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.
