GFS Mining Silos: Corrosion-Resistant and High-Efficiency Bulk Storage Solutions for the Global Mining
Industry
The demands of modern mining operations are extensive, requiring safe, durable, and efficient storage solutions for
minerals, ores, aggregates, and chemicals. In harsh environments where corrosion, abrasion, and extreme weather
prevail, traditional carbon steel or concrete silos quickly deteriorate. To meet this challenge, Shijiazhuang
Zhengzhong Technology Co., Ltd (Center Enamel)—a global leader in Glass-Fused-to-Steel (GFS) technology—
has engineered its line of GFS Mining Silos, designed to combine sustainability, strength, and cost efficiency for long-
term operational excellence.
What Are GFS Mining Silos?
A GFS Mining Silo is a modular, bolted steel structure made using Glass-Fused-to-Steel technology, where molten
glass and specially formulated steel plates are fused together at temperatures between 820°C–900°C. This high-
temperature process permanently bonds the materials, producing a hybrid composite that combines the mechanical
strength and flexibility of steel with the inert, corrosion-resistant properties of glass.
The result is a seamless storage system capable of withstanding aggressive chemical environments, abrasive ores,
and extreme operational conditions found in mining.
The Science Behind GFS Technology
The Glass-Fused-to-Steel (GFS) process begins by applying multiple layers of silicon-rich glass frit to both sides of a
shot-blasted steel plate. When the plate is fired in a kiln, a powerful molecular bond forms between steel and glass,
creating a non-porous, glossy, and chemically stable surface.
This provides several key physical advantages:
High hardness (6.0 Mohs) for abrasion resistance.
Adhesion strength ≥ 3,450 N/cm², forming a permanent chemical bond.
Coating thickness of 0.25–0.45 mm, delivering superior protection to the substrate.
pH resistance from 1 to 14, suitable for storing acidic or alkaline substances.
Gas and liquid impermeability, eliminating contamination or leakage risks.
This unique construction technique positions GFS silos as the ultimate choice for mining production, ore refining, and
industrial material storage.
