• Inna-Dor


    Internal fire resistant steel doors

    A highly cost-effective single solution, offering an aesthetic design, durable construction and up to 4 hours fire protection. The doors, fitted in internal applications in a wide variety of wall constructions, are designed to protect personnel and property from the spread of flames & smoke. INNA-DOR offers substantial benefits over comparable timber doors in strength, durability & security. The range has been tested to BS 476 Parts 20 & 22 and BS EN 1634.

    Contemporary, Durable & Cost Effective

    The contemporary flush design allows for INNA-DOR to be used in a wide range of internal applications, from schools and offices to hotels and supermarkets. The wide range of variants available – sizes, panels, hardware, colours and pattern designs – means INNA-DOR is perfect for all internal applications.

    We use corrosion-resistant Magnelis© steel to manufacture INNA-DOR, meaning it is well protected from potentially harmful elements in the environment it’s installed. When paired with one of our enhanced Polyester Powder Coat finishes, we can offer up to 10 years anti-corrosion guarantee (subject to site location).

    Our doorsets are supplied fully assembled with hardware fitted as standard. When this is combined with our adjustable fixing feet and variable sub-frame, the installation time is drastically reduced, which in turn adds value to a project. The single fix design of our doors offers greater cost savings when priced against overall installation times for timber doors. Also, the inherent durability of steel means that in areas of high traffic or potential abuse, the ‘whole life’ cost of a steel doorset significantly outweighs that of a timber dooret.
