DANKAT® hollow bars are fully threaded self-drilling system that allows drilling into loose or collapsing drill holes with a system combined of grouting and anchoring simultaneously with no need for casing. DANKAT® hollow bars are made of high-grade steel and designed to meet ASTM and EN Standards. DANKAT® bars are both available in R thread and T thread, selected raw material and a fully automated production system make the DANKAT® SDA system exceed the quality and proof of Yield and Tensile load.
DANKAT® Steel bars are regularly tested in-house and by third-party accredited worldwide testing laboratories to ensure consistent quality and defect-free products.
Ductility is a measure of the degree to which material can undergo plastic deformation before breaking. All DANKAT® Bars have elongation > 12% and Agt > 8%.
With continuous threads, Our SDA system ensures cutting and coupling at any length.
DANKAT® bars can be drilled into loose or collapsing soil without the need for a casing to support the borehole.
