Our Factory
SIAN PROTECH — built in 2015, the manufacturing backbone behind EASTRAGON
Eastragon Trade was founded in 2005. To control quality at the source, we built our own factory SIAN PROTECH in 2015, integrating extrusion, molding, acoustic testing and packaging under one roof. This dual structure — trade brand + own factory — is why distributors in 50+ countries trust EASTRAGON for both core SKUs and curated portfolio sourcing.
