Visual range
Define acceptable color, veining, fossils, pores, resin, mesh, filling, repairs and bookmatch expectations using representative controls.

Technical Specification Guide for Natural Stone
Good natural-stone specifications separate visual approval from performance requirements. This page is a buyer checklist—not a substitute for project engineer, architect, installer or laboratory advice.
Dimensions
State nominal size, thickness, squareness, flatness and project tolerances. Do not assume every product type uses the same tolerance.
Performance tests
Request current, material-specific test data where relevant: absorption, density, flexural strength, abrasion, frost resistance, slip or anchor performance.
Exterior exposure
Consider climate, freeze-thaw, salts, pollution, moisture, thermal movement, anchoring system and façade engineering.
Wet areas
Coordinate finish, slip resistance, waterproofing, substrate, slope, grout/movement joints, sealing and cleaning chemistry.
Packaging & handling
Define crates or bundles, protective layers, labeling, moisture protection where needed, loading sequence and site storage.
RFQ checklist
Minimum useful specification
Stone trade names are not technical standards. Final selection should be tied to the actual material source, approved reference range and project-specific test reports.
- Stone name / reference sample / desired color family
- Application and interior/exterior exposure
- Formats, thicknesses, quantities and drawings
- Face finish and edge details
- Selection grade or acceptable visual range
- Required test standards or certificates
- Packaging, labeling and delivery sequence
- Destination and requested commercial term
Frequently asked
Questions buyers often ask
What information should I include in a technical inquiry?
Send the stone name or preferred color, required format and thickness, approximate quantity, finish, destination and timing. Drawings, schedules and reference samples are especially useful for cut-to-size projects.
Does Atlas own a quarry?
Atlas Global Trading Inc. operates as an independent sourcing and trading company. We coordinate supply with established quarry owners and processing factories in Turkey rather than limiting projects to a single quarry.
Can Atlas combine multiple Turkish stones in one project?
Yes. Multi-material schedules can be coordinated across compatible partner factories, with attention to samples, production timing, packing and shipment planning.
Can buyers request current slab or block photos?
Yes, subject to supplier availability. For natural stone, current-lot photos and representative samples are an important part of confirming color, vein movement and acceptable range before production.
