Our History — 27 Years of Precision & Trust

1998 · Hong Kong Roots
Great System Industry (GSI) was founded in Hong Kong with a clear mission: to bridge the gap between world-class instrumentation manufacturers and end-users in Asia's fast-growing industrial sector. The company began as a specialized distributor of process control instruments, focusing on pressure and temperature measurement solutions.

2003 – 2008 · Building the Portfolio
Over its first decade, GSI systematically expanded its product lines and brand partnerships. Key milestones included becoming an authorized distributor for Emerson Rosemount

pressure transmitters and Yokogawa EJA series — two of the industry's most trusted measurement platforms. This period also saw the company adding flow, level, and analytical instrumentation to its catalog.

2009 – 2014 · Scaling Globally
With a proven supply chain and deep technical expertise, GSI shifted its focus toward international markets. Export share climbed rapidly, reaching 60%+ of total revenue. The company established logistics partnerships across Europe, Southeast Asia, and the Middle East, laying the groundwork for its global footprint.

2015 – 2020 · Brand Matrix Expansion
GSI entered a high-growth phase, expanding its authorized brand portfolio to 15+ world-class manufacturers including Siemens, ABB, VEGA, GE Bently Nevada, Allen-Bradley, Micro Motion, Teledyne, and Endress+Hauser.

The product range now covers the complete spectrum of industrial automation — from PLC modules and safety barriers to valve positioners and gas analyzers.

2021 – Present · 6000+ Customers, One Promise
Today, GSI serves over 6,000 customers worldwide with an annual turnover of $7–10 million and an export ratio of 80%–90%. Headquartered in Shenzhen with its original Hong Kong office, the company maintains a 30-member professional team dedicated to technical consultation, quality assurance, and global fulfillment. Our promise remains unchanged: genuine products, responsive service, and engineering-grade precision — every order, every time.

Our Team — Engineering-Driven, Customer-Focused
