Serrmi was born out of a need to provide high-quality, customized signal solutions for the railroad industry. Brothers Larry Seward III and Dustin Seward brought Serrmi to Pittsburg, Kansas and have since built a highly qualified team of engineering and manufacturing professionals poised to produce made-to-order product solutions.



Discover Serrmi's exceptional range of products, meticulously designed to prioritize safety, quality, and functionality. Proudly manufactured in the United States, our offerings are certified to the rigorous American Association of Railroad M-1003 Standards, ensuring the highest level of performance and reliability.

Each Serrmi house and case features stainless steel three-point latching systems, guaranteeing a secure and tight closure. Our cast aluminum exterior door handles are designed to accommodate standard padlocks, ensuring enhanced security. Moreover, house doors are equipped with interior handles for convenient access when the enclosure is occupied.

We utilize premium materials to construct our houses and cases. Walls, roof, and floor panels are made from 0.100" Aluminum, Alloy 3003-H14, providing exceptional strength and resilience. Doors are crafted from 0.125" Aluminum, Alloy 3003-H14, ensuring long-lasting performance. The structural material used in each house and case is Aluminum Alloy 6061-T6, known for its superior durability.

Serrmi understands the importance of durability in all weather conditions. That's why our external hardware is either galvanized steel or stainless steel, effectively resisting weather-related corrosion. For the interior, we use stainless or zinc plated steel hardware, ensuring optimal functionality and longevity.
