China G603 Sesame White Granite Suppliers, Factory
Product Description
Product Information
Supply Advantage: Continuous vein deposits with ultra-large reserves, stable annual production capacity, capable of undertaking overseas projects spanning millions of square metres.
- Base Colour: Pure off-white/snow white with minimal colour variation and high consistency.
- Veining: Fine speckled texture with minute, uniformly distributed black/dark grey mineral particles; no coarse or chaotic patterns; overall refined and clean appearance.
- Comparison with G602: G603 exhibits fine grain, whereas G602 displays coarse grain; G603 is whiter and more uniform, while G602 features a more rugged texture; G603 is better suited for interior and premium exterior applications.
- Gloss: Polished finish achieves ≥90° gloss level with pronounced mirror-like sheen; flame-finished/lychee surfaces present uniform matt finish, offering slip resistance without glare.

Frequently Asked Questions
G603 features a fine grain, smaller mineral particles, and a cleaner snow-white base colour, making it ideal for high-end interior finishes and premium exterior cladding. In contrast, G602 has a coarse-grained, large-flower texture tending towards greyish-white, which is typically selected for lower-cost outdoor paving and municipal landscaping.
G603 boasts a density of 2.68 g/cm³, a water absorption rate of ≤0.25%, a compressive strength of 150–170 MPa, and a Mohs hardness of 6.5–7. It complies with ASTM C615 and CE EN 1341 standards, guaranteeing frost resistance and no yellowing or weathering for over 20 years outdoors.
Common finishes include Polished (POL, ≥90° gloss level for walls and worktops), Flamed (FLM, slip-resistant for outdoor plazas), and Bush-hammered (BHM, uniform pitted texture for landscaping). Honed, Pineapple, Natural, Sandblasted, and Waterjet mosaic finishes are also available.
Big slabs are available in 2400×1200mm and 2600×1300mm with thicknesses of 16mm, 18mm, 20mm, and 30mm. Standard tiles include 600×600mm, 800×800mm, and 300×600mm with thicknesses from 15mm up to 30mm. Custom kerbstones and architectural shapes are made to order.
The HS codes are: 25161100.00 for rough blocks, 25161200.00 for rectangular slabs/blocks, 68022390 for polished finished slabs, and 68029190 for custom carved shapes. Export shipments include Class A radioactive testing reports, Certificate of Origin, Packing List, and Commercial Invoice.
The Minimum Order Quantity is 50m² for slabs and 100m² for project panels. Standard orders are ready to ship within 7–15 days (or 15–20 days depending on processing complexity), with batch delivery options available for large-scale developments.
