The sheet metal workshop is the starting point of steel door production. Raw steel coils and sheets are first prepared for further processing.
Steel coils are uncoiled and leveled through a dedicated production line to create a flat and consistent material surface. The prepared steel is then processed according to the required door specifications.
Laser cutting is used to accurately cut steel sheets and structural components. Precise cutting helps ensure consistent dimensions and provides a reliable foundation for subsequent forming and assembly.
After cutting, steel components can go through stamping, bending and forming processes. Door leaves, frames and reinforcement components are produced according to the door design.
The door frame components are then assembled and welded. Careful welding and dimensional control help create a stable structure for the finished steel security door.
After the metal components are processed, the door moves into the gluing workshop.
Depending on the product design, decorative panels and surface materials are prepared and bonded to the door structure. Adhesive is applied to the required areas before the panels are accurately positioned.
The bonding process is carefully controlled to maintain proper alignment, surface flatness and a strong connection between the materials. Pressure bonding helps improve the stability of the finished surface.
This stage allows PHIPULO to combine the structural advantages of steel with different decorative designs, making steel doors suitable for a wide range of residential and architectural applications.
Surface treatment is an important part of steel door manufacturing because it determines much of the door's final appearance and surface performance.
Before coating, the door components are prepared and cleaned to provide a suitable surface for treatment.
The prepared components are transferred through the powder-coating production line. Powder coating can provide different colors and surface effects while creating a durable finish.
Depending on the design, doors can also feature different decorative textures and finishes to match residential entrances, villas and other architectural styles.
After coating, the finished surfaces are inspected for coating consistency, color, texture and visible defects.
A properly controlled surface treatment process not only improves appearance but also helps protect the steel surface during everyday use.
Once surface treatment is completed, the door components enter the assembly workshop.
This is where the door leaf, frame, hardware and accessories are combined into a complete product.
PHIPULO also specializes in smart fingerprint locks, providing options for customers looking for modern access solutions.
The door leaf is assembled with the corresponding frame and hardware. Workers check the alignment of the door components and make necessary adjustments.
The finished door is then tested for opening and closing performance, lock operation and hardware installation.
Proper assembly ensures that the individual components work together as a complete door system rather than simply functioning as separate parts.
Quality control runs throughout the manufacturing process. Before shipment, finished doors undergo final inspection covering dimensions, appearance, hardware installation, locking function and overall assembly.
For customized orders, the production team can check the finished product against confirmed specifications, including door size, surface finish, hardware configuration and other requirements.
After inspection, the doors are carefully packaged to reduce the risk of scratches or damage during transportation. Finished products can then be loaded onto trucks or into containers for delivery.
Although the Steel door is an important part of PHIPULO's product range, the company also offers other door solutions for different applications.
A Cast Aluminum door can provide a distinctive architectural appearance with cast metal decorative elements, while a Wooden door offers a natural and traditional visual style. Steel security doors, meanwhile, are widely selected when strength, security and durability are important considerations.
By offering different door categories, PHIPULO can support distributors, importers, contractors and project buyers with products suited to different markets and building requirements.
For international buyers, choosing a door supplier is about more than comparing product photos and prices. The manufacturing process provides important information about a company's production capabilities and quality control.
A complete production flow includes:
Raw Steel → Sheet Metal Processing → Gluing → Surface Treatment → Assembly → Quality Inspection → Packaging → Delivery
Each stage contributes to the final product. Accurate metal processing supports structural consistency, proper bonding improves surface stability, professional coating creates the desired finish, and careful assembly ensures reliable daily operation.
From raw steel to a finished security entrance door, every production stage plays a role in the final quality of the product.
With manufacturing experience dating back to 2003, PHIPULO focuses on steel security doors and a range of other door solutions for residential, villa and building projects. Through specialized production processes and quality control, PHIPULO aims to provide reliable door products for customers and partners in international markets.
