All under one roof

Sierra Sheet & Plate, established in 2019, is a top tier supplier of quality titanium sheet and plate products serving the aerospace, medical, and industrial markets. The Covington, Georgia plant began life rolling molybdenum for the consumer electronics industry; in 2019 it was acquired by Tinicum and combined with Sierra Alloys and TSI Titanium to form STS Metals.

Recognized for providing a turn-key solution under one roof, SSP runs over 100,000 square feet of manufacturing anchored by a fully integrated rolling mill capable of producing industry leading titanium plate and sheet. Everything happens in-house: roll, shear, condition, water-jet, cut, heat treat, polish, pickle/chem-mill and finish. That integration, with minimal set-up time between jobs, is what lets SSP deliver custom sizes in smaller lot sizes while minimizing lead-times and cost overruns.

Inside the STS Metals network of 5 reliable companies and 7 strategic facilities, SSP is the flat products mill: more than $15,000,000 invested since the acquisition, and applications ranging from fracture critical to surgical implants. Sierra Sheet & Plate continually meets and exceeds customer expectations, specifically in the areas of Quality Material and On Time Delivery.
