Aicher Steel Americas​ Strand Anchors

Aicher Steel Americas has been successfully manufacturing premium Strand Anchors in various length and sizes for the most demanding applications.

With one of the most sophisticated strand machines available, we are proud to offer domestic and non-domestic strand options to be used in the most challenging projects. From the initial design help to the final product, Aicher Steel Americas has established itself at the top of the industry.

With various approvals, from the City of LA to the California Transit Authority (DOT), Aicher Steel Americas Strand Anchors have been chosen to be the perfect solution for a variety of infrastructure projects.

Strand an­chors con­sist of three main com­po­n­ents: the an­chor head, a steel ten­don - di­vi­ded in­to the bond sec­tion and fre­e­length - and the grout bo­dy. The steel ten­don is con­struc­ted from a num­ber of 270K 7-wire pre­stres­sing strands.

Strand an­chors can be clo­se­ly matched to the re­qui­red loads by selec­ting the num­ber of strands, strand cross-sec­tion and steel gra­de. Long an­chor lengths can be pro­du­ced wi­thout joints.

• Shop drawing and engineering assistance to our customers
• Stressing equipment with up to date calibration available on rental basis
• Short lead time

Applications:

• Permanent Soil Anchor
• Temporary Soil Anchors
• Slope Surface Stabilization
• Foundations
• Temporary Support of Excavation 

The sys­tem is ea­sy to in­stall due to high an­chor fle­xi­bi­li­ty. Trans­por­ta­ti­on is ef­fi­ci­ent due to low space re­qui­re­ment for trans­port and sto­r­a­ge as an­chors are sup­p­lied coi­led up.
