About Lamasi Iron Works

IMG_3593.HEIC

Lamasi Iron Works is a family-owned and operated company, founded in 1984 by two brothers from Jerez, Zacatecas Mexico; Luis and Ruben Diaz.

In 1990 Luis left Lamasi Iron Works and started Cinco Iron Works in Ontario CA. 

With over 50 years of knowledge, Ruben began fabricating and building at the young age of 15. We've worked with several leading companies such as In-n-Out, California Pools, Mur-sol Builders, and more.

 

Now with the help of his son Ruben and Grandson Nathaniel, the tradition and experience continue. 

Our mission is to deliver the highest quality fabrication, design, and installation services, all while providing exceptional customer service.
