Quantity, destination port and your contact details are enough for us to price it. Tell us the pole height or road class if you have them.
Ring Crown high mast lights are specified where a large area has to be lit from a single point — stadiums, ports, freight yards, highways and industrial sites. This pole carries a Ring Crown crown frame with 8 floodlights, so the whole area is covered from one foundation.
The pole is delivered hot-dip galvanised with the base plate welded on, the anchor bolts and the foundation drawing. The crown frame is drilled to match the floodlight brackets, and the pole door gives access to the wiring and the earth terminal.

How to choose the head count
The ring crown carries the floodlights on a circular platform at the top of the mast, aimed outward. Four head counts are available — 4, 6, 8 and 10 — on the same mast family. Shaft type (sectional or tapered) and whether a ladder is fitted are options on this page, not separate products, which is why they are not listed as models.
| Heads | What it covers | Where it is usually specified | Watch |
|---|---|---|---|
| 4 | The four quadrants of a contained area, aimed outward from a central mast | Small yards, car parks, loading areas | Least steel in the crown — cheapest way into a high mast |
| 6 | Six directions, closer spacing at the crown — smoother overlap at the perimeter | Industrial yards, logistics compounds | The most common configuration; a good default for a first enquiry |
| 8 | Wider coverage from the same mast height, with more overlap between beams | Large storage yards, port aprons | Wind area at the crown grows — mast section follows |
| 10 | Dense ring, maximum evenness at the outer edge of the lit area | Stadium surrounds, large transport hubs | Heaviest crown in the family; platform and lifting must match |
Adding heads narrows the gap between beams but does not extend the reach. If the area is larger than roughly 1.5 times the mast height in radius, the answer is a taller mast or a second mast, not more heads.
What decides the mast, not the head count
The crown is a wind-loaded disc at the worst possible place — the top of a 15–30 m cantilever. Three numbers drive the design: the total head weight, the projected wind area of the loaded crown, and the design wind speed for the site. A 4-head crown on a 30 m mast in an exposed location can demand more steel than a 10-head crown at 15 m in a sheltered one.
The mast is hot-dip galvanised as standard, in Q235 or Q355, with the base plate, door, cable entry and anchor bolts supplied against a foundation drawing. Because the foundation is designed to the actual crown load, the head count and the luminaire weight have to be fixed before the drawing is issued — not after the concrete is poured.
Ladder or no ladder
A fixed ladder is a maintenance decision. Without one, the crown is reached by a lifting carriage or a working platform; with one, the mast becomes a climbing structure and the specification changes (safety cage, rest platforms, fall arrest). If the project has no maintenance-at-height capability, say so early — it moves the specification to a lifting system rather than a ladder.
What to send with the enquiry
- Mast height and the radius of the area to be lit.
- Luminaire type, weight and beam angle — the crown is designed around them.
- Design wind speed, or the site location so it can be looked up.
- Whether access will be by ladder, lifting carriage or platform.
Crown types compared
The crown frame is welded to the pole top before galvanising, so the number of floodlights is fixed at order and cannot be increased on site. The table below compares the crown types we build; the row in bold is the range on this page.
| Crown frame | Floodlights | Access | Mounting note |
|---|---|---|---|
| Triangular | 3–9 | Fixed | Three faces at 120°; each added floodlight lengthens its arm |
| Ring Crown | 4–10 | Fixed, or ladder-access | Heads on a circular ring; the most common choice for yards and terminals |
| Double Ring | 12 | Fixed | Two concentric rings; more heads without lengthening a single arm |
| Single Side | 4–8 | Fixed | All heads on one side; used where the mast stands at the edge of the lit area |
| Hexagonal | 6–18 | Fixed | Six faces; carries the highest head count of the fixed crowns |
| Double Tier | 8–16 | Fixed | Two levels; the lower tier lights the base of the mast |
| Stadium Matrix | 6–12 | Fixed | Rectangular matrix frame aimed at a pitch or arena |
| Lifting Ring | 8–16 | Internal lifting device | Crown lowered to ground level for maintenance without a platform |
All crown types share the same mast specification: round conical section, Q235 or Q355 steel, hot-dip galvanised, 15–30 m standard heights, supplied with base plate, anchor bolts, earthing terminal and foundation drawing. Head counts outside the ranges shown are built to the project drawing.
