Metal Siding Panels: Types, Gauges, and 2026 Cost Per Square Foot

By The Roofing Brief Team. Last reviewed: October 2026.

Metal siding is steel or aluminum wall cladding sold as formed panels, and installed it runs about $4 to $16 per square foot in 2026 per Fixr’s April 2026 cost guide, with steel at $7 to $16 and aluminum at $6 to $10 per HomeGuide. The same panels clad homes, barns and commercial buildings, and four decisions set the price: profile (the shape of the panel face), material (steel or aluminum), gauge (thickness) and finish (the paint system that decides how long the color lasts). Profile moves the number most: exposed-fastener corrugated and PBR panels run $7 to $12 installed, while concealed-fastener standing seam runs $10 to $16, per Fixr.

Quick Answer: What Metal Siding Panel Should You Buy?

Match the panel to the building first and the budget second. Agricultural walls suit 29 or 26 gauge ribbed (PBR or R-panel) steel at $7 to $12 per sq ft installed, homeowners who want a lasting look pick 26 gauge board-and-batten ($9 to $14) or standing seam ($10 to $16) with a PVDF finish, and homes within 1,500 feet of salt water lean to aluminum at $6 to $10 because Galvalume steel warranties commonly exclude that zone, per McElroy Metal.

• Budget agricultural or shop walls (pole barn metal): 29 or 26 gauge ribbed or PBR steel panels, exposed fastener, $7 to $12 per sq ft installed (Fixr); unpainted Galvalume steel starts near $4 per sq ft (Fixr’s $4 to $12 range).
• Residential look you will keep for decades: 26 gauge board-and-batten ($9 to $14) or 24 gauge standing seam ($10 to $16) with a PVDF (Kynar 500) finish, per Fixr.
• Coastal or salt-air homes: aluminum panels, $6 to $10 per sq ft installed for smooth boards and $4 to $7 for corrugated aluminum (HomeGuide).
• Modern farmhouse or rustic accent walls: 7/8-inch corrugated steel, the exposed-fastener wave, $7 to $12 per sq ft installed (Fixr).

Decision Table: Which Metal Siding to Buy, by Threshold

Metal Siding Panel Profiles Compared

The profile is the single biggest driver of both appearance and price. There are two families: exposed fastener panels (screws go through the face of the panel) and concealed fastener panels (clips or seams hide the fasteners). Exposed fastener panels are cheaper and faster to install; concealed fastener panels cost 35% to 45% more but keep the fasteners out of the weather, per HomeGuide. Our guide to ribbed steel siding compares the exposed fastener rib profiles, from R-panel and PBR to corrugated.

Corrugated panels

Corrugated steel, usually sold as a 7/8-inch wave, is the exposed-fastener look behind modern farmhouse and rustic commercial walls, and Fixr prices it at $7 to $12 per sq ft installed. Screws go through the face of the wave. It forgives slightly uneven framing and comes in steel or aluminum; HomeGuide prices corrugated aluminum lower, at $4 to $7 per sq ft installed.

Ribbed, R-Panel, and PBR

Ribbed panels use taller, squared trapezoidal ribs, which give them more spanning capacity than corrugated at the same gauge. PBR (Purlin Bearing Rib) is a specific ribbed profile with a bearing leg at the panel lap that sits on the purlin for a stronger overlap connection. MBCI’s PBR sheet lists 36-inch coverage, 1-1/4 inch rib height, ribs 12 inches on center and 26 gauge standard (24 and 22 optional), which makes it the fastest way to clad a large pole barn or steel shop wall. They are the same trapezoidal shapes catalogued among common metal roofing types, formed from the same coils.

Board-and-batten

Metal board-and-batten mimics traditional wood siding with steel. It is sold in 26 or 29 gauge steel in widths from 8 to 24 inches, Fixr prices it at $9 to $14 per sq ft installed, and it is the profile to pick when you want metal siding that does not read as agricultural.

Standing seam

Standing seam is the premium option at $10 to $16 per sq ft installed, per Fixr. Panels interlock at a raised vertical seam with a fully concealed fastener system, so no screws show on the face, and HomeGuide puts concealed-fastener labor 40% to 50% above exposed-fastener labor. It is the same concealed-seam system behind premium standing seam metal roof cost figures, applied to walls.

Metal Siding Gauge: 29 vs 26 vs 24

Gauge is the thickness of the steel. The counterintuitive rule: the higher the gauge number, the thinner the metal. Metal America’s gauge chart lists nominal thickness of 0.014 in for 29 gauge, 0.018 in for 26 gauge and 0.024 in for 24 gauge. Exact thickness depends on the mill and the metallic coating: Western States Metal Roofing notes 26 gauge can run from .0179 to .0217 in, so ask for the decimal thickness on the quote, not just the gauge number. On homes, IRC Table R703.3(1) sets 29 gauge as the minimum for steel lap siding at 16-inch stud spacing.

Worked example: HomeGuide puts steel siding materials and supplies at $4 to $6 per sq ft, so a 2,500 sq ft wall carries $10,000 to $15,000 in material. A 10% to 25% step from 29 to 26 gauge adds roughly $1,000 to $3,750 on that job. That is why 26 gauge is the default for walls that need to resist oil-canning, hail and wind, and 29 gauge is the call when budget decides and the building is agricultural.

Steel vs Aluminum Panels

Most metal siding is steel, but aluminum is the correct choice in specific conditions. Steel is stronger, more dent resistant and runs $7 to $16 installed per HomeGuide. Aluminum runs $6 to $10 and does not rust through, which makes it the coastal and salt-air pick. On warranty, McElroy Metal states Galvalume (55% aluminum, 45% zinc coated steel) routinely carries a 25-year substrate warranty, aluminum substrates typically carry none, and Galvalume warranties exclude structures within 1,500 feet of the coast.

Finish: The Spec That Decides How Long the Color Lasts

Two panels of the same profile and gauge can carry different finishes, and the finish decides whether the color holds or chalks out. Metal siding uses two mainstream paint systems: SMP, the value coating (Metal America, for example, runs Sherwin-Williams WeatherXL SMP across its gauges), and PVDF (Kynar 500 or Hylar 5000), the premium coating. Arkema’s specification requires Kynar 500 finishes to contain at least 70% PVDF resin by weight and meet AAMA 2605.

• SMP (silicone-modified polyester): the value coating, priced 15% to 40% below PVDF panels per HomeGuide, with color that drifts faster in sun.
• PVDF (Kynar 500 / Hylar 5000): the premium coating, with paint warranties that typically run 30 to 40 years per Fixr.

Read the warranty line by line. Per Western States Metal Roofing, a headline “40-year” PVDF warranty usually covers film adhesion (tested under ASTM D3359) for 40 years, while fade (measured in Hunter Delta E units) and chalk (rated 1 to 10 under ASTM D4214) are covered for 15 to 30 years. Ask for the Delta E and chalk-rating thresholds in writing.

The Roofing Brief Cost Synthesis

Pulling the 2026 pricing together, installed metal siding spans about $4 to $16 per square foot (Fixr) and Homewyse puts the May 2026 national average at $8.82 to $14.67 per sq ft. Labor is 30% to 60% of the total per HomeGuide and Fixr, in line with broader roof cost per square foot benchmarks; HomeGuide splits steel into $4 to $6 materials and $3 to $10 labor per sq ft.

The 1,500 sq ft column multiplies each published range by 1,500. Old siding removal adds $0.70 to $2.00 per sq ft and new trim $1 to $5 per linear foot, per HomeGuide; a general contractor adds 13% to 22% per Homewyse.

Coverage Width and Waste: Why the Panel Sticker Price Lies

Metal wall panels are sold by the panel or by the linear foot, but they are installed by coverage width, not total width. A 36-inch PBR panel overlaps its neighbor by one rib, so its net coverage is 36 inches by design, but a corrugated panel that is 26 inches wide may only cover 24 inches after the sidelap. Always price by coverage width, and add 5 to 10 percent for waste from cuts around windows, doors, and corners. On a simple gable wall, 5 percent is realistic; on a cut-up wall with many openings, budget 10 percent or more.

Decision Matrix: Pick Your Panel in One Step

Lowest-cost agricultural walls take 29 gauge ribbed steel, quality barns step up to 26 gauge, a residential look calls for 26 gauge board-and-batten in PVDF, premium builds use 24 gauge standing seam, and sites within 1,500 feet of salt water use aluminum. Each row pairs the profile, gauge, material and finish that fit.

Frequently asked questions

How much do metal siding panels cost per square foot in 2026?

Installed, metal siding runs about $4 to $16 per square foot in 2026 per Fixr. Exposed-fastener corrugated and PBR steel run $7 to $12, aluminum smooth boards $6 to $10 (HomeGuide), board-and-batten $9 to $14 and standing seam $10 to $16 (Fixr). Labor is typically 30 to 60 percent of that total.

What is the best gauge for metal siding?

26 gauge (about 0.018 inch nominal per Metal America) is the default for homes and quality barns. It resists oil-canning, hail and wind better than 29 gauge for about 10 to 25 percent more cost, depending on the source. Choose 29 gauge only for budget agricultural buildings, and 24 gauge for standing seam or severe weather zones.

Is steel or aluminum siding better?

Steel is stronger and runs $7 to $16 per sq ft installed per HomeGuide, so it fits most homes and barns. Aluminum ($6 to $10) does not rust through, so it fits buildings within 1,500 feet of salt water, where McElroy Metal says Galvalume substrate warranties are excluded.

What is the difference between metal siding and metal roofing panels?

They are often the same profiles (corrugated, PBR, standing seam) formed from the same coils; MBCI sells its PBR panel for both roofs (minimum slope 1/2:12) and walls. Siding panels carry less snow and water load, so many barns use identical panels for roof and walls and order heavier gauge for the roof.

Can you install metal siding panels yourself?

Exposed-fastener panels (corrugated, ribbed, PBR) are the most DIY-friendly because they screw directly through the face into framing or girts. Standing seam is best left to a pro because of the concealed clip system, and HomeGuide puts its labor 40 to 50 percent above exposed-fastener labor. Either way, order trim (corners, J-channel, base) with the panels; HomeGuide prices new trim at $1 to $5 per linear foot.

How long do metal siding panels last?

Metal America cites 40 to 70 years or more for a properly installed metal siding system. The finish usually limits it: PVDF film adhesion is warranted for 20 to 40 years but fade and chalk often for only 15 to 30 years, per Western States Metal Roofing. Galvalume steel typically carries a 25-year substrate warranty, per McElroy Metal.
