A frame scaffold parts list should describe a complete working arrangement, not a price for main frames alone. At minimum, identify the frame model, cross braces, joint pins, lock pins, bases, platforms, guardrails, access and ties or stability parts required by the design. Give quantities by bay and lift, dimensions in mm, surface finish and destination. A supplier can then price the same scope that the scaffold designer has planned. Without this detail, two quotations may differ because one includes decks and bases while the other includes only frames and braces. This guide gives nine RFQ lines and a practical method for translating a scaffold elevation into a bill of materials. It also shows where to request compatibility evidence for replacement stock and how to ask for packing information without inventing a universal 40HQ piece count.

List nine groups separately: main frames, cross braces, joint pins, lock pins, bases, working platforms, guardrails and toe boards, access equipment, and ties or other designed stability parts. Give each group a drawing reference, size, quantity and finish. State the number of bays and lifts so the supplier can check whether the schedule is complete.
RFQ line | Information to state | Frequent omission |
|---|---|---|
Main frame | Type, width, height, tube and lock style | Clear opening or bearer level |
Cross brace | Pin-centre length and end detail | Matching brace-pin pattern |
Joint pin | Diameter and retention | Vertical stacking parts |
Lock pin | Type and quantity | Pins or clips sold separately |
Base | Jack, plate or approved caster | Ground and bearing detail |
Platform | Plank/deck size and bearing | Hooks or intermediate support |
Edge protection | Guardrail and toe board | Full working-lift coverage |
Access | Ladder, stair or hatch | Access route between levels |
Stability | Ties, braces or outriggers as designed | Special-bay allowance |
The main frame is a welded structural unit, but its purchase line must identify more than outside width. Add height, clear opening where relevant, platform bearer elevation and connection geometry. Cross braces are selected for the actual bay length and brace-pin positions. Joint pins connect stacked frames; lock pins or clips secure designated joints. These items can vary even when the frames have the same nominal width.
OSHA's fabricated-frame scaffold guidance shows the roles of base, platform, bracing, access and fall protection for US projects. Use the selected jurisdiction's rules and manufacturer configuration to finalize the order.
A complete bay typically needs main frames, matched cross braces, joint and lock pins, bases, platforms and the edge protection and access specified by the design. Ties or other stability parts may also be required. Count from the approved scaffold plan; a “two frames and two braces” package is not a complete working scaffold at every height or duty.
Quick answer: Start from the approved scaffold plan and mark every bay, lift and decked level. Assign a part number to each component, then count typical and special bays separately. Include the intended use, safe working load, ground condition, access and tie locations. Ask the supplier to return the bill with assumptions and exclusions visible.
Begin with the site elevation. Record facade length, working height, bay length, frame width, platform width and the number of decked lifts. Mark doorways, corners, loading points and areas where the scaffold cannot be tied in the usual way. An ordinary bay count cannot capture those exceptions. Request a separate detail and materials line for each exception.
For a new system, choose one frame family and quote all mating parts together. For a top-up order, identify the existing fleet's manufacturer or model and send drawings or samples. A new brace that reaches the old pin may still fit incorrectly; a new platform with the right length may have a different hook. The compatibility check needs the exact interfaces, not only colour or country of origin.
Include the finish: painted, powder coated, pre-galvanized or hot dip galvanized as offered for the actual model. The finish affects purchase price and maintenance planning but does not set scaffold capacity. Ask for material grade and tube wall thickness on the drawing. A 48.3 mm O.D. frame tube is one possible reference, but the quoted SKU must state its own tube and weld details.
Make the quantity sheet auditable. Use one row per part and size, with unit, quantity, unit weight, extended weight and bundle ID. A supplier who proposes an alternate platform or base should identify the substitution in writing. Keep drawing revisions tied to the quotation date so a later change in bay length does not silently alter brace and deck quantities.
Verify that every brace, joint pin, lock pin, platform and base is listed for the same frame family. Ask for connection drawings or a trial assembly for replacement orders. Record finish and material separately from structural fit. A shiny coating or matching paint cannot establish that an accessory belongs to the system.
Frame scaffold compatibility has several levels. Geometric fit asks whether parts physically connect. Functional fit asks whether locks engage and platforms bear correctly. Structural suitability asks whether the full bay has the required load and stability for the intended task. A supplier photo may help identify parts, but drawings and design data are needed for the latter checks.
At receiving, count parts by package label and compare with the approved bill. Inspect brace ends, frame legs, welds, joint pins, bases and platform hooks. Keep damaged or unidentified parts out of the erection area. A complete material count does not guarantee good condition; the site inspection remains necessary.
For mobile work, a caster is not a general substitute for a base jack. The manufacturer configuration should state the wheel connection, locks, permitted height and movement conditions. For stationary work, check jack extension and bearing. The OSHA supported-scaffold overview separates these scaffold types and gives a useful starting point for the RFQ discussion.
Do not use a cross brace as a handrail or access ladder unless the selected configuration and local rules explicitly allow the particular arrangement. Ask for dedicated guardrail and access components in the materials schedule. The platform should be listed by the number of decked bays, not assumed to be included in a “frame set.”
Yes, a supplier can prepare a budget estimate from preliminary bay dimensions and intended use if assumptions are stated clearly. A firm project quotation needs the frame type, bay and lift schedule, platform duty, access, ground condition and special areas. The final scaffold design and component schedule should be reviewed before purchase and erection.
Quick answer: Ask for pieces per bundle, bundle dimensions, gross weight and a 40HQ loading estimate for the exact mix of frames, braces and platforms. Confirm MOQ by frame type and finish, and name the Incoterm and destination port. Compare all supplier offers against the same part schedule and delivery boundary.
Frames are large but relatively open structures, and platforms or long braces may determine packing efficiency. A generic number of sets per container can be misleading if “set” has a different definition. Ask the supplier to state exactly which parts form one set and how every line is packed. The proposed loading plan should include total weight and space, not only piece count.
If the order includes non-standard sizes, OEM branding or RAL colors, price those variants separately. MOQ and production planning may differ from standard sizes. For commercial clarity, record currency, quotation validity, payment milestones and whether the price is FOB Tianjin or another named term. HS code 730840 may be relevant to scaffold equipment, but the customs broker should confirm classification for the actual goods and market.
Our team brings 17+ years of scaffolding manufacturing & exporting experience. One-stop supply from complete systems to single components can help build a complete project schedule. In-house engineering support and project-based technical drawings can be requested with the RFQ when a site layout needs review.

No. A joint pin aligns stacked frame legs, while a lock pin or clip secures the relevant connection in the selected system. Their size and retention detail vary by manufacturer. List both parts separately, send photos or drawings of existing stock, and check a trial assembly before ordering replacement quantities.
Ask for a loading estimate tied to the exact order mix, with pieces per bundle, dimensions, gross weights and total container count. Frame height, platform length and whether bases or guardrails are included can change the plan. Do not compare two “sets per 40HQ” claims until both suppliers define the same set.
