasingly demand jumbo sheets or long, irregular curtain wall units exceeding 12 feet (3.6 meters). Traditional fixed A-frames often feature closed side beams, making them physically incompatible with these lengths.
The Heavy-duty glass transport rack (Zmgrack) utilizes a completely open-ended geometry. While the rack's physical footprint is a compact 86" x 75" (2200mm x 1900mm), the absence of vertical side restrictions allows extensive overhang. This means a single rack inventory can handle standard window units today and 20-foot commercial facade panels tomorrow, without requiring a custom fleet for every project.

For Supply Chain Directors, the "hidden tax" of glass logistics is the return trip. Once your fleet drops off the glass at the glazing site, driving empty fixed racks back to the plant is a financial sinkhole. You are essentially paying fuel and driver hours to transport air.
By switching to a Foldable A-Frame Glass Rack, you unlock a 5:1 folding ratio. In a practical scenario, a 40HQ container that ships out with 20 loaded racks can return with 60 folded empty racks. This drastically reduces the number of return trucks required, slashing your reverse logistics costs by up to 80%. This isn't just a rack; it's a cash-flow liberation tool.

One of the most frequent causes of rejection for high-value Low-E glass is surface scratching caused by metal contact. This often happens when the rubber pads on a rack peel off—a common failure in glued systems when exposed to the heat of a shipping container or the cutting fluids in a workshop.
We have engineered this risk out of the equation. Our Demountable A-Frame Rack features a proprietary steel-core rubber strip that is mechanically anchored into the Q235 steel frame using self-threading pins. This physical bond ensures that even under extreme heat or friction during loading/unloading, the rubber never delaminates. Your glass never touches raw metal, preserving the integrity of soft coatings and edges.

A 3,300 lbs (1500kg) load of glass creates a dangerously high center of gravity. If a forklift operator misaligns the forks during a rush at the loading dock, the risk of tipping is catastrophic—posing severe OSHA compliance risks and destroying the product.
To mitigate this, the Zmgrack integrates standardized, reinforced forklift entrances with specific center distances tailored to industrial handling equipment. These channels force the forklift tines to align with the physical center of the load, neutralizing the lever effect and ensuring stable dynamic movement over uneven concrete floors or ramp transitions.

Q: What is the exact static load capacity for jumbo sheets?
A: The system is rated for a static load capacity of 3,300 lbs (1500kg). The Q235 carbon steel frame is engineered to minimize deflection, ensuring that the glass packs do not flex or suffer from torque stress during storage or transport.
Q: Can this rack handle raw float glass and IGU units simultaneously?
A: Yes. The 3-5 degree tilt angle is optimized for both raw glass packs and finished Insulated Glass Units (IGU). The rubber lining protects the sealants and edges of finished units just as effectively as raw sheets.
Q: How many folded racks can fit in a standard 40HQ container?
A: Due to the nesting design, you can load up to 60 sets of empty, folded Zmgracks into a single 40HQ container. This makes it an ideal solution for closed-loop supply chains between manufacturing plants and distribution centers.
Q: Will the steel frame rust if stored outside in a glass yard?
A: Standard units come with electrostatic spraying. However, for outdoor storage or maritime shipping environments, we strongly recommend our Hot-Dip Galvanized option. This creates a metallurgical bond that provides sacrificial anode protection against corrosion and rust for 15-20 years.
Q: Can the forklift pocket dimensions be customized for our specific side-loaders?
A: Absolutely. While we have a standard spec, as a manufacturer, we can adjust the fork entrance size and center distance to match your specific fleet of forklifts, side-loaders, or pallet jacks.
