Swellex rock bolts
In most cases, TITANEX bolts are designed for temporary support for 2-3 years. So no special surface treatment is needed. However, when a longer service life is required, the zinc-galvanized steel pipe is selected because it has a rust-preventing ability comparable to that of stainless steel, and is less expensive.
