Security Fence Topper Types You May Choose

If you are looking for additional peace of mind for your property, taking anti-climb measures to existing fences or walls will be a practical and economical choice. Security fence topper ensures that no intruders can climb over the walls or fences. It will help to prevent the happening of criminal activities and protect your property effectively.

A relatively primitive type of security fence topper is broken glass. Several lines of chunk glass will be inserted into the wall top with sharp sides pointing up. However, the fragile glass is easy to break which consequently cuts its protective value. That’s why more and more metal made security fence toppers appear in the market.

Different Types of Security Fence Topper

Security Fence Topper No.1 - Anti-climb wall spike

Anti-climb wall spikes are also known as security wall spikes, anti-bird spikes, or defensive razor spikes. They are usually made of thin stainless steel plates or galvanized steel plates in the shape of spikes. Many clients may require a colorful polyester powder coating to make them appealing in look.

They are designed to be mounted on a wall or fixed along the top edge of fences to deter any intruders. According to different application scenarios, this kind of security fence topper is classified into small, medium, and big.

Generally, big and small-sized wall spikes are often used in the military while medium-sized are preferred for wall protection in gardens, factories, airports, etc. However, there’s no fixed rule. You are the final decision maker for what types of wall spikes to use and where to use them.
