Flag Posts for Roller Shutters: Enhanced Support and Secure Installation

When specifying roller shutters, structural support and installation integrity are just as important as the curtain and control systems. One key component that contributes to both is the flag post. At HVP Security Shutters, we ensure every installation is robust and reliable by utilising flag posts where required, providing extra strength and a seamless finish.

What Is a Flag Post?

A flag post is a structural feature used in roller shutter installations to reinforce the assembly and facilitate secure fixing to the building. The term “flag post” refers to the distinctive appearance created when the cheek plate (the side plate that supports the shutter barrel) is welded to a vertical angle or directly to the top of the guide rail.

Construction and Function

Cheek Plate Integration: The cheek plate is either welded to a vertical angle or directly to the top of the shutter guide, forming a strong, continuous component known as the flag post.

Structural Support: The vertical angle of the flag post is firmly secured to the building’s structure—such as a wall or supporting column. This additional anchoring provides enhanced stability, particularly for larger or heavier shutters.

Installation Aid: By tying the shutter assembly directly into the building, the flag post not only strengthens the installation but also makes alignment and fitting more straightforward and precise.

Key Benefits of Flag Posts

Increased Strength: The flag post construction distributes the weight and operational forces of the shutter more evenly, reducing stress on fixings and prolonging the lifespan of the installation.

Improved Security: A securely anchored flag post makes it more difficult for intruders to force or dislodge the shutter, enhancing the overall security of your premises.

Neat Appearance: The flag post creates a clean, professional finish by integrating the cheek plate and guide rail, resulting in a streamlined look that complements any building façade.

Versatility: Suitable for a wide range of roller shutter types and sizes, flag posts are particularly beneficial for installations where additional lateral support is required.

Flag posts are commonly specified for:

Large commercial and industrial shutters

Wide-span openings requiring extra support

Installations where the building structure offers limited fixing points

Sites demanding the highest levels of security and durability
