Arcum Clearspan Structures

Architectural Profile,
Engineered performance

Arcum clearspan structures combine a curved roofline with a fully open interior to create space that looks intentional and performs like a building. From brand activations and VIP decks to seasonal patios and operational coverage, the Arcum delivers a modern profile that still works hard behind the scenes.

What is the Arcum?

Arcum structures are part of the clearspan family, meaning engineered aluminum frames without interior poles that maximize usable space. The signature arched roof delivers an architectural look while directing rain away. Their modular design adapts to any footprint, capacity, or site condition.

Arcum Sizing & Expansion

Available in several wide-span sizes, with modular bay expansion to match your footprint. Standard leg heights vary by width, with taller options available when you need additional clearance.

The Arcum is ideal for events that demand ample space, exceptional guest experience, standout branding, and striking visual presence, featuring a signature curved roofline that creates an architectural impression.

The Arcum does more than cover space—it defines it. Its signature curved roofline delivers a finished, architectural look onsite and in photos, making it a strong fit for highly visible projects.

Beyond the silhouette, the Arcum performs as a true clearspan solution. The fully open interior supports staging, furnishings, production needs, and efficient traffic flow. Engineered for demanding installs and multi-season use, it’s well-suited for projects that require more than a weekend tent.

The Arcum Clearspan

The Arcum emphasizes a curved, architectural roofline that elevates exterior presence and arrival impact.

The Levo Clearspan

The Levo is selected when the goal is a more design-forward clearspan profile and a premium guest experience with high visual impact.

Structure & System Coordination

The Arcum’s curved profile pairs with enclosure, flooring, and access systems that support circulation, environmental control, and clean presentation. Planning these elements early ensures the structure performs as intentionally as it looks.

Common Questions, Clear Answers

Clearspan structures can sound technical at first. These quick answers focus on the Arcum and give you the information most project managers and planners ask for when they start planning.

How is the Arcum different from other clearspan structures?

The Arcum structure shares the same engineered frame and open interior as other clearspans, but the roofline is curved instead of straight. That arched profile changes how the structure looks on site, softens the silhouette, and helps direct water off the top, which is useful for long-term and seasonal projects.

What sizes are available for the Arcum?

The Arcum clearspan is available in standard widths like 20m, 25m, and 30m. The length is built in 3m or 5m bays, which means we can adjust the structure to fit your site and layout instead of forcing your plan to fit a fixed size. Leg height is typically 4m or 5.4m, depending on the width. See Arcum sizing for additional information.

What types of projects are Arcum structures best for?

Arcum structures are a strong fit for high-end events, brand activations, hospitality decks, seasonal patios, and other projects where the structure is part of the visual experience. They also work well for long-term ticketing, registration, and operations hubs when you want a more architectural profile than a basic tent.

Can an Arcum stay up for multiple months or seasons?

Yes. Arcum clearspans are designed for both short-term events and long-term or seasonal use. During planning we will talk through site conditions, weather expectations, access needs, and any permitting so the setup, anchoring, and accessories are all chosen with longer durations in mind.

What information do you need to quote an Arcum for my site?

To quote an Arcum, we typically ask for event dates, location, expected headcount, and how you plan to use the interior. Site details such as surface type, available footprint, nearby buildings, utilities, and access routes for trucks help us recommend a size, layout, and anchoring plan that will actually work on the ground.

How is an Arcum anchored on pavement or where staking is limited?

When traditional staking is not possible or restricted, Arcum structures can be secured with engineered ballast. Our team will review your site plan and any underground utilities, then design an anchoring solution that protects the surface and meets engineering requirements.

Can I add glass walls, branding, and lighting inside an Arcum?

Yes. Arcum clearspans can be finished with glass or vinyl walls, branded panels, liners, doors, and integrated lighting or rigging. Many clients treat the Arcum as a branded environment, layering in signage, decor, and production elements so the structure feels like a custom venue rather than a temporary tent.

How far in advance should I book an Arcum structure?

The Arcum is a specialty structure and often books early for peak event seasons and large projects. For festivals, brand activations, and seasonal installs, it is best to reach out as soon as your dates and location are firm so we can reserve inventory, coordinate with your vendors, and support any permitting steps.

Want a clearspan that looks as good as it performs?

Send your footprint, event type, and timeline. We’ll recommend an Arcum clearspan configuration and help plan enclosures, entrances, and add-ons that make the space feel intentional and guest-ready.
