S355JO Angle is also an important material in bridge construction. Due to its high strength and corrosion resistance, S355JO Angle can withstand the heavy loads and severe environmental conditions of bridges. In bridge structures, S355JO Angle is often used for components such as girders, bull legs and cross beams.

S355JO Angle is widely used in the manufacture of machine tool components. Due to its high strength and excellent wear resistance, S355JO Angle is able to maintain good stability under high intensity working condition. In machine tool manufacturing, S355JO Angle is often used for components such as racks, columns and sliding beds.
