Description
An 80mm hollow steel ball, a light, rounded finial for fence posts, play area posts and planters. This sphere is 80mm across, about the size of an orange, made from two pressed mild steel halves welded together with the seam ground back. The wall is about 2mm, so each ball weighs only about 0.31 kg, around a seventh of a solid 80mm ball. It has no hole; weld it onto a cap plate. The price shown is for one sphere, with a minimum order of 5.
Why choose this sphere
A rounded, safe top. A ball finial removes sharp post ends, ideal on play area, school and park fence posts where children are about.
Light on long runs. At about 0.31 kg it adds little weight to fence posts and planters, and is easy to lift and tack at height.
Smooth, round finish. The two halves are welded and the seam ground, so it paints up as a clean ball in any colour.
Good value. The same 80mm look as a solid ball at a fraction of the weight and price.
Where it is used
Play area, school and park fence posts, garden and front boundary fence posts, steel planter corners, gate posts on light gates, and garden structures and decorative frames.

Fitting and care
Weld a cap plate on box section posts and grind it clean. Sit the ball centred on the plate, tack it in three places and weld round in short runs, keeping the heat down on the thin wall. If the ball will be hot-dip galvanised, drill a small vent hole underneath first so trapped air can escape safely.
Degrease, then prime with a zinc-rich or metal primer before painting. Hot-dip galvanising before powder coating gives the longest life outdoors.
Frequently asked questions
Is the price for one sphere?
Yes, it is for one 80mm hollow sphere, with a minimum order of 5.
Is it solid or hollow?
Hollow. It is two pressed halves welded together, with a wall about 2mm thick.
Can I see the join?
The seam is ground back, leaving a smooth, slightly brighter band. Paint covers it completely.
Does it have a hole?
No. It is a plain ball that you weld to a cap plate.
Is it painted?
No. It is raw steel and will rust if left bare outdoors, so prime and paint it, or galvanise it, once it is welded on.
