Shield Tunnel Steelwork | Galvanized Steel Components for Shield Tunnel Projects
Shield tunnels are damp inside with limited space, so steel parts need strong corrosion protection. K.C.F. can manufacture all kinds of in-tunnel steel components to your drawings and hot-dip galvanize them.
What Is Shield Tunnel Steelwork?
The shield method uses a tunnel boring machine to advance underground while assembling segments to form the tunnel, and is commonly used for MRT, sewer, power and telecom conduit projects. Once the tunnel is completed, steel components such as brackets, walkways, handrails, hangers and embedded parts are still needed inside. They remain in a damp underground environment for many years, and hot-dip galvanizing is a common corrosion protection method.
In damp underground spaces, the zinc coating is the steel's protective armor.
Key Features of Shield Tunnel Steelwork
Built for Damp Underground Environments
Hot-dip galvanizing slows corrosion even with long-term exposure to tunnel humidity.
Designed for the Tunnel Cross Section
Can be made to the tunnel's inner diameter, pipeline layout and construction drawings.
Custom OEM Manufacturing to Your Drawings
We can fabricate to drawings and specifications provided by the owner, designer or contractor, and can evaluate both small-lot and volume orders.
One-Stop Service from Fabrication to Galvanizing
Materials, cutting, welding and hot-dip galvanizing are handled together, reducing the time spent on transport and coordination between plants.
Typical Applications of Shield Tunnel Steelwork
- MRT shield tunnels
- Sewer and drainage tunnels
- Power shield conduits
- Telecom and utility tunnels
- Water transmission tunnels
- Shafts and cross passages
Why Choose Hot-Dip Galvanizing for Shield Tunnel Steelwork?
Steel exposed to rain, humidity and air pollution over time rusts easily, and corrosion resistance is the key factor in component durability.
Hot-dip galvanizing immerses steel in molten zinc, so the zinc coating bonds tightly with the steel and fully covers surfaces, edges and holes. Even if the coating is locally damaged, the surrounding zinc corrodes first to protect the steel. For shield tunnel steelwork, hot-dip galvanizing reduces the need for future rust removal and repainting.
K.C.F. specializes in hot-dip galvanizing, carrying out pretreatment, dipping and inspection in accordance with the relevant standards so every batch of components has consistent coating quality.
