To source OEM adjustable floor support for concrete slab formwork, define the required support height, design load, adjustment mechanism, material and finish, connection details, and applicable project requirements before requesting a quote. These supports are part of a temporary works system: the selected product must suit the formwork layout and be checked against the project’s engineering requirements. At EVERSTAR, we work with B2B buyers to review these inputs and discuss a feasible OEM configuration before production details are confirmed.

This guide is for formwork distributors, contractors, importers, and construction-equipment buyers comparing suppliers or developing a private-label product. It explains which specifications to request, how to match a support to an application, and what to clarify about price, MOQ, and lead time. Use it as a purchasing framework, not as a substitute for a project-specific structural design.
An adjustable floor support is a height-adjustable component used within a temporary support arrangement for slab formwork. Depending on the system design, it may help transfer loads from the formwork assembly toward the supporting surface while allowing the setup height to be adjusted. The exact function and connection method depend on the product design and the surrounding components.
In a slab-formwork application, the support is not a stand-alone solution. Its suitability depends on factors such as the formwork arrangement, support spacing, slab and construction loads, base conditions, and the way loads are distributed through the complete system. Confirm design responsibility and permitted use with the project’s qualified engineering team.
OEM adjustable supports can differ in their adjustment mechanism, tube or body configuration, base and head interfaces, and surface treatment. Product construction may use steel components, with material grades, dimensions, and coatings selected according to the buyer’s specification and supplier feasibility. Do not assume that two supports with similar appearance have the same capacity or system compatibility.
When discussing an OEM version, identify whether you need a standard product with branding or a changed design. Options to review may include dimensions, end connections, adjustment features, labels, color, packaging, and documentation. Ask the supplier to distinguish confirmed standard features from proposed customizations that require engineering review, tooling, or sample approval.
A clear request for quotation (RFQ) helps suppliers quote comparable products and flags missing design inputs early. Provide drawings or reference samples where available, and state the intended formwork system and market. If a value is not yet confirmed, mark it as “to be confirmed” rather than allowing a supplier to assume it.
| Specification | What to define | What to confirm with the supplier |
|---|---|---|
| Working height | Minimum and maximum operating height in mm | Usable adjustment range and any overlap or extension limits |
| Load requirement | Required design load in kN and the design basis | Rating conditions, test or calculation basis, and applicable limitations |
| Interfaces | Head, base, pin, thread, or connection dimensions in mm | Compatibility with the specified formwork components |
| Materials and finish | Required material, corrosion protection, and appearance | Available options, finish specification, and inspection records |
| OEM requirements | Branding, markings, labels, packaging, and drawing revision | Artwork approval, customization feasibility, and any related charges |
Begin with the slab formwork layout and the load path rather than selecting a support by name alone. Confirm where each support will sit, how it connects to the formwork, and whether the base surface and adjacent components are appropriate for the intended setup. The project design should establish the required capacity and arrangement.
For example, an illustrative RFQ might request a working height of 3,000 mm, a project-defined design load of 20 kN, and an initial order quantity of 500 units. These figures are sample purchasing inputs only; they are not a recommended design, a standard EVERSTAR specification, or evidence that a particular product is suitable. Have the project engineer validate load and configuration requirements before treating any example values as an order specification.
Also consider handling and site conditions. Buyers may need to assess product weight in kg, transport packaging, storage, exposure to moisture, and the expected inspection or maintenance process. If the product must fit an existing system, supply interface drawings and request written confirmation of dimensional compatibility.
EVERSTAR supply professional and honest service.
Ask the supplier to provide a dimensioned drawing and a clear description of the adjustment mechanism and interfaces. For any stated capacity, request the rating basis, test or calculation information available, and conditions or exclusions that apply. A number without context is difficult to compare and should not be treated as proof of suitability.
Request a line-by-line list of what is standard and what is customized. Confirm which changes affect tooling, production setup, inspection, packaging, or approval samples. Agree on the final drawing revision and marking details before placing a production order.
Price comparisons are meaningful only when the quoted specification, quantity, packaging, and delivery terms are aligned. Ask each supplier to state MOQ, sample or tooling charges, production lead time, payment terms, and the point at which the lead-time clock begins. If a supplier cannot confirm a detail yet, request a written estimate and the condition required for final confirmation.
MOQ and lead time can vary with customization, material availability, order quantity, and production scheduling. We recommend buyers request separate pricing for the initial order and likely repeat orders, while confirming whether OEM artwork or tooling is reusable. Avoid selecting solely on the lowest unit price if the specification, inspection scope, or delivery assumptions differ.
Before committing to volume, align on a sample or pre-production approval process where appropriate. Define what will be checked, such as critical dimensions, interface fit, markings, finish, and packaging. The inspection plan should reflect the product specification and buyer’s quality requirements; do not assume a supplier’s standard inspection automatically covers every project-critical feature.
A frequent mistake is sending only a product photo or a requested height without providing load and interface requirements. Another is comparing load figures that were established under different conditions or using different rating definitions. Buyers should also avoid leaving important details—such as adjustment limits, finish, or OEM labels—to verbal agreement.
For custom orders, changing a drawing after sample approval can affect cost and schedule. Keep a controlled record of the approved drawing, specification, sample comments, and purchase-order revision. If a project requirement changes, ask the supplier to confirm the impact before proceeding with production.
At EVERSTAR, we can discuss OEM adjustable floor support requirements with formwork buyers and review the information needed to assess a proposed configuration. To begin, send your target dimensions, project-defined load requirements, interface drawings, material or finish preferences, estimated quantity, destination market, and branding or packaging needs. We can then clarify which details require technical confirmation and prepare a quotation based on the agreed scope.
For a useful first inquiry, attach the latest drawing revision and list any open items separately. If you do not yet have a finalized specification, tell us what is confirmed and what remains under engineering review. This helps keep the initial discussion focused without treating preliminary values as approved design inputs.
The right OEM adjustable floor support for concrete slab formwork is the one that matches the project’s verified load requirements, working height, interfaces, and procurement needs—not simply the closest-looking or lowest-priced option. Define those requirements in an RFQ, request evidence and limitations for stated ratings, and compare commercial terms against the same specification. Your next step is to prepare the drawing, quantity estimate, and OEM requirements, then ask shortlisted suppliers, including EVERSTAR, to confirm feasibility and quote the defined scope.
