Heavy-Duty Flat Top Steel Post Caps – Protection for Every Post Size
Protect your fence and deck posts with the ultimate in American-made durability. Unlike thin plastic or flimsy aluminum caps that crack over time, our Flat Top Steel Post Caps are hand-welded from thick, structural steel to provide a lifetime of protection and a clean, modern aesthetic for your outdoor space.
Custom Fit for Every Project We understand that not all "4x4s" are created equal. That is why we offer a full range of sizes to ensure a precision fit for both standard and rough-cut lumber:
Nominal Sizes (Standard Lumber): Fits standard posts found at most lumberyards.
Nominal 4x4 (Actual 3.5" x 3.5")
Nominal 4x6 (Actual 3.5" x 5.5")
Nominal 6x6 (Actual 5.5" x 5.5")
True Sizes (Rough-Cut/Hardwood): For the builder using full-dimension timber.
True 4x4 (Actual 4" x 4")
True 5x5 (Actual 5" x 5")
True 6x6 (Actual 6" x 6")
Custom sizes are available upon request—if you don't see your size, just ask!
Why Choose Madison Iron and Wood?
Veteran-Owned Quality: Every cap is hand-welded and inspected in our Madison, Indiana shop.
Superior Finish: Finished in a high-quality, baked-on powder coat with UV inhibitors to prevent the "chalking" or fading common with cheap paints.
Easy Installation: Each cap comes pre-drilled on two sides with matching powder-coated screws included for a seamless look.
Optional Zinc Primer: For maximum rust protection, we offer an optional zinc-rich primer—a "sacrificial shield" that prevents corrosion even if the finish is scratched.
Technical Specifications:
Material: Heavy-Duty American Steel.
Color Options: Available in Antique Copper, Semi-Gloss Black, White, and 11+ other premium finishes.
Origin: Made in the USA.

Just newly landscaped and fenced a new property, still a work in progress but my landscaper suggested adding fence post caps and so I did a random internet search which led me to Madison. So glad I did. I think it elevated my new cedar & hog wire fence. These are quality caps. You may not be able to see from the photo, but on the very back gate, I installed the red dog bone caps which are adorable...this area is technically my dog run so added those for fun.
We love the design and build quality. Very well made. Could not be Happier. If you are on the fence about buying one just do it. These will last forever.
Great product and fitment was perfect exactly what I wanted. I will be ordering more things. I would also like o add the whole process was seamless from ordering to shipping.
Duck came and I was excited. I was surprised when it didn't just fit from the get go. But I was made aware of the reason for this. I made the adjustments necessary and got it to fit nicely. It caps off my Oregon Ducks themed "bird feeder pole!"
Hope the pictures came through. I christened your duck with a yellow "O."
Thank you for your metal Duck topper for my 4x4 post. Go Ducks 🦆!!
Very high quality product that fit on my 4x4's perfectly. The order was shipped promptly and arrived long before promised. Overall, this was a great experience and I would purchase from this company again.
I purchased 10 different post caps and 21 total. They all came in perfect condition-well wrapped and not a scratch on them. Installed them all easily following the video instructions. They have only been up 2 hours and I received several compliments. Would highly recommend them to anyone.
PS. I appreciate the extra screws you sent since I lost one in the bushes!
The tolerance on a post is sloppy. The tolerance on these caps is very tight. Get yourself a sharp chisel. You may need to shave some wood. They look good. I am curious to see how they wear over the course of years with exposure to the elements.
Fantastic company. Love love love my fish rope rings (8) and the corner bracket works great for my deck netting. Can’t wait until my post caps come in. Unfortunately I didn’t order them at the same time. But delivery was quick Very highly recommend this company
I was looking for a way to dress up the post that supports the outlet for my pond pump, and your post cap with the dragonfly seemed perfect for my pond.
Items came very well packaged and protected. Arrived in perfect condition. They are as described and a good tight fit to the post. Very well made and not flimsy.
