Description
A 100mm hollow steel ball, the lightweight way to put a big ball finial on a pier, post or chain post. This sphere is 100mm across, about the size of a large orange, made from two pressed mild steel halves welded together with the seam ground back, leaving a smooth band round the middle. The wall is about 2mm, so it weighs only about 0.44 kg, roughly a ninth of a solid 100mm 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
Big look, little weight. At about 0.44 kg it gives the same 100mm ball as a solid sphere at a fraction of the weight and price, ideal on tall posts and lighter structures.
Easy to lift and weld. It is light enough to hold in one hand while you tack it, even at the top of a ladder.
Smooth, round finish. The halves are welded and the seam ground, so it paints up as a clean ball.
Rounded and safe. A ball top has no point to catch hands or clothing.
Where it is used
Brick and stone pier finials on base plates, chain and barrier posts, gate posts, bollards, garden and landscape features, and decorative work where a solid ball would be too heavy.
Specifications
| What you get | One sphere, minimum order 5 |

| Diameter | 100mm |
| Construction | Two pressed halves welded, seam ground, hollow |
| Wall thickness | About 2mm |
| Material | Mild steel |
| Finish | Raw, unpainted |
| Weight | About 0.44 kg each |

The wall thickness is worked out from the weight and rounded, so allow a little either way.
Which post does it suit?
| What you are topping | How the 100mm ball looks and fits |
|---|---|
| 75mm to 100mm post or chain post | A balanced finial, weld a cap plate on first |
| Brick pier up to 225mm square | Weld to a small base plate and fix the plate with resin anchors |
| 50mm to 60mm post | A bold, top-heavy look, weld a cap plate first |
| Large stone pier | Looks small, weld two 206mm hemispheres into a bigger ball |
Is this the right sphere?
| You want | Choose |
|---|---|
| A light, hollow 100mm ball | This sphere |
| A heavy solid 100mm ball | 100mm solid sphere |
| A smaller hollow ball | 80mm hollow sphere |
| A 100mm half ball dome | 100mm hollow hemisphere |
| A much bigger dome or ball | 206mm hollow hemisphere |
| Every sphere and hemisphere | All spheres and hemispheres |
Fitting and care
Weld a cap plate on the post, or cut a base plate for a pier, 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 100mm 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 round the middle. Paint covers it completely.
Does it have a hole?
No. It is a plain ball that you weld to a cap or base 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.
