Quality is non-negotiable

GrayWolf Industrial’s commitment to quality stems from a deep commitment to integrity. We don’t believe in doing work unless it’s done right. And that’s a top-down and bottom-up philosophy. Our strength lies in the productivity of management and the advanced skills of the craftsmen. GrayWolf employees at every level take the responsibility of delivering quality work personally.

Above the standard

Meeting even the most stringent industry standards is not enough. Our quality control department employs extensive testing and inspection methods to ensure that each project is completed in accordance with all client, industry and code standards and requirements. At GrayWolf, we’ve designed our quality assurance measures and quality control procedures to exceed generally accepted quality practices of the construction industry.

Staying sharp through training

To keep our quality from ever diminishing, GrayWolf invests in craft employee’s knowledge and skill level through rigorous and regular training and professional development. We have an exceptional craft training center, where both new and experienced craftsmen come to learn how to be the best.
