FROM SELECTION TO DELIVERY
Stone Production, Quality Control & Export Packing
Cotrustone acts as an extension of your sourcing and project team in China—connecting material selection, fabrication, inspection and delivery coordination.
Share your brief and attach reference images or drawings securely in the enquiry form.

01 / SELECT
From stone options to selected slabs.
Start with a reference, colour direction and intended use. Compare suitable stones, then review the full slabs for background tone, vein movement and the quantity your project needs.
Before cutting, agree which slabs and areas belong to the visible pieces. Review dimensions, pattern direction and finish together, using current photographs and a physical sample where needed.
Compare Stone OptionsCompare colour and movement.

Confirm the area for each piece.

Separate archive examples: each order’s selection is confirmed against current photographs and the required piece dimensions.
02 / SPECIFY
Engineering & drawings.
Our drafting support brings dimensions, visible faces, junctions, edge details and finishes into reviewable stone drawings. We help develop the fabrication details with your project team and identify interfaces that require the designer, contractor or installer's input.
Link drawing revisions to the item codes and quantities in the stone schedule. Identify the approval owner, site measurements still required and any first-piece or sample-room review. Record changes before they become production assumptions.

03 / QUOTE
Define a comparable scope.
Share drawings or references, quantities, destination and quotation deadline. Identify what is provisional and which items require alternatives so the proposal responds to the actual scope.

PRODUCTION RECORD
Factory & Production
Follow the work behind the finished stone: slab cutting, profile checks, carved details, trial fitting and split-face processing. Different products pass through different operations; the drawings and approved selection connect them.


WORKSHOP OPERATION
Check the profile by hand
Check profiles, recesses and transitions before final finishing.

WORKSHOP OPERATION
From tool path to carved detail
Review relief depth and edge definition before approval.

WORKSHOP OPERATION
Check how the parts meet
Confirm connections, support and handling before packing.

WORKSHOP OPERATION
Develop a natural split face
Set face depth, size range and edge character against the installation.
REVIEW THE WHOLE ARRANGEMENT
Dry lay & vein matching.
A small sample cannot show how a floor, wall or counter will read as a whole. Agree the vein direction and which surfaces need to work together before cutting.
Where dry lay is included, review the arranged pieces against the approved drawing. Check the sequence, joints and transitions, and record any adjustments before packing.

CHECK THE INDIVIDUAL PIECE
Quality inspection.
Check the finished piece against the approved drawing and agreed tolerances. Dimensions, openings, exposed edges and finish need to be reviewed together—not just the overall appearance.
Agree the inspection records for your order. Link measurement photographs and any required corrections to the piece code, so the project team can review the right item before release.
What to include in the inspection record
- Selection record: identified slab or block photographs, linked to the proposed pieces and finish reference
- Drawing review: annotated or dimensioned sheets showing revision, item codes, openings, visible faces and agreed tolerances
- Dimensional record: measurement photographs linked to the piece and the drawing dimension being checked
- Surface review: close-up photographs of agreed edges, corners, bowl openings and joints, with any correction noted
- Layout record: numbered dry-lay photographs linked to the drawing for the multi-piece areas included in the scope
- Dispatch record: packing photographs and a packing list connecting crate IDs, piece codes, quantities, package dimensions and gross weights

05 / DELIVER
Packing & delivery coordination.
Packing
Agree protection, support and identification around the confirmed piece and the destination’s unloading conditions.

Delivery
Coordinate production readiness, shipment and responsibilities around the agreed scope and destination.

Packing and delivery details
Agree a crate and piece-identification system that relates to the packing list and project areas. Review lining and support, package dimensions, gross weight and unloading arrangements before dispatch. For staged projects, define the shipment groups and spare pieces. Agree which records the destination team needs and their format, such as a packing-list spreadsheet or PDF with the corresponding crate photographs. Keep the list and photographs together by crate ID so the team can locate an item without relying on the appearance of the outer packaging. Coordinate production readiness, packing and shipment requirements with the agreed scope and destination. Keep responsibilities visible so that the project team can plan the next step. Discuss EXW, FCA, FOB, CIF, DAP or DDP around your destination and supply scope. Confirm the available delivery term, named place and responsibilities in the quotation. Use the packing list to connect each package with its contents and delivery stage. Agree which loading views, crate identifiers and shipping records should be shared. The photograph below records crated stone and timber bracing inside a container; the loading arrangement for a new shipment must be planned around its actual cargo.
