China Suppliers and Factory of Bolted Storage Tanks for Efficient Dry Bulk Material Storage
Description
Using bolted tanks (especially GFS bolted tanks) for storing dry bulk cargo essentially involves applying a high-standard, corrosion-resistant container originally designed for liquids to the field of solid bulk materials. This technology solves the problems such as moisture absorption & caking, wall adhesion & clogging, as well as abrasion & corrosion in dry bulk storage.
Compared with traditional engineering project like concrete water storage container, bolted steel tanks provided a more efficient and cost-effective solution, ensuring safe and efficient transportation and storage.
The Glass Fused to Steel (GFS) tank is a kind of bolted storage tank made from two materials: glass and steel. High-strength TRS (titanium-rich steel) plates and enamels are perfectly fused at high temperatures to form a highly inert inorganic glaze layer.
Material Characteristics of Glass-Fused-to-Steel Tanks
🔩 Low Carbon, High Strength, High Titanium
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.

Products Advantage
The reason why GFS bolted storage tanks are used for dry bulk storage is that, with their enamel surface featuring high hardness, high smoothness and high sealing performance, they precisely solve the three major problems of dry bulk materials: fear of moisture, adhesion and abrasion.
-
🧹
The enamel surface is smooth with extremely low surface roughness and a small friction coefficient. Materials hardly adhere under gravity, achieving a self-cleaning effect and ensuring smooth discharge.
-
💧
The enamel layer is a glassy material with zero air permeability. Acting as a dense glass bottle wall, it completely blocks the penetration of rainwater and humid air, keeping the materials inside the tank dry at all times.
-
⚙️
The enamel layer is sintered at high temperature, featuring high hardness and excellent wear resistance. It is also acid and alkali resistant, capable of resisting chemical corrosion from materials and protecting the substrate from damage.

LIDA's glass fused to steel (GFS) storage tanks are composed mainly of enamel panel, special sealant and self-locking bolts, etc. The steel plates are overlapped, bolted together and sealed with high performance seals. They are easy to be installed with a short construction period and simple to maintain. When factory capacity needs expansion, modular tanks can be heightened by adding steel plate layers. If the plant is relocated, they can be dismantled and rebuilt off-site by removing bolts, thus preserving asset value—something that cannot be achieved with concrete structures.
Frequently Asked Questions (FAQ)
❓ What is a Glass Fused to Steel (GFS) bolted storage tank?
A Glass Fused to Steel (GFS) bolted storage tank is a type of modular tank constructed from high-strength TRS (titanium-rich steel) plates coated with an enamel glaze layer. The glass and steel are fused together at high temperatures, forming a highly inert, corrosion-resistant inorganic surface suitable for both liquid and dry bulk storage.
❓ Why are GFS bolted tanks suitable for dry bulk material storage?
GFS bolted tanks are ideal for dry bulk storage because their enamel surface offers high hardness, exceptional smoothness, and zero air permeability. These properties directly address the three main challenges in dry bulk storage: moisture absorption, material adhesion, and abrasion — keeping materials dry, free-flowing, and protected from chemical corrosion.
❓ How long is the service life of a GFS bolted storage tank?
With proper maintenance, GFS bolted storage tanks have a service life in excess of 30 years. The enamel coating is sintered at high temperatures, giving it outstanding wear resistance, acid and alkali resistance, and long-term durability that far surpasses conventional steel or concrete structures.
❓ Can GFS bolted tanks be expanded or relocated after installation?
Yes. One of the key advantages of GFS bolted tanks is their modular design. Tank capacity can be increased by adding additional steel plate layers. If a facility is relocated, the tanks can be fully dismantled by removing the bolts and reassembled at a new site, preserving asset value — which is not possible with concrete storage structures.
❓ What are the main components of a GFS bolted storage tank?
GFS bolted storage tanks are primarily composed of enamel panels, high-performance special sealants, and self-locking bolts. The steel plates are overlapped and bolted together, then sealed to ensure a watertight and airtight structure. This design makes installation fast, maintenance simple, and the overall construction period significantly shorter than traditional concrete tanks.
❓ How do GFS bolted tanks compare to traditional concrete storage structures?
Compared to traditional concrete storage structures, GFS bolted tanks offer a more efficient and cost-effective solution. They require lower construction environment standards, can be installed much faster, are adaptable to a wide temperature range, and offer superior corrosion resistance. Additionally, their modular nature allows for easy expansion, relocation, and recycling, making them a more flexible long-term investment.
