4040L 4N Aluminium strut profile – 40x40mm, 4N means that is has grooves on all four sides. The extruded profile is the most commonly used as it is extremely adaptive and strong.
This is your perfect partner when designing lightweight frames where you need strength. This profile it is often used as frame members when the load and/or size require load bearing capacity and/or stiffness. EMOX has designed several frame structures using this profile, frames that often are exposed to a lot of abuse and significant loading.
