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.
Triangular 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 triangular crown frame with 3, 6 or 9 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 triangular crown spreads the floodlights over three faces instead of a continuous ring, so the head count runs in multiples of three: one, two or three lamps per face. The layout is aimed at rectangular and irregularly shaped yards, where a ring puts light where it is not needed and leaves corners dark.
| Heads | Layout | Where it is usually specified | Watch |
|---|---|---|---|
| 3 | One lamp per face — three beams, three directions | Narrow yards, boundary lighting, small compounds | The lightest crown in the range; corners between beams stay dim |
| 6 | Two per face — each direction gets a near and a far throw | Rectangular industrial yards, warehouse aprons | The usual choice when the area is longer than it is wide |
| 9 | Three per face — densest triangular coverage | Large yards, port aprons, freight terminals | Heaviest crown of the three; platform design must match |
Because the faces are at 120 degrees, the aiming of each face can be set independently. That is the practical advantage over a ring: the three directions do not have to be lit equally, so a yard with a building on one side and open ground on the other can be lit to two different requirements from one mast.
What decides the mast
Height (15–30 m standard), total head weight, the projected wind area of the loaded crown and the design wind speed for the site. The triangular layout has a smaller projected area than a full ring carrying the same number of heads, so for a comparable coverage it can allow a lighter mast — but only if the site's wind speed is calculated, not assumed.
The mast is hot-dip galvanised as standard in Q235 or Q355, delivered with base plate, door, cable entry, anchor bolts and a foundation drawing matched to the actual crown load. Sectional or tapered shaft, and whether a base hoist or ladder is fitted, are options on this page rather than separate products.
What to send with the enquiry
- Mast height, and the dimensions of the area rather than just its radius.
- Which of the three directions carries the heavier lighting requirement.
- Luminaire type, weight and beam angle.
- Design wind speed, or the site location.
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.
