ABOUT



Mason West began in 1973 as a partnership sales office representing Mason Industries’ vibration control and seismic restraint products in Southern California. By 1977, the partnership had expanded its territory to include the entire state of California and Nevada and had opened additional offices in Northern California, San Diego and Sacramento. It was 1979 when the partners officially became Mason West by incorporating in the State of California.
The company quickly outgrew their Southern California office, and in the early 1980’s the increased demand and growth lead to the acquisition of an industrial building in Anaheim with product warehousing and steel fabricating facilities. In 1985, the sales territory was again expanded to include Utah and Hawaii. Mason experienced sustained success during the late 80’s and 90’s as the need for seismic restraint systems in new development and retrofitting increased drastically. By the late 90’s Mason West became the California exclusive representative for Nexus Valve flow control products and Metal Fab venting. In 2007, the company employed more than 60 people and once again found they needed to expand their corporate headquarters. By the following year, construction on a 40,000 square foot office, warehouse, and fabrication facility in the City of Placentia was complete.
The company still maintains their satellite sales offices in Northern California, San Diego, and Sacramento and has exclusive representative in Hawaii. Our Placentia headquarters and Northern California locations have expanded even further and now offer state of the art Professional Engineering Services through AJ Engineering specializing in seismic design; vibration isolation; acoustical floors walls and ceilings; pipe thermal analysis; custom steel support design; assistance with 3D seismic brace coordination; and certified seismic layouts for all mechanical, architectural, plumbing, and electrical system needs.
