Laboratory
At POLYSTEEL, quality is not just a buzzword; it’s a precise system of checks that operates every day. We adhere to European standards EN10169 and EN10346, so every coil undergoes thorough inspection before reaching the client. Each coil comes with a quality certificate, and upon request, a coil passport with full technical specifications and test results. Quality control is not just a production stage—it is proof that every POLYSTEEL coil is consistent, verified, and reliable.
