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.

About Dashitou Talk RFQ

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.

Interface

Fit & interface advice

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

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.

  1. 01 / LOAD & NODE

    Name the substrate, load path, and controlling drawing or revision for the install node.

  2. 02 / REVIEW ROUTE

    We confirm manufacturability, finish, and qty band against that node before quoting.

  3. 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.

FAQ

Quick answers for buyers

Do you publish prices or MOQ on the site?

No fixed retail prices and no cart MOQ table. Quotes depend on material, finish, quantity band, and Incoterms for stone cladding, structural, and heavy nodes. Share specs on the RFQ form; use Guides · RFQ checklist before you write.

Can you OEM to our drawings?

Yes—send drawings or samples. We confirm manufacturability and packaging against the controlling revision before sampling. Mark revision, units, and controlling node; see Drawing & CAD handoff.

Are certifications listed on every page?

We do not invent certificates, plant area, or ranking badges online. Applicable documents are shared privately when relevant to the RFQ.

Undercut stone vs chemical anchor—which desk?

Dry undercut into stone panels is a different desk from chemical/bonded rod + buyer-side resin. Use Undercut stone anchor RFQ (G4) or Chemical anchor accessories (G6)—one desk per quote thread. If the print is unclear, mark Open and attach the section.

Must structural bolt class match the drawing revision?

Yes. Strength class and coating follow the controlling revision on the connection schedule—not a commercial hex shelf default. See Structural bolt class & coating (G8) and Drawing handoff.

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.

03

What we reply with

Family fit, finish options, sample / packing note, and next questions — datasheets follow enquiry, not a public PDF wall.
