The stay cable and U-bolt clamps are coated with grease.
Figure 3 shows the anchorage region.
![Anchorage region.](bridges/cable-stayed-bridges/bridge-6/4-stay-cables-anchorage-connection.jpg)
The stay cables are connected to the RC block by turnbuckles and additional cables, which are terminated by U-bolt clamps. All steel elements are coated, and two coated turnbuckles are shown in figure 4.

The coat layer is about 5 mm thick.
Figure 5 shows the additional cables in the RC block region.

The additional cables are embedded in the RC block, and non-coated regions near the concrete surface are noticeable.
