Security Roller Shutter — Built to Last
Our security roller shutters are engineered as your front line of defence — built from heavy-gauge galvanised steel or durable aluminium to resist forced entry, vandalism and weather. We supply independently tested SR1 through SR4 rated shutters with rapid manufacture and installation across the UK, typically within 2–4 working days.
Whether you need a single unit or a multi-site rollout, our team handles everything from initial survey through to final sign-off — with UK-wide coverage and fast turnaround times backed by a full workmanship guarantee.
What Makes It Stand Out
Every security roller shutter from Grewal is engineered to perform and built to last.
SR1 – SR4 Security Ratings
Every shutter carries an independently verified security rating — from entry-level SR1 to maximum-protection SR4.
Forced-Entry Resistant
Heavy-gauge steel construction with reinforced guides and anti-lift devices to defeat crowbars and power tools.
Insurance Compliant
Meets physical security requirements set by most UK commercial insurers — and may reduce your premium.
Smooth Remote Operation
Daily operation via remote fob, key switch, push button or group control systems — effortless every time.
Vandal-Proof Construction
Hardened curtain and surface finish resists graffiti, impact and tampering — keeping your frontage clean.
