Fit & interface advice
We help match substrate, load class, and finish language to your node — so the RFQ names the right family before samples.

Match load & scenario — then send the RFQ
Dashitou (大石头 / Big Stone Fastener) works with overseas project buyers, fabricators, and importers on stone cladding, structural steel, and heavy-duty site fixings. Start from the job condition, not a retail shelf.

Brand stance
Built around site load — not shelf SKUs
Big Stone starts from cladding wind load, concrete edge distance, and steel connection torque. We partner with importers, fabricators, and project buyers who need clear specs for stone and heavy-duty programs.
How we work with buyers
Fit advice · Lead-time talks · Drawing-led OEM
Buyer-benefit commitments for overseas RFQs. Capability detail is confirmed in conversation — we do not invent ISO numbers, rankings, or client lists here.
Schedule
Lead-time negotiation
Replies include realistic production windows, export packing options, and what changes qty or finish will move the date.
OEM
Drawing-led collaboration
Private label, drawing-based variants, and sample loops for stone, structural, and heavy programs — print first, then pack.
Technical support
Load & node → Review route → Agree checks
Stone / structural / heavy RFQ path. Honest capabilities only — no certificate wall, no invented ISO/CE numbers. Docs shared privately when relevant to the order.
-
01 / LOAD & NODE
Name the substrate, load path, and controlling drawing or revision for the install node.
-
02 / REVIEW ROUTE
We confirm manufacturability, finish, and qty band against that node before quoting.
-
03 / AGREE CHECKS
Sample loop, packing / ID note, and reply window — then treat the RFQ as complete.
Evidence we can work from
Drawing review
Send prints or sketches; we flag missing callouts and confirm the part can be made to the node.
Sample loop
Trial pieces against the agreed print — dimensional and finish checks stated in the reply.
Packing / ID note
Export packing and lot ID options noted with the quote path — not a public cert wall.
No invented certificates on public pages. Applicable docs shared privately when relevant → Contact / RFQ.
Buyer prep
Before you open the RFQ
Short desk steps for stone, structural, and heavy enquiries — same job as buying guides, without a second product mega-nav.
01
Prepare an RFQ
Company, country, load / scenario, qty band, and target use or standard. Start from the install node, not a shelf SKU.
Open RFQ checklist →02
Drawing handoff
Attach dimensioned drawing, CAD, or a clear sketch by email after the form. Mark revision and controlling node.
Drawing handoff guide →03
What we reply with
Family fit, finish options, sample / packing note, and next questions — datasheets follow enquiry, not a public PDF wall.
