Bifold doors – S03™ Concertina Steel Security Door, by Trellis Doors

ATDC™™’s S03™ Platinum-class internal bi-fold doors are heavy duty and fully-framed for extra protection. These bi-fold doors are the perfect way to enjoy a wide-open lifestyle without leaving your home open to intruders and thieves.

Features:

• Extra thick steel means extra strength
  20mm x 5mm flat bars make up the cross linkages on this system. The uprights are made from custom-made, fully-framed, galvanised 20mm steel tubing. This Security Door is made from 95% solid steel for strength not matched by other manufacturers. It weighs 13kg per square metre, meaning extra heavy duty protection for your home.
• Security-plus
  The locking cylinder fitted to these bi-fold doors is made by a subsidiary of Assa Abloy and locks at three points to ensure that your security system cannot be easily defeated.
• Corrosion resistance-plus means long-life
  The S03™ security door has been treated, epoxy powdercoated and galvanised against corrosion. It also features corrosion-resistant solid brass rivets which are engaged in a non-pivoting position to ensure no mechanical weakening.
• Colour options
  S03™ bi-fold doors are available in 2 standard exterior quality colours (Black Satin and Pearl White) and with a short extension on the regular production time they can be matched to your home perfectly using the Dulux PowderCoat range.
• Flexible application means the S03™ is right for you
  Suitable for securing front doors, patio doors, glass sliding doors, french doors, windows and carports. The S03™ can fit any opening. It can be locked on the left or the right and can be fitted to the inside or outside of existing doors on masonry or timber substrates.
• Security Screws used on External Fixings
  Whenever a screw is required on the external side of a security door or security window we use industry-leading security screws that cannot be undone with ordinary tools, to increase your protection.
• Unobtrusive – Practically invisible
  By day the S03™ is practically invisible, folding away behind curtains or blinds. Visitors to your home will not notice it is there yet at night or when you are away you can sleep well, assured that the strongest kind of security door is protecting your family and investments.
• Increase the value of your home versus black security screens
  Unlike fixed black security screens that protect but look unsightly, our products disappear when you don’t need them to secure your property. Let the sunshine and breeze flow freely during the day, and use the S03™ to protect your home securely at night.
• Custom Made
  Measurement and fitting is carried out by our design team.
• Unique Quick-Action Keyless Lock Improves Protection
  The Slamlock which is fitted to the S03™ bi-fold doors locks instantly as the door is shut. It features a 12mm pin for extra strength, 3 locking points for maximum grip and a double hook for extra strength!
• Bottom Track Flexibility
  Bottom track can be fixed, removable or hinged so that it does not create a trip hazard or unsightly line.
