Optimized Performance

Higher load performance at the same embedment depth. 
The new HST3 presents two embedment depths that make design more versatile. Significantly higher loads can be achieved at the same embedment depth and application on thinner slabs is approved.

Design Flexibility

Smaller edge and space distances with improved design and installation flexibility. 

Minimum edge and spacing distances are possible thanks to HST3’s optimizes coating throughout the anchor, which reduces expansion forces in the system. No concrete splitting may occur when placed close to edge and another anchor.

Extensive Concrete Grades
