SDF (Single Door Frame)

Made through controlled, product-relevant stages.

SDF (Single Door Frame) is a strong and durable steel section specially designed for door frame applications. Manufactured from high-quality steel with precise dimensions and a smooth finish, it offers excellent strength, stability, and long-lasting performance. SDF sections are easy to install, resistant to wear and deformation, and provide a reliable framework for doors in residential, commercial, and industrial buildings. Their robust construction ensures better support and enhanced durability compared to traditional wooden frames.

   Slitting

   The levelled steel coils are processed through high-precision slitting machines where they are cut longitudinally into specific widths according to the required pipe and tube dimensions. The slitting process is carried out with strict dimensional tolerances to ensure uniform strip width and edge quality. Accurate slitting contributes significantly to proper tube formation, welding consistency, and overall product quality in subsequent manufacturing stages.

   Tube Mill

   In the tube mill section, slit steel strips are gradually formed into round, square, or rectangular tubular shapes using advanced forming rolls and automated machinery. The open edges of the formed sections are welded continuously using the Electric Resistance Welding (ERW) process, which produces strong, uniform, and reliable weld joints. The tube mill operation is carefully controlled to maintain dimensional accuracy, structural integrity, smooth weld finish, and superior mechanical performance of the finished pipes and tubes.

   Finishing & Packaging

   The finished pipes and tubes are carefully bundled, packed, labeled, and secured using suitable packaging methods to prevent physical damage, moisture exposure, and handling defects during storage and transportation. Proper packaging ensures safe delivery, efficient inventory management, and product protection throughout the supply chain until final dispatch to customers.
