¿Qué es el galvanizado en caliente y para qué sirve?

El galvanizado en caliente es un proceso que recubre el acero con zinc fundido, creando una barrera anticorrosiva que protege contra la oxidación y el desgaste. Es ideal para estructuras metálicas expuestas a la intemperie o ambientes agresivos.

¿Cuánto dura el galvanizado en caliente?

Dependiendo del ambiente, el acero galvanizado puede durar entre 20 y 40 años sin necesidad de mantenimiento. En entornos industriales o marinos, su resistencia sigue siendo superior a la de otros recubrimientos.

¿Por qué elegir acero galvanizado para estructuras metálicas?

✔ Protección total contra la corrosión. ✔ Mayor vida útil sin mantenimiento. ✔ Resistencia a golpes y arañazos. ✔ Ahorro a largo plazo en costos de reparación y pintura.

¿Se puede pintar sobre acero galvanizado?

Sí, con el Sistema Dúplex, que combina galvanizado en caliente con pintura especializada. Esto mejora la protección anticorrosiva y permite elegir el color y acabado deseado.

¿Cuáles son las aplicaciones del galvanizado en caliente?

El acero galvanizado se usa en: ✅ Estructuras metálicas para construcción (cerchas, cubiertas, vigas). ✅ Perfiles galvanizados para construcción en seco. ✅ Infraestructuras industriales y naves metálicas. ✅ Proyectos expuestos a humedad o condiciones extremas.

¿El galvanizado en caliente afecta la resistencia del acero?

No. El proceso de galvanizado en caliente no altera la resistencia mecánica del acero. De hecho, añade una capa extra de protección sin comprometer su solidez estructural.

¿Cuál es el precio del galvanizado en caliente?

El precio del galvanizado en caliente depende del tamaño y tipo de estructura. Solicita una cotización para conocer el costo exacto según tu proyecto.

FAQ’s

What is hot-dip galvanizing and what is it used for?

Hot-dip galvanizing is a process that coats steel with molten zinc, creating an anti-corrosion barrier that protects against rust and wear. It is ideal for steel structures exposed to the elements or aggressive environments.

How long does hot-dip galvanizing last?

Depending on the environment, galvanized steel can last between 20 and 40 years with no maintenance required. In industrial or marine environments, its resistance remains superior to that of other coatings.

Why choose galvanized steel for metal structures?

✔ Complete protection against corrosion.
✔ Longer service life with no maintenance.
✔ Resistance to impacts and scratches.
✔ Long-term savings on repair and painting costs.

Can galvanized steel be painted over?

Yes, with the Duplex System, which combines hot-dip galvanizing with specialized paint. This enhances the anti-corrosion protection and allows you to choose the desired color and finish.

What are the applications of hot-dip galvanizing?

Galvanized steel is used in:
✅ Steel structures for construction (trusses, roofing, beams).
✅Galvanized profiles for drywall construction.
✅ Industrial infrastructure and steel buildings.
✅ Projects exposed to humidity or extreme conditions.

Does hot-dip galvanizing affect the strength of steel?

No. The hot-dip galvanizing process does not alter the mechanical strength of the steel. In fact, it adds an extra layer of protection without compromising its structural integrity.

What is the price of hot-dip galvanizing?

The price of hot-dip galvanizing depends on the size and type of the structure. Request a quote to find out the exact cost for your project.
