Gatepost reinforcing question

[Smouser]

I just had a look at my order history. My post is 100x100x5mm and so far they are holding up just fine.

Okay, I’ve bitten the bullet and bought a piece of 100x100x6.

Does anyone in the Essex area want to buy and collect (2 pieces) of 100x100x4 that's now going spare!

Where are you based?

brad what is the deflection of the i beam girder or h frame steel girder

considering theyve been used for years as gate posts on many things even lasted the test of time just by concreted in and set in place without all of the framing underneath

i know there great in horizontal strength and vertical strength

Brad,
I’m on the outskirts of Maldon, not far off the A12.
I have a total of 7.5m, unfortunately I cut it into two pieces. 1 piece is 2.3m and the other 5.2m.

Impossible to say without knowing the size

ive seen often where 6x 10s or 6x12s are used but there on long gate openers

i agree with most of the advice above & would like to add there is no substitute for depth in the ground.
