What Are Bolted Steel Tanks?
Bolted steel tanks are modular storage tanks assembled on-site using high-strength steel panels and bolts. Unlike welded tanks, bolted tanks provide:
When enhanced with Glass-Fused-to-Steel technology, these bolted steel tanks become highly resistant to corrosion, impermeable to liquids, and capable of long-term service in harsh environments.
Glass-Fused-to-Steel Technology
Glass-Fused-to-Steel (GFS) technology involves firing molten glass onto hot-rolled steel plates at temperatures ranging from 820°C to 930°C. This process creates a metallurgical bond between steel and glass, providing:
