Steel props for sale should be compared by their usable working height and model-specific load chart before unit price. Two props that look alike may have different tube diameters, wall thicknesses, pin assemblies and capacities at the same extension. A useful supplier request therefore states the support application, required height range, design load at each position, top connection, quantity, finish and delivery terms. Ask for a drawing and load data for the exact proposed model, then have the temporary-works designer check the selection. A low unit price cannot resolve a missing load chart or an incompatible U-head. This guide turns an open-ended buying inquiry into an eight-part RFQ that distributors and contractors can use to obtain comparable quotations, suitable packing information and a realistic shipping plan.
On this page
State the minimum and maximum working height, required load at each installed height, inner and outer tube diameter, wall thickness, pin type and top connection. Request the supplier's dimensioned drawing and load chart for the named model. The engineer should verify the erected support arrangement, bearing and bracing separately from the purchase specification.
An adjustable prop uses an inner tube sliding within an outer tube. A pin sets the coarse height, while a threaded sleeve and nut provide fine adjustment. The top plate or U-head transfers load from formwork beams; the base plate bears on the support surface. Each component affects interchangeability, handling and how the assembly can be installed.
Do not describe a prop only as “heavy duty” or “3 m.” The first label has no consistent capacity, and the second may mean a maximum extension rather than a useful working range. Record the actual distance between the supporting surface and the underside of the beam or head. Allow for the head geometry, beam depth, sole plate and adjustment travel.
RFQ field | Information to send | Why it matters |
|---|---|---|
Working height | Minimum and maximum installed height in mm | Prevents selection near or beyond travel limits |
Design load | Required load per support point in kN, with layout | Allows comparison with the model's load chart |
Tubes | Inner/outer O.D. and wall thickness in mm | Identifies the specific proposed construction |
Pin | Diameter, shape and retaining detail | Avoids incompatible replacement pins |
Top and base | Plate dimensions or U-head opening | Matches beams and bearing arrangement |
Finish | Painted, powder coated or hot dip galvanized | Changes maintenance and commercial cost |
Quantity | Pieces by height and head type | Makes pricing and packing comparable |
Delivery | Destination port, Incoterm and target date | Defines freight quotation scope |
Historical product notes list some outer tubes around 56–60 mm O.D. and inner tubes around 40–48 mm O.D., with wall thicknesses around 1.8–2.4 mm. These are examples of possible configurations, not a catalogue promise. The supplier drawing and actual batch specification should control the purchase. A tube diameter by itself does not establish safe working load.
Bulk price depends on the prop model, working height, tube size, finish, quantity and packing. A 3 m maximum-height label alone is not enough to compare offers. Send the same eight-field RFQ to each supplier and ask for an itemized price under the same Incoterm, with pins and head parts clearly included or excluded.
Quick answer: Ask each supplier for the same model drawing, installed-height load chart, material and finish description, unit weight, packing method and inspection process. Include the proposed use and project loads. Compare the submitted evidence line by line; a quote that omits critical details is incomplete even if its price appears attractive.
The first technical question is whether the quoted model covers the full height range at the design load. A prop's allowable load can change as its inner tube extends. Request the chart in a form that identifies the specific model, height and stated conditions. The temporary-works engineer then checks prop spacing, eccentricity, lateral restraint, bearing and construction sequence against the design. Do not use a generic “tons per prop” label as a design value.
The second question is whether the head and base details match the beam arrangement. A flat top plate can be suitable where the planned detail provides proper bearing. A U-head captures a timber or H20 beam differently, but its clear width and seating still need checking. Include a sketch or photo of the intended connection rather than asking the supplier to guess.
The third question is parts control. Confirm whether the prop pin is retained, whether the nut and threaded sleeve are supplied as an assembly, and how replacement parts are identified. Mixed pins or improvised parts are a frequent source of avoidable uncertainty in rental fleets and large projects. Specify how each prop size will be marked on receipt.
The fourth question concerns finish and service environment. Paint may suit short projects with planned maintenance; hot dip galvanized components can reduce exposed-steel maintenance in harsher storage conditions. The correct finish depends on exposure, handling and budget. Ask for the finished-product description and inspection criteria rather than assuming a finish determines structural condition.
For US projects, the OSHA cast-in-place concrete requirements address shoring plans, inspection and support. The HSE temporary works guidance is a useful reference for planning and management. Neither source replaces the project design or the quoted model's data.
Compare total landed scope, not only the unit price. Confirm quantity by size, unit weight, bundled quantity, gross weight, package dimensions, container plan, Incoterm and destination. Ask whether pins, nuts, U-heads and replacement parts are included. A clear packing list prevents a low headline price from hiding missing components or inefficient freight.
For bulk purchasing, a 40HQ container loading quantity is meaningful only for a named prop size, unit weight and packing pattern. Longer props and mixed-height orders can change the load plan. Ask for a proposed container loading sheet showing pieces per bundle, bundle dimensions, gross weight and the assumed container. Treat that sheet as a planning estimate until the order mix is fixed.
MOQs may vary with the size, finish and customization. Instead of asking for one universal MOQ, request the minimum order quantity for each line item and for a mixed-size order. If you need non-standard sizes, OEM branding or RAL colors, state those requirements up front so the supplier can show the impact on tooling, packing and lead time. One-stop supply from complete systems to single components may help when props, U-heads and related formwork parts travel together.
Ask whether the price is FOB Tianjin or another named term, and record the quotation currency, validity period and included documents. Freight, destination charges and duties are separate commercial questions. HS code 730840 is commonly considered for scaffolding, shuttering or propping equipment, but the final tariff classification should be confirmed with your customs broker for the actual goods and destination.
Our team brings 17+ years of scaffolding manufacturing & exporting experience. The export workflow includes in-house engineering support and project-based technical drawings, which can help buyers compare the specified prop configuration with the intended formwork layout. Request a written drawing revision and line-item quotation so any later change is visible.
Yes, many bulk steel-prop orders can be planned for a 40HQ container, but the piece count depends on prop length, unit weight, bundle size and order mix. Ask the supplier for a packing drawing and proposed loading plan for your exact schedule. Container suitability also depends on weight distribution and destination handling limits.
Quick answer: Send one schedule that lists each prop height, required design load, head type, finish and quantity. Attach the support layout, beam detail and destination terms. Ask the supplier to return a model-specific drawing, load chart, packing plan and itemized price. Have the project engineer review the technical return before purchase.
Use this short format to start an inquiry:
Application: slab formwork, beam support or another defined use; include the country and project stage.
Height schedule: list clear support heights in mm for each zone, not one approximate building height.
Load schedule: state required load per support point and attach the design layout or engineer's assumptions.
Connections: name the top plate or U-head and show beam dimensions and base bearing details.
Model preferences: state tube size, wall thickness, pin assembly and finish if already specified.
Order split: show quantity by size and any spare-pin or spare-nut requirement.
Packing: request bundle, gross weight and 40HQ loading estimate for the proposed mix.
Commercial terms: specify destination port, FOB Tianjin or alternative term, and requested shipping window.
If a design is still developing, say which fields are provisional. The supplier can then quote alternatives with the assumptions shown instead of substituting an unmarked size. When comparing returns, put the load chart and drawing next to the price sheet. Follow up on any mismatch before signing a purchase order.
See our scaffolding and formwork product range and steel prop extension guide. For a line-item quotation, use the project inquiry page.
Choose a prop whose usable height range and model-specific load chart cover the designed support point. Measure the clear support height in mm after accounting for the beam, head and sole plate. The temporary-works designer should check spacing, bracing, bearing and construction sequence before the purchase quantity is finalized.
Request a dimensioned model drawing, the matching load chart, material and finish description, itemized price and packing plan. Each document should identify the proposed prop model and any optional head or pin. If the order uses several sizes, ask for a separate line and drawing reference for each size so substitutions are visible.
Send your height schedule, support layout, required loads, quantities and destination port. We can prepare a project quotation and drawings for review. Email mason@easy--scaffolding.com ｜ WhatsApp +86 13212036031 ｜ https://www.easy-scaffolding.com/
