End Caps & Post Covers for Retaining Walls

The finishing details on a retaining wall matter more than most people realise. End caps and post covers protect exposed steel post tops from water ingress, rust, and debris — and give your wall a clean, professional finish that holds up over time.

A wall built without end caps is a wall that will start rusting from the top down. It's a small investment that protects a much larger one.

Why End Caps Matter

Open steel post tops collect water. Water sits in the post, accelerates corrosion from the inside out, and over time compromises the structural integrity of the post — even on hot-dip galvanised steel. End caps seal the top of the post, preventing water entry and extending the life of your wall system significantly.

They also give the wall a finished, intentional look rather than the raw cut-steel appearance of an uncapped post.

What's Available

Post end caps — fit over the top of H-beam and C-channel steel posts to seal and protect
