15m Span Event Marquee: A Clear-Floor Width for Mid-Size Events

A 15m span event marquee is the workhorse width for mid size hire fleets that need a clear floor without internal poles. The 15m clear span gives a column free hall that seats a banquet, hosts a trade stand, or covers a short span sports court.

What a 15m span event marquee covers on site

The 15m clear span is the width. Length is built in 5m bays, so a single module is 15x5m, and most event layouts run 15x20m, 15x30m or 15x40m. At 15x30m the floor is 450 sqm, enough for around 300 banquet seats.

A 15m span event marquee needs a clear 18 to 20m working width for the eaves and gutter, plus room for the forklift that lifts the aluminium beams.

Frame, span and bay construction

The structure is an aluminium frame with a PVC roof and wall set, and the clear span means no centre pole drops into the floor. Bay spacing is usually 5m, and each bay clicks onto the next, which is why a modular event marquee system scales from one unit to a long hall without reworking the frame.

Roof options run from a standard gable to a curved or polygon profile, and the wall set swaps between solid PVC, glass, and clear panels. The aluminium frame marquee structures stay light enough to move on a rental truck yet rated for the wind and snow load a touring season brings.

Where a 15m span marquee fits best

Sports and events use the 15m span for badminton and tennis courts, spectator sides, and warm up zones. A large marquee tent for trade exhibition also draws on the same frame when a show needs a quick build hall with full height branding.

Banquet and hospitality teams pick the width for its sightlines. At 15m the furthest guest sits under 8m from centre, so speech and stage read across the room. Clear span tents for large events scale the same bay logic up to 40m when the crowd grows.

Siting, ground and access

Ground decides the anchoring. On grass the frame takes steel stakes, and on hard standing it uses weight plates and water ballast, so the same clear span marquee goes from a park to a car park without a different kit list. A rapid install modular event marquee build of this size is a half day with a four person crew and a telehandler.

Access is the quiet risk. Delivery needs a vehicle that can reach the build line, not just a gate that looks open. Plan the route for the longest beam, check overhead cables, and confirm the surface will take the ballast before the truck is loaded.

Frequently Asked Questions

How many guests can a 15m span event marquee seat?
A 15x30m layout seats about 300 for a banquet with a dance floor, or near 450 in theatre rows. The 15m width keeps every seat within comfortable sight of the stage.

Can a 15m span event marquee be anchored on hard ground without stakes?
Yes. On concrete or tarmac it uses weight plates or water ballast instead of ground stakes, so it installs on car parks and plazas with no surface damage.

What wind and snow load does a 15m span event marquee carry?
A standard aluminium frame is rated for moderate wind and seasonal snow, with engineered options for exposed sites. Confirm the local rating with the supplier before a winter or coastal booking.
