Our steel square-edged door system: Engineered for strength and style.

Metador’s Defender Duopar is Metador’s more innovative solution to internal access. The ready-to-install two-part frame system is designed for aesthetic internal use, transforming industrial steel doors into sleek, modern entrances that suit various environments, while addressing installer pain points and offering a range of features and upgrades.

Where are square-edged doorsets best suited?

Our clients choose the Defender Duopar due to its elegant appearance, superior strength, and ease of installation. The clamp-style frame system meets the demanding requirements of commercial sectors such as:

• Offices
• Hospitals and Health Care
• Retail

Features of the Defender Duopar

These door and frame systems are designed and manufactured with completely concealed fixings and feature styling consistent with a typical timber-framed doorset. While typically paired with our steel door leaves, you can also combine the Duopar steel frames with timber/laminate door leaves. Please speak with our helpful team for more information.

An excellent feature of the clamp-style frame is its ability to fit any aperture without the need for finishing, making installation the final step in the process. This feature minimises the risk of door damage from other trades, as it requires no further work to or around the doorset.

We offer an extensive range of hardware & access control options for your square-edge doorset, including electronic locking.

Additional Upgrades

With the Defender Duopar, we offer fire ratings of E30 or E60 for internal use, as well as acoustic ratings of up to 37 dB. These doorsets are available in any required RAL colour or can be powder-coated with our special finishes to suit their environments. See our range of colours and finishes here.
