LED wall weight and structure.
What the wall, the frame and the building must carry.
The screen is only half of an LED wall project. The wall or steel behind it has to carry the load safely for years, give technicians access, and on outdoor screens stand up to wind and rain. Here are planning weights and the structure questions to settle before you order.
Planning weights.
| Wall | Area | Die-cast aluminium (≈30 kg/m²) | Steel, front service (≈42 kg/m²) | Steel, rear service (≈45 kg/m²) |
|---|---|---|---|---|
| 8 × 4 ft | 3.0 m² | 90 kg | 120 kg | 130 kg |
| 10 × 6 ft | 5.6 m² | 170 kg | 230 kg | 250 kg |
| 12 × 6 ft | 6.7 m² | 200 kg | 280 kg | 300 kg |
| 16 × 9 ft | 13.4 m² | 400 kg | 560 kg | 600 kg |
| 20 × 10 ft | 18.6 m² | 560 kg | 780 kg | 840 kg |
Screen only. Add the mounting frame, which depends on the site. Your quotation should state the exact screen weight for the cabinets used.
Which walls can carry it.
Usually fine for a front-service wall on a steel frame with the right anchors, checked at the survey.
Not load-bearing. The frame must go to the slab or structure behind, or stand on the floor.
Check the condition before adding load, especially for rooftop and facade screens.
Where the wall cannot take load, a steel frame on the floor carries the screen; useful in rented spaces.
Front or rear service.
A front-service wall is opened from the front, so it can sit flat against the wall and saves floor space indoors. A rear-service wall needs a walkway behind it, which suits hoardings and big outdoor screens. Compared in detail in front vs rear service.
Outdoor structures.
An outdoor screen is a sail in the wind. The steel structure has to be designed for the screen weight plus wind load, fixed to a proper foundation or the building frame, with a rain cover, a rear walkway on rear-service builds, and earthing. Have it checked by the installer or a structural engineer before ordering. See LED and digital hoardings.
Questions.
How heavy is an LED wall?
As a planning figure, die-cast aluminium cabinets weigh around 30 kg per square metre and steel cabinets around 42 to 45 kg per square metre, before the mounting structure. A 10 × 6 ft wall is about 5.6 square metres, so roughly 170 to 250 kg.
Can an LED wall be fixed to a brick or gypsum wall?
A solid concrete or brick wall can usually carry a front-service LED wall on a steel frame with the right anchors. Gypsum and dry walls cannot carry the load on their own; the frame must be fixed to the structure behind or stand on the floor.
What structure does an outdoor LED hoarding need?
A steel structure designed for the screen weight plus wind load, with proper foundations or building fixings, a rear walkway for rear-service screens, a rain cover and earthing. It should be checked by the installer or a structural engineer before ordering.
What is the difference between front and rear service for mounting?
A front-service wall is serviced from the front, so it can sit flat against a wall. A rear-service wall needs a gap or walkway behind it for technicians, which suits hoardings and large outdoor screens.
