Product Description

EVT290S-SSBP Heavy-Duty Stainless Steel Base Plate with Concrete Anchor Holes | EVT290S Series Compatible

The EVT290S-SSBP Stainless Steel Base Plate is a professional-grade, high-ballast foundation component designed specifically for EVT290S 290 mm square conical aluminum truss systems. Engineered for permanent or semi-permanent installations, this plate is constructed from 9 mm thick Q235 stainless steel, providing the extreme weight and corrosion resistance required for outdoor environments, high-humidity settings, and structural lighting totems where standard aluminum plates may be insufficient.

Finished in a clean brushed stainless steel appearance, the SSBP delivers long-lasting performance and a professional aesthetic that resists rust and environmental degradation. It features five integrated concrete anchor points (14.28 mm / 0.562 in) designed to accept 0.5-inch concrete anchors, ensuring maximum structural security for fixed builds. The plate utilizes a secure conical connection system, which must be fastened using Couplers, Pins, and R-clips to maintain structural safety and load continuity.

Weighing 34.6 lb (15.69 kg), this heavy-duty plate provides a significantly more stable center of gravity than aluminum alternatives. It is the ideal choice for EVT290S 290 mm square truss applications in commercial architecture, permanent stage grids, and outdoor event structures requiring a fixed, anchored foundation with a professional metal finish.

Key Features

Designed by Evolve Truss, the EVT290S-SSBP is the definitive structural foundation for engineers and installers who require uncompromised strength and permanent anchoring for 290 mm square truss builds.

⚠️ Safety & Engineering Notice

❗ Critical Anchoring Information: When using the integrated anchor points, ensure the substrate (concrete or stone) is of sufficient thickness and strength to meet engineering requirements. Always consult a licensed professional engineer to determine the appropriate anchor type and wind-load calculations for your specific installation.

Important Guidelines for Safe Use:

• Never exceed the rated load capacity of the truss system or base plate.
• No loads shall be supported directly from truss connection points.
• Inspect the base plate before every use; do not use if bent, cracked, or deformed.
• Handle with care—due to the weight of this item, use proper lifting techniques to avoid injury.
• Assembly and installation must be performed only by trained and qualified personnel.
• Ensure all Couplers, Pins, and R-clips are correctly installed and fully secured.
• Account for all applicable forces, including dynamic and transverse forces such as wind loads.
• Do not mix truss components from different manufacturers.
• All truss structures must be reviewed and approved by a licensed professional engineer.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify all dimensions before integrating with other truss brands.
• Confirm conical connector type, node spacing, and system geometry.
• Mixing components without verification may compromise structural integrity and safety.
