How its made

HIGHLY-SKILLED CRAFTSMEN

Our highly skilled craftsmen and technicians mill our stylish security door skins with the HOMAG 5 axis CNC router. Almost all of our panels are hand-sanded before we apply three coats of primer and two coats of your choice of paint or varnish. We’ll match the colours of our high-end security doors and windows with any sample.

MADE IN BRITAIN
Local Manufacturing

MADE IN BRITAIN

With state of the art protection in mind, our doors are proudly Made in Britain.

Step 1

Engineering

Our attention to detail completes the design process and transforms a simple piece of metal and wood into a work of art.

CNC wood milling
Step 2

CNC wood milling

With a world-class CNC milling machine from HOMAG, we can significantly expand our product's capabilities, performance, and output, all whilst maintaining our rigorous standards. It also maximises efficiency and reliability to fulfil any bespoke design or order for our customer's requests. An industry-leading range of processing areas accommodates all standard sheet sizes and an endless catalogue of CNC machine options available today. Our expert knowledge allows us to perfect the production details and offer advice on the best materials for your project.

CNC steel sheet processing
Step 3

CNC steel sheet processing

With manufacturing and computer technology developing rapidly, CNC machines can punch anything from simple circles or squares to more challenging geometric designs. All this can be done in a fraction of the time from the pre CNC era, offering considerable savings to you, the customer, and dramatically reducing our production lead times. Using our Prima Power punching machine, we can accommodate many projects once the design is approved. With the aid of CNC technology, punched components are produced within minutes. Our CAD Design Engineers onsite will use their years of experience to determine the best punch press option for your project and associated costs.

Bespoke joinery
Step 4

Bespoke joinery

Our skilled joiners and panel preparing team will ensure that every commission and item of joinery is made with precision and care. We use a variety of materials as Medite Tricoya, Okoume Wood, and solid or engineered plank woods. We can also procure the specialist services offered throughout our established network of collaborative partnerships, including metal workers, stonemasons, and upholsterers.

CNC press brake
Step 5

CNC press brake

Our computer numerically controlled (CNC) bending is a sheet metal folding process carried out by CNC press brakes. These machines can bend sheet metal from just a few mm in length to sections many metres long on the most prominent industrial machines. At our factory, we can CNC fold up to 3m long door profiles and bespoke components. CNC punching and CNC bending are the backbone of our manufacturing process, coupled with MIG welding. This combination allows the construction of virtually any project.

Hand preparation
Step 6

Hand preparation

The start of the spraying process begins with preparation. Before any items enter the spray booth, our dedicated and skilled preparation team carefully hand sands the MDF materials. An orbital sander is used for edge work and flat surfaces, which allows us to sand and prime components in optimal and consistent conditions, ready for painting.

Hand welding with MIG
Step 6

Hand welding with MIG

A MIG welded carcass serves as the main skeleton of our door and provides the base to attach our bespoke panel work. The ability to fuse various grades of advanced steels into a single component improves performance, safety, reduces unnecessary weight, and helps reduce overall production costs. Our highly qualified welding team welcome the challenge of working on your bespoke project and are proud to have fabricated thousands of bespoke and secure opening solutions for our valued clients.

Spray paint
Step 7

Spray paint

At Security Doors Factory Ltd., we have worked long and hard to establish ourselves as one of the leading spray painting facilities in the UK. Spray painting is one of the most complicated things to perfect in the wooden or cladded door making industry. Our high-end finishes require a dust-free, temperature and humidity controlled environment and can only be carried out on-site in our state of the art workshop. We hand-spray all of our doors in any RAL or designer colour of your choice. We take great care during every stage, from surface preparation right through to drying and polishing. So you can be assured that your doors are truly bespoke and will meet your exact requirements. In our spray booth, we use polyurethane paint for all MDF and plywood. Polyurethane paint is used for both priming and top coating and is a great protective layer for painted external doors as it cures and leaves a highly hard-wearing finish. Polyurethane is also more moisture resistant and can be used on vertical surfaces for doors, windows, and other humidity areas. High gloss finishes are also easier to achieve with polyurethane.

Powder coating
Step 9

Powder coating

Powder coating all of our metal door parts offers several advantages over conventional liquid coating methods. For example, we use zinc primers that prolong the application and lifespan of even our most specialised finishes in even the harshest of conditions, such as coastal locations or those subject to severe weather conditions. We have access to over 500 different powders and can also provide several finishes, including metallic, textured, antique, matt, satin and gloss. We can powder coat items up to 3 metres in length, 2.5 metres in height and 2 meters in width - with our factory not restricted by a project’s weight.

Assembly
Step 10

Assembly

At this sensitive point, we always take extreme care and expertise in the successful marriage of wood and steel, the newest high-tech locking devices, with bespoke handcrafted ancient furniture. At Security Doors Factory, we trust that a genuine manufacturer must combine the creative function of his work with technology, becoming an authentic leader in its field.
