Bolted Storage Tanks for Dry Bulk - Efficient Solutions from China's Leading Suppliers and Factory
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 projects like concrete water storage containers, bolted steel tanks provide 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.
Features of Glass Fused to Steel Tanks
- Fast installation and short construction period
- Excellent anti-corrosion properties
- Low construction environment requirements
- Strong temperature adaptability
- Wide range of applications, seamlessly integrated to form assembled reactors
- Aesthetically pleasing appearance
- Flexible for relocation, expansion and recycling
- Simple maintenance and service life in excess of 30 years
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) tank is a bolted storage tank constructed by fusing high-strength TRS (titanium-rich steel) plates with enamel at high temperatures, forming a highly inert inorganic glaze layer. This combination delivers exceptional corrosion resistance, durability, and a smooth inner surface suitable for both liquid and dry bulk storage.
Why are GFS bolted tanks suitable for dry bulk material storage?
GFS bolted tanks solve the three core challenges of dry bulk storage: moisture absorption, material adhesion, and surface abrasion. The enamel surface is zero-permeability, ultra-smooth, and highly wear-resistant, keeping stored 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 sintered at high temperature provides outstanding hardness, acid and alkali resistance, and long-term durability that far outlasts conventional painted or galvanized steel tanks.
Can GFS bolted tanks be relocated or expanded after installation?
Yes. One of the key advantages of GFS bolted tanks is their modularity. They can be expanded by adding additional steel plate layers when more capacity is needed. If a facility is relocated, the tanks can be fully dismantled by removing bolts and reassembled at a new site, preserving the full asset value—an option not available with concrete 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 sealant, and self-locking bolts. The steel plates are overlapped, bolted together, and sealed to create a watertight, airtight structure that is both structurally robust and easy to assemble or disassemble.
How do GFS bolted tanks compare to traditional concrete storage structures?
Compared to traditional concrete structures, GFS bolted tanks offer faster installation, lower construction environment requirements, superior corrosion resistance, and greater flexibility for expansion or relocation. They are also more cost-effective over their lifecycle due to minimal maintenance needs and the ability to be reused at different sites.
