G654 Granite: Identity, Finish Options and Batch Verification

Commercial & trade names

Treat G654, Padang Dark and any “New G654” description as seller-declared names until the offered material is tied to records. Retain the complete label rather than dropping a suffix or replacing it with a familiar name. Record whether the seller claims equivalence, a visual alternative or a new source; those are different statements.

Commercial granite grouping does not settle petrographic identity. If exact rock type or origin is important to the specification, ask for appropriate identification evidence rather than relying on a product label.

Colours & expected variation

Approve the dark-grey appearance from representative pieces in the intended finish. Record the range in ground tone, grain scale, concentrated dark minerals and conspicuous light areas. Different finishes and moisture conditions may change the apparent depth of colour. Compare like with like: dry production pieces against a dry reference, then any agreed wet view separately.

A single photograph cannot establish a universal G654 colour or a permissible variation limit. Mark piece IDs on the approval record so an overall image and a close-up can be connected later.

Quarry & region context

Quarry and lot identity: Not established for an offered order here. Ask for the declared quarry location, block references, processing factory and available documents. Record any substitution from an earlier sample as a new approval event.

This record makes no factual claim that a particular G654 quarry has closed. A seller’s statement about supply history is not a verified quarry-status record. Do not treat processing or export through China as proof of Chinese quarry origin; consult China & Origins for the background questions.

Available finishes

A direct SRS product listing offers polished, flamed and honed versions of its G654 product. That establishes what that seller advertises, not uniform availability or behaviour across all stones bearing the name.

Use the Finishes group to prepare a finish comparison, then approve a production sample for sheen, texture, edge condition and cleaning expectations. Specify slip assessment where relevant; a finish label alone is not a test result.

Available formats

Request drawings for the actual form: slabs, tiles, paving, steps, kerbs or fabricated pieces. Confirm which faces and edges are visible, permitted repairs and reinforcement, and how the packing will keep those surfaces apart.

Follow the slab guide for slab purchases and sizes and tolerances for dimensional questions. Do not use another supplier’s nominal sizes as an agreed tolerance or minimum thickness.

Typical applications

For driveways, patios and stairs, review loading, support, wet use, drainage and edge details alongside the proposed finish. For facades, the design and anchorage require project-specific assessment.

Dark appearance does not establish strength, frost performance or resistance to staining. Keep exposure, geometry and maintenance requirements in the purchase specification and ask for evidence relevant to them.

Technical data to request

Inspection points

Start with the approved range, the purchase specification and the packing list together. Check identifiers before comparing colour: a plausible appearance does not establish that the inspected material belongs to the approved lot.

• Compare faces and visible edges in the agreed finish, lighting and moisture condition. Record concentrated minerals, fissures, fills, mesh or resin treatments separately from handling damage.
• Measure dimensions, thickness, squareness and critical fabrication details against the drawing; use the agreed sampling plan rather than an invented universal tolerance.
• Photograph crate exteriors and labels before unpacking, then photograph piece IDs, overall condition and edge damage with a scale. Keep original files and link every close-up to an identifiable piece.
• Separate observations from acceptance decisions. Record what is outside the agreed range, who can decide its disposition and which pieces remain on hold.

Use the Inspection & receiving guides, edge-chip acceptance guide and receiving inspection and claim record guidance. The edge-chip decision file helps keep damage evidence and the purchaser’s decision together. None of these references certifies an unexamined shipment.

Alternatives to G654: approve a replacement as a new material

SRS markets “G654 New” as an alternative to its original-labelled product. Fortune East markets Cambodian New Padang Dark G654 as another alternative. These are seller descriptions, not independently established equivalence. The second listing declares Cambodian origin; do not relabel it as Chinese-quarried stone because it is offered through a China-based seller.

Do not print a numerical advantage where comparable test results are absent. If an offered alternative cannot meet a critical requirement, change the selection or obtain suitable evidence; changing the name in the purchase order does not resolve that gap.

Related sourcing guides

Work through Samples & approval before agreeing the production run. Retain the approved pieces and record the viewing conditions in the sample and mockup instructions.

Then record the sizes and tolerances, packing and loading arrangements and inspection scope in the order. Crate marks, layout references and spare pieces should connect the production documents to the receiving inspection.

Compare quotations against the same selection range, finish, fabrication, packing and terms. This page provides no live price, supplier endorsement, completed inspection or laboratory result. The cited public standard scopes explain the kind of evidence to request; their full paid clauses have not been reviewed for this record.
