ALUTRUSS DECOLOCK DQ4-4000 4-Point Truss – Lightweight Construction in XL Length for Decorative Applications

The ALUTRUSS DECOLOCK DQ4-4000 is a decorative 4-point truss with an impressive length of 400 cm. It is part of the proven DECOLOCK DQ4 system and was developed specifically for lightweight, visually appealing installations in trade show construction, retail design, storefront design, and interior design as well as clubs, theaters, and exhibitions. Despite its size, the truss remains lightweight and easy to assemble—perfect for creative and temporary as well as permanent applications.

Part of the DECOLOCK DQ4 lightweight construction system

The system is based on four conical connectors with pins and split pins, which ensure a force- and form-fitting connection. The proven Quick-Lock system enables quick, tool-free assembly—ideal for frequently changing setups at events, trade shows, or exhibitions. The compact external dimensions of just 22 x 22 cm ensure that even large structures remain elegant and space-saving.

Lightweight, stable, and flexible

Manufactured from 35 mm aluminum channel tubes with a 2 mm wall thickness and 10 mm struts (also 2 mm), the DQ4-4000 offers an excellent combination of low weightand sufficient load-bearing capacity for decorative elements. Weighing just 12.77 kg, it is particularly easy to transport—despite its 4-meter length.

Elegant design for visible installations

The aluminum-colored finish gives the truss a modern, technical look. It is also optionally available in any RAL color—ideal for CI-compliant trade show displays, design installations, or interior design with high brand recognition. The slender struts emphasize the delicate design and make the system a real eye-catcher.

Production takes place in Europe in accordance with the highest quality standards. The DECOLOCK DQ4 series is manufactured using the TIG pulse welding process with AlMg 5 welding material. The system complies with the VPLT Standard SQ P1 and is TÜV Süd certified. A load table for structural design is available online.

Perfect for creative designs with large spans
