The initial stage of manufacturing a fire door begins long before any timber, steel, or hardware is cut or assembled. It starts with understanding the client's requirements and translating them into a compliant technical specification. One of our surveyors will visit the project site to gather information about the door's intended location and operating environment. During the survey, they typically assess: •Door opening dimensions (width, height, depth) •Wall construction (masonry, stud partition, concrete, etc.) •Fire compartmentation strategy •Traffic levels and intended use •Existing frame conditions (for replacements) •Accessibility requirements •Environmental factors such as moisture, temperature, and exposure •Security and acoustic requirements Measurements are taken carefully because fire doors must fit within strict tolerances to maintain their fire-resistance performance. The survey information is compared with project documentation, which may include: •Architectural drawings •Door schedules •Fire strategy reports •Building regulations requirements •Specifications from architects or consultants The manufacturer determines where each door is located within the building's fire compartmentation plan and what level of fire resistance is required (for example, FD30, FD60, depending on the project requirements). Once all information has been reviewed and approved, a formal manufacturing specification is generated. This document becomes the basis for production

The fire door starts with a door blank. The door leaf is the main body of the fire door. Unlike a standard internal door, it contains a dense fire-resistant core. The core slows heat transfer and helps maintain structural integrity during a fire. Hardwood lippings are bonded around the perimeter of the door. Functions: •Protect door edges from damage •Allow trimming within approved limits •Provide a solid fixing area •Improve durability Typical hardwoods include oak, beech, or maple. Fire doors contain intumescent seals fitted into grooves in either the door edge or frame. When exposed to heat: 1.The material expands. 2.Gaps between the door and frame are sealed. 3.Flames and hot gases are prevented from passing through. These seals can expand many times their original size. Many doors also include smoke seals. These are usually: •Brush seals •Blade seals They help restrict the movement of smoke before temperatures become high enough to activate intumescent materials. Common ratings: •FD30S •FD60S The "S" indicates smoke control capability. The frame is part of the fire-door assembly and is usually made from: •Hardwood •Softwood (where certified) •Steel The frame must be compatible with the tested door design. Gaps between frame and wall are filled with approved fire-stopping materials such as: •Mineral wool •Fire-resistant sealants •Fire-rated mastics Hinges Typically: •Three steel hinges •Fire-tested and CE/UKCA marked where applicable Locks and Latches Require: •Fire-rated lock cases •Intumescent protection where specified Door Closers Ensure the door returns to the closed position after opening. Panic Hardware Used on escape routes where required. Vision Panels and Fire-Rated Glass If glazing is required, special fire-resistant glass is used. Examples include: •Wired glass •Gel-filled fire glass •Multi-layer fire-resistant glazing The glass is installed using: •Fire-tested glazing beads •Intumescent glazing systems Ordinary glass would fail very quickly in a fire. Finishing After assembly, the door may receive: •Veneer finishing •Paint systems •Laminate coverings •Factory-applied coatings Finishes must comply with the certified fire-door design.

Once manufacturing and quality inspections have been completed, the fire door is prepared for dispatch. The door is checked against the project specification, labelled with its identification and certification details, and packaged to protect it from damage during transportation. Protective wrapping, corner protectors, and secured on pallets to prevent scratches, impacts, moisture ingress, or distortion. Before dispatch, the logistics team confirms: •Delivery address and site access arrangements •Delivery dates and times •Offloading requirements •Storage conditions available on site •Any project-specific handling instructions During transport, doors are stored suitable to avoid warping or damage. Delivery schedules are coordinated with the project's construction programme to ensure the doors arrive when required for installation. Upon arrival at site, the delivery is checked against the order documentation. Site personnel inspect the doors for any signs of transit damage and verify that the correct door types, quantities, fire ratings, and associated components have been received. The doors are then stored in a clean, dry, secure location, protected from weather exposure and construction activities until installation. A reliable delivery process ensures that fire doors reach site in the correct condition, fully traceable, and ready for installation, helping to maintain programme deadlines, product quality, and compliance with fire safety requirements.

Our quality fire door installation is the process of fitting a fire door assembly in accordance with certification requirements, and relevant building regulations. Correct installation is critical because even a certified fire door can fail to perform as intended if it is installed incorrectly. Before installation begins, our installer verifies that the door, frame, hardware, seals, and glazing match the project specification and certification requirements. The opening is checked to ensure it is suitable for the fire door assembly and that the surrounding wall construction is compatible with the tested system. Fire safety procedures are followed consistently, keeping escape routes clear and maintaining the integrity of fire compartmentation throughout the installation process. Once installation is complete, the door is inspected and tested to confirm it performs correctly.
