How Much Weight
Can A Modular
Stand Actually Hold?
Most display suppliers ask you to take structural performance on trust. In 2022 we sent the T3 system to a university engineering lab and had it loaded until it failed — more than twenty tests, each repeated three times. This page publishes what came back, including the numbers that are less flattering.

It Depends On The Configuration,Not On The System.
A T3 double frame carried a recommended safe distributed load of 1,200 kg at a 735 mm span. The same double frame carried 40 kg as a line load once the span was stretched to 1,225 mm. That is a thirty-fold difference in the same components. Anyone who answers “how much can it hold?” with a single number is guessing — the honest answer depends on span, on how the load is applied, and on what the structure is standing on.
Below are the headline figures from the University of West London programme. Every one is a recommended safe working load, set deliberately below the point at which the structure actually failed — in several tests the measured failure load was roughly double the figure we publish. They apply to the configurations tested and are a guide for specification, not a substitute for engineering advice on your particular build.

Two Findings That ChangeHow You Specify A Stand.
These are the parts worth knowing even if you never read the report. Neither is obvious, and neither is something the industry generally publishes.
Span matters far more than people assume
Under line load, a double frame at a 735 mm span took 300 kg. At 980 mm it still took 300 kg. At 1,225 mm it took 40 kg. The components are identical; only the distance between supports changed.
In practice this is why a shelf run, a fascia or a counter top should be broken up with an intermediate upright rather than spanned in one go — and why a design that looks fine on screen can be well outside sensible loading. Where an unsupported span is unavoidable, rigidisers (SCLMPX) reduce stress at the profile-to-connector joint.
On flooring, the feet are the limit — not the frame
The same floor structure was tested three ways. Sitting directly on the ground it carried 2,000 kg. On nutsert M8 feet, 600 kg. On static M8 feet, 300 kg. In each of the raised tests, failure initiated in the feet rather than anywhere in the aluminium.
So a raised floor that has to carry a vehicle, a heavy exhibit or a crowd is a question about foot specification and ground contact, not about the framework. Tell us the load at briefing stage and we specify accordingly.
Every Test,Including The Unflattering Ones.
Dimensions are given as length × height × width in millimetres, matching the report. Figures are recommended safe working loads for the configuration tested.
Frame structures
| Test | Load type | Configuration | L × H × W (mm) | Safe load |
|---|---|---|---|---|
| 1 | Line load | Double frame | 367.5 × 735 × 612 | 300 kg |
| 2 | Line load | Double frame | 490 × 980 × 980 | 300 kg |
| 3 | Line load | Double frame | 1225 × 1225 × 612 | 40 kg |
| 4 | Eccentric point load | Double frame | 367.5 × 735 × 612 | 200 kg |
| 5 | Eccentric point load | Double frame | 490 × 980 × 980 | 150 kg |
| 6 | Eccentric point load | Double frame | 612 × 1225 × 1225 | 150 kg |
| 7 | Distributed load | Double frame | 367.5 × 735 × 612 | 1,200 kg |
| 8 | Distributed load | Double frame | 490 × 980 × 980 | 1,200 kg |
| 9 | Distributed load | Double frame | 612 × 1225 × 1225 | 500 kg |
| 10 | Distributed load | Triple frame | 367.5 × 735 × 400 | 1,500 kg |
| 11 | Distributed load | Triple frame | 490 × 980 × 980 | 1,500 kg |
| 12 | Distributed load | Triple frame | 612 × 1225 × 1225 | 800 kg |
| 13 | Line load | Triple frame | 500 × 735 × 400 | 800 kg |
| 14 | Distributed load | Double frame | 612 × 612 × 212 | 400 kg |
Test 13 is valid only with supports and horizontal members fixed to the ground. Test 14 requires the frame placed directly on the ground.
Flooring
| Test | Configuration | Safe load | Where it failed first |
|---|---|---|---|
| 16 | Floor, no feet (directly on ground) | 2,000 kg | Joints |
| 18 | Floor on nutsert M8 feet | 600 kg | Nutsert feet |
| 17 | Floor on static M8 feet | 300 kg | Feet |
| 19 | Eccentric line load, nutsert M8 feet — LED monitors | 153 kg | Nutsert members |
| 20 | Eccentric line load, static M8 feet | 51 kg | Static M8 feet |
Tests 19 and 20 were run with lower members ballasted with 50 kg sandbags to prevent rotation — relevant if you are cantilevering a screen off a raised floor.
Connectors
| Test | Connector | Maximum pull-out load |
|---|---|---|
| 15 | M5 threaded fitting | 50 kg (0.5 kN) |
| 15 | M8 threaded fitting | 100 kg (1 kN) |
Pull-out figures govern anything suspended from or rigged to the structure. A reinforced M8 fitting is available where a higher margin is needed.
Where The NumbersActually Get Used.
Load data only matters when something has to be carried. These are the T3 products where the testing directly informs what we specify.
Raised & Illuminated Flooring
T3 flooring panels use the same profiles and twist-lock connectors as the rest of the system, raised on adjustable feet to level on any surface. Because capacity is set by the feet, specify the foot to the load: directly grounded for the heaviest exhibits, nutsert feet where the floor must be raised and still carry weight, static feet for lighter builds. Combined with T3 Wandlight the floor can be lit from beneath.
Flooring brochure →Hanging Banners & Rigged Structures
Suspended signage, overhead banners and circular hanging rings are all governed by connector pull-out rather than profile strength. Lightweight Ultralite profiles reduce the load being asked of each fixing. Rigging into venue steel is specified per venue and per build — send us the rigging spec with your brief and we will work to it.
Modular exhibition stands →Screens, Monitors & LED Tiles
A dedicated eccentric line load test was run for LED monitor installations, because a screen hung off one face loads a frame very differently from weight sitting on top of it. T3 offers monitor support hooks (MSH), full VESA brackets and an LED arm bracket for tile panels, and the internal SEG corner lets a screen sit flush in the surface. Used by Lancôme and Kiehl’s for 86″ screens.
AV accessories datasheet →Shelving, Counters & Product Display
Finding one applies most directly here. Shelf brackets come in 150, 200, 250 and 300 mm, with fixed, adjustable and twist-in supports. For heavy product — bottles, hardware, samples — break long runs with an intermediate upright rather than spanning the full bay, and expect us to ask what is going on the shelf before we quote it.
Counters & podiums →Towers & Tall Structures
T3 towers are raised in sections up to six metres. Above modest heights the governing factors stop being static load and become bracing, ballast and footprint, which is why tall builds are specified individually rather than from a table. Outdoor towers additionally require clamps and counterweights sized for the site.
Island exhibition stands →Rigidisers & Reinforced Fittings
Where a design demands a longer span or a heavier load than standard configuration allows, support clamps (SCLMPX) reduce stress at the profile-to-connector joint, and a reinforced M8 threaded fitting raises the margin at the fixing. These are the components that turn a marginal design into a compliant one.
T3 Frame specifications →Published Honestly,Which Means With Limits.
Every figure on this page is a recommended safe working load, not a failure load. The report records both, and the gap is deliberate: in the flooring test the structure was still carrying load at around 40 kN when the recommendation was set at 20 kN. That margin exists because exhibition halls are not laboratories — stands get leaned on, knocked by forklifts, loaded unevenly and built by tired people at two in the morning.
Please read this before applying anything above
These figures relate to the specific configurations tested in June 2022 and are published as guidance for specification. They are not an engineering certificate for your build, and they should not be used to justify a load on a structure that differs from the ones described.
Anything involving rigging, suspended loads, raised floors carrying vehicles or crowds, tall or outdoor structures, or public-facing loading should be specified individually. We provide project-specific engineering data with your design — ask for it at brief stage rather than after the stand is built.
If your venue, organiser or insurer requires structural documentation, tell us early and we will supply what they need.
