Metal Detector Equipment & Knife Arches

Acting as a quick and non-intrusive screening tool, a walk through metal detector provides a way to detect metallic objects. From preventing knife-related incidents to improving access control, this equipment plays a crucial role in protecting people and premises.
Knife Arches for Effective Screening
A walk through metal detector works using electromagnetic fields to detect metal objects on a person as they pass through. The system identifies both ferrous and non-ferrous metals, depending on sensitivity settings. It’s widely used at entrances where quick security checks are necessary, and often in combination with other screening tools and access control systems.
The term “metal detector” can refer to handheld or ground-scanning devices, but a walk through metal detector gate is designed for monitoring foot traffic in real time and alerting security personnel if something is detected.

Knife Arches: A Vital Security Feature
A knife arch is a type of walk through metal detector specifically designed to detect bladed items. These are increasingly being deployed in environments such as schools, public events, and transport hubs to reduce the risk of knife crime. These are commonly already seen in settings such as airports, courthouses and high-risk/security public buildings.
Why Knife Arches in Schools Are Crucial for Safety
Knife incidents in schools in the UK are a growing concern, prompting calls for increased preventative measures such as knife arches to support safeguarding efforts.
The presence of knife arches in schools serves as both a deterrent and a practical screening tool to detect knives and other prohibited items without disrupting school operations. These systems provide reassurance to pupils, parents, staff and the wider community while creating and promoting safe learning environments.

Supporting Martyn’s Law Compliance
With Martyn’s Law (Protect Duty) soon to be a legal requirement, venue operators must take practical steps to protect the public from terrorism and other security threats. Our metal detectors and knife arches play a key role in meeting these requirements by:
Providing visible deterrents to potential threats
