Who We Are

Since the company was started in 2003, S & D Materials has operated on the principle that every point of contact between trading partners is an opportunity to either add value to the relationship, or take it away. We work to add to that value every time. We’re reliable, responsive, thorough and honest, and we will never take for granted when a customer trusts us with their business. We honor our commitments, we communicate quickly, we deliver solutions despite the challenges, and our lean operation lets us offer the best pricing possible.
