Towards further high support capacity: Environmentally friendly low-dust high-friction construction method "At Column"
The ATT column, which started as a friction pile for soft ground, has seen an increase in adoption as a tip-supported pile due to improvements in drilling capacity through the introduction of high-torque machinery. By incorporating high-tensile steel pipe STKT590, the "pile material capacity," which was often insufficient when used as a tip-supported pile, has significantly increased, enabling more economical foundation design compared to conventional ATT columns. 【Features】 ○ Exhibits large vertical and horizontal forces ○ Demonstrates high pull-out resistance For more details, please contact us or download the catalog.
