Glass-Fused-to-Steel Technology is a leading solution combines the advantages of both materials — the strength and flexibility of the STEEL and highest corrosion resistance of the GLASS. The Glass fused to the Steel at  1500 — 1650 deg. F (800 — 900 deg. C), become a new material: GLASS-FUSED-TO-STEEL with perfect anti-corrosion performance.

YHR has developed high-strength TRS (Titanium Rich Steel) plates specially produced for the Glass-Fused-To-Steel Technology, which can work perfectly with our glass frit and can eliminates the “Fish Scale” defect.

GFS Tank Manufacturing Procedure

1. Raw Material
High-strength TRS (Titanium Rich Steel) plates specially produced for the GLASS-FUSED-TO-STEEL Technology.

2. Laser Cutting
Bolt holes and nozzle openings cut by full-automatic laser cutting to ensure more accurate and efficient production.

3. Shot Blasting
All plates shall be shot blasted to SSPC SP-10/NACE2 (Near White Metal) to remove the surface oxide layer and oil pollution.

4. Bending
The radian of the rolled plates shall be sampling inspected by using the radian sample according to the tank diameter.

5. Glass Coating
High quality glaze from Germany and advanced automatic spraying coating technology as per AWWA D103 standard.

6. Firing
GLASS FUSED TO STEEL — firing in automatic tunnel oven at 800 °C to make glass and steel combined absolutely.

7. Inspection
Adopted highest standard of quality control system in the industry, Holiday test and coating thickness test every plates.

8. Packing
Non-abrasive packaging sheets shall be placed between each plate to eliminate sheet-to-sheet abrasion during shipment.

Fusion Bonded Epoxy (FBE) is an electrostatically applied coating system with superior coverage and uniform coating thickness. AkzoNobel high-tech RESICOAT R4-ES used on the internal surface combined with the ultra durable INTERPON D2525 on the external surface ensures high performance corrosion resistance for storage tanks and silos. The internal coating RESICOAT R4-ES is NSF/ANSI 61 certified for drinking water contact, and the internal contact surface of every panels are zero defects tested at 1100v before delivering to the clients.

FBE Tank Manufacturing Procedure

1. Laser Cutting
Bolt holes and nozzle openings cut by full-automatic laser cutting to ensure more accurate and efficient production.

2. Shot Blasting
All panels shall be shot blasted to SSPC SP-10/NACE2 (Near White Metal) to remove the surface oxide layer and oil pollution.

3. Bending
The radian of the rolled plates shall be sampling inspected by using the radian sample according to the tank diameter.

4. Pre-treating
Degrease and rinse, then drying with convected warm air.

5. Pre-heating
Before coat application all panels should be pre-heating to ensure coating quality and thickness.

6. Epoxy Coating and Green Curing
Electrically applied thermoset resin fusion bonded epoxy coating on the internal surface, then cured at a controlled temperature.

7. Polyester Coating and Crosslink Curing
Evenly applied ultra durable polyester powder coating on the external surface, then cross-link cured to yield durable finished product.

8. Inspection and Packing
Holiday test and coating thickness test to every panel. Non-abrasive packaging sheets to place between each plate.
