Door barriers, also known as door restrainers, are essential to any building project.

Designed with unique and specialised features, they play a crucial role in providing both functionality and protection.

One of the simplest yet effective ways to protect entry points to any building, door barriers are a key feature to consider to prevent damage and protect doorways of buildings in a multitude of environments. Do you know the benefits that each different type of door barrier can provide for your next project? With over 60 years of expertise, BOYCO are here to guide you with the best options to suit your next project needs…

Door Barriers with Catches

Featuring our unique die-cast catch mechanism, these door barriers feature an integrated catch and wall receiver providing a sleek yet functional solution for any environment. Commonly used in public or commercial spaces such as schools and medical centres, this door restrainer is ideal for entrances and exits which cover high-traffic areas needing protection from damage. Available in nine different colours of our Hot-Dip Nylon coating, you are sure to find a perfect match for your building’s aesthetic.

Door Barriers with Buffers

Created using our Hot-Dip Nylon Coating, the buffer built into the door barrier includes a unique ‘cane-detector’ to provide enhanced safety to those with visual impairments. Not only designed to provide safety to individuals, the included buffer also shields doors from potential wind damage, making them a practical and reliable choice for any project.

Door Barriers with Infill Panels

Recently used on our recent high-profile Coffee Store project, our infill panel option is designed with toughened glass for added safety and practicality around doorways. Particularly favoured by schools, offices or hospitality facilities, they’re another great way to prevent injuries to others by reducing the risk of individuals, particularly children, climbing through open spaces.

What Colours are BOYCO Door Barriers Available in?

With most of our range, you can either opt for one of our nine standard colours or select a stainless-steel finish.

We recommend that the colour and finish option you select suits the aesthetic of the environment. For example, we find that brighter colours such as yellow are perfect for primary schools, whilst you may prefer a more contemporary grey finish for high education buildings.

Stainless-steel offers a sleek look, and is often used in commercial spaces, office environments or on the outside of healthcare buildings. You can read our expert insights into colour theory, and selecting the perfect colour for your project here.

What makes BOYCO Door Barriers Different?

All our door barriers come with our 10-year guarantee, highlighting our market-leading manufacturing quality whilst also providing peace of mind for you and your customers.

If you’re opting for a non-stainless-steel finish, your door barrier will be coated in BOYCO’s hot-dip nylon.
