Retractable Grilles: The Perfect Solution for Stylish Security


Trellidor Retractable Grilles

When it comes to safeguarding your home or workplace, there are a plethora of security solutions available. However, none are quite as effective or stylish as retractable grilles. These grilles combine a classic appearance with a high level of protection, making them ideal for both homes and workplaces.

Flexible and Customisable

Retractable grilles are available in both standard and insurance-approved options, providing flexibility in terms of the level of protection you require. They are designed to keep intruders out while letting maximum light in, making them perfect for ground floor doors and windows.

Easy to Use and Install

Retractable grilles are easy to install and use, making them a popular choice for both residential and commercial spaces. They can be easily fitted to the face or within the reveal of a window or door aperture. The smallest bunch size available on the market ensures they don’t take up too much space, and they can be specified in a single or double-sash configuration. If a clear walkthrough is required, the security grille’s bottom track can be made to fold up or hinge aside.

High-Grade Steel Construction

Retractable grilles are made with high-grade steel construction in cross ‘X’ lattice as standard and ‘S’ lattice as an insurance-approved option. They provide a tough physical barrier and are a visual deterrent to vandals and burglars.

Customisable Options

Retractable grilles are available with several customisable options, including surface-mounted push locks on standard grilles, multi-point locking systems on insurance-approved grilles, and higher security hook locks as an additional extra. Not only do they provide enhanced security, but they can also reduce insurance premiums, making them a sound investment for your property.

Frequently Asked Questions

Retractable grilles are a type of security barrier that provide protection for doors and windows, while still allowing natural light and ventilation. These grilles are typically installed on the inside of buildings and can be pulled back or retracted when not in use, providing unobstructed views and access. They are commonly used in both residential and commercial settings as an effective deterrent against burglars and intruders. Retractable grilles are available in a variety of sizes, designs and finishes, making them a versatile and stylish security option that can be tailored to suit any décor.

Retractable grilles work by providing a physical barrier that can be extended or retracted as needed. They consist of a metal lattice that can slide along a track to open or close a space, such as a door or window.

When closed, the grilles create a robust barrier that is difficult to breach, making them a popular choice for security-conscious homeowners and businesses. The grilles can be locked into place to prevent unauthorized access, and their design allows natural light to pass through while maintaining a level of privacy.

Retractable grilles can be operated manually or electrically, depending on the model and the user’s preferences. Manual models typically require a key to lock and unlock the grille, while electrical models can be operated with the push of a button or a remote control.

Retractable grilles are a popular choice for businesses and homeowners looking for an extra layer of security for their windows and doors. One of the main benefits of retractable grilles is their ability to provide a high level of security while still allowing maximum visibility and natural light to enter the premises.

Retractable grilles are also highly versatile and can be fitted to a variety of different window and door sizes and configurations. They can be custom-designed to suit the specific needs of each property and are available in both standard and insurance-approved options.

In addition to their security benefits, retractable grilles are also very durable and low maintenance. They are typically made from high-quality materials, such as steel, which makes them resistant to corrosion and wear and tear. This means that they will provide long-lasting protection for your property.

Retractable grilles are also easy to operate, with many models featuring a smooth sliding mechanism that allows them to be easily opened and closed as needed. This makes them a convenient and user-friendly security option.

Retractable grilles are a versatile security solution that can be adapted to fit various types of windows and doors. There are several different types of retractable grilles available on the market, each with their own unique features and benefits.

One common type is the concertina grille, which folds away neatly when not in use and can be easily opened and closed as needed. These grilles are often used on windows, doors, and other openings that require a high level of security.

Another type of retractable grille is the mesh grille, which is made of a strong steel mesh that can withstand impact and prevent forced entry. Mesh grilles can be designed to blend in with the surrounding architecture, making them a popular choice for residential and commercial properties alike.

A third type of retractable grille is the sliding grille, which operates on a track and can be opened and closed horizontally. This type of grille is often used for larger openings such as patio doors or shop fronts, as it provides a high level of security while still allowing for a clear view of the outside.

Regardless of the type of retractable grille chosen, they all offer a number of benefits, including increased security, ease of use, and flexibility in terms of design and application.

Measuring for a retractable security grille is an important step in ensuring a proper fit and maximum security for your property. Here are some steps to follow when measuring for a retractable security grille:

  1. Measure the width of the opening: Measure the distance between the two sides of the opening where the grille will be installed. Be sure to take measurements at the top, middle, and bottom of the opening as it may not be perfectly square.
  2. Measure the height of the opening: Measure the distance from the top to the bottom of the opening where the grille will be installed. Again, take measurements at multiple points to account for any variations.
  3. Check for obstructions: Take note of any obstructions, such as light fixtures or switches, that may interfere with the installation of the grille. This will ensure that the grille can be installed without any issues.
  4. Determine the mounting surface: Decide on the type of mounting surface for the grille, whether it will be mounted inside or outside the opening, and whether it will be mounted to a wall or ceiling.
  5. Consult with our professionals: If you are unsure about the measurements or installation process, consult with one of our professional installers who can guide you through the process and provide expert advice on the best options for your property.

By following these steps and consulting with our professionals, you can ensure a proper fit and maximum security for your property.

Frequently Asked Questions

The word ‘Trellidor’ is actually the brand name of South African security barrier manufacturer Trellidor. The company manufactures steel and aluminium sliding trellis-style safety gates. These are fitted to doors and windows to protect people from intruders.
  • Double uprights. ‘Uprights’ are the vertical steel bars that run from the top to bottom track, and you’ll see them in pairs along the length of a Trellidor security gate. This is a strengthening feature.
  • The links that form part of the trellis pattern across a Trellidor gate link three uprights together.
  • U-shaped profiles. The vertical steel bars and the links that connect them are shaped into a ‘U’, making it easy to coat all surfaces against corrosion.
  • The unique, patented Trellidor lock is branded. The name ‘Trellidor’ is etched into the lock cylinder.
  • Trellidor gates have a single key and keyhole.
  • Trellidor gates have a T-shaped, low profile bottom track, designed to reduce the chances of tripping over the track and also to make it harder for criminals to pull the uprights off the track.
Custom-made sliding gates fitted by an expert technician instead give you far better protection. Rather contact a Trellidor franchise near you for gates that are fitted with tamper-proof fixings and the locks are designed to make it difficult for robbers to breakthrough.
  • Use a premium quality (salt-free) car wash liquid, mixed with water as per manufacturer’s directions and a soft cotton cloth to clean the entire unit.
  • Hard to reach areas may require the use of a soft nylon bristle brush such as a dishwashing brush.
  • Dry the unit with a soft cotton cloth or chamois.
  • Apply the Trellidor lubricating spray (available from your local franchise) to all moving parts, especially all hinge points inside the channel sections and into the top tracks.
  • Shake the can of lubricating spray well, apply to a clean cotton cloth and wipe the entire unit, or spray directly onto unit from a distance of about 20cm.
  • Wipe off the excess residue. This will form a protective barrier against both moisture and contamination of airborne pollutants.
  • A second application may be required if the unit has stood for too long without being lubricated and has become stiff, dry and difficult to operate.

Take special note of the following warnings:

Never use abrasive cleaners, detergent-based cleaners or solvent-based cleaners such as scouring agents, dishwashing liquids, washing powders, thinners etc as these could adversely affect the expected life of the sliding security gate.
Do not spray into the keyhole of the cylinder where the key fits!
Remember to read the warnings on the lubricating spray label as the product is highly flammable, must not be ingested and is irritating to eyes and skin.

Trellidor locks are patented designs that are fitted using specialist tools. These tools are not easily available at hardware stores, which is one of the safety features built into Trellidor gates.

You may need to change your lock under the following circumstances:

  • You’ve had an attempted break-in and the lock has been damaged.
  • If you have several sliding gates in your home, you may want to get your gates keyed-alike. This means that all your locks can be opened with the same key, instead of using different keys for each gate. Trellidor offers this option so that you don’t have to keep large bunches of keys around the home. The locks will have to be changed to do this.
  • If you’ve had a break-in it is advisable to change the locks. The home invaders may steal your keys and use them to get in again.
  • The same applies if you have dismissed employees that work at your home.
  • If you have moved into a new home that has sliding security gates, get the original manufacturer to change the locks. You never know who may have had access to the sliding gate keys.
  • If you keep your house keys on the same key ring as your car keys and have been hijacked. Change the sliding security gate locks to avoid the hijackers or accomplices breaking into your home.

In all these cases, you need to call in your local authorised Trellidor supplier to replace the locks for you. They will do it quickly and easily as they have the correct tools to do so.
