Security Gates
If you’re not familiar with expandable security gates, you’re
missing out! In a nutshell these types of security gates have
been designed for ease of use, aesthetic value yet with high
levels of security in mind. With mechanisms that allow instant
locking that negate the need for keys, high grade rollers and
tracks that are tamper proof, nylon fitments that prevent wear
and tear and the ability to open out of sight. These doors are
much sought after by most discerning home owners.
In South Africa there are really only three major suppliers of
these types of security gates – granted they can be bought off
the shelf and fitted yourself, but you will still notice one of
these brand names on them. Each supplier however while offering
an expandable security gate with instant locking devise, have
each designed their own versions. Let’s start with Trellidor.
Trellidor Range of Gates
Trellidor offer three designs. The Trellidor Standard which is
recommended for high risk areas, the Trellidor Plus recommended
for very high risk areas and lastly the Trojan which is
recommended for high to extreme risk areas.
Each however is constructed using basically the same materials
and design which are:-
• Powder coated galvanised steel in standard or non standard
colours
• Are all custom fit
• Suitable for doors and windows
• Offer different choice in patented locking systems
• Tamper proof fittings
• Maximum strength shoulder slides and bottoms tracks
• Guaranteed for 3 years in coastal areas and 5 years inland
Yet, each model offers slightly different features which affect
the levels of security offered by each of its predecessor.
Trellidor offer a choice of either a dead-lock system or
slam-lock system. The dead-lock does make use of a key to open
and close and offer a draw-bolt that locks into place which
offers a pull out strength exceeding 1000kg’s. You also get to
choose the position and height of the lock. It offers a five pin
cylinder with custom cams and allows you to use one key for all
security gates throughout your home.
Their slam-lock on the other hand requires no keys and offers
three modes of operation. Open mode allows you to open or close
the door without locking it, the slam-lock mode allows automatic
locking in times of emergency while the dead-lock mode fixes the
latches in place and prevents it from being tampered with.
MaxiDor
At the top of their range, Maxidor offer the Maxidor MXM.
This security door comes stand with a slam-lock mechanism, has a
low profile bottom track, no moving metal onto metal parts,
double uprights between its posts and incredibly strong
connectors. It is a door that is recommended for almost any
applications including doors and windows.
The Maxidor D12 offer high value for money and also comes
standard with 2 x two point slam-locks, the specifications are
almost identical to the MXM except for its design. Where the MXM
is suitable for high-end applications, the D12 is available at a
more affordable price tag.

An Overview of the Options
Expandable security gates are available either fully framed or
not. Most operate on a system of bottom and top tracks, but they
are also available without while still offering high levels of
security. The trackless type of expandable security gate allows
users the ability to swing or fold it away once fully opened
which is helpful in tight spaces. Bear in mind that an
expandable gate will take up anything between 15%-20% of the
door space when fully opened.
While most offer a slam-lock mechanism for safety and ease of
use, some doors are still offered with a mechanism that requires
a key to open and close and on request most gates can be fitted
with this type of locking mechanism.
With powder coating and galvanised steel options, you need not
worry about installing an expandable security door at the coast.
And you get the option of a host of colours.
Most expandable gates are custom made which helps take care of
uneven areas.
