Application

JIS G 3114 steel plate application:
The anticorrosive properties of weather resistant steel are better than those of other structural steels in many applications. The JIS G3114 steel plate is self-protecting: The rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion. The steel is an economical, long-lasting and fully recyclable material.
