EXAL Powerdoors are commonly installed at electricity substations, switching stations, generation sites, industrial facilities and other critical infrastructure where a robust, reliable door system is required. They are suitable for both new construction and refurbishment projects.
EXAL Powerdoors have been developed specifically for the demanding conditions found on electricity network sites. Their robust construction, corrosion-resistant hardware, proven locking systems and compatibility with restricted key systems and electronic access control make them a trusted choice for critical infrastructure throughout New Zealand.
Unlike a typical commercial or industrial door, EXAL Powerdoor has been engineered specifically for utility environments. Every component has been selected for durability, reliability and long service life, from the heavy-duty aluminium frame and composite door construction through to the marine-grade stainless steel hardware and high-quality locking systems.
