Also specified as: Security Grille
A grill rolling shutter (security grille) of linked tubular or flat bars — maximum visibility and airflow with strong physical security for retail and public areas.
An open linked-bar grille that coils like a shutter — high visibility and airflow with genuine physical security.
The grill rolling shutter (security grille) is built from linked tubular or flat steel or aluminum bars rather than solid slats. The open lattice gives the widest possible visibility and airflow while still forming a strong physical barrier — the classic choice for shopfronts, mall units, ticket halls and any opening that must look open and inviting yet remain secure when closed.
Because the curtain is an open grille, it offers little wind resistance and excellent sight lines, and it can be powder-coated to any RAL color to complement the storefront. RAX manufactures the linked-bar curtain, barrel and guides in-house and supplies a tubular or geared motor with manual override and the full technical drawing package.
RAX-company facts on this page — materials, 100,000-cycle fatigue testing, certifications held, warranty and lead time — are from RAX Door Technology’s approved brand brief. Industry figures are marked [SOURCED] (with the source) or [ESTIMATE] (industry-typical, not independently verified) in the Basis column and are confirmed against your opening on the technical layout. Fire resistance (EI60/EI120) and wind-load class are project-specific capabilities we test and document per order — never blanket certificates.
Every door is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification.

Door body 2-year warranty · operator/motor 3 years (servo motor 5 years) · free spare parts within warranty, dispatched DHL/FedEx 5–7 days.
A grill rolling shutter forms a strong physical barrier from rigid linked steel or aluminum bars with end locking, so it deters and delays forced entry while staying visually open. Bar gauge and link geometry are matched to the security level you need.
A grill gives the maximum visibility and airflow of any rolling closure, which is why it is preferred for shopfronts, malls and public areas that must look open and inviting. A solid shutter gives more weather and privacy protection; a perforated shutter sits between the two.
Yes. The bars and metalwork are powder-coated to any RAL color, so the security grille complements the storefront branding and surrounding architecture.
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, wiring diagrams for your local installation team; operators are pre-set and tested before dispatch.
Held: ISO 9001:2015, CE to EN 13241 (industrial door) and EN 12453 (operator safety), with SGS material reports and Product Liability Insurance. Fire resistance (EI60/EI120) and the wind-load class are project-specific capabilities we test and certify per order against the matching standard – we never overclaim a blanket rating.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production. Tooling records are archived up to 5 years with no extra tooling fee on repeat orders, all under strict NDA.
