Technical details
Commonly specified reference configurations for quotation. Select a size below; KUNYU confirms the supply dimensions, material and tolerances on the quotation and order drawing.
| Construction | Connected, overlapping loops arranged in a flat plane |
|---|---|
| Nominal strip height | 500 / 700 / 900 mm |
| Reference length per unit | 15 m |
| Core-wire diameter | 2.5 mm nominal |
| Blade-tape thickness | 0.5 mm nominal |
| Blade profiles | BTO-10 / BTO-22 / BTO-30 reference profiles |
| BTO-22 blade geometry | 22 mm length × 15 mm width; 34 mm pitch |
| Material options for enquiry | Hot-dip galvanised steel; stainless steel 304 or 316 |
| Loop joining | Clipped overlaps; loop arrangement shown on the selected drawing |
| Mounting interface | Wall-top or fence-side mounting, with matching brackets or tie/clip connections |
| Size notation | Height × extended strip length; 500 mm × 15 m is not a 500 mm core-wire diameter |
| Packing options for enquiry | Protective paper and woven outer bag; bundled units or pallet packing by quotation |
| Order unit | 15 m strip units or total linear metres; state which unit is used |
| Nominal height (mm) | Unit length (m) | Core wire (mm) | Tape (mm) | Reference profile |
|---|---|---|---|---|
| 500 | 15 | 2.5 | 0.5 | BTO-22 |
| 700 | 15 | 2.5 | 0.5 | BTO-22 |
| 900 | 15 | 2.5 | 0.5 | BTO-22 |
The listed dimensions are reference RFQ configurations. Overlap, fixing points and any cutting allowance follow the project layout.
| Blade profile | Core wire (mm) | Tape (mm) | Blade length (mm) | Blade width (mm) | Pitch (mm) |
|---|---|---|---|---|---|
| BTO-10 | 2.5 | 0.5 | 10 | 13 | 26 |
| BTO-22 | 2.5 | 0.5 | 22 | 15 | 34 |
| BTO-30 | 2.5 | 0.5 | 30 | 18 | 45 |
Nominal reference dimensions. Blade codes can describe different tooling profiles: for example, BTO-22 is also sold with a 16 mm blade width and 35 mm pitch. Specify the complete dimension set; tolerances and alternative tape thicknesses are agreed on the order drawing.
The product
Flat wrap razor wire connects overlapping loops in a largely flat arrangement. The vertical strip height, supplied length and overlap pattern describe this product more clearly than a coil diameter alone. Provide the fence or wall layout and any projection limit so the strip and supporting components can be reviewed together.
Prepare your enquiry
Specify the steel tape, core wire and connecting clips separately. For stainless steel, state the required grade for each component. For galvanised products, include the required coating mass and inspection method in your enquiry.
Request the required wrapping, coil protection, carton or pallet arrangement. Net and gross weight, packed dimensions, minimum order quantity, production timing and delivery terms are confirmed in the quotation for the selected configuration.
Agree checks for the blade profile, tape thickness, core-wire diameter, overall dimensions, connections, finish and packing labels. Send any project-specific test or certificate requirements with the order schedule.
The published selection fields describe information to include in an enquiry. Confirm the final dimensions, tolerances, material and packing in the quotation and order drawing before purchase.
| MOQ and lead time | Confirmed after specification and quantity review |
|---|---|
| Packing and weight | Recorded against the selected configuration |
| Delivery | Provide destination country and port for quotation |
Send your specification, quantity and destination.
Prepare a product enquiryBuyer questions
Both use razor wire, but flat wrap connects the loops in a flat plane. Concertina opens into a three-dimensional coil. Check the required projection, support arrangement and supplied dimensions when comparing them.
It can be reviewed for a gate installation. Provide the gate movement, surrounding clearances, support details and permitted projection so the topping does not conflict with adjacent components.
Yes. Select the required material in your enquiry. The quotation identifies the blade tape, core wire and clip materials individually, including stainless grade or galvanised coating requirements.
The size and material selectors record your requested specification. Availability, tolerances, supplied dimensions and packing are confirmed in the quotation and approved order drawing.
Send the product type, blade profile or drawing, dimensions, material, quantity, destination and required delivery date. Include your packing preference and any matching bracket or fixing requirements.
The size table uses a 15 m unit length with 500, 700 or 900 mm nominal height. State the total fence run and the number of units required; the final joining and cutting allowance depends on the installation layout.
