Corrugated metal fence cost & panel count
A corrugated metal fence — often called a corrugated iron fence — is steel roofing sheet turned into a fence face. Its material count follows one number: the net coverage width of the sheet.
Corrugated metal has moved from farm sheds to design-forward backyards: the wavy galvanized (or rusted Corten-look) sheet makes a solid, low-maintenance privacy fence with an industrial edge. Pricing one is different from a picket fence, because you are buying sheets plus a frame — and both counts fall out of simple division.
Corrugated iron, corrugated steel, corrugated metal — same fence
The names are regional, not technical. “Corrugated iron” is the traditional (and Australian/British) term; in the US the same product is sold as corrugated steel or metal panel — a galvanized or Galvalume-coated steel sheet, sometimes painted, rolled into the familiar wave. Whatever the label, the fence build and the math below are identical.
The parts of a corrugated metal fence
- Sheets (panels) — the metal face. A common sheet is ~26" wide but covers ~24" net once the waves overlap; lengths of 8, 10 and 12 ft are typical. Run vertically for the classic look, sheets are cut to the fence height.
- Posts — wood 4×4s or steel pipe. Because the face is solid, it catches wind like a sail: spacing is usually kept at 6 ft rather than the 8 ft an open fence gets away with (a labeled planning typical).
- Rails / girts — the horizontal framing the sheets screw to: 2 for fences to ~4 ft, 3 for 5–6 ft, same rule as any fence.
- Fasteners — metal-to-wood screws with neoprene washers, on the manufacturer’s spacing; plus a top channel or wood cap if you want the cut edge covered.
Counting the sheets
Sheets repeat at their net coverage width, so the count is the picket formula with a wider board:
sheets = ceil(line × 12 ÷ net coverage width in)
The metal fence panel count calculator runs this for any panel or sheet width — enter the net coverage, not the overall width, or the fence comes up short.
Worked example — 100 ft, 6 ft tall
A 100 ft privacy run, 6 ft high, sheets with 24" net coverage, posts at 6 ft, 3 rails:
- Sheets: ceil(100 × 12 ÷ 24) = 50 sheets (cut to 6 ft, or one 12 ft sheet yields two)
- Sections: ceil(100 ÷ 6) = 17 → 18 posts for a straight run (plus gate, end and corner posts — the post calculator adds them)
- Rails: 17 × 3 = 51
- Concrete: at ~3 bags of 60 lb per hole, 18 × 3 = 54 bags (concrete per post)
What does it cost?
This site holds no price list — you price the count above from your own quotes:
total = sheets × your $/sheet + posts, rails & concrete + fasteners + labor, ×(1 + contingency)
As a sanity frame, the material sits between chain-link and wood privacy on most bids: the sheet itself is cheap per square foot, and the frame (posts, rails, concrete, labor) is where most of the money goes — which is why the 6 ft post spacing matters more to the budget than the sheet price. Assemble the itemized total with the fence installation cost estimator and compare rates with the cost-per-linear-foot tool.
What to check before you build
- Wind. A solid 6 ft metal face takes real wind load — tighter post spacing, deeper holes and, on exposed sites, an engineer’s sizing are the difference between a fence and a sail.
- Edges. Cut sheet edges are sharp; a top channel, cap rail or hemmed edge belongs anywhere people or pets pass.
- Heat and glare. Bare galvanized sheet reflects; painted or weathered-steel finishes are the usual fix in a tight yard.
- Rules. Some HOAs and local ordinances treat metal fencing differently from wood — confirm before buying 50 sheets.
- Drainage at grade. Keep the sheet an inch or two off the soil so the cut edge does not sit wet — a kickboard closes the gap.
This is a material-quantity and planning-cost guide, not a bid or a structural design. Confirm sheet coverage width and lengths against your product, price the parts from your own quotes, check wind exposure and local rules, call 811 before you dig, and get itemized written quotes from a licensed, insured fencing contractor.
