Anyone specifying custom span marquee tents will find that the width is engineered to a project brief rather than pulled from a fixed catalogue. A made to order frame can carry a span between standard sizes when the floor plan demands it.
That flexibility helps awkward sites and unusual footprints, or venues where a column free width changes how the space is used. The rest of this page covers what is realistic and what to check before ordering.
What widths can custom span marquee tents cover?
When buyers ask about custom span marquee tents, the honest answer is that the width is not unlimited. Clear span systems use standard eave heights and bay depths, and the frame is calculated for a target span with a named wind and snow class.
A width outside the usual range is reached by adjusting the aluminium profile, the bay count, or the ridge design. A standard module such as the 30m clear span structure shows what a wide column free hall looks like.
How a non standard width is engineered
Engineering a made to order span starts with the load case. Ground conditions, wind exposure, and snow expectations feed the structural calculation, and the aluminium frame is then specified to meet that case with a margin. Exact profile dimensions are a manufacturer decision, not a buyer choice.
What you control is the bay arrangement. A structure is extended by adding bays or widened by combining spans, which is why a 20m wide marquee hall ships as repeatable modules. The 12m clear span marquee is one such module that can be joined to reach an odd total width.
Where custom span structures work best
The clearest wins are fixed footprints, such as a courtyard or a quayside. A bespoke width lets the marquee fill the space instead of leaving gaps at the edges.
Indoor sports and exhibition halls also benefit, because a wider span removes the break caused by an interior pole. A 15m span event marquee shows the open floor a custom width is meant to protect.
Site and engineering checks before you order
Before a custom span is agreed the site must be read properly. Level ground, delivery access, and a clear run for ballast or anchoring all shape what can be built, and a width that looks fine on paper can be hard to anchor on loose or sloped ground.
Permits are the other variable. Temporary structure rules differ by region, and a wider or taller build can move into a different approval class, so planning the engineering class early keeps lead time realistic.
Frequently Asked Questions
How much does a custom span marquee tent cost compared with a standard one?
A made to order width usually costs more because the frame is calculated and parts may be less standardised. The premium is modest against the value of removing an interior support, but it grows with how far the span departs from the usual range.
How long does a custom span structure take to deliver?
Lead time stretches with the amount of engineering and any non standard parts. A small step in width may add only a few weeks, while a new profile can take a full production cycle, so the brief should be fixed early.
Can a custom span marquee be reconfigured later?
Often yes, because the structure is modular. A future project can reuse bays or extend the span, which is the same principle shown by a 9m clear span marquee delivered as repeatable bays. The original engineering class still sets the limit.
