Producer Membership

Get Specified. Get Qualified. Get the Work.

Architects and specifiers across the country often require Cast Stone Institute® Certified Producers in their project specifications. Without certification, your company may not even have the opportunity to bid — no matter your background or past projects.

Becoming a Certified Producer Member isn’t just about credibility.
It’s about access.
It’s about opportunity.
And it’s about being part of something bigger.

Why Become a CSI Certified Producer?

Cast Stone Institute Certified Producer Members meet the highest quality standards in the industry — and that standard is written into specifications for schools, hospitals, courthouses, commercial buildings, and more. Certification opens doors that uncertified companies simply can’t walk through.

As a CSI Certified Producer Member, you:

  • Qualify for projects that require Cast Stone Institute Certified plants

  • Gain access to more bid opportunities, especially in the public and commercial sectors

  • Build trust with specifiers through third-party verified quality and testing

  • Get listed in the CSI Certified Producer Directory, used nationwide by architects and contractors

  • Reinforce your commitment to durability, ethics, and long-term performance

  • Help shape the future of the industry through technical committees, outreach, and Institute initiatives

What Makes CSI Different?

CSI actively protects and promotes the Certified Producer specification.
Through architect education, CEU programs, and ongoing outreach to the design community, CSI ensures that the value of certification is both recognized and respected in real-world project specs.

As a member, you’re not just benefiting from that work — you’re helping lead it.

Whether you're hosting a plant tour, teaching a CEU course, contributing technical expertise, or serving on a committee, you're strengthening the entire industry — and helping ensure more architectural cast stone gets specified, used, and celebrated.

The Bottom Line

If your company isn’t certified — and the CSI spec is in the job — you may not even have a seat at the table.

For many members, CSI certification pays for itself through eligibility to bid, greater trust from specifiers, and inclusion in more high-profile projects.

But the value goes deeper.
When we set rigorous standards and hold ourselves accountable, we raise the bar — not just for one company, but for the entire industry.
The better architectural cast stone becomes, the more it's promoted. The more it's promoted, the more opportunity there is — for all of us.

That’s what CSI membership is really about:
Not just doing better work — but being better together.
