Compared with traditional expansion anchors, concrete self-tapping anchors not only have advantages in performance, but also have obvious gaps in construction efficiency. Concrete self-tapping anchors only need 3 steps: drilling-cleaning-installation and fastening, while traditional expansion anchors need 6 steps: drilling-cleaning-removal-embedded parts-installation- -Fastening.
(According to the experiment with M10 as the experimental object)
Leaving aside other gaps, the construction efficiency has been doubled. Make construction more efficient and faster, and save labor costs.
