What Each Material Does
You choose a curtain by what the opening asks of it. Aluminium slats stay light and quiet, so they suit doors that open and close all day. Steel slats take hits and heavy traffic without bending. PVC costs the least and fits shops where looks and budget matter more than brute strength. 304 stainless shrugs off rust in wet, salty, or food-grade spaces.
All four hang on the same motor and track. The material you pick changes the running feel, the load on the motor, and how long the shutter lasts far more than the motor does. If you size the motor to the curtain, you avoid strain and noise later. Think of the curtain as the working part. The box, the motor, and the slats all follow from it.
Weight and Cost
Aluminium lands in the middle. You can still lift it by hand if the power drops, and it spares the motor. Most shops find the price fair for the life it gives.
Steel weighs the most. It needs a bigger motor and a stronger frame, and that adds to the bill. You pay for toughness, not a bargain. Fit it where security matters more than smooth looks.
PVC is the lightest on the wallet. It keeps a small kiosk or stall affordable, as long as nobody tests its strength. It also runs the quietest, which helps in homes or clinics.
304 stainless asks the most up front. You buy it for the years it survives, not for a low sticker price. On a coastal or wash-down site, that maths works out over time.
Corrosion and Environment
Aluminium shrugs off rain and sun with little care. It serves most street-facing shops well.
Steel rusts once its coating breaks. Keep it dry, fix chips early, and it holds. Leave it, and it stains.
PVC ignores moisture but dislikes long heat and hard sun. It suits indoor spots or shaded fronts.
304 stainless is the coastal pick. Salt air that scars other metals leaves it clean. Near the sea, this is the one to watch. Its finish stays bright without paint, which keeps a front looking new.
Which Opening Wins
A shopfront with normal foot traffic? Aluminium gives the best balance of cost, weight, and life.
A warehouse or loading bay under daily knocks? Steel earns its keep.
A market stall or kiosk on a tight budget? PVC keeps the cost down.
A kitchen pass, a coastal café, or a clean room? 304 stainless pays off over time.
