Steel Structure Supplier RFQ Guide: What Buyers Should Send Before Requesting a Quote

A request for quotation sent to a steel structure supplier should contain more than building length, width and total steel quantity. For project-based steel structures, the quotation depends on what needs to be fabricated, which components are included, what drawings are available, how the structure will be delivered and which responsibilities belong to the supplier.

When these details are missing, suppliers may interpret the same inquiry differently. One quotation may include secondary steel and supporting components while another may cover only the main frame. The resulting prices cannot be compared accurately.

A better RFQ gives every potential supplier the same project information and asks them to identify any assumptions or exclusions.

What Drawings Should Be Included in a Steel Structure RFQ?

Send the latest available project drawings.

Depending on the stage of the project, these may include general arrangement drawings, structural drawings, component information or fabrication-related details.

The purpose is to give the steel structure supplier enough information to understand the project configuration.

Buyers should identify:

– Drawing revision
– Building or structure dimensions
– Main structural layout
– Connection requirements where available
– Component locations
– Openings and interfaces
– Secondary structure requirements
– Any details still awaiting confirmation

If some drawings are preliminary, state this clearly.

A preliminary quotation can still be useful, but it should not be confused with a final fabrication quotation based on approved documents.

Define What the Supplier Must Supply

A steel structure supplier may provide different combinations of products depending on the project.

Before sending an RFQ, prepare a supply list.

Possible items can include:

– Light steel structures
– Heavy steel structures
– Bridge steel structures
– Pipe trusses
– Lattice columns
– Purlins
– Floor decks
– Color steel sheets
– Other supporting steel components required by the project

Only include products actually needed for the project.

Do not assume that secondary components are automatically included because the main steel frame has been quoted.

The supplier should confirm what is included and what remains outside the quotation.

Provide the Required Quantity or Project Scope

For some projects, buyers already have a detailed bill of quantities. For others, quantities may still need to be developed from the drawings.

Whichever situation applies, explain it in the RFQ.

Useful quantity information includes:

– Number of buildings or structures
– Required component quantities where known
– Project phases
– Expected shipment batches
– Areas or zones included in the quotation

If the quantity remains preliminary, mark it accordingly.

This helps avoid a situation where an early budget quantity is later treated as a final order quantity.

State Material and Project Requirements Clearly

If the project design specifies particular materials, those requirements should accompany the inquiry.

Do not ask the supplier to select a material solely from a project photograph or basic building dimensions.

The RFQ should identify technical requirements already established by the project team.

These may include:

– Required steel specifications
– Required structural configuration
– Project design requirements
– Required surface treatment
– Local project conditions
– Connection requirements
– Any documentation required by the project

If the buyer has not yet finalized a requirement, indicate that it requires confirmation.

This is safer than inserting an assumed value.

Include the Project Location

Project location can affect engineering coordination, logistics and delivery planning.

For overseas projects, provide at least the destination country and the expected delivery location available at the RFQ stage.

The supplier may also need to understand whether the site presents particular transportation or unloading constraints.

Project Location Information

– Destination country
– Destination city or project area
– Expected delivery point
– Port information if already determined
– Site access limitations if known
– Storage conditions if relevant

Do not wait until production is complete to raise major transportation restrictions.

Long structural members and project-specific components should be considered together with the delivery plan.

Explain Packaging and Shipment Expectations

Export steel structures normally contain many members and connection components that must later be identified on site.

The RFQ can therefore include any known requirements for packaging, component identification or shipment sequence.

Buyers can ask:

– Should components be grouped by building zone?
– Is phased delivery required?
– Does the erection sequence affect shipment planning?
– Are small components required to be packed separately?
– Are there restrictions on package dimensions?

Not every project needs a complex shipment plan, but discussing these questions early can make later coordination easier.

Separate Fabrication From Installation Responsibilities

A supplier may fabricate and deliver the steel structure while the project contractor performs site erection.

In other cases, installation guidance may also be required.

The RFQ should define what support the buyer expects.

Possible requirements include:

– Fabrication
– Detailed design coordination
– Packaging
– Delivery
– Installation guidance
– Technical communication during project execution

Hebei Tengwei Steel Structure Co., Ltd. provides project-based services covering detailed design, fabrication, packaging, delivery and installation guidance.

The exact scope for a particular order should still be confirmed in the quotation.

How to Make Supplier Quotations Easier to Compare

Send the same RFQ package to every supplier and request a clear list of inclusions, exclusions and assumptions.

Supplier Comparison Checklist

– Same drawing revision
– Same quantity basis
– Same material requirements
– Same component scope
– Same surface requirements
– Same packaging scope
– Same delivery basis
– Same technical support requirement

If one supplier proposes a different configuration, record the difference before comparing price.

Otherwise the commercial comparison may hide a technical difference.

Common RFQ Mistakes

Sending only building dimensions

Overall dimensions do not define the full structure.

Requesting price from an outdated drawing

A quotation based on an old revision may no longer match the project.

Failing to list supporting components

This can create gaps between the expected and quoted scope.

Not identifying preliminary information

Budget data and final production data should not be treated as the same.

Comparing suppliers with different delivery scopes

Fabrication-only and fabrication-plus-delivery quotations are not equivalent.

Leaving installation responsibilities unclear

The buyer should know which tasks belong to the supplier and which belong to the site team.

FAQ

What information should I send to a steel structure supplier?

Send available drawings, project dimensions, required products, quantities, material requirements, surface requirements, project location and expected supply scope.

Can I request a quotation without final fabrication drawings?

A preliminary quotation may be possible from available project information, but final production requirements should be confirmed before fabrication.

Should secondary steel components be listed separately?

Yes. If purlins, floor decks, color steel sheets, lattice columns or other supporting components are required, identify them in the scope.

Why does the destination matter during quotation?

The destination can affect packaging, delivery planning and project coordination.

How should I compare quotations from different steel structure suppliers?

First align the technical and supply scope. Compare price only after confirming that the suppliers are quoting against the same requirements.

Conclusion

A well-prepared RFQ reduces assumptions before they become production problems.

For a steel structure project, send the latest drawings, project scope, quantities, material requirements, required components, surface treatment requirements, destination and expected service scope.

Hebei Tengwei Steel Structure Co., Ltd. serves overseas contractors, construction companies, subcontractors, distributors and project purchasers with steel structure fabrication and supporting services.

Providing complete project information at the inquiry stage allows the supplier to review the actual requirement and prepare a quotation based on a clearer scope.
