English to Croatian Other Construction / Civil Engineering

Hi! I'm translating a presentation on different types of products that the parent company of a roofing company offers. The presentation is aimed at possible Croatian distributors. I am stuck on the phrase "long steel". Here is the context:

Furthermore, Cement, Readymix, Aggregates, Concrete products, Concrete pipes, Quarries, Long steel, Reinforcing bar, mesh and wire, Iplex pipeline, Copper tube.

I would appreciate any help. Thank you!
