Commercial use changes the equation again.
A professional car transporter trailer can:
● load several vehicles weekly
● travel long distances
● experience constant braking loads
● handle rough yards
● face the pressure of time and imperfect maintenance
Here, structural stiffness becomes extremely important.
A steel car trailer often wins because:
● impact tolerance is higher
● repairability is easier
● reinforcement is simpler
● abuse tolerance is excellent
A premium aluminum car trailer can absolutely survive commercial work, but budget aluminum builds can fatigue faster if overloaded or poorly designed.
