Product Q&A
Q:What materials are used for the expansion shell and rock anchor bolts?
A:
The expansion shell is made of carbon steel, while the rock anchor bolts are made of cast iron.

A:
The bolts have a diameter between 20 mm and 25 mm, with lengths ranging from 1 meter to 4 meters.
Q:How does the expansion shell anchor work?

A:
The hole length should be at least 100 mm longer than the bolt to prevent the bail from being dislodged.
