You are losing profit margin on every sheet of Low-E glass that gets scratched by exposed metal during transport. In the high-stakes world of architectural glazing, relying on glue-bonded rubber pads is a liability. Your operation needs a Heavy-duty glass transport trolley engineered with mechanically fixed isolation and Q235 carbon steel stability to ensure the finish quality from the tempering furnace to the job site. |
In a modern glass fabrication facility, the journey from the Glass Tempering Furnace to the installation site is where 90% of damage occurs. We see it constantly: a batch of high-value soft-coat Low-E units is rejected by the glazier because the rubber pads on the transport rack shifted, allowing the glass edge to grind against the steel frame. This "shelling" or coating abrasion isn't just a material loss; it's a schedule killer.
Furthermore, if you are shipping IGU (Insulated Glass Units) or raw laminated sheets using fixed, welded A-frames, you are bleeding cash on reverse logistics. Paying full freight to return empty "air" to your factory is an operational inefficiency that kills margins in a competitive market.
Standard industry racks often use industrial adhesive to attach rubber buffers. In the sweltering heat of a shipping container or the humid environment of a cutting line, that glue degrades. The rubber peels, and your glass meets the steel.
We engineered the Zmgrack customized glass storage rack to eliminate this risk. We use a Flat rubber strip with an internal steel core, anchored directly into the Q235 steel tube using self-threading pins. This mechanical fixation withstands the shear forces of loading 3,300 lbs (1500kg) of glass and remains secure even after years of outdoor exposure. This design guarantees that delicate Low-E glass coatings never touch the structural frame.

Dropping a rack of glass is every warehouse manager's nightmare. It usually happens when a forklift operator misjudges the center of gravity on a generic rack. Our design integrates a standardized, two-way forklift entrance with specific center distances tailored to your material handling equipment.
By physically constraining the fork position, we force the lift equipment to engage the rack at its exact gravitational center. Whether you are moving a Foldable A-Frame Glass Rack fully loaded with heavy architectural curtain walls or maneuvering tight corners in the dispatch zone, the risk of tipping due to the "lever effect" is structurally negated.
Engineered forklift channels prevent operator error and stabilize heavy glass loads during transport.
The math is simple: Why use five trucks to return empty racks when you could use one? The Zmgrack functions as a collapsible glass stillage. Once the glaziers have offloaded the units at the construction site, the A-frames can be dismantled and folded flat in under a minute.
The base and uprights nest perfectly, allowing you to stack empty racks with extreme density. This 5:1 compaction ratio slashes your reverse logistics fuel costs by 80%. For exporters, this means fitting up to 60 units in a single 40HQ container, making the loop between the glass factory and the overseas distributor economically viable.
Folded flat state: Compressing bulk to maximize container space and minimize return freight costs.
Not every job is a standard window. Commercial projects often involve oversized curtain walls or long strip windows. Traditional closed-end A-frames restrict you to the rack's physical length. Our flat glass racks feature an open-ended design. While the footprint is a compact 86" x 75" (2200x1900mm), the lack of side obstructions allows for the safe storage of 12-foot or even 20-foot (6 meter) lineal extrusions and glass sheets, provided they are balanced correctly.
Q: What is the static load capacity for these racks?
A: The system is rated for a static load capacity of 3,300 lbs (1500kg). It uses Q235 high-strength carbon steel square tubes to ensure zero frame deflection, which is critical to preventing stress fractures in stacked glass.
Q: Can this rack handle "Jumbo" size glass sheets?
A: Yes. The open-sided design allows for glass sheets longer than the rack itself (up to 6 meters/20 feet) to be stored, making it ideal for curtain wall units and oversized storefront glazing.
Q: Will the rubber pads leave residue on Low-E coatings?
A: No. We use high-quality, non-marking rubber that is mechanically screwed into the frame. Unlike glued pads that degrade and slip, our system ensures no metal-to-glass contact, preventing coating scratches and contamination.
Q: How many folded racks fit in a shipping container?
A: The high-density nesting design allows you to load approximately 60 sets of the Demountable A-Frame Rack into a standard 40HQ container, significantly reducing per-unit shipping costs.
Q: Is the surface treatment suitable for outdoor storage at construction sites?
A: Absolutely. While electrostatic spraying (powder coating) is standard, we highly recommend Hot-dip Galvanizing for racks used in outdoor or maritime environments to provide long-term corrosion resistance against rain and humidity.
