Hot-Rolled Pickled & Oiled | HR350

Hot-Rolled Pickled & Oiled | HR350 Specifications

Produced from New Zealand made, hot-rolled, pickled, and oiled steel coil.

HR350 provides a clean, consistent semi-bright finish thanks to pickling, oiling, and skin-passing, with OD accuracy comparable to CR250.
The higher yield strength delivers improved performance in brackets, supports, frames, and other applications exposed to greater physical loads.
Excellent dimensional stability and weldability make it suitable for a wide range of medium-duty fabrications.
