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 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 device, have each designed their own versions.
Let’s start with Trellidor.

levels of security offered by each of its predecessor.

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

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.
