Product overview

ST20-36

The ST20-36 is a 0.914 m (3.0 ft) square aluminum box-truss straight section with a 20.5" × 20.5" (520.7 mm × 520.7 mm) outer profile, manufactured from EN AW-6082-T6 aluminum. It features 50×3 mm main chords and 25×3 mm brace tubes, matching the SPEEDTRUSS ST20 BOLT series for modular mixing with industry-standard GS20 / ST2020 systems. Net weight is 18.3 kg (40.3 lb); gross weight 20.8 kg (45.9 lb) including bolts and packaging. Ideal for medium-span modules, stage side walls, and production house framing.

The bolt-plate end connection uses the industry standard plated bolt pattern shared by leading 20.5" box truss systems, joined with 5/8" Grade 8 steel bolts. High-strength bolts, nuts, and washers are included per section. Compatible with 20.5" corner blocks, spacers, base plates, and ground-support sleeve blocks for flexible system builds. TÜV SÜD and CE certified for professional concert touring, large-scale staging, exhibition, and rental applications.

Always inspect bolt hardware and end plates before use. Configure loads according to the structural plan and manufacturer load charts — do not overload. Refer to ST20 span/load tables for allowable uniform, centre-point, and third-point loading.
