Sandwich Panel Cost Guide: Specifications, Supply Scope and Quotation
Quick Answer
There is no single sandwich panel price because the quotation depends on confirmed specifications, core material, panel thickness, facing steel, quantity, accessories, packing, delivery boundary and installation scope. Two suppliers may both say they are quoting "sandwich panels" while including very different items. The only way to compare quotations fairly is to align the specification and supply scope first, then compare the commercial terms.
Why Two Sandwich Panel Quotations Can Differ
Two sandwich panel quotations can look very different even when both suppliers appear to be quoting the same product. The difference usually comes from four areas:
- Specification — core material, thickness, facing steel, coating, profile and joint system
- Supply scope — whether the quote includes panels only, panels plus accessories, or a full building envelope package
- Commercial boundary — packing, trade term, freight, documentation and installation responsibility
- Production factors — quantity, panel length, production batch and container utilisation
A lower total does not automatically mean a better price. It may simply mean fewer items are included. A higher total may include accessories, packing or freight that the lower quote excludes. Buyers should compare the actual scope behind each number before comparing the totals.
What Determines Sandwich Panel Cost?
Sandwich panel cost is determined by the confirmed project requirements. The main cost drivers include:
- Core material
- Panel thickness
- Facing steel specification
- Coating and finish
- Wall or roof profile
- Joint system
- Panel length
- Effective coverage
- Total quantity
- Production batch
- Accessories
- Trims and flashings
- Fasteners
- Sealants where included
- Openings and special fabrication
- Packaging
- Container utilisation
- Destination
- Trade term (EXW / FOB / CIF)
- Documentation requirements
- Installation scope
Each factor changes the quotation in a different way. The table below explains why each driver matters and what the buyer should confirm.
Table 1: Cost Drivers
| Cost Driver | Why It Changes the Quotation | What the Buyer Should Confirm |
|---|---|---|
| Core material | Different core materials have different production costs and availability | Confirm EPS, PU/PUR, PIR or Rock Wool based on project requirements |
| Panel thickness | Thicker panels use more core material. Facing steel thickness, grade and coating are separate specifications that also affect the quotation | Confirm required thickness for insulation, structural or fire-related needs |
| Facing steel specification | Steel grade, thickness and coating affect material cost | Confirm facing steel requirement and coating system |
| Coating / finish | Different coating systems have different cost levels | Confirm coating type, colour and finish requirement |
| Wall vs roof profile | Roof and wall panels have different profiles and joint designs | Confirm application and required profile |
| Joint system | Joint design affects production complexity and sealing requirements | Confirm joint type and sealing requirements |
| Panel length | Longer panels may affect production, packing and transport | Confirm required panel length based on building dimensions |
| Effective coverage | Coverage affects total panel quantity required | Confirm effective width and total area |
| Total quantity | Larger quantities may improve production efficiency but change batch planning | Confirm total area and required delivery schedule |
| Production batch | Production planning affects scheduling and material ordering | Confirm whether the project is one batch or phased |
| Accessories | Trims, flashings, fasteners and sealants add scope | Confirm which accessories are required and whether they are included |
| Openings and special fabrication | Cut-outs, framing and special details require additional work | Confirm opening locations, sizes and interface details |
| Packaging | Packing method affects material and labour cost | Confirm packing requirements and protection level |
| Container utilisation | Loading efficiency affects freight cost | Confirm loading plan and container type |
| Destination | Distance and logistics affect freight boundary | Confirm destination port or delivery location |
| Trade term | EXW, FOB or CIF changes the cost boundary | Confirm the same trade term when comparing quotes |
| Documentation requirements | Certificates, inspection records or special documents add cost | Confirm required documents before quotation |
| Installation scope | Installation is not included by default | Confirm whether installation is required and how it will be quoted |
How Core Material Changes the Quotation
Core material is one of the main cost drivers. EPS, PU/PUR, PIR and Rock Wool have different production costs, availability and performance characteristics. Each material may also have different documentation requirements depending on the project.
The quotation impact depends on the confirmed specification. A project that requires a specific core material may have a different cost profile than a project that allows a choice. Buyers should confirm the required core material before comparing quotations. For detailed material comparison, refer to the Sandwich Panel Materials Hub and the Material Comparison Guide.
Panel Thickness and Facing Specification
Panel thickness affects the amount of core material used. Thicker panels use more core material, which changes the production cost.
Facing steel specification also affects the quotation. Steel grade, thickness and coating system are separate specifications that also affect the quotation. A project requiring a specific steel grade or coating system will have a different cost profile than a project using standard facing steel.
Buyers should confirm the required thickness and facing specification before requesting a quotation.
Roof Panels vs Wall Panels
Roof panels and wall panels are different products. They may use different profiles, joint designs and load requirements. Roof panels must consider water management, slope and load conditions. Wall panels focus on enclosure, appearance and wind load.
Because they are different products, the cost per square metre may differ. A quotation that mixes roof and wall panels should clearly separate the two so the buyer can compare correctly.
Quantity, Panel Length and Production / Packing
Total quantity affects production planning. Larger quantities may allow more efficient production runs but also require more material and longer production time. Panel length affects cutting, packing and transport. Longer panels may require special handling or different container loading arrangements.
Production batch planning also affects the quotation. A project delivered in one batch may have a different cost profile than a project delivered in multiple phases.
Buyers should confirm total area, panel length and delivery schedule before comparing quotations.
Accessories and Openings
Accessories are a common source of quotation differences. Trims, flashings, fasteners and sealants may be included in one quote and excluded in another. Openings for doors, windows, vents or equipment require additional fabrication and may affect the panel layout.
Bingfa can quote accessories together with the panels. The exact scope should be confirmed during quotation. Buyers should ask which accessories are included and which are excluded.
What Is Actually Included in the Quotation?
Sandwich panel quotations can cover different supply scopes. The four common levels are:
A. Panel-only supply — Panels with standard packing, without accessories or freight unless otherwise stated.
B. Panels + accessories — Panels plus trims, flashings, fasteners and sealants where specified.
C. Building-envelope package — Panels, accessories and related enclosure components for the roof and wall system.
D. Complete building / project scope — Panels plus structural steel, enclosure and other project items.
Two total quotations cannot be compared fairly until their included scope is aligned. Bingfa includes packaging in the supply quotation. Accessories can be quoted together. Installation is not included by default.
Table 2: Quotation Scope Checklist
| Item | Included / Confirm | Typical Boundary to Check |
|---|---|---|
| Panels | Confirm | Core, thickness, facing, profile, quantity |
| Accessories | Confirm | Trims, flashings, fasteners, sealants |
| Packing | Included by Bingfa | Confirm packing method and protection level |
| Trade term | Confirm | EXW, FOB or CIF |
| Freight | Confirm | Included or excluded depending on trade term |
| Documentation | Confirm | Certificates, inspection records, packing list |
| Installation | Not included by default | Confirm separately if required |
| Openings | Confirm | Special fabrication and interface details |
| Special profiles | Confirm | Non-standard profiles or joint systems |
EXW vs FOB vs CIF: Where the Cost Boundary Changes
EXW, FOB and CIF change which transport-related costs sit inside the quotation. State the agreed place or port and the Incoterms edition used. Compare those details together with the panel specification and quantity.
EXW — named place. Panels are made available at the agreed factory or other named place, ready for collection. Loading, export clearance and onward transport are normally the buyer's responsibility under EXW. Confirm any separately agreed supplier assistance.
FOB — named port of shipment. The quotation includes export clearance and the costs of placing the panels on board the nominated vessel at the agreed shipment port. Main sea freight is outside the seller's FOB price. Any insurance the buyer chooses to arrange should be checked separately.
CIF — named port of destination. The quotation includes export clearance, freight and the required cargo insurance to the agreed destination port. Paying for those items does not mean the seller bears risk until arrival: under CIF, risk transfers when the goods are loaded on board at the shipment port.
FOB and CIF apply to sea or inland waterway transport. For containerized panels, confirm that the selected term matches the actual handover arrangement. Import clearance, duties and taxes are outside these quotation bases. Destination handling and unloading depend on the applicable quotation and carriage contract, so confirm those charges explicitly. Bingfa's on-site installation is not included by default and must be separately quoted or coordinated if required.
When comparing quotations, confirm the same trade term and named place or port. A difference in freight or other included services is not necessarily a difference in the panel price itself.
What Buyers Should Send for an Accurate Quote
To receive an accurate sandwich panel quotation, buyers should provide the following information. The more complete the information, the more comparable the quotation will be.

| Trims / flashings | Affects supply scope | Required trim and flashing items |
| Fasteners / accessories | Affects supply scope | Required fasteners, sealants and closures |
| Project location | Affects design inputs and logistics | Country, city and site location |
| Destination port | Affects freight boundary | Port of discharge or delivery location |
| Trade term | Affects cost boundary | EXW, FOB or CIF |
| Required documents | Affects documentation scope | Certificates, inspection records, packing list |
| Installation required | Affects scope and quotation | Yes or no — confirm separately if required |
If some information is not yet confirmed, an initial review can begin with the available details. Additional information can be provided as the project progresses.
If you have your panel application, core material, thickness, quantity and destination information ready, send them for a supply-scope review. If some details are not yet confirmed, the available information can still be reviewed first.
How to Compare Two Sandwich Panel Quotations Fairly
Before comparing two sandwich panel quotations, align the following items:
- Core material
- Panel thickness
- Facing steel specification
- Coating and finish
- Effective coverage
- Roof or wall profile
- Joint system
- Total quantity
- Panel length
- Accessories included
- Packing scope
- Freight boundary
- Trade term (EXW / FOB / CIF)
- Installation scope
- Exclusions
- Documentation requirements
Once the scope is aligned, the comparison becomes meaningful. A lower total may simply exclude items that the higher total includes. A higher total may include packing, accessories or freight that the lower quote does not.
For a detailed quotation comparison workflow, refer to the Quotation Comparison Guide.
FAQ
1. What affects sandwich panel cost?
Sandwich panel cost depends on core material, panel thickness, facing steel specification, coating, profile, joint system, panel length, quantity, accessories, packing, trade term, freight boundary, documentation and installation scope. Each factor changes the quotation in a different way. The confirmed specification and supply scope determine the final price.
2. Does core material affect the quotation?
Yes. EPS, PU/PUR, PIR and Rock Wool have different production costs, availability and performance characteristics. The required core material should be confirmed before quotation. A project that allows a choice of core material may have a different cost profile than a project requiring a specific material.
3. Does panel thickness affect cost?
Yes. Thicker panels use more core material. Facing steel thickness, grade and coating are separate specifications that also affect the quotation. The required thickness should be confirmed based on insulation, structural or fire-related requirements. A thicker panel is not automatically more expensive in every comparison — the total scope also matters.
4. Are accessories included in a sandwich panel quotation?
Accessories can be included when specified. Trims, flashings, fasteners and sealants may be included in one quotation and excluded in another. Buyers should confirm which accessories are included and which are excluded. Bingfa can quote accessories together with the panels.
5. Is packing included in Bingfa’s sandwich panel quotation?
Yes. Packaging is included in the supply quotation. The packing method depends on panel length, surface protection requirements and transport conditions. Buyers should confirm any special packing requirements before quotation.
6. Are shipping and installation included in the panel price?
Shipping and installation are not automatically included. The trade term (EXW, FOB or CIF) defines where the supplier’s cost boundary ends. Installation is not included by default and can be separately quoted or coordinated depending on the project. Buyers should confirm both the trade term and installation scope.
7. What information is needed for an accurate sandwich panel quote?
To receive an accurate quotation, provide the application, core material, panel thickness, facing steel requirement, coating, profile, panel length, total area, drawings, opening details, accessories, project location, destination port, trade term, required documents and installation requirement. The more complete the information, the more comparable the quotation will be.
Send your panel application, core material, thickness, quantity, destination and trade term requirements so Bingfa can review the supply scope and prepare a quotation based on the confirmed project information. Packaging is included. Accessories can be quoted together. Installation is not included by default and can be separately confirmed if required.
