Our Story

From a Small Workshop to a Trusted Manufacturer

2007

Founded in Lin'an, Hangzhou

Hangzhou Linan Zhonghe Metal Products Co., Ltd. was established with a single press brake and a handful of skilled metalworkers. The mission was simple: deliver quality sheet metal fabrication with integrity.

2010

Expanded into Enclosure Manufacturing

Recognizing growing demand for custom electrical and network enclosures, we invested in our first CNC turret punch and expanded our bending capacity. This marked our shift from general fabrication to enclosure specialization.

2015

Built In-House Powder Coating Line

To control quality and lead time, we brought surface finishing in-house. Our own spray booth and curing oven meant faster turnaround and consistent RAL color matching — no more relying on third-party coaters.

2020

Laser Cutting & 30+ Team

Added a Hongshan fiber laser cutting machine for precision blanking. Our team grew to 30+ skilled craftsmen — welders, press brake operators, finishers, and QC inspectors — all working under one roof.

2026

Going Global — ZentFab

With nearly two decades of experience and thousands of custom enclosures delivered, we launched the ZentFab brand to serve international clients. Same craftsmanship, same commitment — now available worldwide.
