Granite knowledge
Harobal's 47 granite routes use commercial dimension-stone names. Commercial granite can include decorative crystalline rocks beyond strict geological granite, so identity, source, finish, lot range and test evidence must be approved separately.
Identity control
The commercial category is useful for procurement. Geological classification explains mineralogy, texture, fabric, alteration and use-relevant behaviour. A source-linked petrographic report resolves that distinction where the project needs it.
Appearance programs
These groups organize the selection conversation; they are not grades and do not replace lot approval.
Evidence matrix
ASTM C615/C615M and applicable BIS/project specifications provide selection frameworks. Acceptance criteria must come from the licensed current standard and project specification; the catalogue does not reproduce or invent thresholds.
Commercial identity
commercial-identityApproved trade name plus aliases; never rely on colour words alone.
Geological identity
petrographic-descriptionPetrographic classification, mineralogy, texture, fabric, alteration and unstable constituents when use warrants it.
Source & lot
origin-claimCountry/state/district/quarry precision supported by current supplier and lot chain; IBM association alone is reference geography.
Approved visual range
colour-rangeCurrent slab/bundle/block range, finish, lighting, date and approval reference.
Movement & variation
movement-variationGrain, banding, veining, inclusions, fissures, repairs and directionality for the approved lot.
Processing disclosure
resin-fillResin, fill, dye, enhancer, mesh, repair, sealer and surface treatment declaration.
Size & thickness
nominal-thicknessNominal and measured dimensions, tolerances, calibration, edge profile and cutting direction.
Absorption
water-absorptionLot-linked report with method and specimen condition; ASTM C97 or applicable agreed method.
Density / specific gravity
bulk-densityLot-linked result under the named method; do not interchange density and specific gravity.
Compressive strength
compressive-strengthASTM C170/IS 1121 or agreed method, specimen state and source/lot identified.
Flexural strength
flexural-strengthASTM C880 or agreed method with wet/dry condition and relevant orientation.
Modulus of rupture
modulus-of-ruptureASTM C99 or agreed method; keep distinct from flexural strength.
Abrasion
abrasion-resistanceMethod-specific result where flooring/paving traffic makes it relevant.
Slip performance
slip-resistanceExact proposed finish tested in the relevant wet/dry condition using the project/destination method.
Finish control
Approve the exact material–finish combination. Family-level availability does not prove a quarry/lot will finish uniformly or meet the intended use.
Application control
Material, finish, dimensions, support/fixing, exposure, loads, maintenance and destination requirements determine suitability.
RFQ checklist
Send the same identity, finish, dimensional, testing, inspection and packing requirements to every proposed source.
Project-ready request
Share the application, destination, drawings, quantity and approval requirements. Final availability and origin are confirmed per proposal.
