Seamless Pipes
Seamless Pipes are manufactured from solid steel billets without any welding seams, ensuring superior strength and reliability. They are the preferred choice for critical applications requiring high pressure and temperature resistance in demanding industrial environments.
Welded Pipes (ERW/EFW)
Welded Pipes are produced by forming steel plates or strips and welding the seam longitudinally or spirally. Known for their consistent wall thickness and dimensional accuracy, they offer a cost-effective solution for large-scale infrastructure, water transport, and structural applications.
"At Unicorn Metal Industries, we don't just supply pipes; we deliver the backbone of industrial infrastructure. Our commitment to high-grade materials ensures every project stands the test of time."
