1. Barbed wire roll length conversion
| Length label | Equivalent | What buyers should check |
|---|---|---|
| 1,320 ft | 80 rod / 402.336 m / ¼ mile | Confirm net wire length and permitted tolerance |
| 80 rod | 80 × 16.5 ft = 1,320 ft | Rod is a length unit, not the number of coils |
| 400 m | Approximately 1,312.34 ft | Not the same order length as 1,320 ft |
| 100 m | Approximately 328.08 ft | A separate metric packing length, not an 80-rod roll |
Conversion basis: NIST length factors — 1 ft = 0.3048 m; 1 rod = 16.5 ft; 1 mile = 5,280 ft. Confirm actual coil length separately.
2. How many rolls are needed for a multi-strand fence?
Rolls = round up [(Σ(run length × strands) + extra wire allowance) ÷ net length per roll]. Use matching units and calculate each wire specification separately. Include ends, joints, cuts and repairs in the allowance.
| Illustrative fence run | Specified strands | Wire before allowance | 1,320 ft rolls before allowance |
|---|---|---|---|
| 1,320 ft | 1 | 1,320 ft | 1 |
| 1,320 ft | 4 | 5,280 ft | 4 |
| 5,280 ft / 1 mile | 5 | 26,400 ft | 20 |
These examples do not prescribe strand count or post spacing. In the one-mile, five-strand case, an illustrative 10% allowance gives 29,040 ft, or 22 coils. Use your approved cutting and joining plan. See the fence cost guide for wider budgeting.
3. Compare the four published 1,320 ft models
| Model | Wire / barb format | Listed roll | Coating basis |
|---|---|---|---|
| 12.5 gauge 2-point | Low-carbon / 2 point | 1,320 ft / 80 rod | Class 3 galvanized |
| 12.5 gauge 4-point | Low-carbon / 4 point | 1,320 ft / 80 rod | Class 3 galvanized |
| 14 gauge high tensile | High tensile / 4 point | 1,320 ft / 80 rod | Galvanized; grade to order |
| 15.5 gauge high tensile | High tensile / 4 point | 1,320 ft / 80 rod | Class 3 galvanized |
All four models list 5 in barb spacing. Compare wire gauges and barb counts separately from roll length; confirm actual strand and barb diameters.
4. How to Compare Barbed Wire Quotes per Roll and per Foot
Compare the same net length, wire diameters and steel grade, barb count and spacing, coating, coil weight, packing and quantity. Use the same destination and delivery terms.
Price per foot = coil price ÷ verified net feet per coil. A lower price per roll can hide less wire. Posts, bracing, gates, installation and site costs are separate unless expressly included.
KUNYU’s published export minimum is 1 × 20GP. Mixed-model loading depends on coil weights, packed dimensions and loading limits; see the container loading guide.
