Welcome to the STI Global Team
Substrate Technology, Inc., plus our global partners — IMPACTS Americas, Airtec AG, Von Arx, and IBIX USA — are top leaders in the grinding and polishing industry who have developed superior products for "prep to polish" proven results. For surface prep, polished concrete, terrazzo, marble, and stone flooring, we offer superior machines and diamond system processes that work hand-in-hand with each other to go beyond what you expected.
Through two decades of product research & development at STI, as well as experience on the job, the P/M line of products was born. Every customer of ours knows that we only manufacture high quality products that meet our strict standards.
You will find grinders and diamond systems that are truly the best in the industry and will give you, as well as your clients, the floor you're looking for!
STI produces very high quality grinders / polishers that are made to last a lifetime. Prep/Master® gearboxes are made of cast aluminum and contain no belts or pulleys that break down in the middle of the night. It's a total gear-to-gear system.
Available in a range of sizes, there is always a perfect P/M machine for any project size or need. Every P/M is designed with 20 years of research and development to give you the very best the industry can offer. P/M machines can do everything from prep to polish!
