DESCRIPTION
CRGO Steel materials come in two forms: Coils and sheets. A full width coils can weight up to 6 metric tons each. This unique steel is available in various thicknesses ranging from 0.18MM – 0.35 MM and more commonly has come to be referred to globally by grades M2-M6.
CRGO steel is used in manufacturing the magnetic core for power and distribution transformers. Working with this unique and specialized steel, we are able to provide our customer full-width CRGO coils & slit coils for their transformer production needs. Cold-rolled grain-oriented steel is often abbreviated to CRGO. The growing demands of our customers are met by continually offering an assortment of materials with various core losses w/kg.
