A 45 degree corner post is two 100 series channels set at 135 degrees to each other, so sleepers from both wall directions seat into the one galvanised post with no cutting, packing or site welding. This is how you take a sleeper wall around an angled boundary or splay a wall away from a driveway and keep every sleeper fully seated. Lengths run from 600mm through 3000mm in 200mm steps, priced from $54.
Use these with 75 to 80mm sleepers on 100 series walls; the corner post is set in concrete like a standard post, with length chosen the same way (roughly double your retained height, per your engineering). They complete the 100 TFC family alongside the straight 100 TFC channel posts and the 90 degree corner version.
My corner is not exactly 45 degrees. What then?
Custom-angle corner posts can be quoted: measure the internal angle of the wall and we will have the post fabricated to the inverse angle and galvanised. Send the angle and post length with your quote request.
Are these strong enough for tall walls?
The 100 series is matched to 75 to 80mm sleepers and standard garden wall heights. Taller or engineered walls typically step up to 150 series posts; if you have an engineering schedule, send it through and we will quote the whole post list from it.
How do I get them in Sydney?
Delivery across NSW usually takes 5 to 10 business days, or pick up with the rest of your order from Wetherill Park by appointment (afternoons, before 3:30pm). Browse all NSW steel posts.
