About Us


Seneca Dairy Systems LLC is a versatile company originally known as Green Valley Welding established in 1978. Green Valley Welding was a small business that began manufacturing freestalls and other farm and dairy equipment for local farmers. In 1999, Seneca Iron Works purchased the company and began heavily investing in technology with a strong focus on R&D. We quickly expanded our product line and were able to grow our customer base nationwide. With customer service and high quality products with innovative design the top priorities, we have become one of the most trusted companies in the business.

If you're not already a customer, shame on you 😉 Just give us a call, we'd love to be your next dairy solutions provider!
