“I have worked with Metal Supply on a number of projects. One in particular, when we did the initial start-up of CT-2 (combustion turbine), the turbine for lack of a better term “puffed” and sent a great deal of pressure up against our diffuser plate, catalyst bed and lifted plating on the duct flooring. After inspecting the damag,e the list of materials was quite substantial and of course all of this took place on a saturday. I contacted metal supply and supplied them with a list of materials as well as certain designs that needed to be fabricated. They had their manager meet me at the shop, they had all of the materials we needed, everything we asked for he was able to fabricate for us(sheet metal, flatbar bent and or cut to certain specs). I also placed a call the next day being Sunday and was met with the same professional attitude and I was very pleased with the service and products. thank you metal supply for all the assistance!”

~Daniel Waters


“This letter is inform you that Metal Supply has been working on a major project at the Chevron refinery in El Segundo. The level of commitment, professionalism and communication set forth by Metal Supply aided in the overall success of this project.

All delivery dates have been met, actually some have been improved. All shop drawings have been on time or early, and most importantly the level of communication brought forth by the Metal Supply project management team has been exceptional.

I will highly recommend Metal Supply for any job. and look forward to working with this company in the future.”

~Fred Mohtashemi, Project Manager

Brinderson logo

“First, I would like to thank Ray Castro and his fabrication team for coordinating the fabrication of Expansion Joint for the Air Preheater Replacement project.
The team has done a GREAT JOB!
Normal fabrication would have taken 2 to 3 weeks to get it out of the shop, but in this case, the complete order was fabricated and delivered in matter of 48 hours.
Definitely your company has surprised a few folks here at Phillips 66 of your capability supporting difficulty.”

~Lee Spalding Sr. F.E., Brinderson Constructors

Mustang Engineer

“Mustang Engineers and Constructors, L.P. served as the engineering, procurement and construction management contractor for the Flare Gas Recovery projects at Chevron’s El Segundo Refinery. I wanted to take this opportunity to thank Metal Supply, Inc. for the outstanding work you did for us on these projects. As a result of your efforts one of these projects was awarded the Western Council of Construction Consumers (WCCC) Distinguished Project Award for 2009.

MSI fabricated over 800 tons of steel for these projects with near zero fabricator errors. Our construction management team told me on several occasions this was the best steel design and fabrication effort they had ever worked on. Coming from a team that has an average of over 30 years experience in the business, this is the ultimate compliment in my mind. All this was accomplished with some very aggressive schedule requirements; you were able to meet all our delivery needs.

Mustang looks forward to working with you again in the near future.”

~Tommy T. Bennett, Project Manager


“We worked directly with you on the last minute, hot rush fabrication orders. MSI’s communication and support throughout the project exceeded our expectations. Specifically, your availability all hours of the day, and the sense of urgency on our orders was appreciated. Metal Supply met all promises on deliveries, professionalism was unrivaled and quality was never an issue.”

Steel Welding | AWS D1.1 Certification

The American Welding Society, AWS, has been the leading nonprofit organization focusing to advance the science, technology, and application of steel welding and cutting processes.

Issuing eight industry recognized program certification categories, including welding inspector (CWI) and fabricator (CW) program to name a few. A welder who successfully qualifies to AWS certification has been tested on procedures used in the structural steel, petroleum pipelines, sheet metal, and chemical refinery welding industries. Successful companies have come to rely on a certified welding inspector (CWI) to ensure the highest level of quality workmanship.

Steel welding is a valuable commodity used in industrial to residential projects, so the value of welding in today’s world is essential. Various types of metal require specialized care, so the AWS D1.1 certification is vital.
