1.8m High AcoustiGuard® SR1 (A1) LPS 1175 Steel Post Kit

1.8m High AcoustiGuard® SR1 (A1) LPS 1175 Post Kit

This Post Kit provides the essential structural foundation for the 1.8m High AcoustiGuard® SR1 (A1) LPS 1175 Acoustic Fencing system. Engineered to be more than just a support, this post is a critical component in a certified security and acoustic barrier, designed to deliver uncompromising stability, security, and longevity. Each post is manufactured to precise specifications to perfectly integrate with the 1.8m AcoustiGuard® panels, ensuring the entire system performs as a cohesive unit. The strength and durability of this post kit are paramount to achieving the fence's certified ratings for both security and structural performance, providing the robust backbone needed to withstand physical challenges and environmental forces for decades. This kit includes a single, heavy-duty steel post and the necessary fixings, forming the fundamental building block for each 2.42m section of your high-performance fence line.

The Role of the Post in the SR1 Certified System

While the acoustic panels form the visible barrier, this RSJ post is the anchor that guarantees the system's integrity, playing an indispensable role in its LPS 1175 SR1 (A1) security certification. The SR1 rating confirms that the complete fencing system can resist a sustained attack from an opportunistic intruder using common hand tools. The post's immense strength ensures that the panels cannot be simply pushed over, bent, or otherwise compromised by brute force. Its Rolled Steel Joist (RSJ) profile, also known as an I-beam, is engineered for exceptional resistance to bending forces along its primary axis, making it incredibly difficult to deform. This inherent strength is the reason it is specified for this high-security application. Furthermore, the post’s design allows the acoustic panels to be slotted in and securely fastened, preventing them from being lifted out or removed—a common point of failure in lesser systems. Achieving the full security rating is critically dependent on the correct installation of these posts, which requires them to be embedded deep into the ground to create a monolithic structure that provides a truly formidable deterrent to unauthorised access.

Superior Construction and Materials

Every component of this post kit is selected for maximum performance and service life, ensuring the long-term value and reliability of your investment.

• Post Specification: The post is a heavy-duty RSJ (Rolled Steel Joist) with a cross-section of 127 x 76mm and an overall length of 2700mm. This specific size is engineered to provide the optimal balance of strength and stability for the 1.8m high fencing system, ensuring it can handle design wind loads and resist physical attacks without failure.
• Finish and Durability: To guarantee protection against the elements, each post is Galvanised Steel, finished in strict accordance with the ISO 1461 manufacturing standard. This process involves hot-dip galvanising, where the entire steel post is submerged in a bath of molten zinc. This creates a thick, metallurgically bonded coating that covers every surface, corner, and edge, offering superior corrosion resistance compared to standard paint or electroplating. This finish ensures the structural core of your fence is protected from rust and degradation, providing decades of maintenance-free service.

Installation and Fixings

The performance of the AcoustiGuard® system is intrinsically linked to the correct installation of its posts. This kit is designed for a professional "Dig In" method to ensure maximum stability and security. The substantial 2700mm length of the post is designed to be installed 900mm in-ground, leaving a full 1800mm above ground to match the system height. This deep embedment anchors the post firmly, making it capable of withstanding significant lateral forces. This kit also includes the specified M8 x 100mm Flange Hex Head Wood screws. These essential fixings are used to securely fasten the horizontal timber rails of the acoustic panels directly to the steel post. This crucial step locks the panel into the post's channel, preventing it from being lifted or forced out and completing the integrated, secure perimeter. The system's design is also versatile, allowing for the creation of corners at any angle while maintaining SR1 compliance simply by installing two posts adjacently.
