Description
A solid 150mm forged steel ball, the largest and heaviest finial in the range, for big gate piers and heavy bollards. This sphere is 150mm across, about the size of a small football, forged from mild steel and solid all the way through, with a lightly textured forged surface and no hole. Weld it to a base plate on a large pier or a cap plate on a heavy post or bollard. Each ball weighs about 13.15 kg. The price shown is for one sphere.
Why choose this sphere
The grand finish. At 150mm it is in proportion on large brick and stone piers at manor and estate entrances, where smaller balls look lost.
Solid and tough. Over 13 kg of forged steel will not dent, crack or fill with water, and shrugs off knocks from vehicles on a busy entrance bollard.
Rounded and safe. A ball top gives a heavy bollard or post a smooth, rounded finish with no sharp edges.
Easy to weld. Mild steel welds cleanly, and being solid you can grind the weld smooth.
Where it is used
Large brick and stone gate pier finials, manor, estate and hotel entrances, heavy bollards at business parks and car parks, landscape and garden features, and sculpture and counterweights.

Fitting and care
Cut a cap or base plate at least 120mm across from 6mm plate or thicker, and grind it clean. Sit the ball on a ring of bar so it cannot roll, check it is centred from the front and the side, then weld round with a full weld. On a pier, fix the base plate with four resin anchors and bed it on sealant to keep water out.
Degrease, then prime with a zinc-rich or metal primer before painting. Hot-dip galvanising before powder coating gives the longest life outdoors. It weighs over 13 kg, so lift it with care, and use two people when fitting it at height.
Frequently asked questions
Is the price for one sphere?
Yes, it is for one 150mm solid sphere.
Is it solid or hollow?
Solid forged steel all the way through, about 13.15 kg. For a lighter ball the same size, weld two 150mm hollow hemispheres together.
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.
