Galvanized, powder-coated tubular steel panels set between posts make up a backyard metal fence, sold in slat, corrugated, and ornamental styles.

The post depends on where it stands: a patio takes the 74-inch surface-mount post, while 7-foot configurations require the 114-inch in-ground post, so settle height and location before ordering.

Slat or Corrugated Profile

The comparison lays out LINE slats, ribbed corrugated panels and traditional ALEKO styles.

Modern Yard sells both profiles in Private Black, each laid out at nominally 8 ft wide by 6 ft high.

LINE slats suit a modern house with clean horizontal lines, while corrugated panels add texture and a ribbed surface that breaks up a long run. For a traditional home, ALEKO’s wrought-iron-style and picket designs fit better than either.

LINE Corrugated ALEKO
Direction Horizontal slats Interlocking vertical panels Wrought-iron-style or picket
Piece size 1 by 4 inches, 94½ inches long 69½ inches long n/a
Look Streamlined, linear Ribbed Traditional
Layout 8 ft by 6 ft 8 ft by 6 ft n/a

Privacy and Gap Spacing

A backyard fence separates the yard while leaving the choice of screening to its design.

Two options give full screening: the LINE full-privacy layout, a nominal 8 ft wide by 6 ft high, and vertical corrugated panels, which interlock into one closed surface. Neither leaves a sightline.

Only LINE lets you loosen things up, because its other layouts take half-inch or nominal one-inch gaps with the specified hardware. Corrugated has no gap setting.

ALEKO’s open ornamental and security-oriented designs sit at the other end. They define the boundary but let anyone see through.

For a yard where blocking the view matters, pick full-privacy LINE or corrugated and skip the open ALEKO styles. I’d choose LINE if you might want a gapped layout later.

Steel Type and Finish

Hollow steel fence members show the Private Black coating and a zinc-coated edge.

Both Modern Yard infill types are galvanized steel finished in Private Black powder coat, so the metal itself won’t separate them.

Galvanizing puts a zinc layer on the steel to resist rust, and the baked-on powder coat sits over it as a hard, even color layer. Together they give a backyard fence two layers of protection against weather and scrapes.

Tubular steel is hollow, which makes it lighter and more affordable than solid steel while still strong.

For a residential yard, I’d pick galvanized, powder-coated tubular steel over solid bar. Solid stock is heavier to carry and set, and a backyard fence rarely needs that extra mass.

Surface-Mount or In-Ground Posts

The diagram pairs a welded base plate with a surface-mount post and ground-set posts.

Where the fence stands decides the post.

A patio or concrete slab calls for the 74-inch surface-mount post, which has a welded base plate. Anywhere you can set posts in the ground, use the in-ground lengths.

Post Length Base Where it works
Surface-mount 74 inches Welded base plate Patios and slabs
In-ground 98 inches n/a Ground-set layouts
In-ground 114 inches n/a Ground-set layouts, including seven-foot fences

If you plan a tall fence, remember that seven-foot metal configurations use the 114-inch in-ground post, so the surface-mount post is not an option for them.

Gates and Matching Parts

A metal fence and gate stand together, with matching profiles across the entrance.

Steel versus aluminum isn’t one choice on these fences, because the two metals split the work. The fixed infill is steel, while the gate leaf on a LINE profile is aluminum.

Corrugated gates mix them: an aluminum frame holding steel panels. Buy the gate in the same profile as the fence, and the pairing is already settled for you.

Order the matching posts, rails, connectors and hardware from the same line so the pieces fit without improvising. ALEKO also sells gate openers and a Duplex System meant to protect gates against extreme weather.

I’d ask about both if your yard gets storms or hard winters, or if you want the gate to open without a hand on it.

Security, Durability and Upkeep

The upkeep diagram highlights fence inspection points, including welds, posts and chipped finish.

ALEKO builds security into the look of the fence: pickets, pointed spear tops, decorative finials, hoops and scroll details, plus anti-climb coatings.

Spear tops and finials make the top rail hard to grip, so I’d choose them over flat tops on any side facing an alley or street.

Heavy-duty galvanized steel with a zinc coating resists rust and corrosion, and it is built for heavy rain, snow and extreme temperatures.

Upkeep is light. Wash the fence occasionally and inspect it, looking at the welds, the base of each post and any spot where the finish has chipped.

Touch up chips before bare steel sits exposed to rain. No lifespan in years is published, so treat any number you see quoted as a guess.

Fencing on a Slope

A backyard fence follows a slope in level sections, creating a stepped line.

Stepped fencing is the method for a sloped backyard, and ALEKO describes it plainly:

With stepped fencing, the slope is divided into terraced or leveled sections, and each fence panel is installed horizontally, creating a "stepped" effect that follows the incline in increments.

— Aleko Products

Every panel stays level, so plan to level or terrace the ground at each post location before you set a post.

Check local zoning and HOA rules on fence height before you buy anything, because a violation can mean fines. A DIY kit includes what a home project needs, but line up a couple of helpers for the slope.

What the Packs Contain

Fence components are shown together, including panels, connectors and hardware.

Each system ships in pieces, so the packs and the hardware are counted separately:

  • LINE slat pack: 2 steel slats and 4 PVC end caps. No connectors or screws are listed, so plan on a hardware kit too.
  • Corrugated pack: 3 steel panels and 3 aluminum aligners.
  • LINE hardware kits: base connectors, L connectors and screws in both versions.
  • Full-privacy kit: adds EVA.
  • Semi-privacy kit: adds stackable connectors.
  • ALEKO: panels, brackets, fixings, top rails and tension bars. Gate openers are sold for the same line.

I’d check the box against this list before the first post goes in. A missing connector is easier to sort out while the delivery is still fresh.

Fire Test and Warranty

Metal fence panels stand near a grill and fire pit beside a neighboring shed.

Metal fence panels near a grill, fire pit or neighbor’s shed raise a fair fire question. Modern Yard publishes an ASTM E84-24 report that records surface-burning results for an identified myFireGuard corrugated panel sample and finish.

The report speaks only for that panel and finish, so match the product name and finish on your order to the ones in the report.

The limited warranty covers eligible parts and factory finishes, and "eligible" is the word to watch.

Coverage length, exclusions and whether installation scratches count are questions for the written terms, so read the warranty terms before you buy, not after a finish fails.

Frequently Asked Questions

Recommended Products

Which backyard metal fence style fits my yard?

Pick LINE for a modern house with clean horizontal lines, or corrugated for a ribbed vertical surface that breaks up a long run.

Both come in Private Black at a nominal 8 ft wide by 6 ft high. A traditional home usually looks better with ALEKO’s wrought-iron-style or picket designs.

What finish does a Modern Yard metal fence have?

Private Black powder coat over galvanized steel.

The zinc layer under the coating resists rust, and the baked-on powder coat adds a hard, even color. Both infill types share this finish.

Can LINE and corrugated fences use the same spacing?

No.

LINE comes in a full-privacy layout and in layouts with half-inch or nominal 1-inch gaps, using the specified hardware. Corrugated panels interlock into one closed surface and have no gap setting.

How does steel compare with aluminum on a metal fence?

The fixed fence infill is steel on both profiles, and aluminum shows up in the gates.

A LINE gate leaf is aluminum, and a corrugated gate pairs an aluminum frame with steel panels. Buying the gate in the same profile as the fence settles the pairing.

What comes in a LINE or corrugated infill pack?

A LINE pack holds 2 steel slats and 4 PVC end caps.

A corrugated pack holds 3 steel panels and 3 aluminum aligners. The LINE pack lists no connectors or screws, so order a LINE hardware kit as well.

Can I install a backyard metal fence on a slope?

Yes, using the stepped method.

ALEKO divides the slope into terraced or leveled sections and installs each panel horizontally, so the fence follows the incline in steps. Plan to level or terrace the ground at each post location before setting the post.

Can I install a residential metal fence myself?

Yes. ALEKO says its home fencing kits include what a DIY project needs, and it suggests having a couple of extra people to help.

It recommends professional installation for larger projects, and a sloped yard is a good reason to line up helpers.

Will a galvanized, powder-coated metal fence rust?

It is built to resist rust, but chips in the finish can still expose bare steel.

Wash the fence now and then, and check the welds, the base of each post and any chipped spots. Touch up chips before the exposed steel gets rained on.

How long will a metal fence gate last?

No lifespan in years is published.

ALEKO says its galvanized, powder-coated steel gates are durable and can last for years with regular cleaning and touch-ups. Treat any specific number you see quoted elsewhere as a guess.

What is the difference between tubular steel and solid steel fencing?

Tubular steel is hollow, so it is lighter and more affordable than solid steel while still strong and durable.

Solid stock is heavier to carry and set. For most residential backyards, galvanized, powder-coated tubular steel is the better pick.
