How it’s Made
The Art of Security Door Manufacturing
At Security Doors Factory, we combine precision engineering and expert craftsmanship to create bespoke security doors tailored to any design. Each door is built to the highest standards, ensuring exceptional strength, durability, and aesthetics.
From raw materials to the final installation, every step in our process is carefully executed to deliver uncompromising security without sacrificing style. Explore how our doors are made and see the craftsmanship behind every detail.
Precision Engineering & Design
Every bespoke security door begins with meticulous planning and design. Our engineering team translates the client’s vision into detailed 3D models, ensuring every specification, feature, and aesthetic detail is accounted for. Using advanced CAD software, these designs are refined and optimized before being sent to our CNC machinery, where raw metal and wood are transformed into precision-cut components – the first step in crafting a door that seamlessly blends security, functionality, and design excellence.
CNC Wood Milling
Equipped with a state-of-the-art HOMAG CNC milling machines, we enhance our product capabilities, precision, and efficiency while upholding the highest standards.
This advanced technology ensures optimal reliability and performance, allowing us to fulfil any bespoke design or custom order with exceptional accuracy. Its versatile processing range accommodates all standard sheet sizes, providing limitless design possibilities. Combined with our expert craftsmanship, we fine-tune every production detail and offer tailored guidance on the best materials for your project.
CNC Steel Processing
With rapid advancements in manufacturing and computer technology, CNC machines can effortlessly punch anything from simple shapes to complex geometric designs in a fraction of the time compared to pre-CNC methods. This not only reduces production lead times but also offers cost savings for our customers. Our Prima Power punching machines allows us to efficiently handle multiple projects once designs are approved, producing precision-punched components within minutes. Backed by onsite CAD Design engineers, we ensure the optimal punch press solution for your project, balancing efficiency, quality, and cost-effectiveness.
CNC Press Brake
Our CNC bending process, performed using precision-controlled press brakes, allows us to fold sheet metal components from just a few millimeters to several meters in length. At our factory, we can CNC fold door profiles and bespoke components up to 3 meters long, ensuring accuracy and consistency. CNC punching and bending, combined with MIG welding, form the foundation of our manufacturing process, enabling the construction of virtually any custom project with strength, precision, and efficiency.
MIG Hand Welding
The MIG-welded carcass forms the structural backbone of our doors, providing a robust and secure foundation for attaching bespoke panel work. By fusing various grades of advanced steel into a single component, we enhance performance, safety, and durability while optimizing weight and reducing production costs. Our expert welding team, with years of experience, takes pride in fabricating thousands of custom, high-security opening solutions, ensuring precision and reliability in every project.
Bespoke Joinery
Our skilled joiners and panel preparation team meticulously craft each commission with precision and care, ensuring the highest quality finish. We work with a range of premium materials, including Medite Tricoya, Okoume wood, and solid or engineered plank woods, tailored to meet project specifications. Additionally, we leverage our trusted network of expert partners, including metalworkers, stonemasons, and upholsterers, to incorporate specialist craftsmanship into our bespoke designs.
Hand Preparation
The spraying process begins with meticulous preparation. Before entering the spray booth, our skilled preparation team carefully hand-sands MDF materials to ensure a flawless surface. Using orbital sanders for edges and flat surfaces, we achieve optimal smoothness and consistency, creating the perfect foundation for priming and painting under controlled conditions.
Spray paint
We have established ourselves as a leading spray painting facility in the UK, specialising in high-end finishes for wooden and cladded doors. Achieving perfectly smooth, durable coatings requires a dust-free, temperature, and humidity-controlled environment, which is why all spraying is done in-house at our state-of-the-art workshop. We hand-spray every door in any RAL or designer colour, ensuring a truly bespoke finish tailored to your exact specifications. From surface preparation to drying and polishing, every stage is meticulously managed for exceptional quality.
Our spray booth utilises polyurethane paint for MDF and plywood, offering superior protection, durability, and moisture resistance. This hard-wearing finish is ideal for external doors, windows, and high-humidity environments, while also making high-gloss finishes easier to achieve.
Powder coating
We utilise precision powder coating technology to ensure superior durability, corrosion resistance, and a flawless finish for all metal components. Unlike conventional liquid coatings, powder coating provides a tougher, more resilient surface, extending the lifespan of our doors, even in extreme environments such as coastal areas and harsh weather conditions. To further enhance protection, we apply zinc primers, creating a high-performance barrier against corrosion and wear.
With access to over 500 powder options, we offer a variety of finishes, including metallic, textured, antique, matte, satin, and gloss, allowing for complete design flexibility. Our facility accommodates powder coating for components up to 3 meters in length, 2.5 meters in height, and 2 meters in width, without weight restrictions – ensuring seamless finishing for projects of any scale and complexity.
Assembly
At this critical stage of production, we apply precision and expertise to seamlessly combine wood and steel, integrating cutting-edge locking systems with bespoke handcrafted elements. At Security Doors Factory, we believe that true manufacturing excellence lies in the ability to merge traditional craftsmanship with modern technology, ensuring each door is not only a high-security solution but also a work of art.
Packing & Collection / Delivery
We take every measure to ensure our products arrive in pristine condition, carefully packed and protected for safe transit. Our final assembly team meticulously assembles and packages each order to meet customer-specific requirements, with options for custom packaging, labeling, and delivery arrangements upon request. Utilizing a combination of our own delivery fleet, national and international couriers, and a trusted network of freight carriers, we guarantee on-time delivery across the UK and worldwide, ensuring our customers receive quality products without compromise.
