Manufacturing Process

Manufacturing Process

The quality of a steel door depends not only on the materials used but also on the precision applied throughout every stage of production. At ASIR Steel Door, we combine modern manufacturing technologies with our experienced team and quality-oriented production philosophy to manufacture every product to the same high standards. Every step of our production process is carefully inspected to ensure durability, security, and aesthetics in every door.

Laser Cutting

Our manufacturing process begins with high-precision CNC laser cutting technology. Steel sheets are cut with millimeter accuracy using computer-controlled machines, preparing every component perfectly for the following production stages. This technology minimizes production errors while maintaining consistent quality standards.

Bending Process

After cutting, all components are shaped to the required dimensions and angles using CNC press brake machines. The controlled bending process strengthens the structural integrity of the door while ensuring maximum assembly accuracy and outstanding mechanical durability.

Welding Process

After the bending stage, all components are assembled by our experienced welding specialists. Every welding point is carefully applied and inspected through strict quality control procedures. This process creates a strong and reliable door structure that maintains its form for many years.

Electrostatic Powder Coating

Once welding is completed and the surface preparation process is finished, electrostatic powder coating is applied. This coating method distributes the paint evenly across the surface, providing excellent resistance against impacts, scratches, moisture, and various environmental conditions.

Paint Curing

Doors coated with electrostatic powder paint are cured in temperature-controlled industrial ovens. The curing process ensures maximum paint adhesion, resulting in a durable, long-lasting, and aesthetically refined surface finish.

Insulation and Filling

Special filling materials are applied inside the door leaf to improve both thermal and acoustic insulation while increasing impact resistance. This process enhances everyday comfort and helps the door maintain its original performance for many years.

Mechanical Assembly

Locking systems, hinges, handles, and all accessories are carefully assembled by our experienced technical team. After assembly, every product undergoes comprehensive functional testing to verify its mechanical performance before leaving the production line.

Packaging and Shipping

Products that successfully pass all quality control inspections are packaged using specially designed protective materials to prevent damage during transportation. Safe logistics solutions are used for both domestic and international deliveries, ensuring every product reaches our customers in perfect condition.
