Static protection is based on engineering. We create physical static protection barriers through standardized processes, precise implementation and strict acceptance.

Static Grounding Excavation & Installation

Professional systematic static grounding construction to solve industrial static safety problems from the source

Static Grounding Excavation and Installation

Industrial static grounding is a basic project for factory safety. We focus on grounding grid excavation, electrode embedding, cable laying, system construction and EPA anti-static engineering, providing standardized solutions for industrial enterprises.

Standardized grounding construction can quickly discharge static electricity, avoid risks such as spark discharge and dust adsorption, eliminate fire, explosion and equipment failures, and improve factory safety and production stability.
