Every granite procurement decision starts with a datasheet. Numbers like 2.7 g\/cm³<\/strong> or ≤0.4% water absorption<\/strong> are not marketing fillers — they are the figures that decide how a facade performs ten years after installation. Yet many contractors sign contracts without fully understanding what those values mean, or whether the supplier behind them can actually guarantee them. This guide walks through the key technical specifications of G682 golden granite (also known as Golden Rust or Yellow Rust granite) from Suizhou, China, and explains what each one means for your project.<\/p>\n

Density: ~2.7 g\/cm³ and What It Means for Your Structure<\/h2>\n

G682 has a bulk density of approximately 2.7 g\/cm³, which is standard for high-quality granite. For facade engineering, density translates directly into dead load<\/strong>. A 30 mm thick panel weighs roughly 80 kg per square meter — a figure your structural engineer will use to size brackets, anchors and the sub-frame. Heavier panels also affect site logistics: hoisting capacity, storage racks and handling equipment must all be planned around this weight. When a supplier’s datasheet shows a density well below 2.6 g\/cm³, it can signal excessive porosity or inconsistent quarry material, both worth questioning.<\/p>\n

Compressive Strength: 110–150 MPa<\/h2>\n

With compressive strength between 110 and 150 MPa, G682 comfortably handles demanding applications beyond curtain wall cladding: ground-level columns, stair treads, kerb stones and paving in high-traffic areas. For procurement teams, this range also says something about batch consistency<\/strong>. Granite from a single, well-managed quarry shows stable test results across lots; wide variation between shipments is a red flag for mixed or poorly sorted material.<\/p>\n

Water Absorption: ≤0.4% — The Number That Protects Your Facade<\/h2>\n

This is arguably the most important figure for exterior cladding. Water absorption at or below 0.4% means the stone takes up very little moisture, which delivers three practical benefits: fewer stains<\/strong> from rain and runoff, better freeze-thaw performance<\/strong> in cold climates, and reduced efflorescence<\/strong> and salt crystallization on the surface. Compare that with softer stones such as limestone or some sandstones, where absorption above 3% leads to weathering, color drift and ongoing maintenance costs. For coastal or high-humidity projects in Southeast Asia and the Gulf, low absorption is non-negotiable.<\/p>\n

Freeze-Thaw Resistance: More Than 200 Cycles<\/h2>\n

G682 withstands more than 200 freeze-thaw cycles in laboratory testing. Buyers in Korea, Northern China and Europe should treat this as a baseline requirement for any exterior stone. Projects in the Middle East face a different enemy: intense thermal cycling and UV exposure rather than frost. G682’s stable mineral composition and warm yellow tone hold their color under years of strong sunlight, which is why it remains a preferred choice for Saudi and UAE facade packages.<\/p>\n

Mohs Hardness 6–7: Built for Traffic<\/h2>\n

On the Mohs scale, G682 reaches 6–7 — hard enough to resist scratching in hotel lobbies, commercial walkways and public plazas. For flooring and stair applications, this means polished and honed surfaces keep their finish longer, reducing life-cycle maintenance budgets for owners.<\/p>\n

GB 6566 Class A: Compliance Without Restrictions<\/h2>\n

Natural stone buyers increasingly ask about radioactivity. G682 is classified Class A under GB 6566<\/strong>, the Chinese national standard for building materials radioactivity — the least restrictive category, suitable for unrestricted use in both interior and exterior applications. This classification simplifies import documentation and answers the compliance questions that often come up in government and large commercial tenders.<\/p>\n

How to Verify a Supplier’s Numbers<\/h2>\n

Datasheets are only as reliable as the quarry and factory behind them. Before awarding a package, we recommend three steps: (1)<\/strong> request recent laboratory test reports covering water absorption, compressive strength and freeze-thaw performance; (2)<\/strong> arrange third-party inspection (SGS, BV or your appointed inspector) if the project specification requires it; (3)<\/strong> test a sample panel from the actual production batch, not a showroom piece. A supplier with its own quarry and in-house processing can trace every panel back to the block — that is the level of control that makes datasheet numbers repeatable.<\/p>\n

\u0418\u0442\u043e\u0433<\/h2>\n

Technical specifications are promises, and promises are only as good as the factory making them. Suizhou Xuhui Stone controls the full chain from its own G682 quarry through block selection, slab production and surface finishing, so the figures above are not averages collected from the market — they are what we ship every day. Request a sample kit and test reports to verify them on your own bench.<\/p>","protected":false},"excerpt":{"rendered":"
