Load path & install node primer

Define · why name the three fields first

An RFQ that starts with a shelf SKU forces a confirm-before-quote loop. Name the install condition first: what the part bears into, what load language the site already uses, and the one arrow sentence that rules the detail. Leave strength class, coating, and certificate lines blank when the print does not fix them — blanks are easier to clarify than invented grades.

Use this primer beside the RFQ checklist (field 02) and before you open Enquire / RFQ. If a drawing already exists, keep revision and controlling node with the file via drawing handoff.

Discuss · five job conditions

Each block below is one RFQ routing path: substrate → load in buyer words → one install-node sentence → family hint → common miss items. Final family fit is confirmed in enquiry against your print — this page does not invent grades or certificates.

Stone cladding / panel to backup

Substrate. Natural stone panel or soffit fixing into concrete backup, steel frame, or a rainscreen subframe. State panel material and thickness band when known; say which backup you actually meet.

Load (buyer words). Wind + dead at the panel. Strength class can stay blank on the first email if the print does not lock it.

Install node. Stone panel → backup via undercut anchors, edge brackets, or soffit fixings — pick the detail that rules the part.

RFQ routing. Stone fasteners / cladding brackets — see Applications · stone cladding.

Common miss items. Panel thickness omitted; backup type left as “façade”; undercut vs edge-bracket style not marked; no controlling detail callout on the sheet.

Structural steel bolted joint

Substrate. Structural steel member, gusset plate, bracing node, or connection plate. Name the connection in buyer words rather than a shelf bolt title.

Load (buyer words). Shear, tension, or combined action at the joint. Prefer load language over inventing a grade online.

Install node. Beam / gusset bolted joint — diameter, length, class, and coating follow the controlling revision.

RFQ routing. Structural bolts / heavy hex — Applications · steel structure.

Common miss items. Class or coating guessed without a revision letter; nut / washer set not stated; mixed assortment treated as one SKU; file name missing the revision.

Heavy baseplate on slab

Substrate. Equipment baseplate or plant frame bearing on concrete slab or foundation. Name the equipment or frame when the site engineer already uses that label.

Load (buyer words). High-load bearing plus any plant vibration or dynamic note already written for the job. Do not invent embedment numbers on this page.

Install node. Baseplate → slab (or foundation) via heavy hex / wedge or chemical accessories as the print shows.

RFQ routing. Heavy hex / wedge or chemical accessories — Applications · heavy industrial.

Common miss items. Embedment and diameter left blank with no “per drawing” note; vibration note omitted when the plant already has one; washer / nut set assumed rather than listed.

Facade & rainscreen rail

Substrate. Metal or composite skin on an aluminum or steel subframe. Say subframe material; coastal or industrial atmosphere when it drives finish.

Load (buyer words). Clip pull-out / bracket load on the rail; wind on the skin is enough for a first pass.

Install node. Rainscreen skin → subframe (clip or bracket). Atmosphere and clip type control the node.

RFQ routing. Cladding fixings — Applications · facade & rainscreen.

Common miss items. Subframe type missing; atmosphere not stated when coastal; clip vs bracket style unmarked; finish invented as “equivalent” without a project note.

Concrete anchoring (wedge / chemical)

Substrate. Concrete or masonry for plates, railings, secondary steel, or equipment bases. State cracked / uncracked only if the project note already uses that language.

Load (buyer words). Tension / shear at the embed; edge-distance limits when the engineer has already set them. Edge distance and embedment are buyer-specified.

Install node. Through-fix expansion (wedge) or bonded rod + sleeve (chemical) — mark which path the print rules.

RFQ routing. Wedge anchors / chemical accessories — Applications · concrete anchoring.

Common miss items. Edge distance omitted; sleeve type blank on chemical jobs; diameter / embedment guessed without a controlling detail; finish left as a vague “SS” with no project preference.

Selection notes (not a catalog wall)

Before you lock family language in the RFQ body, check three choke points. If any item is unclear, leave the field blank.

• Edge distance — especially on concrete and stone backup nodes. If the engineer has a minimum, write it; if not, say “per drawing” rather than inventing a number.
• Corrosion / atmosphere zone — coastal, industrial, or interior dry. Finish follows the project note; do not invent coating systems on this page.
• Drawing fields that stall a quote — missing revision letter/number, no controlling-node callout, diameter/length/embedment absent with no “per print” line. Fix these before asking for a firm family match. Handoff steps: drawing handoff.

Scenario → family hint (routing only)

Use the table as a short RFQ map. Detail lives in the five blocks above and on Applications — do not treat this as a materials twin of a stainless warehouse catalog.

Scenario	Typical Dashitou routing
Stone cladding	Stone fasteners / cladding brackets — Applications · stone
Structural steel	Structural bolts / heavy hex — steel structure
Heavy baseplates	Heavy hex / wedge or chemical accessories — heavy industrial
Facade & rainscreen	Cladding fixings — facade
Concrete anchoring	Wedge anchors / chemical accessories — concrete
OEM / private label	Drawing-led kit — OEM programs

Agree · RFQ fields you can copy

Paste into the RFQ “Target use” and “Project notes” boxes, or into the mailto body after the form opens. Then finish the rest of the RFQ checklist (company/country, specs or drawing, qty band).

Home path order stays industrial: RFQ workbench and load-path sit early on the homepage. This primer deepens that language for buyers; it does not add a new homepage module. Related: home load paths, RFQ workbench, Applications, RFQ checklist.
