Longhua in Shenzhen has all kinds of commercial properties. Electric rolling doors are used on everything from small shops to factory entrances. What material should you pick? There's no absolute best, just what fits your situation.
PVC High-Speed Doors
These use PVC fabric curtains that run up and down fast. They're light, the motor works efficiently, and maintenance is easy. If the fabric gets torn, just swap the curtain. No need to replace the whole door. Good for indoor industrial areas, clean rooms, and internal passages where you just need fast opening and insect control.
Aluminum Alloy Rolling Doors
Lightweight, no rust, many color options. Downside is they're not as strong as steel. Suits small storefronts, shops, and places that don't need heavy security.
Stainless Steel Rolling Doors
Strong, rust-proof, shiny and clean-looking. No paint peeling or fading. They last long and look professional. Common on high-end stores, banks, and places that need a refined look and good security.
Color-Coated Steel Rolling Doors
Lots of color choices. The coating protects the steel underneath. Decent weather resistance, reasonable price. Popular for general commercial use.
Fire Shutters
When fire resistance is your main concern, choose these. Steel fire shutters for standard openings, inorganic fabric fire shutters for large openings in commercial complexes or underground garages.
How to Choose
What actually matters: where are you installing it? Indoor or outdoor? Need security or just privacy? Tight budget or looking for premium? Every material has trade-offs. Talk to a manufacturer, tell them your needs, let them recommend. Don't just go by price alone.
