The CS13 Retractable Grille is manufactured to order, with a typical lead time of 6–8 weeks from order confirmation and final specification. This reflects the advanced engineering, reinforced construction, and rigorous quality controls required to meet LPS1175 SR3 and structural loading certifications.

Lead times may vary depending on project size, configuration, and installation complexity, particularly for large openings or infrastructure projects. Due to the specialist nature of this product, accurate timescales will always be confirmed at quotation stage to align with your project programme.

The CS13 Retractable Grille is a high-security, LPCB-certified SR3 system, designed for environments requiring maximum resistance to sustained attack and crowd loading performance. As a result, it sits at the top end of the retractable grille range, with pricing reflecting its advanced engineering, certification, and installation requirements.

• Opening Size: Larger spans significantly increase cost
• Configuration: Single sash, double sash, or fixed systems
• Structural Requirements: Installation into masonry or structural steel
• Crowd Load Compliance: Additional engineering for 5kN/m load resistance
• Finish: Standard powder coating vs bespoke RAL/BS colours
• Installation Complexity: High-security environments or restricted access

Installation Considerations

Due to its certified and structural nature, the CS13 requires:

• Installation in line with LPS1175 SR3 and structural testing standards
• Fixing into approved load-bearing substrates only
• Accurate alignment to maintain security and operational performance
• Potential coordination with structural engineers or main contractors

This results in higher installation costs compared to lower-rated systems.
