The two ways to stand a rental wall
Rental LED goes up either as a ground stack, built up from the floor on a base and stacking frames, or flown, suspended from a truss or roof. The choice shapes transport, labour, and the look of the event.
Ground stacking is simple and needs no overhead rigging, which suits rooms with low ceilings or no rig points. Flying clears the floor and lets the wall sit higher and deeper in the sightlines.
Neither is universally better. The right call follows the venue, the sightlines, and what the crew can safely rig on the day.
Ground stack trade-offs
Ground stacks are fast to build and easy to access for service, because the whole wall sits within reach from the floor. They need floor space and a flat, load-bearing base.
Height is limited by stability, so very tall walls favour flying. A leaning or over-tall stack is a safety risk, and the base must suit the surface, from concrete to temporary flooring.
Stacks work well for smaller shows, atriums, and venues where rigging is impractical. They keep the crew on the ground, which lowers both cost and risk.
Flown trade-offs
Flown walls free the floor and reach sightlines a stack cannot, which is why stages and large rooms use them. They depend on rated rigging points, certified truss, and a competent rigging plan.
Access for service is harder once the wall is in the air, so flown builds favour front-service panels and a clean pre-show check, because fixing a fault mid-show is disruptive.
Flying adds weight-loading maths and permit considerations. The ceiling or roof must carry the loaded wall, and that limit is non-negotiable.
Transport and labour
Ground stacks often ship as fewer, simpler frames, which can lower truck space and build time. Flying needs truss, motors or spansets, and more specialised crew.
Labour skill drives cost. A stack a general crew can build differs from a flown wall that needs riggers and a signed plan, and that difference shows in both price and schedule.
Choose with the whole event in mind. A wall that is cheap to fly but needs riggers you do not have is not the cheaper option on the day.
Choosing for the event
Match the method to the room and the programme. Low ceiling and no rig points point to a stack; a raised stage and long sightlines point to flying.
Confirm the venue limits before quoting, because a supposed flown build blocked by a weak roof becomes a stack anyway, at the cost of re-planning.
Document the method in the show file with the rigging or base plan, so the next build starts from a known, safe configuration and not from a guess.
A flown plan with no rigging points
An event quoted flown, but the hall had no rated truss points. Converting to ground stack on site cost a day and re-rigging fees; checking first would have avoided it.
Stack blocked the front row
A ground stack rose into the sightline of the front audience. Lowering it lost impact; the content was re-cut for a shorter wall. Sightlines should drive the choice, not the reverse.
Applying this on site: ground stack vs flown
- Read the venue and sightlines first Note floor space, ceiling height and where the audience stands. Stacks need floor and low sightline obstructions; flown needs rigging points and clear overhead.
- Confirm weight and rigging limits For flown walls, check truss rating, point loads and crew certification. Quoting before that risks a forced re-plan on site.
- Plan transport and labour Ground stacks move as more, smaller loads and need fewer specialists; flown needs riggers and lift access. The choice changes the truck plan and the crew.
- Decide service access for the event Stacks are reached from the front or rear at floor level; flown panels need lift or climb access. Match it to how fast a fault must be fixed mid-show.
Ground stack vs flown: myths and reality
“Flown is always more impressive.” — Flown reaches height and clears floors, but a well-built stack at the right height serves many events and is simpler to service. Impact follows the brief, not the rigging method.
“Ground stack needs no planning.” — Stacks still need floor space, weight distribution and sightline checks. Treating them as plug-and-play leads to blocked views and unstable bases.
The decision in one line: ground stack vs flown
Pick ground stack or flown rental LED from the venue and sightlines. Stacks are simple and serviceable but need floor; flown reaches height but needs rigging and crew. Confirm limits before quoting to avoid a forced re-plan.
