EVT12S-4FT Black | 4-Foot Aluminum Truss Section (12x12 Box Truss Plated) – Matte Black

The EVT12S-4FT Black Aluminum Truss Section is a 4-foot straight segment finished in matte black powder coat, built for 12-inch square end-plated aluminum truss systems where the truss is both the structural backbone of the build and a visible element that the audience, the congregation, or the client will see. At 48 inches and 30 pounds, this is the workhorse-length black section that professionals order in multiples to assemble full front-of-house spans, permanent overhead grids, and premium exhibit structures — all in a non-reflective finish that lets the lighting, the display, or the architecture command attention instead of the hardware holding it up. Concert lighting designers building front truss that sits in direct audience sightlines, museum fabricators suspending track-lit display frameworks from gallery ceilings, mega-church production teams gridding sanctuaries that seat thousands, and convention center rigging departments stocking dark-finish inventory for premium booth builds all specify the 4-foot black because they need a section that scales into real spans and ships ready to install without a single coat of field paint.

Function & Compatibility:

The EVT12S-4FT Black is a bolted end-plate truss section — not a conical coupler product. Under the factory-applied matte black powder coat sits the same 6061-T6 aluminum alloy structure, four-chord profile, and through-bolt plate geometry as every other EVT12S component — structurally identical to the standard brushed aluminum 4-foot section in every measurable way. Full diagonal bracing runs the entire 48-inch length, providing standalone lateral rigidity whether the section is installed horizontally, vertically, or at an angle. The finish integrates seamlessly with other black EVT12S components for a uniform dark rig, and it drops into mixed-finish builds where only the visible portions of the structure need the dark treatment. Three sections make a 12-foot front truss. Five sections build a 20-foot overhead span. The math works the same as the silver version — the only difference is what the audience sees.

Key Features

• Workhorse Length in Dark Finish: A complete 4-foot (48-inch) truss segment with full diagonal bracing and matte black powder coat — the section ordered in multiples for front-of-house spans, overhead grids, and tower builds where the structure sits in audience sightlines and reflective aluminum is not an option.
• Factory Matte Black Powder Coat: Durable non-reflective finish applied at the Evolve Truss production facility — arrives ready for installation in concert rigs, gallery environments, worship facilities, and convention halls without on-site painting, wrapping, or finish coordination.
• Included Hardware: Ships with 4x Grade 8 Bolts, Nuts, and Washers (black finish hardware may vary; standard zinc/galv typically supplied unless specified) — bulk orders arrive complete and bolt together on delivery.
• Structural Parity with Standard Aluminum: 6061-T6 aluminum alloy beneath the finish — identical material specification, identical load capacity, identical 30 lb weight. The powder coat adds visual performance without altering structural performance.
• End-Plated Connection: Standard EVT12S through-bolt plate format, cross-compatible with other 12-inch plated truss systems sharing the same bolt pattern and plate dimensions — works in all-black systems or mixed silver-and-black configurations.
• TÜV Specifications: Fabricated under TÜV-certified manufacturing processes — the coating is a surface treatment that does not affect the engineering certification, load path, or connection integrity.

Who It's For

• Concert & Festival Lighting Designers — You're specifying front truss, mid-stage truss, and side-light tower sections that sit in direct audience sightlines throughout the show. At 4 feet per section, your crew builds 12-foot, 16-foot, and 20-foot front-of-house spans from a small count of identical pieces — and the matte black finish ensures the structure recedes behind the lighting design it supports rather than competing with it. On festivals where multiple stages share the same truss inventory, the dark finish reads clean under any color wash without throwing reflections into the crowd or the camera.
• Museum & Gallery Exhibit Fabricators — You're building suspended display frameworks, partition walls with integrated track lighting, and interactive installation supports inside galleries where the curated visual environment leaves no room for exposed industrial hardware. A 4-foot black section spans between ceiling attachment points at standard bay widths, holding directional fixtures and hanging hardware while reading as a deliberate architectural element rather than backstage rigging. The factory finish eliminates the spray-booth step from your fabrication timeline.
• Mega-Church & Large Worship Facility Production Teams — You're installing permanent overhead grids that carry moving lights, projection screens, line array speakers, and camera positioning systems in sanctuaries seating thousands. Building committees and architects require the technology layer to disappear against vaulted ceilings and exposed timber trusses — the matte black finish satisfies that requirement at the spec stage. The 4-foot length aligns with the facility's structural column spacing, letting your grid tie directly into the building's primary steel without intermediate hangers that complicate the ceiling aesthetic.
• Convention Center In-House Rigging Departments — You're maintaining a standing black truss inventory for exhibitors requesting dark-finish overhead structures for premium booth builds, product launch stages, and keynote presentation sets. The 4-foot section is the most requested length in the fleet because it scales efficiently into standard 10x10, 10x20, and 20x20 booth footprints while keeping piece count and assembly time manageable for union labor crews working under strict setup windows — fewer connections per span means faster builds and fewer bolts to inspect at strike.
• Rigging & Structural Engineers — The finish is cosmetic; the load path is structural. The EVT12S-4FT Black is a fully braced truss section with the same 6061-T6 alloy specification, TÜV-certified fabrication, and Grade 8 bolt hardware as the brushed aluminum version. It carries identical structural authority on an engineered drawing — refer to the official EVT12S load tables for allowable loads at the total span length and support configuration in your design.

Designed by Evolve Truss, the EVT12S-4FT Black is the dark-finish workhorse you stock deep and deploy across every visible span — a 4-foot section that builds full production grids, satisfies aesthetic specs, and arrives ready to bolt in without a minute of finish work.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: The rated load capacity for this 4-foot segment is governed by the overall system design — span length, support spacing, and load distribution all factor into the allowable capacity. For precise specifications, always refer to the official EVT12S Truss Series Load Tables for the span configuration 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.
• Handle with care to prevent chipping the powder coat finish — exposed aluminum beneath the coating compromises the visual consistency of a black-out rig.
• 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.
