transport granite a-frame,a frame for granite slabs sd903
The SD903 frame uses CNC-welded joints throughout — every structural connection is a continuous weld bead, not a bolt and washer. This doubles the load rating compared to bolt-together designs.
SD903 Product Overview
The SD903 contact pads are made from EPDM rubber — the same material used in permanent outdoor gaskets. They won’t degrade, stain, or transfer color to light-colored stone surfaces.
Natural stone slabs are heavy, irregular, and expensive to replace. The SD903 was engineered around those realities — load-tested to 120kg per slot with a safety factor of 2.5.
We manufacture the SD903 with frame tolerances borrowed from industrial pallet racking. Not because display stands belong in warehouses, but because wobbling is unacceptable when presenting a $3,000 marble slab.
Natural stone varies in thickness from 10mm to 30mm, and your display rack must handle that range. The SD903 slots accept the full thickness spectrum without adapter plates or shims.
Key Features
- Adjustable slot depth for stone thickness from 10mm to 30mm without adapter plates
- Modular bolt-together frame for infinite row extension
- Full-frame gusset plates at all four corners for lateral load handling
- Powder coat applied at 90-110μm thickness — over triple the industry minimum
- Center of gravity engineered 40% below frame midpoint for natural stone weight distribution
- All structural members available with mill test certificates on request
- Reinforced lower tiers with additional cross-bracing for the heaviest slabs
- Load-tested to 120kg per slot with published safety factors

Common Questions
How long does delivery take?
Standard models in stock ship within 7 business days. Custom orders typically require 15-25 business days for production. Sea freight transit varies by destination — most ports in Europe, the Americas, and Southeast Asia receive shipments within 25-35 days after departure.
How is the rack packaged and shipped?
Steel components are foam-wrapped and packed in reinforced export cartons or plywood crates depending on order volume. We ship via sea freight FOB Xiamen, air freight, or international courier. You are welcome to use your own forwarder as well.
What surface finishing options are available?
Standard is matte black powder coating with acid pickling and anti-rust treatment. We also offer custom RAL color matching, chrome plating, and specialized coatings for outdoor or high-humidity environments.
What materials can the SD903 hold?
The SD903 is designed around natural stone and marble samples. Share your sample dimensions and weight with our team, and we will confirm compatibility — usually within one business day.
Do you offer design assistance for showroom layouts?
Yes. Send us your floor plan with dimensions and our team will propose a rack configuration that balances product density with customer flow. This service is included at no charge for any order inquiry.
