Compliance & Certification

Fire doors must be fully traceable and supported by valid test evidence. All our products are backed by third-party certification and supplied as part of a compliant, tested system, not individual components.

Installation Guidance

Correct installation is essential to achieving fire performance. We provide technical guidance to ensure your door is installed in line with tested evidence, BS standards, and manufacturer requirements.

Delivery & Lead Times

Lead times vary depending on specification, finish, and configuration. We provide clear timelines and updates to support project planning and avoid delays on site.

Fire Doors are a System, not just a Door Leaf.

Compliance is achieved through correct specification, compatible components, and tested assemblies. Incorrect decisions at specification stage often lead to failed inspections, delays, and costly rework. Do not gamble with safety.

Anatomy of a Fire Door System

Every component affects compliance.
Understand how components must work together
as a tested, certified assembly, not a mix of parts.
