Welcome to the STI Global Team!
Substrate Technology, Inc., plus our global partners — IMPACTS Americas, Airtec AG, and IBIX USA — are top leaders in the grinding, polishing, and blasting industry who have developed superior products for "prep to polish" with proven results. For surface prep, polished concrete, terrazzo, marble, and stone, we offer superior machines and diamond system processes that work hand-in-hand with each other to go beyond what you expect.
Through two decades of product research & development at STI, as well as experience on the job, the Prep/Master® 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 blasting equipment, grinders, and diamond systems that are truly the best in the industry and will give you, as well as your customers, the results 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!
