Testimonials

"The guys from Nikol-5 recently exported zinc for current project of my company Bultrade Ltd to Auckland, New Zeeland. The material was produced by NedZink in Netherlands and transported to us via Port of Rotterdam. The shippment went as planned and trouble-free. I'm very pleased to have such reliable partner in Europe on my side and I'm looking forward to doing business with them in the future."
