- Fire and weather resistance: Steel provides natural fire resistance and, with suitable hardware and seals, ensures excellent protection from wind, rain, and temperature extremes.
Legal Requirement & Compliance
Installation of emergency fire exit doors is a legal requirement in the UK for any building regularly occupied by more than five people, and for virtually any premises used by the public during operational hours. Correctly specified exit doors are fundamental to safe evacuation strategies, aid compliance with fire safety legislation, and are frequently scrutinised during safety inspections.
- Doors must always be clearly marked and unobstructed, with easy access and clear signage indicating their location.
- Escape doors should open easily in the direction of exit and be free from internal locking mechanisms when in use.
- Regular maintenance and checks are essential to ensure escape routes remain effective and compliant.
Outa-Dor Exit steel doorsets offer the ideal solution—delivering certified performance, unrivalled durability, and long-term security, making them the preferred choice for modern fire safety compliance in all building types.

InstallationInstallation Guide: Robust Steel Doorsets
Robust steel doorsets are engineered with one clear goal: to be the easiest and fastest steel doors to install on the market. Whether you are fitting a single personnel door or a large double fire exit, our "Single Fix" design and adjustable frame system remove the complexity of traditional on-site joinery.
Delivered for Speed
To minimise site time and disruption, we supply our doorsets in the most installer-friendly format possible:
- Single Doors: Delivered fully assembled. The leaf is pre-hung in the frame with hardware (locks, panic bars, closers) factory-fitted and tested. Simply unwrap, position, and fix.
- Double Doors: For ease of manual handling, larger double doorsets may be supplied with the leaves separate from the frame. However, the frame is pre-prepared with all hinge points and striker plates for rapid on-site assembly.
The "Easy-Fit" Adjustable System
Structural openings are rarely perfect. All Robust doorsets feature a unique built-in adjustment system that handles site imperfections without the need for fiddly packers or shims.
1. Adjustable Fixing Feet
Each jamb is fitted with 4 adjustable fixing feet (8 per single door, 8-12 per double). These allow you to:
- Level the frame quickly using a 12mm hex key (supplied).
- Wind the feet out to grip the structural reveal securely, holding the frame in place while you check for plumb.
- Create a rock-solid fixing point without distorting the frame profile.
2. Variable Sub-Frame
The steel sub-frame features a "C" section tolerance channel that accommodates wall variations of -0mm to +30mm. This ensures:
- If your brickwork is uneven or the opening is slightly tapered, the frame expands to fill the gap.
- You achieve a continuous, secure fixing into the substrate without large, unsightly gaps to seal.
General Installation Steps
Step 1: Positioning
- Single Doors: Place the fully assembled unit into the structural opening.
- Double Doors: Assemble the frame (if supplied in parts) and position it in the opening first. Ensure the header is level before hanging the leaves.
Step 2: Adjustment & Levelling
- Use the 12mm hex key to wind out the adjustable feet until they grip the wall.
- Critical Check: Ensure the hinge jambs are perfectly plumb (vertical) in both planes using a long spirit level. If the frame is twisted, the door will not latch correctly.
- For double doors, ensure the frame header is perfectly level to prevent the leaves from misaligning at the meeting point.
Step 3: Fixing
- Drill through the centre of the adjustable feet into the masonry or steelwork.
- Secure with appropriate fixings (e.g., 100mm x 10mm concrete bolts or heavy-duty tech screws).
- Test: Open and close the door(s) to check for smooth operation and correct latching before final tightening.
Step 4: Sealing
- Apply a fire-rated silicone or intumescent mastic around the entire perimeter of the frame (internal and external) to ensure fire and weather integrity.
- If a threshold is fitted, ensure it is bedded on sealant to prevent water ingress.
Handling Advice
- Weight Warning: Steel doors are heavy. A single leaf can weigh 50kg - 80kg.
- Single Doors: Use a mechanical lifter or a two-person team.
- Double Doors: We strongly recommend separating the leaves from the frame before moving to the installation point to reduce lifting weight.
- Storage: Always store doorsets upright on timber bearers in a dry, covered area. Never lay them flat on uneven ground or expose them to rain before installation.

MeasureHow to Measure for Your Robust Steel Doorset
Getting the measurements right is critical for a smooth installation. Please follow this guide carefully to determine the correct ordering size for your Robust Outa-Dor. Remember: we manufacture to the exact dimensions you order, with no automatic tolerances deducted.
1. Measure the Structural Opening
Measure the raw aperture (brick-to-brick) where the door will be installed. Do not measure the existing frame.
- Width: Measure at the Top, Middle, and Bottom of the opening. Record the smallest dimension.
- Height: Measure at the Left and Right sides from the lintel to the finished floor level. Record the smallest dimension.
- Squareness: Check the diagonals (corner to corner) to see if the opening is square.
2. Calculate Your Ordering Size
The ordering size is the OVERALL size of the complete doorset unit (including the door leaf, frame, and threshold).
- Width Calculation: Take your smallest structural width and deduct your fitting tolerance (e.g., 10mm total).
- Height Calculation: Take your smallest structural height and deduct your fitting tolerance (e.g., 10mm total).
Example:
If your structural opening is 1000mm (W) x 2100mm (H):
Subtract 10mm from the width (5mm each side) → Order Width: 990mm
Subtract 10mm from the height (5mm top + 5mm bottom) → Order Height: 2090mm
The "Outa-Dor" Advantage: Built-in Tolerance
One of the key benefits of the Robust Outa-Dor is its unique adjustable fixing frame.
- Variable Sub-Frame: The frame design includes a variable "C" section that can accommodate up to 30mm of tolerance (+0mm / +30mm).
- Why this matters: If your brickwork is uneven or the opening isn't perfectly square, the frame can expand to fill the gaps. This makes the Outa-Dor significantly more forgiving to install than standard fixed-frame steel doors.
Important Reminders
- Metric Only: Please provide all measurements in millimetres (mm) to ensure accuracy.
- Check the Drawing: We will always create a technical drawing based on your ordering dimensions. This will be sent to you for final approval before manufacturing begins.
- Include the Threshold: Remember that the "Overall Height" includes the threshold. If you are recessing the threshold into the floor, you must account for this in your measurements.
Please refer to the diagram below for a visual guide on where to take your measurements.
