Home Security: Why the Trellis Gate is One of the Most Useful Security Tools

A Trellis gate and window guards are manufactured to the highest standards to ensure the safety, security and protection of your family, home and valuables. Trellis gates and doors usually have two locks: 1 slam lock and 1 manual hook lock. Security gates with slam locks enable quick securing of access points to your home or business, but also allows for quick exits in case of emergency. The manual hook lock is secured with the key and adds an extra level of security to trellis gates.

We pride ourselves in delivering the best and strongest internal steel swing gates and doors in Johannesburg.

With the Trellis gate, one key fits all, by fitting multiple Trellis doors and sliding window guards which use the same key, the manufacturers make for easy access and convenience for any buyer.

Most Trellis Slam Lock doors are made from light weight A-Grade steel which ensures maximum strength and protection. No plastics are used in the manufacture process to ensure that the Trellis gate have exceptional stability. Galvanised twin steel legs improve aesthetics while providing extra strength and to prevent tampering with the roller mechanism. The galvanised bottom track is durable and ensures smooth sliding of the Trellis door.

Trellis doors are made-to-measure and professionally installed for perfect fit for increased protection. The durable, easy to clean finish of the powder coated Trellis gate is chip resistant and low maintenance which means that your security gate will both work well, and look good.

Providing a great deterrent against burglary, Trellis gates are the first choice for many types of customers; from retailers, households, supermarkets, office buildings and warehouses, dentists, doctors and hospitals.

tonicdorSo, whether you need a pair of gates for the entrance to your property, or a simple side gate, Trellis gates have a range that provide a solution to all needs and requirements. Even if you have a certain design in mind, or wish to build something original, many manufacturers also allow this. Gates can be made to a client’s specific needs; they can be simple or decorative. Nonetheless, all of these gates work the same: they protect you, your family and your valuables in all emergencies.

Burglar Proofing – What you need to Know.

Many homeowners of today want and need a home security solution that goes beyond monitoring a home’s perimeter for possible intruders. In some situations, window and door security bars make perimeter security plain, simple and affordable. Security bars, also called burglar bars or burglar proofing, are designed to be mounted with tamper-resistant fasteners and to discourage intruders. Most of these security bars are constructed of solid steel. But let’s face it: intruders intent on accessing your home will be expert at bypassing burglars bars or will simply enter another way.


So, what do you choose: burglar proofing or a home security system? Make sure you compare prices and products thoroughly. Security bars will not solve your security problems: steel window security bars offer protection for your home’s perimeter, but not for the interior of your home. Even though security bars may be a lot more affordable than a security system, remember that its protection capabilities are limited.

Burglar proofing come in standard and custom window sizes and in a variety of styles, textures, designs and colours. You will be able to find stylish, suitable burglar bars suited to your home and its style and design. Security bars are also fairly easy to install and can be done by almost anyone; making adding an alternative or addition security measure to your home so much easier.

Even though burglar proofing is one of the most common security measures taken by millions of people all over the world; it also has a negative side to it. A window that has a burglar bar installed over it, may cause a lot of trouble in the event that a fire should break- out inside your home. The burglar bars may make it extremely difficult, or even impossible to escape the fire, which could have fatal consequences.

When searching for a home security system or measure for your home, there is a lot that needs to be taken into account: you have to look at both the pros and the cons of the system and decide based on it. Nevertheless, there are so many systems to choose from, I am certain you will find the perfect one.
