12 ft. x 16 ft. Portable Modular Stage Package with 3-Step Staircase, Twelve 4 ft. x 4 ft. Non-Slip Deck Pa

Overview

Introducing the ProX XSU-PKG12X16-4X4ST3 12 ft. x 16 ft. Portable Stage Package with 3-Step Stairs, a complete, all-in-one stage solution built for event producers, production companies, and performing arts organizations who need a serious, professional-grade platform at a larger scale. When your production demands a stage that commands the room, this package delivers a 192 sq. ft. performance surface that goes up without the chaos of sourcing individual components and holds up through everything the show throws at it. Whether the setting is a live concert, a corporate conference, an outdoor festival, a house of worship production, or a school or community event, the ProX XSU-PKG12X16-4X4ST3 gives you a clean, stable, and polished stage backed by the build quality professionals have counted on since 1984. The included 3-step staircase makes this package especially well suited for elevated stage configurations, giving performers and crew a gradual, comfortable, and safer approach to the platform when compared to a tighter 2-step setup.

The Platform The ProX XSU-PKG12X16-4X4ST3 is built around a modular panel system using individual 4 ft. x 4 ft. deck sections that lock together to form a unified 12 ft. x 16 ft. performance surface. Each deck panel is constructed with AAA grade 15mm / 0.59 inch exterior rated birch plywood with minimal voids, topped with a non-slip black surface that keeps footing secure for performers and crew under real show conditions. The panels connect using the integrated aluminum framing system, producing a tight, gap-free surface with no flex or shift once fully assembled. At this footprint, the platform gives you the kind of stage presence that fits headliner sets, full production builds, and events where the stage itself is part of the statement.

The Frame and Legs The supporting structure throughout is built from extruded aluminum, keeping the overall package at a manageable weight while maintaining the structural integrity a large stage demands. The adjustable legs thread in and out to set your preferred stage height and accommodate leveling on uneven floors or outdoor terrain. Each leg is capped with a leveling foot for precise, on-site field adjustments. The underside of the platform features a cross-braced aluminum framework that distributes weight evenly across the full footprint, supporting consistent load across every section of the stage.

Adjustable Legs Each platform section includes six telescoping legs adjustable from 16" to 22", with a maximum fully extended height of 24". A locking pin safety system holds the selected height firmly in place during use. Every leg is also equipped with micro adjustable leveling feet with M16 threaded bolts, allowing precise leveling on uneven surfaces for a secure, professional stage setup.

Weight Capacity Each 4 ft. x 4 ft. platform section is rated to support up to 800 lbs. when the load is evenly distributed, giving you a dependable and safe surface across the full 12 ft. x 16 ft. stage for performers, equipment, and high demand production environments.

The Staircase The package includes a 3-step aluminum staircase that attaches directly to the platform frame, providing performers and crew with a stable and secure point of entry. The three steps deliver a more gradual, comfortable climb compared to a 2-step configuration, which becomes particularly important at taller stage elevations where that extra step makes a genuine difference in comfort and safety during a busy live event. The stair treads carry the same non-slip surface treatment as the main deck panels, maintaining consistent footing from ground level all the way up to the performance surface. The staircase integrates cleanly with the overall structure.

Banister Railing The 3-step staircase includes dual banister railings running along both sides of the steps, giving everyone using the stairs a secure handhold on either side when getting on and off the platform. On a large format stage like this where foot traffic is higher and stage access is more frequent, the dual railing setup is a straightforward safety feature that matters in the real world.

Finishing and Accessories The ProX XSU-PKG12X16-4X4ST3 ships as a complete stage package. Stage skirts are not included but are available separately from ProX, giving you the option to finish the look of your stage with a clean front facade that conceals the underframe. The aluminum finish throughout the frame, legs, and staircase presents a polished, professional appearance that looks sharp even before skirts are added.

Portability and Setup Every component in this package is designed to break down and pack out. The modular panel design and tool-friendly assembly make setup and teardown manageable for working crews. The aluminum construction keeps individual pieces at a weight that a small crew can handle without specialized equipment, and the straightforward connection system means the stage can be up quickly and come down just as fast when the event is over.
