corrosion resistant

Corrosion resistant galvanized steel

Laser cut G30 can withstand even the most aggressive of environments thanks to its hot-dipped zinc coating. With corrosion resistance and stain resistance, G30 is also highly conductive and well-suited for electronic applications: developed with the input of computer company engineers, G30 was created to fulfill the necessary requirements for applications in the computer cabinet and electronic chassis market. And with minimum spangle, you won’t find a more aesthetically pleasing material for your computer and electronic projects.

Superior formability and corrosion resistance

One of the biggest benefits to laser cut G30 is its workability. Well-suited for post-processing, G30 has superior manufacturability, and is easily finished with further protectants.  

Here at SendCutSend, we pride ourselves on our high quality bending and powder coating services, which can both be used in conjunction with G30 to improve even further on its best qualities.
