We are proud to announce that after passing another rigorous inspection, we have maintained our RTP-1 re-certification from ASME (American Society of Mechanical Engineers).

One of only a few FRP fabricators to attain this certification, Diamond utilizes rigorous shop procedures, documentation requirements and quality assurance procedures to qualify.

RTP-1 certification is an independent acknowledgement that our new facility meets the most stringent composite vessel standards in the industry.

ASME RTP-1 certification is an excellent way for customers to separate the industry leaders from the followers.  Some competitors claim their shop is capable and equipment meets RTP-1 standards, but that isn’t the same as demonstrating the ability through an extensive company-wide third party audit.

We first received certification in 2009 and while audited annually under the program, we must also re-certify regularly.  Our new physical plant was purpose-designed and built for FRP fabrication, and our engineering, fabrication, quality assurance and personnel qualification procedures remained the same as previously approved so the latest audit went smoothly.

Congratulations to the engineers, production staff and quality assurance teams at Diamond Fiberglass for achieving this accomplishment!
