The Belden Brick Company, a long-standing pillar in the brick industry, is the largest family-owned brick manufacturer in the United States. Expanding brick's creative versatility while maintaining the material's traditional strengths is something in which we pride ourselves. We continue to meet the changing needs of the construction market by manufacturing over 20 different face brick and clay paver sizes, more than 500 colors, 13 different textures, and endless designs of special shapes. The superior quality of our raw materials leads to the structural integrity and outstanding appearance of our line of world-class architectural brick. Each brick becomes part of a legacy that has set The Standard of Comparison since 1885.
