Description

EVT12S-3FT | 3-Foot Aluminum Truss Section (12×12 Box Truss Plated)

The EVT12S-3FT Aluminum Truss Section is a 3-foot straight segment for 12-inch square end-plated aluminum truss systems — the mid-short workhorse that lands on more parts lists than any other sub-5-foot length because three feet divides cleanly into the booth dimensions, stage footprints, and structural grids that define the industry. At 36 inches, this section sits at the crossover point between compact gap-fillers and full-span straights: long enough to carry meaningful load between support points on its own, short enough for a single crew member to lift, carry, and align without a second pair of hands. Trade show general contractors pulling lengths off the truck to frame 10×10 inline booths and 10×20 island exhibits, outdoor festival scaffolding teams stacking delay towers on uneven ground, university theater departments building lighting bars in low-ceiling black boxes, and agricultural facility managers mounting sensor grids between greenhouse posts all reach for the 3-foot first — it’s the section that shows up in multiples on every order because the math keeps calling for it.

Function & Compatibility:

The EVT12S-3FT assembles via bolted end-plates — no conical couplers involved. It carries the same 12-inch square cross-section, four-chord geometry, and through-bolt plate pattern as every other component in the EVT12S family, from the smallest spacer to the longest straight. Built entirely from 6061-T6 aluminum alloy, the 3-foot section delivers the same structural grade and connection continuity as the 5-foot and 10-foot lengths it commonly pairs with. Full diagonal bracing spans the entire 36-inch length, giving this section standalone lateral rigidity — it functions equally well as a horizontal overhead bar, a vertical tower leg, a ground-support base frame member, or a filler segment between corners in a complex grid layout. Three of these sections plus a 1-foot spacer reach a clean 10-foot span; two reach 6 feet; combined with a 2-foot section they hit 8 feet — the kind of arithmetic versatility that keeps the 3-foot in constant rotation across builds of every size.

Key Features

• Versatile Mid-Short Length: A complete 3-foot (36-inch) truss segment with full diagonal bracing — long enough to span between support points as a structural member, compact enough for one person to handle during load-in, and arithmetically compatible with standard 10-foot, 6-foot, and 8-foot layout dimensions.
• Standard Aluminum Finish: Brushed aluminum surface matching every other silver EVT12S piece — consistent appearance across mixed-length builds without surface variation between sections.
• Ready-to-Assemble Hardware: Includes 4x Grade 8 Bolts, Nuts, and Washers in every box — no separate hardware order required to bolt into a run immediately on delivery.
• Structural-Grade Material: Constructed from 6061-T6 aluminum — the same alloy specification running through the entire EVT12S product line, preserving load path continuity across every bolted joint.
• Universal End-Plate Format: Standard EVT12S through-bolt plate geometry, cross-compatible with other 12-inch plated truss systems using the same bolt pattern and plate dimensions — including Tomcat, James Thomas, Milos, and Show Solutions.
• TÜV Specifications: Produced under TÜV-certified manufacturing standards — the 3-foot section carries the same engineering certification as every other straight length in the EVT12S catalog.

Who It’s For

• Trade Show General Contractors & Exhibit Houses — You’re framing inline booths, island exhibits, and overhead banner structures where booth footprints are measured in exact 10×10 or 10×20 increments. The 3-foot section is one of the most frequently pulled lengths from the truck because the math works: three sections plus a 1-foot spacer hits a clean 10-foot span, two sections make 6 feet, and combining with a 2-foot reaches 8. It’s the building block that lets you assemble virtually any standard booth dimension from a single repeatable length without carrying a dozen different sizes in inventory.
• Outdoor Festival & Event Scaffolding Teams — You’re constructing delay towers, front-of-house mix platforms, and camera riser structures in open fields where ground conditions shift between events and site dimensions are never the same twice. A 3-foot section gives you a manageable building block that one crew member can carry across soft ground, position on uneven terrain, and align against a sleeve block or base plate without waiting for a second hand — while still providing enough span between support points to create stable, self-supporting tower legs and platform frames.
• University & School Theater Technical Departments — You’re maintaining a truss inventory that serves multiple productions across an entire season in venues with limited fly space and low grid heights. The 3-foot section is short enough to maneuver inside a small black-box theater or recital hall — through narrow doorways, around low ceilings, past fixed seating risers — yet long enough to serve as a horizontal lighting bar for a full wash position or a vertical side-light tower without needing multiple sections bolted together to reach a usable length.
• Agricultural & Horticultural Facility Managers — You’re incorporating truss sections into greenhouse overhead rail systems, irrigation boom supports, and climate-sensor mounting grids where the distance between structural posts is often three feet or less. The aluminum construction resists corrosion in the high-humidity growing environments that destroy steel hardware in a single season, and the modular bolt connection lets you reconfigure the overhead grid as crop layouts, growing tables, and irrigation zones shift between planting cycles.
• Rigging & Structural Engineers — The EVT12S-3FT is a fully braced structural section with the same 6061-T6 alloy specification and TÜV-certified fabrication as every other EVT12S component. It appears on an engineered drawing as a standard cataloged section in any orientation — horizontal, vertical, or angled. Refer to the official EVT12S load tables for allowable loads at the specific total span length in your design.

Designed by Evolve Truss, the EVT12S-3FT is the mid-short section that keeps showing up on every parts list — the 3-foot piece that divides evenly into standard dimensions, handles like a one-person component, and builds everything from a single booth frame to a multi-story tower.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: The rated load capacity for this 3-foot segment depends on the full system configuration — total span length, support conditions, and loading type all determine allowable capacity. For precise load specifications, always refer to the official EVT12S Truss Series Load Tables for the span you are building. Consult a qualified engineer before use.

Important Guidelines for Safe Use:

• Inspect the end plates and bolt holes for deformation or wear before every use.
• Ensure all Grade 8 bolts are properly torqued to manufacturer specifications.
• Do not mix truss components from different manufacturers unless the bolt pattern and plate dimensions have been strictly verified.
• The purchase of this product does not authorize specific installations; a licensed professional engineer shall review all structures, lighting plots, or other aluminum truss uses.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify Bolt Patterns: Plated truss varies by manufacturer. Compare your existing truss plate dimensions against EVT12S specifications before purchase.
• Check Alignment: Ensure chord alignment is precise to prevent uneven loading on the bolts.
• Mixing incompatible plated truss can lead to structural failure.
