Glass-lined steel
Glass-lined steel (also called glass-fused-to-steel) bonds a glass coating to steel sheet at high temperature. The steel provides the structure, and the glass forms a hard, impervious surface on it. The panels are usually made in a factory and bolted together on site, which suits large tanks.

Layer 01 / 03 · Faces the contents
Inner glass coat
A glass coating fused to the steel during firing. It is hard, smooth and inert, and resists sticking and staining.

Layer 02 / 03 · Carries the load
Steel substrate
Steel sheet chosen and sized for the tank’s diameter, height, contents and site loads such as wind or seismic.

Layer 03 / 03 · Faces the environment
Outer glass coat
Coating on the outside face. It protects the steel from weather and can come in a choice of colour.
- Specification
- To be confirmed
A typical glass-fused-to-steel panel section. Coating build and steel grade depend on the specification.

Properties
What it offers, and the conditions that come with it.
Each property is tied to the need it answers. Figures appear only once they're backed by a test report or datasheet.
-
Inert, hard surface
For Potable water, wastewater, process liquids
Glass does not react with many liquids and resists build-up. How well it holds up depends on the pH and temperature of the contents.
To be confirmed -
Modular bolted build
For Large volumes, remote or constrained sites
Factory-coated panels are bolted together on site, which can reduce site welding and coating work. The seams and sealant then need to be specified and inspected.
To be confirmed -
Factory-controlled coating
For Consistent finish and predictable maintenance
The coating is applied and checked in the factory before the panels leave. That avoids painting in the field, where weather and access make it harder to control.

Expandable
For Capacity that may grow
Depending on the design, bolted tanks can sometimes be extended or moved. This needs to be checked case by case.
