Online Diamond Plate, established in 2013, had its humble beginnings in a modest suburban garage in Golden, Colorado. What started as a side venture rapidly expanded beyond its initial confines, flourishing into a reputable business.

Despite our significant growth, we remain a family-owned enterprise, deeply rooted in Golden, Colorado, and committed to the core values that have shaped our journey. Our personalized, family-style service ensures that each customer receives the attention and care they deserve.

Our primary focus lies in providing high-quality aluminum diamond plate sheets and related accessories, which are frequently utilized in interior walls and trailers. Our diverse clientele includes fitness centers, large retailers, restaurants, trailer manufacturers, camper repair services, and military organizations, among others.

At Online Diamond Plate, we take pride in catering to the varied needs of our customers with excellence, integrity, and the warmth of our family-oriented approach.
