Inflatable Square Arches: Straight Legs and Flat Print Panels
A square arch replaces the curved span with straight legs and a flat crown. It exists for one reason: a design that has to hold a row of sponsor lockups, a straight baseline or a rectangular panel needs a surface that does not curve away underneath it.
A sponsor tier is a grid: a headline partner, then a row of equal-weight marks, often with agreed relative sizes written into the contract. A grid needs a flat surface. On a curved crown the outer marks in a row sit at a steeper angle than the middle one and photograph smaller, which is exactly the sort of thing a sponsorship manager notices.
The trade is in the silhouette and the structure. A square profile reads as a gateway rather than an arch, and the corners carry more stress than a continuous curve does, so they are reinforced and the reinforcement is shown on the drawing you approve.
The crown is a flat printed face, so type and sponsor rows sit on a straight baseline.
Straight legs give two more usable vertical panels than a curved profile does.
The corners are the structural detail: they are reinforced and shown on the production drawing.
Specification
What a quotation for this format is built from.
Sizes buyers usually order
An arch is sized by the opening it has to span. As planning references from delivered project types: grand openings and retail forecourts are commonly about 3–8 m wide × 3–5 m high, race and finish-line gantries clear opening 4–8 m wide × 3–5 m high, festival gateways 4–10 m wide × 3–6 m high, school and campus events 3–6 m wide × 3–4 m high, and team tunnels and sponsor gates 4–8 m wide × 3–5 m high.
Send the clear opening you need — the width and height that have to stay unobstructed — rather than an overall size. The legs sit outside that opening, so an arch built to clear six metres is wider than six metres on the ground, and that difference is what decides whether a vehicle, a timing gantry or a field of runners actually fits through.
The span, the legs and the ground it stands on
Three dimensions are quoted, not one: the clear opening, the overall footprint including the legs, and the height at the crown. A site that is measured only at the opening can turn out to have no room for the legs, which is the most common reason an arch has to be rebuilt at a smaller size.
The ground matters as much as the measurement. Grass, sand, tarmac, paving and an indoor floor each take a different fixing method, and the installer needs to know which one before the piece is packed, because the fixing hardware ships with it.
Material and air system
Double-layer PVC is the general construction. 0.4 mm PVC is used on large-format projects, and 0.5 / 0.6 / 0.7 mm PVC mesh where the structure carries load, spans further or faces sustained exposure.
The air system is sized to the piece: the 650 W electric pump moves 1,600–2,000 L/min at 2.0 psi and suits smaller spheres, compact displays and short-duration indoor installations; the 1600 W electric pump moves 4,800–5,200 L/min at 4.5 psi for large-format structures, arches and continuously inflated outdoor displays. Both run on 110–240 V, 50–60 Hz, and the destination plug type is confirmed on the order.
Print area and sponsor panels
Send print-ready vector artwork with colour references, and say which marks are sponsor-owned and which are yours. On an arch the crown carries the main lockup and the legs carry the secondary panels, so the split is agreed before printing rather than argued about afterwards.
A curved crown turns away from the viewer, which compresses type across the top of the span. Where a layout depends on type reading square, the usual answers are a straight-sided profile or a flat printed panel set into the span, and the mockup shows which one you are approving.
Lead time, quantity and freight
MOQ is 1 piece for most custom projects, so a single piece can be approved before a repeat order. Pattern and print setup are paid once per design, so a second unit costs less per piece than the first.
Bulk production typically takes 3–8 days for simple items, 7–15 days for standard custom work and 15–25 days for complex or large pieces, counted from final design approval. Freight comes on top: express or air usually 4–15 working days, and sea, rail or truck usually 20–45 days, after dispatch and subject to route and customs
All of these sit under inflatable arches, where the shared specifications and the full buyer checklist live.
