About Us
SIJINUS Metal Constructions started as a small welding workshop with a simple standard: every weld, every gate and every structure had to be built to last. That standard hasn't changed as we've grown.
Today we serve homeowners, businesses, contractors, marine operators and industrial clients across Port Harcourt and Rivers State — handling everything from a single security gate to full structural fabrication for industrial sites.
What hasn't changed is the craftsmanship. Our welders are trained, our materials are sourced for strength, and our team shows up when we say we will.
