Choose true 4" x 4" or 5" x 5" posts in 6', 9' or 12' lengths, in black, brown or gray, with a removable steel cap.

Description

Steel Posts for Wood Fences That Won't Rot at the Ground Line

Most wood fences don't fail at the boards. They fail at the posts, where the wood sits in wet soil and concrete and starts to rot, until one post goes and the whole run leans. These galvanized steel posts take the rotting part out of the ground. Keep the wood rails, pickets or framed panels you love, and set them on posts that won't decay, warp or get eaten by insects.

One Flat-Faced Post for Corners, Ends and Inline Runs

Traditional fencing often calls for different posts at corners, ends and T-junctions. These posts are flat on all four faces, so the same post works at every position in the run. That keeps your order simple and gives rails, brackets and panel frames a square, solid surface to mount to. A removable, reinforced steel cap finishes the top of each post.

True 4x4 and 5x5 Steel Fence Post Sizes

Choose a true 4" x 4" post for most residential fences, or a true 5" x 5" post for taller fences, heavy panels and gates. Pick the length by your fence height:

Fence height	Post length	Depth in ground
Up to 4'	6'	About 2'
5' to 6'	9'	About 3'
7' to 8'	12'	About 4'

In cold climates, make sure the bottom of the post sits below your local frost line, and check local building codes before you dig.

Replacing Rotted Wood Posts With Metal

Swapping failing wood posts for steel is the most common reason people buy these. One thing to plan for: these posts are true to size, so a 4" x 4" steel post measures a full 4" on each face, while a wood 4x4 is actually 3.5". In an existing fence, that extra half inch can mean trimming rails slightly to fit between posts. If you're building new, simply lay out your spacing for the true post size.

Setting Metal Fence Posts in Concrete

Set each post in concrete, the same as a wood post. Dig the hole, set the post plumb, pour the concrete and slope the top away from the post to shed water. Because galvanized steel doesn't decay in the concrete collar the way wood does, the posts usually outlast the fence they hold. On sloped or stepped runs, adjust how deep you set each post to bring the tops into line, rather than cutting the steel, which exposes bare edges and voids the coating warranty.

📐 Custom Sizing

Most projects fit the sizes listed on this page — those are what we build, stock and price online.

We do make custom sizes within our standard range, and we quote them case by case. If your run falls between two listed sizes — say you need 7′ 6″ when we list 7′ and 8′ — we can build it. The cost depends on the dimensions, the profile and how much material the cut leaves behind, so custom sizes are not listed or priced on the site. Send us the measurements and we will tell you what is possible and what it costs.

Custom sizes are final sale. A panel cut to your dimensions cannot be restocked or sold to anyone else, so custom-sized orders cannot be returned or exchanged. Please confirm your measurements before you approve the quote.

These products can all be modified on site. Trimming a panel to close out a run is normal work, and you do not need us to do it for you — ask and we will walk you through how to cut and seal it properly so the finish holds up.

Just know that a cut edge is no longer a factory edge: cutting or drilling exposes unprotected steel and voids the steel & coating warranty on that component. Done the right way and sealed properly it will still last — so ask us before you cut.

🏅 Warranty

Steel posts: 40-year warranty against rust, fade and corrosion on the galvanized steel post and its factory finish. Each post is heavy-gauge galvanized steel with a 2.38 mm wall.

Finish: The black, brown or gray factory finish is warranted against fading, chipping and peeling under normal outdoor exposure.

Installation: Proper installation is the installer's responsibility, including the correct concrete mix, post-hole diameter and depth for your soil and frost line, and posts set plumb and level. Damage or premature wear from improper installation is not covered.

Modifications: Cutting, drilling or altering the steel exposes unprotected edges and voids the steel and coating warranty on the modified post.

Care: Rinse posts occasionally to keep the finish clean.

❓ FAQ

Why use a metal fence post instead of wood?
Wood posts rot where they meet the soil and concrete, and once one fails, the fence starts to lean. A galvanized steel post won't rot, split, twist or attract insects, so it holds the fence in line for far longer than a wood post in the same ground.

Can I use metal posts with a wood fence?
Yes, and it's the most common reason people buy them. The posts are flat on all four faces, so wood rails, brackets and wood-framed panels have a square surface to mount to. You keep the look of a wood fence and take the part that rots out of the ground.

What size and length of post do I need?
Use a true 4" x 4" post for most residential fences, and a true 5" x 5" for taller fences, heavy panels and gates. For length, choose 6' posts for fences up to 4', 9' posts for 5' to 6' fences and 12' posts for 7' to 8' fences, so roughly a third of the post sits in the ground.

Why is a steel 4x4 post wider than a wood 4x4?
Lumber is sold by nominal size, so a wood 4x4 actually measures 3.5" x 3.5". These steel posts are true to size, so a 4" x 4" post measures a full 4" on every face. If you're replacing wood posts in an existing fence, the rails between posts may need a small trim to fit.

Do metal fence posts need concrete?
Yes. Set each post in concrete, the same as a wood post, with the bottom below your local frost line in cold climates. Slope the top of the concrete away from the post so water runs off.

Can one post really work at corners and ends?
Yes. Because every face is flat, the same post works inline, at corners, at ends and at T-junctions. You don't need to order or sort different post types for different positions.

How many metal fence posts do I need?
For a straight run, one more post than you have panels or sections. A corner usually keeps the same count, since one post sits at the turn. Add one post for each gate opening and each separate run, because every break in the fence needs its own end post.

Can I cut or drill the posts?
We don't recommend it. Cutting or drilling exposes bare steel, and it voids the steel and coating warranty on that post. To level tops on sloped ground, adjust how deep you set each post instead of cutting it.

Will steel fence posts rust?
The posts are heavy-gauge galvanized steel with a colored finish on top, and they're covered by a 40-year warranty against rust, fade and corrosion. Keep the coating intact and rinse the posts occasionally to keep the finish clean.

What colors do the posts come in?
Black, brown and gray. Not every color is available in every size and length, so check the options on this page for the combination you need before planning a full run.

How are metal fence posts delivered?
We deliver on our own trucks and unload on your property, with no freight terminal and no third-party carrier. Your rate and estimated delivery date show in the estimate box on this page.

Standard-size items (unused, original condition) — returnable within 30 days, subject to a 25% restocking fee. We pick returns up on our own trucks (scheduled around truck availability), at no return-freight charge to you. Because we handle the transport, you're not liable for any transit damage.
Custom, cut-to-size & made-to-order items — because these are built to your exact spec, they are final sale.
Cancellations — full refund before your order enters production; once in production or scheduled to ship, a 25% restocking fee applies.
Damaged or defective on arrival — fully covered. Every shipment is freight-insured end to end, so anything that arrives damaged is replaced or refunded at no cost — you're never on the hook for transit damage.
