Aluminum cantilever gate built on 6005-T6 beams
Lighter than steel, free of rust bleed, and finished in AkzoNobel Interpon powder tested to AAMA 2603.


Four beam profiles, chosen per gate
We offer four 6005-T6 aluminum cantilever beam profiles with different section sizes and wall thicknesses. The beam is picked from your gate length, height, infill design and load, not from a one-size catalog.
The largest bottom beam measures 302 x 213 mm with walls up to 7.0 mm at the critical load points. The top beam is 113 x 93 mm with 2 to 6 mm walls. Vertical bars are 6063-T5, 47 x 37 mm.
- Lower leaf weight means less load on the carriage and motor
- No rust staining on posts or paving
- Bolt-together tenon-and-mortise frame, little site welding

AkzoNobel Interpon finish as standard
Standard gates are coated with AkzoNobel Interpon D1000 architectural powder, which meets AAMA 2603 and Qualicoat Class 1. For coastal or high-UV projects you can upgrade to Interpon D2000, which meets AAMA 2604 and Qualicoat Class 2.
Our coating line runs a double high-temperature cure. CAIMEN holds an AkzoNobel retail windows and doors partnership certificate, number CN6002WD, valid through 2026.
