What Our Customers Have to Say...

“I have been in the industry now for 30 years. I’ve found that 21 Micro milling blows away Blanchard Grinding. We receive a more accurate plate for less money and in less time.”


General Manager

“I have worked with Kimm for over 30 years and his new process, the ‘21 Micro Mill,’ is a game-changer. We send all of our jobs to Steel 21.”


General Manager

“Our company has been striving to be more environmentally friendly, so it was cool to find out that 21 Micro Milling is 100% recyclable. I never knew that the Blanchard Ground plate we used  to order contributed to metal sludge waste… It was great to learn that we aren’t only receiving a better quality plate from Steel 21, the process is also better for our planet.”
