Extendable Diamond Barrier HD – Heavy Duty Mobile Safety Barrier

The Extendable Diamond Barrier HD is a heavy-duty, mobile expanding safety barrier designed to quickly secure restricted areas, manage pedestrian access and improve safety in busy working environments.

Manufactured from strong yet lightweight powder-coated aluminium, this professional-grade barrier combines durability, high visibility and easy handling. Its expandable diamond design makes it ideal for temporary access control, construction sites, warehouses, railway maintenance and public events.

Key Features

• Heavy-duty aluminium construction – Strong, durable and lightweight powder-coated frame for long-lasting use.

• Expandable diamond design – Quickly extend or retract the barrier to suit different access points and restricted areas.

• Mobile and easy to position – Fitted with rubber castor wheels for convenient movement and reduced risk of surface damage.

• Lockable wheels – Integrated wheel brakes help keep the barrier securely positioned during use.

• High visibility – Designed to clearly identify restricted areas and improve awareness of potential hazards.

• Compact storage – The barrier folds down when not in use and features a secure latch to hold it in the closed position.

• Modular system – Multiple barriers can be connected using optional linking accessories to create longer continuous barriers.

• Suitable for indoor and outdoor use – A versatile solution for temporary site safety and pedestrian management.

Fast Deployment and Flexible Access Control

The Extendable Diamond Barrier HD can be deployed in seconds, making it particularly useful in environments where access restrictions frequently change.

Simply move the barrier into position, expand it to the required width and engage the wheel brakes.

Its retractable design allows it to be folded away quickly when access is no longer restricted, helping save valuable storage space.

For larger areas, multiple barriers can be joined together using compatible linking kits, providing a flexible and scalable safety solution.

Built for Demanding Environments

Unlike lightweight temporary barriers, the HD model features a reinforced aluminium construction designed for repeated use in commercial and industrial environments.

The powder-coated frame offers durability, while the rubber castor wheels make repositioning easier without unnecessarily marking or damaging floor surfaces.

The integrated locking mechanism keeps the barrier compact during transport and storage.

Typical Applications

• Construction sites – Restrict pedestrian access to hazardous working areas and temporary exclusion zones.

• Warehouses and logistics centres – Separate operational areas, maintenance zones and pedestrian routes.

• Railway maintenance – Establish temporary restricted areas during maintenance and inspection work.

• Factories and industrial facilities – Secure machinery, maintenance operations and temporary work zones.

• Shopping centres and public buildings – Temporarily close corridors, entrances or areas undergoing cleaning and maintenance.

• Events and festivals – Create flexible access restrictions and temporary pedestrian boundaries.

Product Specifications

Installation and Usage

No permanent installation is required for normal mobile use. The barrier can be moved into position, expanded and secured using its integrated wheel brakes.

For optimum stability and operation, we recommend using the barrier on a clean, smooth and level surface.

Optional linking and anchoring accessories are available separately for applications requiring additional barrier length or securing arrangements.

A Reusable Safety Solution

Manufactured primarily from durable aluminium, the Extendable Diamond Barrier HD is designed for repeated deployment across different projects and locations.

Its long service life, compact storage design and reusable construction make it a practical alternative to temporary single-use access restriction solutions.
