How is concerts scoped?

Against your guest count, venue and run of show. We size the design to the brief and quote it itemised, rather than selling a fixed package that may be larger or smaller than the room actually needs.

Do you provide structural load calculations?

Yes, on every build. We produce calculations covering the dead load of the structure, the live load of performers and crew, the suspended load from every department, and wind load outdoors. The point-load report per leg goes to the venue or your structural engineer for sign-off before load-in.

How much weight can be hung from a truss grid?

It depends entirely on truss type, span, support spacing and hoist capacity, which is why it is calculated rather than quoted from memory. The practical answer is that we publish a suspended-load budget at design stage and every department books their weight against it, so the grid is never discovered to be overloaded on the day.

What wind speed is safe for an outdoor roof?

There is no single number, because it depends on the structure, the banner area and the ballast scheme. What every outdoor roof must have is a documented wind management plan with staged thresholds — a speed at which banners are removed, a higher one at which the roof is lowered or the show stops — an anemometer on site and a named person empowered to act on it.

How high should the stage be?

Indoor seated audiences are well served at 0.6 to 0.9 metres. A standing audience more than fifteen metres deep needs 1.2 metres or more, and a large concert stage runs 1.8 to 2.4 metres. Going too low saves a little on deck and then costs far more in IMAG screens for the people who cannot see.

Can you build on grass, sand or uneven ground?

Yes, with an assessment first. Ground bearing capacity determines whether we use load-spreading base plates, a scaffold base, or a different anchoring approach. Soft and wet ground is the common cause of structures going out of plumb overnight, so we re-check level and plumb after the first night of any multi-day build.

Best Stage & Truss Fabrication Setup for Concerts

Key takeaway

The right stage & truss fabrication for concerts is sized to audience and venue shape rather than sold as a package. Expect layher & aluminium deck stages, a dedicated operator, and redundancy on anything whose failure would stop the show.

Why concerts need a designed system

Modular stages, ground support, roof systems and custom truss structures engineered with load calculations and certified rigging crews. Structure is the one department where getting it wrong is not an aesthetic problem. Every stage and truss build starts from a load case: the dead load of the structure itself, the live load of performers and crew, the suspended loads of lighting, audio and LED, and — outdoors — wind load on any banner, roof or solid surface. We specify from manufacturer load tables for the exact truss type and span, with chain hoists rated well above the working load and point loads calculated per leg. Decks are Layher or aluminium framed systems with a published uniform load rating, and a performance stage is typically designed for 500 kg per square metre of distributed live load.

Match the rig to the room

Scale	Guests	Recommended setup
Conference stage	200 – 600	10 m x 6 m deck at 0.6 m, front truss on two uprights, 1 t suspended load
Wedding stage	400 – 1,200	12 m x 8 m deck at 0.9 m with ramps, four uprights and a decor-integrated grid
Launch stage	1,000 – 3,000	16 m x 10 m deck at 1.2 m, ground support grid, 3 – 5 t suspended load
Concert stage	5,000 – 15,000	18 m x 12 m deck at 1.8 m, roof system, PA wings, 10 – 15 t suspended load
Festival main stage	20,000+	24 m x 16 m with 2.4 m deck, engineered roof, mother grid, ballast and wind plan

Honest alternatives

Ground support towers instead of flying from the venue structure
Our verdict
Ground support costs more and eats floor space, but it carries its own load to the floor and removes any dependence on a venue capacity you cannot verify. Where the venue has documented, engineered rigging points, flying is cheaper and cleaner.
Scaffold stage instead of a modular deck system
Our verdict
Scaffold is cheaper and infinitely adaptable, and for a long-run outdoor build on uneven ground it is often the sensible choice. Modular decks are faster, flatter, quieter underfoot and look finished without extra cladding.
A roof system instead of a tent or shamiana over the stage
Our verdict
A fabric structure is cheaper and keeps rain off people, but it will not carry lighting or audio load and its own wind behaviour is usually undocumented. If anything needs to hang above the stage, it needs an engineered roof.
