Overview of GFS Tank Solutions

VIET WATER JSC is proud to provide Glass-Fused-to-Steel (GFS) tank solutions that meet international standards for large-scale clean water and wastewater treatment systems.

With outstanding advantages in corrosion resistance, long service life, fast installation, and low operating costs, GFS tanks have become a preferred solution for many industrial and environmental projects worldwide.

The GFS tank systems supplied by Viet Water have been successfully implemented in several major projects in Vietnam, contributing to sustainable operation and long-term investment efficiency.

What Is a GFS Tank?

A Glass-Fused-to-Steel (GFS) tank combines high-strength steel with a glass coating fused at temperatures between 820°C and 930°C. This process creates a highly durable and corrosion-resistant surface capable of withstanding harsh operating environments.

The tanks are assembled using bolted panels, allowing rapid installation and easy future expansion.

Compliance with International Safety Standards

The GFS tank system is designed and manufactured according to strict international standards.

Designed in Accordance with AWWA D103-09

All bolted steel tanks are designed following the AWWA D103-09 standard.

OSHA-Compliant Safety Accessories

The system includes:

• Safety ladders

• Working platforms

• Handrails

• Anti-climbing devices

• Lightning protection systems

Safe and Reliable Operation

These features ensure stable and safe operation throughout the entire service life of the tank.

👉 Providing maximum operational safety.
