Concertina razor wire is commonly used on industrial perimeters, warehouse compounds, utility sites, mining areas and other restricted-access projects where buyers need a compact perimeter material with strong visual deterrence. The product is more specification-sensitive than ordinary fence rolls because blade type, coil diameter, core wire and clip arrangement all affect the final quotation.
A typical inquiry such as "BTO-22, 500mm, 100 coils" is still incomplete. It does not explain blade material, core wire diameter, coil loops, single coil or cross type, clip requirement, packing method or destination. This guide explains what buyers should confirm before comparing concertina razor wire quotations.
What Buyers Should Confirm First
Before asking for price, confirm whether the project needs single coil concertina or cross type concertina. Single coil can be quoted as individual coils. Cross type needs clip quantity and connection details, so the quotation basis is different.
Buyers should also confirm whether the order is for coil supply only or for a wider fence package with chain link fence, barbed wire, posts or accessories. Mixed container loading is common, but the packing plan should be clear.
Blade Type: BTO and CBT
Blade type is one of the first details buyers should define. BTO blade types are commonly used for general perimeter supply, while CBT blade types are larger and usually selected for higher-requirement project specifications.
The common buyer mistake is to mention only "razor wire" without blade type. A quotation for BTO-22 and a quotation for CBT-65 are not comparable because blade size, strip thickness, roll weight and packing can be very different.
| Blade Type | Buyer Context | RFQ Note |
|---|---|---|
| BTO-10 / BTO-18 | Light perimeter or market stock requirement | Confirm local buyer preference before ordering |
| BTO-22 | Common export type for many perimeter projects | Usually a practical starting point for RFQ comparison |
| BTO-30 | Larger blade requirement | Confirm coil weight and packing method |
| CBT-60 / CBT-65 | Project-defined heavy blade requirement | Send the project document or sample reference if available |
When the project has a required blade drawing or sample, include it in the RFQ. Blade names can be understood differently across markets, while a photo or drawing reduces ambiguity.
Coil Diameter and Loop Count
Coil diameter defines the physical size of the concertina roll after opening. Common buyer requests include 450mm, 500mm, 700mm and 960mm, but the correct size depends on the installation plan and project document.
Loop count is also important. Two coils with the same diameter may contain different loop counts, which changes the material usage and stretched length. If a buyer compares price without loop count, the cheaper offer may simply contain less material.
| Coil Detail | What to Confirm |
|---|---|
| Coil diameter | 450mm, 500mm, 700mm, 960mm or project-defined size |
| Loop count | Number of loops per coil |
| Stretched length | Expected coverage after installation |
| Packing compression | Whether coils are compressed for shipping |
Core Wire and Blade Material
The core wire holds the blade tape and gives the coil its structure. Buyers should specify core wire diameter, material and surface finish. For standard export orders, galvanized core wire is common. For special environments, buyers may request stainless steel or a project-defined material.
Blade material should be confirmed separately from the core wire. If the buyer needs galvanized blade tape, stainless blade tape or a specific strip thickness, it should be written clearly.
Avoid using only one phrase such as "stainless razor wire" unless the core wire, blade tape and clips are all intended to be stainless. If only one component is stainless, write that component clearly. For related material logic, see the stainless steel 304 vs 316 buying guide and galvanized iron wire buying guide.
Single Coil or Cross Type
Concertina razor wire can be supplied as single coil or cross type. The difference affects clips, packing and installation.
Single coil means each coil is supplied independently. It is often used when the buyer needs coil material for wall-top or fence-top installation.
Cross type means adjacent coil loops are connected by clips. This creates a denser structure and requires clip material, clip quantity and connection spacing to be included in the quotation.
| Concertina Type | Clip Requirement | Buying Note |
|---|---|---|
| Single coil | Usually no clips between coils | Quote by coil diameter, loop count, blade type and packing |
| Cross type | Clips are required | Confirm clip material, quantity and connection spacing |
If a buyer needs cross type but does not mention clips, the supplier may quote single coil by default. This is one of the most common reasons for price differences.
Clips: Small Parts That Affect the Whole Order
Clips are small, but they are not optional for cross type concertina. They connect adjacent loops and help maintain the final structure after stretching.
The RFQ should include clip material, approximate quantity and packing method. If the concertina uses stainless steel material, the clip material should be discussed as well. For export orders, clips should be packed in clearly labeled cartons or bags so they are easy to count and distribute at the site.
Export Packing and Loading Proof
Concertina razor wire should be packed in a way that controls spring-back, protects the surface and keeps warehouse handling practical. Common packing options include compressed coils, woven bag wrapping, carton packing, pallet packing and mixed container loading.
For larger orders, buyers should ask for packing photos, label confirmation and loading proof. If the order is mixed with barbed wire, chain link fence or other fence materials, the loading plan should separate sharp coils, fabric rolls, panels and accessories clearly. For shipment preparation, use the wire mesh fence export packing checklist.

Frequently Asked Questions
What is the most common concertina razor wire type for export?
BTO-22 with a medium coil diameter is commonly requested for many export markets, but the best choice depends on the buyer's project document, local market expectation and installation plan.
Why do quotations for the same coil diameter differ so much?
The offers may use different blade types, strip thickness, core wire diameter, loop count, clip quantity or packing method. Always compare the same specification basis before choosing a supplier.
Do I need clips for every concertina razor wire order?
Not always. Single coil orders may not need clips between coils. Cross type concertina requires clips, so the clip material and quantity should be included in the RFQ.
Can concertina razor wire ship with barbed wire or fence rolls?
Yes. Mixed container loading is common for fence distributors and project buyers. The packing plan should separate concertina coils, barbed wire rolls, chain link fence fabric, panels and accessories clearly.
What should I send before requesting a quote?
Send blade type, coil diameter, loop count, core wire diameter, material, single coil or cross type, clip requirement, packing method, quantity and destination. If a project drawing or photo is available, include it.
Conclusion: Make the Specification Comparable
Concertina razor wire quotations become much easier to compare when the buyer defines the specification basis before asking for price. Blade type, coil diameter, core wire, clips, loop count and packing all affect the final offer.
For bulk concertina razor wire orders, send your specification, packing preference, quantity and destination before asking for price.
