KS & JIS Specifications
Two types of zinc coating weights?the same weight on both sides and differentiated weights on each side?are applied to the steel sheets and steel coils. The standard and minimum Zn coating weights are marked with a code combining the coating weight of each side. The marking methods are as follows.
When attaching a label indicating an application of “differentiated coating weights” on two sides of the steel sheets or coils, a letter “D” is written after the minimum coating weight code on the surface with the label. (e.g., E8/E16D)

El Galvanizado en caliente es un proceso que consiste en la aplicación de recubrimiento superficial de zinc sobre elemento de hierro y acero mediante la inmersión de zinc fundido a una temperatura de 450°C.. El objetivo de este proceso es conseguir la protección de las piezas o elementos metálicos frente a la corrosión por humedad y/o contaminación ambiental.
El Galvanneal es un proceso donde el acero se sumerge en un baño caliente de zinc (similar al proceso de Galvanizado), luego es sometido a un proceso secundario en el que el hierro se recuece con el revestimiento de zinc para crear una mezcla de hierro - zinc en la superficie del metal. El Galvanneal proporciona mayores beneficios en procesos tales como soldabilidad, pintura, formalidad y resistencia a la corrosión
Los productos de acero inoxidable se pueden clasificar en acero inoxidable austenítico, acero inoxidable ferrítico y acero inoxidable martensítico según sus componentes de aleación y estructura de tejido. Sus aplicaciones típicas incluyen tubos de escape de automóviles, electrodomésticos de cocina, electrónica y materiales de construcción. Las aplicaciones emergentes incluyen sectores ecológicos, como cajas de baterías EV y GNL.
