Material & Coating

 

Steel Grade

The quality of steel plays a major role in the performance of glass fused steel tanks. Manufacturers often use high-strength, low-alloy steel to ensure the tank can withstand internal pressure and external forces. This type of steel resists deformation and provides a solid foundation for the glass coating. When buyers select tanks with premium steel grades, they help prevent early failures and reduce the risk of leaks.

Glass Coating Quality

The glass coating acts as a protective barrier between the steel and stored contents. A high-quality glass coating bonds tightly to the steel surface during the manufacturing process. This fusion creates a non-porous layer that blocks moisture, chemicals, and contaminants. Laboratory findings indicate that the adhesion of glass to steel is significantly stronger than that of epoxy to steel, suggesting that glass fused steel tanks are less likely to experience corrosion due to coating failure.

Tip: Always ask suppliers about their glass coating process and request test results for adhesion and thickness.

Durability and Longevity

Durability and longevity set glass fused steel tanks apart from other storage solutions. The manufacturing process fuses glass and steel at high temperatures, creating a robust structure. This process delivers exceptional corrosion resistance, even in harsh environments. The table below compares corrosion resistance between glass fused steel tanks and fusion-bonded epoxy tanks:


Tank Type

Corrosion Resistance

Glass-Fused-to-Steel (GFS)

Exceptional corrosion resistance due to impermeable glass layer, protecting against moisture and chemicals.

Fusion-Bonded Epoxy (FBE)

Excellent corrosion protection but susceptible to damage from scratches, allowing corrosion if compromised.

Glass fused steel tanks withstand construction site rigors better than epoxy-coated tanks. They offer a longer service life and require less maintenance, making them a smart investment for demanding applications.
