Fence Posts and Rails in Lubbock, Amarillo and Midland
Posts are the part of a fence you stop seeing once it’s built, and the part that decides whether it’s still standing straight after a few West Texas springs. All-State sells fence posts and rails at all three Fence Supply Centers — Lubbock, Amarillo & Canyon, and Midland & Odessa — with no minimum order. We stock Schedule 40 steel posts in every size, bought by the truckload months ahead so we don’t run out, along with lighter posts and cedar rails. They’re the same posts and rails our crews set every week.
Steel fence posts we stock
| Post (all 2⅜" outside diameter) | Wall | Best for |
|---|---|---|
| Schedule 40 | Heaviest available | Every wood fence our crews build; required for 7- and 8-foot fences and gate posts |
| .095 | Medium | 6-foot fences in town, out of the wind |
| .065 | Light | Budget do-it-yourself fences |
| .047 and .055 | Lightest | Chain link only, never a wood fence |
Steel and lumber prices change with almost every truckload, so posts and rails are priced at the counter on the day you buy. Contractors, schools, government buyers and volume orders pay less.
Which steel fence post do I need?
Every steel post we sell is 2⅜ inches across the outside, so they all look the same in the rack. The wall thickness is what makes one strong and another weak, and in West Texas the post is the foundation of the fence. Schedule 40 is the heaviest post available, and it’s the post our crews set on every wood fence. On a 6-foot fence in town, out of the wind, we’ll set the next-heaviest .095 post for a customer who wants to save money. The counter also sells a lighter .065 post for do-it-yourselfers, and even thinner .047 and .055 posts made for chain link, which look exactly like Schedule 40 from the outside but have walls about as thin as a soda can. Those should never hold up a wood fence.
Three things decide which one you need:
- Height. A taller fence is a bigger sail. Every foot of height adds leverage at the base of the post.
- Gates. A gate post carries the gate’s weight on one side every day. It should always be heavier than the line posts around it.
- Exposure. An open lot facing the prevailing wind loads posts harder than a fence sheltered by houses and trees.
A 7- or 8-foot fence needs Schedule 40 in a 9- or 10-foot length, plus another foot for a capped fence. Tell the counter the height, the gates and where the fence sits, and they’ll match the post to the job.
How far apart should fence posts be, and how deep?
We set posts on 8-foot centers, at least 3 feet deep and fully set in concrete, and 4 feet deep on an 8-foot fence. Some installers stop at 2 feet. The top 2 feet of West Texas ground is softer than the foot below it, where the hole reaches harder dirt and clay, so that last foot is what keeps a fence standing.
Whatever the spacing, the principle is the same: the hole has to reach full depth and full width so the concrete can do its job. A shallow hole backfilled with dirt is how a fence starts leaning after the first hard wind.
What if there’s rock under my yard?
In parts of West Texas there’s a layer of rock just under the dirt, and it changes how posts go in. In the Permian Basin, our crews run CAT 299D skid steers with augers built for caliche and rock, so post holes come out at full depth instead of stopping where the digging got hard. If you’re setting your own posts and hit rock, stop and call the counter before you shorten the hole. It rarely comes up in Lubbock and Canyon, and when it does, the crews use the same approach: a skid steer auger or a jackhammer to get through the rock.
Rails
Rails carry the pickets between posts. On a wood privacy fence, the number of rails per section and how they attach to steel posts decide whether the pickets stay flat or start to wave. We use three rails per section on a 6-foot fence and recommend cedar.
The rails attach to steel posts with WPA-O wood-to-steel brackets, which our crews install and every Fence Supply Center sells. We don’t sell treated lumber.

Questions
How much is a steel fence post?
Steel prices change almost every week, so call the nearest Fence Supply Center for today’s price. A Schedule 40 post costs more than a lighter post, and it’s the one we recommend.
What does post schedule or gauge mean?
It’s the steel’s wall thickness. A heavier-wall post resists bending better and costs more; height, gates and wind exposure decide which you need.
How deep should fence posts be set?
We set posts at least 3 feet deep, fully set in concrete, and 4 feet deep on an 8-foot fence, on 8-foot centers.
Should a gate post be heavier than a line post?
Yes. It carries the gate’s weight every day.
Do you sell fence rails?
Yes, with no minimum order. Lumber prices change with almost every rail car, so call for today’s price.
A note on sizes: lumber is sold by its nominal size. A picket sold as 1 inch measures closer to ⅝ inch, and a rail sold as a 2×4 measures about 3⅝ inches across its 4-inch side.
