Rock Bolt Method "SP Leg Drill Method (≤3.0m)"

Active two-directional pressure injection for reliable full adhesion!

In areas where access is difficult and the boreholes cannot stand independently, the leg drill method using rope scaffolding has been widely used. In contrast, the "SP Leg Drill" actively employs "two-directional pressure injection," enabling the installation of permanent bolts up to 3.0 meters even in ground where the boreholes cannot stand independently. Additionally, this pressure injection can be applied for the repair of aging slope protection structures. 【Features】 - Economical short-length rock bolts for ground where boreholes cannot stand independently - Reliable anchoring achieved through pressure injection For more details, please contact us or download the catalog.

Twisted Bar Steel Lock Bolt "SN Twist Bolt"

It prevents the occurrence of voids on the back side and achieves good adhesion along the entire length of the bolt.

The "SN Twist Bolt" is a twisted rebar lock bolt that has been cold twisted from specially manufactured high-tensile deformed steel to further enhance its strength. When this product is inserted into a borehole filled with mortar, the spiral ribs and cross ribs rotate the mortar, improving the ease of insertion. As a result, it prevents voids from forming behind the ribs and joints, ensuring good adhesion along the entire length of the bolt. 【Features】 ■ Forms a surface shape that is easy to insert into boreholes filled with mortar ■ Effectively prevents the formation of voids between the mortar and the bolt ■ Adhesion performance with mortar is superior to that of deformed steel ■ Rolled threads based on JIS-B-0205 standard metric coarse threads *For more details, please refer to the PDF materials or feel free to contact us.
