Description
A solid 90mm forged steel ball, a heavy finial for wall piers, gate posts and bollards. This sphere is 90mm across, about the size of a large apple, forged from mild steel and solid all the way through, with a lightly textured forged surface and no hole. Weld it to a cap plate or base plate to finish a pier, post or bollard. Each ball weighs about 2.94 kg. The price shown is for one sphere.

Why choose this sphere
Solid and weighty. At nearly 3 kg it has the feel of real forged iron, will not dent or fill with water, and stands up to knocks on a bollard or driveway post.
In proportion on 75mm to 100mm posts. A 90mm ball sits well on the most common gate post and bollard sizes, and on small brick piers when mounted on a base plate.
Rounded and safe. A ball top has no point to catch hands, clothing or car doors.
Easy to weld. Mild steel welds cleanly with MIG, TIG or stick, and being solid you can grind the weld smooth.
Where it is used
Brick and stone wall pier finials on base plates, gate posts, bollards and barrier posts, staircase newels, garden and landscape features, and sculpture and counterweights.

Fitting and care
Weld a cap plate on box or tube posts, or cut a round base plate for a pier, and grind it clean. Sit the ball on a ring of bar or a large nut so it cannot roll, check it is centred from the front and the side, tack it in three places and weld round. A ball this heavy needs a full weld, not a few tacks.
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 90mm solid sphere.
Is it solid or hollow?
Solid forged steel all the way through, about 2.94 kg. Hollow spheres are also available if you need less weight.
Does it have a hole?
No. It is a plain ball that you weld to a cap or base plate.
Is it perfectly smooth?
No. It has a forged surface with light texture. Paint hides most of it, or you can flap-disc it smoother before painting.
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.
