S650 is a natural development of the Macalloy bar systems, providing a high-quality, high-strength, fully-threaded stainless steel bar for use in geotechnical and concrete applications.
S650 combines the benefits of Macalloy coarse thread with the high durability and performance of stainless steel. It is available in sizes from 16mm to 50mm, ensuring that the full range of applications are covered.
The bar performs equally well as a rock bolt, soil nail, holding down bolt or mini pile.
Manufactured from high-strength stainless steel with a minimum characteristic yield strength of 650N/mm2, it is available in 316. The coarse thread has exceptional bond characteristics, which combine with the full-strength nuts to provide a high-capacity anchor system.
The durability of stainless steel is well-documented, Macalloy Stainless S650 really is a ‘fix and forget’ solution.
Macalloy’s unique manufacturing facilities allow this bar to be produced in standard 6m lengths. However, longer lengths may be available on request.
