General purpose doors - which give high security to places such as hospitals, shops, industrial units and domestic homes.  
Communal entrance - doors which are very durable, vandal proof, with intercom type entry, electro-magnetic locks and polycarbonate glass, ideal for office blocks, tower blocks and colleges.  
Louvered doors - giving a strong and practical solution where ventilation is needed, ideal for sub-stations and plant rooms. 
High security doors – Where security is taken to the extreme, ideal for high risk areas and prisons, etc.

Frames 
Our non-welded frames are constructed from 2mm thick folded steel sections, which support the full range of Marley doors. Available in two size options, the frames are suitable for a wide range of openings. They are reinforced in the corners and secured to the wall cavity through pre-punched fixing holes which are concealed from view. 
 
Thresholds 
The frame sets are complete with bottom thresholds in standard or low profile options which cater for all throughways. They are also available without a bottom threshold. Low profile/ramped thresholds provide an ideal solution where trolley or wheel chair access is required. 
 
Standard Security Features 
Anti-jemmy hinge – Stopping all attacks made by crowbars and levers 
Dog Bolts – Providing extra security by locking the door into the frame on both sides 
Stainless Steel Hinges – Adding extra strength and rust free operation 
 
Customise Your Door 
Customise your door further with a spy viewer, letterbox, a choice of vision panels or louvered sections. Additional top or side panels are available and constructed from the same material as the doors.
