Product Introduction

G654 Granite Flamed Slab is a dark grey, fine-to-medium-grained quartz diorite extracted from established quarry reserves in Fujian Province, China. Operating as a direct-processing China stone factory, Xiamen YoYo Stone procures first-tier raw quarry blocks selected for consistent dark charcoal tones, uniform mineral dispersion, and an absence of white quartz lines or iron knots. Our processing plant executes automated high-temperature thermal flaming using calibrated oxygen-propane torch arrays, producing a textured, non-reflective surface that provides high friction ratings while preserving crystalline rock cohesion. We deliver factory-customized architectural elements, spanning full gangsaw slabs, calibrated modular paving tiles, pool coping, and kerbstones cut to engineering shop drawings. With stable block allocations and automated multi-blade bridge cutters, we maintain strict tonal consistency across multi-container shipments for large-scale exterior developments.

Quality Control & Inspection Standards

YoYo Stone applies an industrial five-tier quality inspection protocol to every production run of G654 granite flamed slabs, ensuring complete compliance with ASTM C615 building stone criteria. Our technical controllers monitor block orientation prior to gangsaw sawing to align the natural rift line of the granite, optimizing flexural load capacity. Flaming speeds and oxygen-propane ratios are monitored to guarantee uniform texture depth across entire slab faces without generating micro-fissures or overheating quartz crystals.

Block Grain & Flaw Inspection

Raw quarry blocks undergo ultrasonic density checks and four-side water testing to detect and discard hidden geological fissures, dark spots, and biotite clusters.

Laser-Guided Sawing Verification

Multi-blade bridge saws calibrated with infrared laser beams maintain cutting tolerances within ±1.0 mm, eliminating edge wedging and step marks across modular panels.

Thermal Flaming Texture Uniformity

Slabs are inspected under oblique lighting to confirm even crystal spalling, ensuring uniform surface roughness without scorched dark patches or smooth un-flamed voids.

Pre-Shipment Dry-Lay & Crate Banding

Tiles and slabs are dry-laid on factory floors to confirm color balance, then packed into fumigated hardwood crates with corner buffers and galvanized steel straps.

Products Application

Typical Project & Application Scenarios

01.

Exterior Building Facades & Ventilated Curtain Wall Cladding

With high flexural load capacity and water absorption under 0.20%, G654 Granite Flamed Slab serves as an engineered cladding material for exterior anchor-bolt and curtain wall installations. The uniform thermal flamed texture diffuses harsh sunlight to prevent glare, resisting acid rain, atmospheric pollution, and freeze-thaw degradation across commercial high-rises and municipal facades.

02.

Heavy-Traffic Municipal Paving, Wet Decks & Landscape Steps

Tested to an R11/R12 slip rating (PTV ≥45≥45), flamed G654 panels are specified for high-density pedestrian plazas, transit hubs, and swimming pool terraces. Our China stone factory supplies factory-customized paving tiles, rebated drop-face pool copings, and solid stair treads with anti-slip grooving, withstanding continuous mechanical abrasion and vehicle wheel loads without surface polishing.

FAQ

Everything You Want To Know

G654 grey granite flamed cut to size tiles

01. How do you manage color consistency across different quarry batches of G654 granite?

We assign raw blocks sourced exclusively from identical extraction benches within the G654 deposit for single-contract runs. During dry-lay inspection, our technicians sort slabs into tonal grades under daylight-balanced illumination, excluding blocks that exhibit irregular grain variations or white feldspar streaks.

02. Why is a flamed finish preferred for exterior G654 granite paving and coping?

High-temperature flaming thermally shocks the quartz and feldspar crystals, creating a rough, micro-textured topography. This textured profile produces a wet pendulum slip resistance value exceeding PTV 45 (R11 rating), preventing pedestrian hydroplaning while hiding daily foot traffic abrasion and atmospheric dust buildup.

03. How do you prevent rust spots or dark staining on outdoor G654 flamed slabs?

G654 has low iron sulfide content, minimizing natural oxidation. We recommend impregnating the flamed surface with a breathable penetrating silane/siloxane sealer after installation. This barrier blocks capillary moisture ingress from damp mortar beds while allowing internal stone vapor to escape without forming surface efflorescence.

04. What are the maximum slab dimensions and thickness tolerances for G654 flamed pavers?

Our primary gang saws produce jumbo slabs up to 2800 × 1600 mm in 20 mm, 30 mm, and 50 mm thicknesses. Dimensional tolerances are held within ±1.0 mm for length and width, and ±1.0 mm for calibrated thickness, ensuring flush joint alignments when installing with narrow 3mm architectural grout lines.

05. How are heavy G654 granite slabs packed to prevent transit cracking and container overweight?

Slabs are packed vertically inside ISPM-15 certified fumigated timber A-frames or closed crates, separated by polyethylene sheeting and high-density foam pads. Heavy crates are secured with galvanized steel banding and floor chocks to distribute the 个total payload below 21,500 kg per 20ft container for standard road transit limits.
