Engineered for high-traffic public occupancy, structural durability, and code-compliant emergency egress.
Strategic hardware deployment, fire-rated envelope integrity, and high-load mechanical panic exit mechanics for global infrastructure.
Engineered for over 1,000,000 operational cycles, our heavy-duty rim exit devices, surface vertical rods (SVR), and concealed vertical rods (CVR) ensure immediate unlatching under single-touch pressure during emergency evacuations.
Seamlessly integrated with modern Access Control Systems (ACS) and Building Management Systems (BMS), our electric panic doors feature solenoid-driven or motorized latch retraction (EL/QEL) for remote unlocking and automated emergency release.
Designed for extreme coastal climates, our panic entrance assemblies feature Florida Notice of Acceptance (NOA) and Miami-Dade approvals, combining heavy-gauge thermal break aluminum extrusions with laminated impact glass layers.
Technical Insight for Specifiers: Emergency egress systems are not merely hardware components; they form the final critical defense line in building life safety engineering. OEM/ODM compliance requires balancing immediate internal mechanical release (push bar pressure < 15 lbf / 67 N) with robust exterior forced-entry resistance.
Navigating strict regional building codes, fire regulations, and occupant load dynamics across international jurisdictions.
Under the International Building Code (IBC) and NFPA 101 Life Safety Code, commercial spaces with occupant loads exceeding 50 persons require UL 305 certified panic hardware. High-velocity hurricane zones (HVHZ) such as Florida further demand TAS 201/202/203 structural missile impact testing, placing Grandex at the forefront of US compliance.
European standards separate egress solutions into EN 1125 (for panic exit devices in public assembly areas where panic situations may arise) and EN 179 (for emergency exit devices used by trained personnel). Our manufacturing matrix supports both CE and UKCA compliant multi-point locking systems with thermal barrier frames.
Rapid urbanization in the GCC and Asia-Pacific regions has led to massive demand for high-occupancy commercial towers, international airports, and logistics complexes. Grandex supplies customized aluminum glass storefront exit doors built to withstand extreme thermal expansion, high ambient heat, and desert wind load requirements.
Deep-rooted manufacturing excellence backed by automated CNC precision, 45-member QA team, and certified global exports.
