We produce two main frame types for our steel door range, all fitted with weather seals and security pegs.

Rebate Frame

Our general purpose frame for fitting between walls, into steelwork, masonry or timber. Adjustable hinges are fitted as standard, with continuous hinges as an option. The integral concealed adjusting screws will accommodate up to a 10mm clearance per side in the structural opening, eliminating the use of loose packings. Many profile variants and sizes are available.

Type 3 Frame

A special purpose frame, often used for portable or sectional buildings. The frame depth is normally tailored to match the wall thickness. Also available as a two-part clamp frame.

The threshold is designed as an integral part of the doorset, giving additional strength to the frame; aiding weatherproofing and sound reduction, and providing a stable surface for lower locking points.

For general purpose industrial buildings, construction is normally of galvanised steel. For offices, shops and public buildings, aluminium or stainless steel is used for the aesthetic qualities. For food preparation areas or wet situations, stainless steel has the necessary hygienic and corrosion resistance properties.

For very heavy use, we can fit additional internal reinforcing. For severe duty use, such as forklift traffic, solid stainless steel gives the ultimate in strength.

Where no threshold is required for a level access, the doorset will be delivered with a temporary threshold which is removed after installation.

We recommend that external doorsets with no threshold should be fitted with an automatic drop seal, to minimise water ingress, draughts and noise. Dropseals may be surface mounted or concealed within the door bottom.

Locking Systems

Specifying particular locks will change the operation of a doorset. Points to be considered are:

  • Emergency requirements
  • Frequency of use
  • Security

We can advise on the correct locking equipment for a particular use, but in general:

  • Personnel doors are fitted with a standard mortice lock.
  • Doors that need more security, can have additional mortice dead locks or a multi-point locking system.
  • Escape doors to be used by members of the public need a full width panic bar.
  • Escape doors to be used only by internal staff and not by members of the public, may be fitted with either a push pad or mortice escape lock. For frequent use as a personnel door, a mortice escape lock is the preferred option.

Mortice locks

Mortice locks fit inside the door, and are available with several different functions
On a mortice escape lock, depressing the inside handle will override a locked cylinder or deadbolt. Standard locks and escape locks may be easily exchanged on site if escape functions are revised after installation.

Panic Bars and Push Pads

These units are surface mounted, have 1 to 3 locking points.


Europrofile lock cylinders are available in standard and drill-resistant, high security types. High security keys are not easily copied and can be useful to avoid unauthorised key duplication.
Various keying options are available - standard differ, keyed alike, master, suites etc.

Access control

Systems may be activated by various means, including card or proximity readers, keypads, microwave or infra-red sensors, biometric sensors, or just manual switches. To link with a building’s system, we can supply doorsets fitted with:

  • Electric handles
  • Electric strikes
  • Maglocks
  • Powered operators 

Units are available in 12V or 24V, AC or DC to suit most access control systems.

Doorsets may be fitted with sensors to provide open or closed position information to a central control room.


First impressions count. As the first part of a building to be touched, steel and glass door handles need to be selected with care and attention to detail. All of our door handles are carefully chosen for their functionality, style and durability. They convey a message of quality - feeling solid and reassuring in the hand.


Many of the door handles are available in a choice of materials: aluminium, brass, nylon or stainless steel, and may have a choice of finishes: brushed, satin or mirror polished.

Lever Handles

Lever handles are available with long backplates, or on round roses with a matching cylinder escutcheon.

Subject to a few limitations, our lever handles may be paired with most of the mortice locks, while the surface mounted locking systems have their own specific handles and outside operators.

Pull Handles

Our pull handles are all bolt-through for heavy duty use, with either a push plate to conceal the fixings of a single handle, or back to back fixings for a pair of handles. We offer a section of sizes, from 300mm to 1800mm, in straight, cranked, curved or angled styles.

Door Closers

Overhead closers are versatile and useful. All will close the door, to limit further access or maintain internal environments. Depending on the model chosen, they can also:

  • Control the opening and closing speed – useful in windy situations.
  • Restrict the door opening angle, to prevent damage to doors and the reveal corners.
  • Hold a door open - useful when carrying goods through.
  • Delay closing – helpful for parents with buggies or people with limited mobility.
  • Fire rated doors must be fitted with a self closing device so that the doorset will resist the spread of fire. If these doors need to be held open in normal use, we can fit electro-hydraulic closers linked to the building’s fire alarm system.

Surface mounted closers are available in several finishes, to complement the chosen colour scheme.

Concealed closers are useful in some situations:

  • Not visually intrusive – can promote a minimalist look
  • Will allow doors to be opened nearer to adjacent walls or other obstructions. The closer body does not protrude from the surface of a door, nor does its arm stick out.
  • Can be helpful in anti-ligature regimes.
  • Are less susceptible to vandalism.
Limit Stays

Adjustable telescopic limit stays are a budget alternative to closers. They can:

  • Restrict the door opening angle to prevent damage to doors and the reveal corners.
  • Be tightened to hold a door open.

Powered Operators

Powered operators are often fitted to main entrance doors to allow unimpeded entry and exit of pedestrians from a building. They can also be useful when:

  • Carrying goods through
  • Pushing trolleys through
  • Driving vehicles through
  • Linked to access control systems
Inward Opening Doors

Closers are usually mounted on the door leaf. On inward opening doors this can result in the closer body fouling the wall so you may need to allow extra clearance or a recess cut into the wall. 


We produce both made to measure and standard sizes. When ordering, please note that it is customary to allow a fitting clearance of 0 – 8mm on the width and 5 – 10mm on the height of a doorset.

When fitting to steelwork or timber, we normally allow 5mm clearance on the width and 5mm on the height of a doorset. When fitting to masonry, we increase the clearances to 8mm on the width and 8mm on the height, to compensate for slight variations in the structural opening.

In general, clearances should be kept tight on the width for a neat appearance, but on the height, more clearance is advisable to allow for the arc of movement as the doorset pivots towards vertical during installation.

We always advise that actual structural openings are measured, if possible after the floor has been laid. Please do not assume that structural openings will be constructed exactly to the size shown on the architect’s drawings.

Colours and Materials

Rimex stainless steels combine many remarkable textures, colours and patterns.
The texturing process work hardens the steel to increase its toughness. The material is suitable for exterior use, is difficult to damage, hides dents and scratches and is a deterrent to vandalism.

On satin and mirror finish material, a state of the art etching technique offers standard patterns, custom designs such as company logos, or even unique and original art to your own design.
