GalvStone was founded on a simple belief — that the most beautiful designs are also the most durable. As a division of KAM Interior Supply, GalvStone combines porcelain stone, authentic marble, and galvanized steel to craft furniture and surfaces built for a lifetime of performance.
Every collection is defined by a mix of innovation, material quality, and timeless design — created to enhance kitchens, patios, and hospitality spaces alike.
We don’t only build surfaces. We craft statements that endure.
GalvStone was founded on a passion for craftsmanship and a commitment to using durable materials. What began as an effort to combine industrial strength with elegant design has grown into a complete collection of premium porcelain and marble furnishings.
As part of KAM Interior Supply, we maintain a tradition of quality, precision, and partnership — collaborating with designers, architects, and homeowners who appreciate both artistry and performance.
From small residential projects to commercial installations, our mission stays the same: to craft pieces that inspire confidence, connection, and lasting beauty.
