HAG Ltd. have been providing quality bespoke steel doors, manufactured to suit specific site requirements, to companies in the UK and across the world for over 30 years. We know it can be difficult to find all the information necessary to choose the right doors for your premises, so we’ve put together this Complete Guide steel doors to help make the process easier.
2. What are Steel Doors?
The installation of a steel door product provides the ultimate in protection. Intruders will not be able to breach the steel door or framework with the same ease as a traditional timber door.
Locking devices and hardware incorporated in the HAG steel door system are also designed specifically to withstand such attacks and, with the additional benefits of fire protection, acoustic and thermal insulation make it the product of choice for today’s specifiers.
There does not need to be a compromise between style, security and energy efficiency for your property. As well as maintaining a robust exterior appearance, the range of steel doors can provide everything the modern building requires, such as sound and heat-loss reduction.
3. The components that make up a doorset
There are many components that make up the design of a steel doorset and work together to provide the best possible security and keep your property safe from damage or ingress.
The door frame is composed of extruded galvanised steel of at least 1.5 mm thickness.
The door leaf is pressed from galvanised steel of at least 0.9 mm thickness.
The type of infill depends on the specification of the door – for instance, thermal loss prevention would require a dense mineral wool, whilst heightened security doors may have a solid hardwood core or a lattice-work of steel plates. Entry-level door sets always have an infill of dense cardboard in a honeycomb formation, this provides a good level of insulation and sound attenuation.
The finishing consists of polyester powder, which is applied to the external surface of the door. It gives the door a strong yet aesthetically attractive finish, which is typically applied to home appliances and office furniture. However, for those doors that are subjected to the worst that weather can offer (transformer stations, seafront environments etc.) then marine-grade coatings can be employed.
4. The benefits of installing steel doors
Steel based structure in a steel frame.
Cheaper than aluminium or timber for equal security or fire resistance.
Sound and heat containment
Use of mineral wools can limit heat loss and noise transfer.
The range of additional features in the market allows designers to combine aesthetic appeal with practicality.
All of our steel doors, steel security doors, external steel doors and steel door sets are made bespoke to your project using high quality galvanised steel.
There are a number of variations to the standard HAG steel door that will benefit site-specific conditions, including the type of locking, door hardware, colour, vision panels and louvred ventilation.
When specifying a steel door for a project it’s important to consider the following:
Width and height of opening
Frequency of use
Features of operation
Head room requirements
It is important to make sure your doors are regularly serviced. Here are some of the checks that should be made regularly to ensure the safe operation of your steel door and prolong the life of the product.
Check all hinges for loose attaching screws, hinge pin wear or other notable defects. The door should always swing freely and smoothly without obstruction from the opened to latched (when latching device is used) position.
Lock sets, panic devices, fire exit hardware
Check all lock sets for loose attaching screws, latch wear or other notable defects. The door should always latch freely and smoothly without obstruction.
The strike plate should be firmly attached to the frame or inactive leaf of a pair of doors.
Check all closing devices for loose attaching screws, linkage arm and pin wear, fluid leakage or other notable defects.
Check all flush bolts for loose attaching screws, rod bolt adjustment and strike plate (on both door and frame if so equipped) attachment.
The glazing material should be checked for cracks and/or missing pieces of glazing.
Door and frame finish
A general visual inspection of the door and frame finish should be periodically conducted.
Fire rated and/or smoke control assemblies are specified and installed to meet “safety to life code requirements.”
Gasketing / weather-stripping
A visual and operational inspection is periodically necessary for gaskets and weather strips such as perimeter and threshold seals.
7. Safety Standards for Steel Doors
Security of the HAG steel door range is compliant with BS EN 1627:2011(the standard for burglar resistance of pedestrian door sets, windows, curtain walling, grilles and shutters) and/orPAS 24:2016 (the standard for enhanced security performance requirements for door assemblies).
Considerations in relation to fire.
Taken together all these components make up a whole system called a “doorset”. BS EN 12519 defines a doorset as “supplied complete with all essential parts from a single source and for which the main intended use is the access of pedestrians.”
Following the tragedy of Grenfell Tower in June 2017, the DHF / Secured by Design / Fire Industry Association published A Guide for Selecting Flat Entrance Doorsets (PDF download) HAG recommends that all specifiers read this. This makes the point that there is no conflict between fire and security with Building Regulations ADB (fire) and ADQ (security) carrying equal weight with neither taking precedence over the other. It explains why only factory produced doorsets can meet both ADB and ADQ.
HAG recommends that specifiers seek approval of the ‘Responsible Person’ as defined by Fire Safety Order (FSO) 2005 to confirm that the fire doorset meets the building’s fire safety requirements
Electro-galvanised steel, or zintec, is the industry norm with stainless steel grades 316 or 304 available for those conditions that require the extra weather resistance properties they provide.
Galvanised steel is grade S275 mild steel sheet that has been galvanised through a process called electrolysis. This is applied at point of manufacture and is therefore part of the structural make-up of the material, as opposed to a post manufacturing additive, such as hot-dip galvanising.
When external prime paint is applied, galvanized steel provides high quality resistance to corrosion and rusting. SDI (Steel Door Institute) recommends use of the A Series specification of A40 or A60 for primer adhesion. The A60 specification is considered better than the A40 specification with respect to rust protection. However, SDI does not advocate the use of G-series due to its lower quality primer adhesion attributes.
Where doors have been fire-rated, such clearances are subject to regulation under NFPA 80, “Fire Doors & Other Opening Protectives”. The clearance between the door and frame must occupy a space of at most 1/8″. Clearances between the adjacent edges of two doors must be 3/16″. Clearance from the lowest point of the door to the lowest point of the frame must not exceed 3/4″. Clearance between the door face and the stop must be 1/16″.
Among the factors that make up the cost of the door is the location. This informs the material quality and finish and security level, which in turn drives the specification of ironmongery and hardware.
A doorset is a whole door system. It includes the door leaf, door frame, glazing, seals and intumescents, hinges, door furniture, finish, signage and door closer mechanism. It is defined by BS EN 12519 as “supplied complete with all essential parts from a single source”.
A doorset is designed and tested as one unit by the manufacturer. It is this doorset that is certified to the appropriate standards and issued with a certificate of conformance. Because a doorset is manufactured in a factory, it can be produced to tight tolerances under high quality assurance standards and rigorously tested prior to delivery to site.
In the door industry, the term ‘door’ is frequently used as shorthand for a ‘doorset’.
