Fix sagging metal post

Hi guys,

I cemented in a post around 500mm in to the ground and planted in around 100kg of cement. The posts are square and metal. The post isn't fixed to anything as it's on the boundary. We've got a metal fence on two hinges hanging off it. As soon as the post took the weight of the gate, the post started to sag from the first hinge up. At the very top, it sags in around 20-25mm.

Would it be worth pouring cement all the way to the top in a bid to strengthen the post? I'd obviously get the post level first so I'm not cementing a wonky post.

Any help appreciated thanks.

You'd probably be better off tying that post to the next one or bracing it with an angled post.

A picture of your gate would help.

Is the steel post bending or is it moving in the ground?

Hi,

Thanks for your responses.

I'll get a picture tomorrow as I won't be home for a while.

The post is bending, from the first hinge up. The concrete is fine.

Is there a reason why pouring concrete down the middle of the post won't work?

If the post is bending then filling it with concrete can help. And it's cheap and easy to try. But... I'm not sure if concrete will help enough. If the current post was carrying the load but you wanted a safety margin then I'd be more excited about the concrete. In your case I'd say the post is simply undersized and concrete may not be a long term solution, especially if the gate is operated frequently.

Thanks guys.

I think I'm going to try and pour the cement. I just had the bright idea to tap the post to get an idea of how far the post is filled up with cement. It sags about 100mm after where the cement has been filled up the post.

Thanks for everyone's input. I'll let you know if it appears to fix the issue.
