Every product we carry is spec'd for Gulf Coast energy and infrastructure — petrochemical, offshore, marine, and heavy industrial applications.

Family-Owned Commitment

Since 1938 we've operated on one principle: a handshake has meaning and our word is our bond. You deal with people who stand behind what they say.

Custom Fabrication

Our 1-acre fabrication facility handles custom cuts, sizing, and assemblies. Tailored to your exact project specs, built for the job you're actually running.

A Legacy Built on
Keeping Your Word

In 1938, Gaiennie Lumber opened its doors in Opelousas, Louisiana as a wholesale lumber supplier. Our industrial division was born when a local client needed highly specialized materials for an industrial cooling tower — a complex job other companies refused to take on.

A dedicated Gaiennie employee stepped forward, shook the client's hand, and gave his word to get it done. That relentless commitment left a lasting impression, and word spread quickly.

Over eight decades later, Gaiennie Industrial continues to serve heavy contractors, builders, and engineers across the Gulf Coast corridor.

"We still believe that a handshake has meaning,
and that our word is our bond."
