Brown Angola Marron Antique Granite Slabs for Floor and Wall
Grade : Standard Grade
Brown Angola Marron Antique Granite Slabs are natural brown granite slabs selected from Angola brown granite quarry resources. The surface shows antique marron brown, dark coffee and black mineral base with bronze-grey crystalline depth and dark antique-brown mineral clouds mixed with black crystals and warm bronze speckles. With density around 2.68 - 2.90 g/cm3, water absorption < 0.28% and compressive strength 170 - 250 MPa, the material is suitable for floor slabs, wall panels, exterior.

Product description
Brown Angola Marron Antique Granite Slabs are natural granite slabs designed for projects requiring warm color, durable stone performance and practical long-term decorative value. The selected material is associated with Angola brown granite quarry resources; selected blocks show antique brown tone, dense structure and durable tile performance. It presents antique marron brown, dark coffee and black mineral base with bronze-grey crystalline depth, giving the finished tile a recognizable brown granite character for both residential and commercial specifications.
The stone body has dense African brown granite texture with compact interlocking grains and low-porosity crystalline structure. Its visual layout is defined by dark antique-brown mineral clouds mixed with black crystals and warm bronze speckles. This helps designers create broad floor and wall surfaces with a natural warm tone while maintaining controlled visual continuity across the installation.
Granite is formed through slow crystallization and geological compression, so Brown Angola Marron Antique Granite Slabs provide reliable hardness, compression resistance and dimensional stability. They are recommended for floor slabs, wall panels, exterior covered cladding, stair covers and luxury commercial interiors. Sealing is advised for wet zones, food areas and exterior environments to improve stain resistance and simplify maintenance.
Category: Natural Granite Slabs
Color: antique marron brown, dark coffee and black mineral base with bronze-grey crystalline depth; each batch should be checked by dry layout before installation because natural brown granite may show mineral and tone differences.
Surface Finish Available: Honed / Polished / Brushed / Tumbled / Sandblasted / Bush-hammered / Flamed / Leathered
Product Form: Natural Granite Slabs
Texture: dense African brown granite texture with compact interlocking grains and low-porosity crystalline structure. polished finish gives dramatic antique depth; flamed and brushed finishes suit heavier floor use.
Density: 2.68 - 2.90 g/cm3 (stable compactness for long-term tile service)
Water Absorption: < 0.28% (sealing treatment recommended according to finish and installation area)
Compressive Strength: 170 - 250 MPa (suitable for normal architectural tile applications)
Abrasion Resistance: excellent durability for busy floor areas and long-term wall cladding
GANGSAW SUITABILITY
Brown Angola Marron Antique Granite Slabs raw blocks are compatible with standard gangsaw processing equipment for slab and tile cutting. The stone features stable internal crystalline structure and practical finished-product yield. Dark antique-brown mineral clouds mixed with black crystals and warm bronze speckles help the finished slabs retain a recognizable natural appearance after calibration, edge trimming and surface finishing.
Recommended Processing: Gangsaw slabs (1.8 cm & 2 cm), followed by calibration, edge trimming and honed / polished / brushed / tumbled / flamed surface treatment
Expected Slab Yield: Approximately 76-86 slabs per block (based on 1.8 cm thickness)
Polish Result: polished finish gives dramatic antique depth; flamed and brushed finishes suit heavier floor use The final surface should be inspected under project lighting to confirm tone, mineral visibility and batch consistency.
