Quality Materials — We use thick, high-quality American-milled steel plate for our central mix blades. We encourage you to compare our material thickness and properties with our competition.  We believe in the tried and proven concept that Heavier steel = less flexing = less cracking = longer-lasting drum.

Desire to Be the Best — Built by guys who truly want to exceed your expectations. As a small to mid-sized company, we understand the connection between customer satisfaction and our job security.

Experience — When you consider the average length of employment is over 16 years for our production personnel, it is easy to feel assured that you are dealing with skilled workers that are definitely masters of their trade.

    While we offer several great options for central mix blade liners, the actual drum liners themselves are almost always going to be urethane. No other material matches the wear properties at a comparable cost. So, if you need urethane drum liners why chose Durex? Because it lasts longer than any other urethane in the market. Check out this brochure (PDF) for more details.

Currently, we are seeing a proven material replace wrap around urethane.
