The Loire department is home to a diverse array of manufacturing companies, ranging from large international groups to established mid-sized firms. These companies specialize in sectors such as chemical manufacturing, industrial machinery, medical equipment, and food production. Many have a long history, with several founded in the mid-20th century or earlier.
Notable companies include SNF, a major producer of water-soluble polymers; Desjoyaux pools, a global leader in buried pool construction; HEF Groupe, specializing in surface materials engineering; and SIGVARIS GROUP France, a family-owned leader in medical compression.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
