Is Your "Economy" Rack Cracking Your Premium Slabs? Granite and Quartz are unforgiving. A single hairline fissure caused by poor transport vibration can turn a $2,000 slab into scrap. Stop relying on wooden A-frames and upgrade to industrial steel security designed for the stone yard. |
In the stone fabrication industry, the "death wobble" is the enemy. When transporting 3cm granite or heavy quartz bundles, the center of gravity is dangerously high. Traditional wooden A-frames often flex under the dynamic load of a truck turning corners, causing slabs to slap against each other.
Our Heavy duty L-frame for granite slab transport utilizes a rigid Q235 steel structure with a calculated 90° vertical support combined with a 3-5° safety tilt. This geometry ensures that the slab's dead weight keeps it firmly planted against the back support, utilizing gravity as a stabilizer rather than a liability.
The 3-5° engineered tilt prevents forward tipping while maintaining a compact footprint.
Ask any fabricator about their biggest headache with steel racks, and they will say: "The rubber pads fell off." In a wet saw environment or an outdoor stone yard exposed to UV rays, glue fails. Once the rubber peels, you have Stone-on-Steel contact. The result? Chipped edges and immediate rejection by the homeowner.
We solved this by eliminating glue entirely. Our racks feature Steel-Core Rubber Profiles. A steel insert is vulcanized inside the EPDM rubber, which is then mechanically fastened to the frame with self-tapping screws. The sharp, raw edge of a granite slab can press with tons of force, but it will never cut through this reinforced defense.
Mechanically fixed steel-core rubber ensures zero metal-to-stone contact, even under heavy loads.
If you deliver slabs to job sites or between branches, the return trip is a sunk cost. Standard A-frames take up the same amount of truck space whether they are full or empty.
The "L" in our design stands for efficient logistics. The unique nesting capability allows empty racks to be stacked efficiently. You can fit up to 7 empty racks in the space of 2. This turns a multi-truck recovery operation into a single pick-up run, drastically reducing your fuel and driver costs.
Empty racks nest together like shopping carts, saving 70% of storage and transport space.
Not all stone is created equal. While 2cm marble is fragile, 3cm jumbo quartz slabs are incredibly dense and heavy. A generic "glass rack" might buckle under the concentrated weight of stone.
Our Heavy duty L-frame for granite slab transport is reinforced with 100x50mm rectangular steel tubing at the base to handle loads up to 4 tons (8,800 lbs). Whether you are moving white opaque quartz for a commercial kitchen or delicate onyx for a feature wall, the frame remains rigid, preventing the flex that causes hairline cracks.
Heavy-duty construction supporting dense opaque slab materials without structural deflection.
Q: Can this L-frame hold "Jumbo" size quartz slabs?
A: Yes. We offer extended versions (up to 2032mm/80 inches long) specifically designed to support the full length of Jumbo slabs, preventing overhang warping.
Q: Our stone yard is outdoors. Will these racks rust?
A: For outdoor stone yards, we recommend our Hot-Dip Galvanized finish. It provides a sacrificial zinc layer that prevents rust for 10-20 years, even in wet environments.
Q: How do I move these racks around the fabrication shop?
A: The racks are designed for 4-way forklift entry. They also feature 4 welded lifting eyes at the top for safe movement via overhead bridge cranes.
Q: Will the rubber stain porous stones like white marble?
A: No. We use non-marking, high-density EPDM rubber that does not leach oils or leave black residue on white natural stones.
Q: Can I stack loaded racks?
A: No. Loaded racks must be placed on the floor. Only empty racks are designed to nest and stack for storage efficiency.
