Coulomb S Series

1. The properties of anchor bar can meet the international standard
2. The elongation of anchor bar is not less than 12%
3. The mechanical properties of coupler and nut can reach to the theoretical ultimate load of anchor bar

R32 SDA Bolt is a kind of self drilling hollow anchor bolt. It consists of hollow anchor bar, drill bit, coupling, packer, plate and nut. It combines grouting and drilling together and adapts several construction situation and different geological conditions.

Function:
1. Instead of the traditional mortar anchor bolt, it used for radial reinforcement.
2. It can be used to reinforce unstable slope.
3. The foundation reinforcement of construction.

Features:
1. It can solve defects that unfilled grouting of traditional mortar anchor bolt during the construction and can’t grouting with pressure.
2. The operation is simple, cost is low, construction is convenient and efficiency is clear.
3. It can realize grouting with pressure and reform foundation surrounding rock conditions.
