Fabricating Quartz, Granite, or Marble slabs requires equipment that goes beyond standard specifications. The density of stone puts significantly more stress on welds and joints than standard glass sheets. |
Stone slabs are unforgiving. A 3cm thick slab of granite weighs significantly more per square foot than standard glazing. When you load a rack with multiple slabs of quartz, the gravitational force exerts immense pressure on the bottom "A" joint.
Cheaply made racks often use "spot welding" or thin-gauge steel to save costs. Under the static load of heavy stone, these weak points can fracture, causing the A-frame to splay open or collapse—a catastrophic event in any workshop. We utilize Q235 Square Steel Tubing, a material chosen specifically for its high yield strength and ability to withstand the extreme dead loads of the stone industry.
As shown in the image above, the strength of a Granite Transport Rack starts at the base. Our design features a reinforced, double-beam base structure that resists twisting (torsion) when the rack is lifted by a forklift or crane.
This rigidity is crucial when moving across uneven terrain at a job site. If the base flexes, the stone slabs can shift and crack. By creating a rigid, non-flexing platform, we ensure that your high-value inventory—whether it's a Calacatta Gold marble slab or a ballistic glass unit—remains completely stable during handling.
Many modern fabricators are expanding their portfolios, handling both Glass Backsplashes and Stone Countertops. Running two different types of racking systems is inefficient and takes up valuable floor space.
Our A-Frames serve as a universal solution. The same industrial rubber profiles that protect soft-coat Low-E glass are durable enough to cushion heavy stone slabs without compressing or tearing. This "One Rack, All Materials" approach simplifies your logistics, allowing you to use the same fleet of racks for every project, regardless of the material.
1. Can I use these racks for both glass and stone simultaneously?
Yes, provided you balance the weight distribution. The rubber lining is safe for both materials, but we recommend loading heavy stone closer to the center uprights for optimal stability.
2. What is the load capacity rating for stone applications?
Our Heavy Duty models are rated for up to 2000kg (4400 lbs) per side, specifically engineered to handle full bundles of 2cm or 3cm granite slabs.
3. How do you prevent stone slabs from tipping forward?
We supply adjustable Safety Retention Poles (Limit Bars) that slot into the base. These bars physically prevent the outermost slabs from tipping, acting as a fail-safe during strap release.
4. Is the rubber padding resistant to water and stone slurry?
Yes. The industrial rubber compound is non-porous and water-resistant, meaning it won't rot or degrade when exposed to the wet conditions typical in stone fabrication shops.
5. Do these racks work with standard stone clamps and lifters?
The A-Frame design leaves the top of the slabs open and accessible, allowing for easy clearance when using overhead slab lifters or vacuum manipulators to load and unload.
