Alphador is our single upright retractable door, offers strength and value for money and is suited to medium risk security needs. Just as with all our other burglar gates and doors, property owners can expect durable quality, Engineered to Last when investing in the Alphador.
We manufacture our Alphador with a larger single upright and with a top and bottom track. Although a single upright is used, the cross braces are fitted directly onto the facing side of the tubing. For added strength, a steel sleeve is inserted into the inner tubing, strengthening the fitting of the cross bracing. Alphador is fitted with a stainless steel slam lock, with an auto dead-lock feature.
Alphadors are manufactured to specific high-standards, and all Alphadors are fully custom-made to order. A variety of exterior Polyester powder coating colours are available.
Technical Specifications of the Alphador
- All-steel construction for superior strength
- Single 17 mm x 24 mm upright x 1.0 mm gauge steel uprights
- Fully galvanized Z275 galv. coating (32 microns thick) for rust protection and a longer life expectancy
- 3 rows of cross-bracing – temper-roll-hardened and zinc-electroplated-galvanised
- Four-sided steel frame allows for a more precise reveal fitting without any spaces, making leverage more difficult
- Pre-lubricated sealed steel roller bearings and axles are used (no plastic or nylon)
- A single metal zinc guide is used at the bottom of every upright for a smooth motion in the captured bottom track
- Low profile, non-trip, half-moon-shape bottom track that is easy to traverse
- The top track, bottom track and lock channel are rolled with 180-degree Dutch bend folds for extra strength and improved paint adhesion
- Lock channels designed to make fixing points concealed
- Exterior Polyester powder coating is used (not less than 80 microns thick) and is fade-resistant
- The lock is a patented stainless steel lock with a 45-degree cam cylinder, making it far more difficult to dislodge the cylinder when struck by heavy hammers or other objects
