Sliding Security Gates

Sliding security gates are robust, metal gates that slide open and closed along a track. They provide a highly visible layer of protection against intruders for homes, businesses, and industrial properties. They are commonly used for doors, windows, storefronts, and entryways, offering both security and convenience.

Sliding security gates play a crucial role in safeguarding people and property. When professionally installed in an opening, a closed and locked sliding security gate effectively blocks unauthorised access into the building through that opening.

Well-made sliding security gates are easy to use, long-lasting and cost-effective. They are strong under attack and an excellent deterrent to criminals. Trellidor retractable security gates have been best-sellers for decades because we do not compromise on the strength of our security barriers.

Trellidor sliding security gates are made from a tough, double-trellis construction. Each gate is fitted with a unique, tamper-proof lock. Every Trellidor expanding steel or aluminium gate is made-to-measure for a perfect fit in doorways, windows, passages, patios, hatches and most other openings.

Where can Security Gates be used?

Security gates can be used in various settings to enhance safety and security. Here are some common locations where security gates are often installed:

Security gates are frequently used in residential settings, including single-family homes, townhouses, and apartments. They can be installed at the entrance of the property, passages, hatches, windows or specific areas like patio enclosures.

Security gates are utilised in commercial establishments such as office buildings, retail stores, warehouses, and factories. They can secure entrances, and restricted areas to prevent unauthorised access and protect valuable assets.

Schools, colleges, and universities often implement security gates to control access to the campus. They are installed at main entrances, or specific buildings to ensure the safety of students, staff, and facilities.

Hospitals, clinics, and medical centers employ security gates to regulate entry into sensitive areas like emergency departments or operating rooms. They contribute to patient privacy, staff safety, and protection of medical equipment.

Shopping malls, retail complexes, and stores often use security gates to secure storefronts and protect merchandise. They help deter theft, prevent after-hours break-ins, and maintain a secure shopping environment.

When to use Security Gates

RESIDENTIAL PROPERTIES

Security gates are commonly used in residential properties to protect homes and ensure the safety of occupants. They are particularly beneficial when in areas with higher crime rates, properties located in secluded areas, or homes with valuable assets.

COMMERCIAL PROPERTIES

Businesses, including offices, retail stores, warehouses, and industrial facilities, can benefit from security gates. They help when needing to control access, prevent unauthorised entry, and protect valuable assets, equipment, and sensitive information.

HIGH-CRIME AREAS

Security gates are particularly relevant in locations or neighbourhoods with a higher incidence of crime. If an area has a history of burglaries, break-ins, or vandalism, security gates can provide an added layer of protection to deter potential intruders.

NIGHT TIME OR AFTER-HOURS

Security gates are commonly used in situations where properties or facilities are unattended during nighttime or after regular operating hours. By securing entry points with security gates, it becomes more challenging for unauthorised individuals to enter the premises during vulnerable times.

EMERGENCY OR LOCKDOWN SCENARIOS

In emergency situations, such as a break-in, or other crises, security gates may be activated to limit access or control movement within a property. They help maintain safety, prevent unauthorised entry or exit, and enable effective emergency response.

HOLIDAY HOMES OR SEASONAL RESIDENCES

Homes that are unoccupied for long periods of time are extremely vulnerable to a break-in and theft. They can be secured and protected with locked sliding gates on all doors and windows.

PRODUCT COMPARISON

Retractable VS Fixed Security
for your Windows

Retractable security gates are not just for doorways. They can be fitted to protect windows as an alternative to fixed burglar bars. Window security barriers that can slide open as needed offer several advantages. 

THE DIFFERENCE BETWEEN RETRACTABLE AND FIXED SECURITY FOR WINDOWS

Burglar proofing for windows usually consists of permanently fixed bars across the part of the window that opens up for fresh air. What is less well known is that sliding security gates for doors work equally well as window protection and have some unique advantages. Here are the differences between the two types to help you make the right choice for your home. READ MORE

Steel vs. Aluminium Retractable Security Gates - Which is Right for You

Retractable security gates are a practical, popular, affordable form of protection for doors and windows. They can be manufactured from either steel or aluminium and often look very similar. So, what is the difference between the two and which one is right for you?

THE DIFFERENCE BETWEEN STEEL AND ALUMINIUM

When comparing steel and aluminium retractable security gates, the four factors that are usually considered are strength, corrosion resistance, weight, and cost. We’ll look at each of these points in turn.

The difficulty in making a comparison between steel and aluminium is that all factors have many variables within them. For instance, the cost of both steel and aluminium varies constantly, depending on world demand and local tariffs. READ MORE

Retractable Security Gates VS Roller Shutters

Retractable security gates slide from side to side by hand. They are locked using a key with a dead lock or slammed closed with a slam lock. Retractable gates have a bottom track for extra strength and easy sliding. You can see through the gates when they are closed and locked.  

By contrast, roller shutters glide up and down inside side guides. They are automated and operated at the touch of a button. They do not need a bottom track. You can’t see through locked down shutters unless some of the solid slats have been replaced with punched viewing panels.

Retractable security gates and roller shutters both provide excellent protection so to help decide which is best for you. READ MORE

SLAMLOCK VS. DEADLOCK SECURITY GATES

Difference Between Slam Lock and Dead Lock Security Gates

Traditional Trellidor sliding security gates are fitted with either a deadlock or a slamlock, depending on the model and customer preference.

THE DIFFERENCE BETWEEN THEM IS:

  • Deadlock – slide the gate closed by hand and turn the key in the lock.
  • Slamlock – slam the gate closed by hand to lock it automatically.

Both lock types engage several locking points within the lock stile for added security and strength under attack. Our computer-cut keys add another layer of protection. Each key has a unique code to help prevent unauthorised duplication of keys.

A sliding security gate fitted with a dead lock gate requires a key to lock it when the trellis gate is closed. These locks were invented by Jeremiah Chubb in England in the 1800’s. The Chubb company is known for its safes and locks. Well-made dead locks are usually strong and robust when attacked.

A sliding security gate fitted with a slam lock gate automatically locks when you slam the trellis gate shut. The concept originated with the Yale lock, invented in the late 1800’s in America. It is a convenient locking system but is not always the strongest type of burglar gate lock when attacked.
