In the humid environment of a glass processing plant—between the spray of the edging machine and the steam of the washing line—rust is your inventory's worst enemy. Standard painted racks chip, rust, and eventually drip iron oxide onto your premium Low-E coatings, turning high-value architectural glass into scrap. Our Hot-Dip Galvanized A-Frames are engineered to survive decades of wet processing and outdoor site exposure without compromising your glass quality. |
For any glazier or fabricator dealing with wholesale float glass or sensitive Low-E coated sheets, surface integrity is non-negotiable. Traditional powder-coated racks inevitably fail at the weld points due to the constant friction of loading and unloading. Once the steel is exposed to the moisture inherent in the glass tempering and washing workflow, oxidation begins.
Our Hot-Dip Galvanized A-Frames undergo a metallurgical bonding process where the entire steel structure is submerged in molten zinc. This isn't just a surface paint; it's a cathodic protection system. Even if the surface is deeply scratched by a forklift tine or a heavy granite slab, the surrounding zinc sacrifices itself to protect the steel, ensuring no rust water ever drips onto your stacked Insulated Glass Units (IGUs) waiting for shipment.
Built for the elements: Galvanized racks deployed in outdoor storage yards.
Whether you are moving 19mm toughened glass or heavy crates of laminated glass, the structural failure of a rack is a catastrophic safety event. Unlike cheap competitors who rely on spot welding (which creates stress points prone to tearing), Mgrack utilizes a Full Seam Welding process on high-grade Q235 steel.
The geometry of our Hot-Dip Galvanized A-Frames is calculated to lower the center of gravity, preventing tipping even when loaded unevenly—a common scenario when picking specific sheets for the CNC cutting table. The base profiles are reinforced to handle the dynamic loads of transport trucks and rough construction site terrain.
Reinforced lifting eyes for safe overhead crane maneuverability.
For international glass distributors or processors importing equipment, shipping "air" inside a container kills profitability. A fully welded, fixed A-frame takes up massive volume.
Our solution is the detachable, flat-pack design. We can fit dozens of disassembled units into a single container, drastically reducing your landed cost per unit. Once unloaded, they can be assembled quickly with high-strength bolts. Furthermore, when not in use or during return logistics from a job site, the empty racks can be stacked compactly, freeing up valuable floor space in your glass factory for active production lines like your double glazing assembly area.
Maximize your warehouse density: 8 units folded and stacked efficiently.
The strongest steel frame is useless if it chips the edges of your glass. We integrate a comprehensive protection system designed specifically for the glazing industry.

1. Will the hot-dip galvanization affect the tolerances for my automated loading systems?
No. While hot-dip galvanizing adds a microscopic thickness to the steel, our engineering accounts for this. We ensure that critical dimensions for automated grabs or robotic loading arms remain within the required tolerance range.
2. Can these racks handle Jumbo size (6000mm x 3210mm) sheets?
Yes, we manufacture specific heavy-duty variants designed for Jumbo sheets commonly used in commercial curtain walls. These feature reinforced base channels and additional vertical supports to prevent glass deflection.
3. How do you prevent "white rust" on the galvanized racks during ocean shipping?
Proper passivation and ventilation are key. We ensure the galvanized coating is fully cured and passivated before packing. We also use moisture-absorbing desiccants inside the shipping container to control humidity levels during transit.
4. Are the rubber pads compatible with soft-coat Low-E glass?
Absolutely. We use non-marking, formulated rubber compounds specifically tested to ensure they do not react with or mar the metallic oxide layers of high-performance Low-E coatings.
5. What is the typical lifespan of a hot-dip galvanized rack in a wet glass factory?
In a standard industrial environment, hot-dip galvanization can provide maintenance-free protection for 20 to 50 years. Even in aggressive wet environments typical of glass grinding and washing areas, they significantly outlast painted or spray-galvanized alternatives.
