The 100 TFC 90 degree corner post lets a Canberra retaining wall turn a right angle in one post: two hot-dip galvanised 100 TFC channels welded together so sleepers from both wall directions seat fully at the corner. Without it, corners need two separate posts set close together, which looks clumsy and complicates concreting. Lengths run from 600mm to 3000mm in 200mm steps, from $48.
It belongs to the 100 series in our ACT steel post range, matched to 75 and 80mm sleepers in lower garden walls. The straight-run posts either side of the corner are the 100 TFC channel and 100 UC 14 H beam; for corners that are not square, see the 45 degree corner post.
What length corner post do I need?
Same rule as straight posts: post length is roughly wall height plus the embedment in the concrete footing, commonly around a third of the post in the ground for low walls, per your engineering. Corners take load from two directions, so follow the certified design, which ACT approvals typically require.
Can you make custom corner angles?
Yes. Non-standard angles are fabricated to order, quoted from the angle on your plan. Send the site plan with your quote request.
How is it delivered to Canberra?
ACT steel is supplied through the NSW network with freight into Canberra; lead time is confirmed at quote.
