At Building Products Group in St. Louis, MO, we take pride in delivering premium cast bronze and aluminum architectural signage that blends beauty, precision, and permanence. Every plaque, letter, and sign we produce is designed to communicate excellence — whether identifying a business, commemorating an achievement, or enhancing a building’s architectural presence. Our team provides custom design assistance and fabrication for projects of any size or scope, ensuring every detail meets the highest standards of craftsmanship.

Each project begins with a personalized consultation to understand your goals, style preferences, and installation environment. Our skilled designers then develop detailed layouts that reflect your vision, incorporating typography, logos, and finishes that align seamlessly with your brand or architectural theme.

Every cast bronze or aluminum plaque and letter is tailor-made — no two pieces are ever the same. From initial concept through to casting, finishing, and installation, we manage the entire process to ensure the end product delivers a bold, professional, and lasting impression.

The Timeless Appeal of Cast Bronze

Cast bronze signage has been a symbol of durability and prestige for generations. Known for its rich color, classic texture, and resistance to corrosion, bronze is an ideal material for both indoor and outdoor installations. Whether it’s a historical marker, corporate logo, or commemorative plaque, our bronze castings offer an unmatched depth of character and permanence.

We provide a wide selection of finishes, including brushed, polished, and patina effects that age gracefully over time. Our plaques can be enhanced with raised or recessed text, portraits, or graphic artwork, giving each piece a distinctive and refined look.

Sleek and Modern Aluminum Signage

For contemporary architectural projects, cast aluminum signage delivers a sleek, modern aesthetic with outstanding performance. Lightweight yet strong, aluminum is ideal for architectural letters, directional signs, and identification plaques. Its versatility allows for a wide range of finishes — from natural satin and painted coatings to anodized or powder-coated surfaces. Aluminum signs and letters are also a cost-effective option for large-scale projects, offering a balance of affordability and design flexibility without compromising quality or longevity.

Architectural Letters with Impact

Our dimensional letters — available in both bronze and aluminum — are custom-cast to elevate the visual presence of any building façade, monument, or entryway. They add depth, sophistication, and visibility, making them an excellent choice for universities, government buildings, corporate headquarters, and religious institutions.

With multiple mounting options and letter styles available, we can adapt your design for flat wall surfaces, stand-off installations, or embedded settings. Each letter is engineered for precision, balance, and long-term stability, ensuring it retains its shape and finish for decades.

Tailored for Every Setting

From memorial plaques and wayfinding systems to dedication walls and business signage, our cast metal products are suited for a broad range of environments. They withstand the elements, maintain their finish, and uphold their structural integrity even in demanding outdoor conditions.

Because all our work is custom fabricated, you have full control over dimensions, layout, font, color, and mounting methods. Whether you need a single engraved dedication plate or a complete architectural signage program, Building Products Group provides solutions that are elegant, durable, and fully tailored to your project.

Quality That Lasts a Lifetime

Our casting process ensures exceptional density, uniformity, and fine detail. Each plaque or letter is meticulously inspected before leaving our facility, guaranteeing a flawless finish that reflects the professionalism and pride of your organization. These signs are built to endure — resisting fading, corrosion, and wear while maintaining their striking appearance over time.

At Building Products Group, our passion for craftsmanship is matched only by our commitment to customer satisfaction. We combine traditional casting techniques with modern technology to produce architectural signage and plaques that honor history, celebrate achievement, and inspire recognition.
