Trellis Retractable Security Gates Features

Unlike many cheap expandable security gates (Security Doors) designed and manufactured in South Africa, Maxidor’s expandable security doors such Our Maxi-Ultra, Maxi-Classi and MXA are functionally built with a pleasing aesthetics feature such our styled security bar flights, yet don’t compromise on strength.
To avoid environmental corrosive effects due to ambient moisture, rain, salt etc our Trellis Security Doors or Trellis Security Gates are polyester coated. The coating on our Trellis Retractable gates is applied electrostatically and is then cured under heat in our ovens to allow it to flow and form a protective skin to keep the trellis gates chemical protected from the environment.
All our Security Doors are powder coated at our factories before they are installed, this kind kind of coating is free flowing (dry powder), as compared to liquid paint used in other cheap doors. The main beneficial difference is that powder coated Security Doors by Maxidor Don’t require a solvent to make sure the binder and filler parts remain a liquid state
Our Trellis Doors fit against the substrate, frame and wall, using a specific engineering attachment security technique to avoid a physical mechanical device or tool to breach the door and gain entry via the font door or any other entry way.
Anti tampering (intentional malfunction or sabotage) screws are used in all our Retractable Trellis Security Gates, to avoid intentional sabotages by an unwanted intruder or thief.
Each Security door uses a permanent mechanical fastener (Rivet), to add to the stability of all moving parts when the door is in use (open and closing). Maxidor Uses high grade stainless steel rivets to minimises corrosion on the steel door rivet opening
Two rows of aesthetically pleasing styled flights and two rows of very strong unbreachable strong flights (diagonal attachment bars). This also includes options of various colour, and the number of Slam-Locks to be used.
