Anti-slip coefficient of high strength bolts adjoining steel sections

Home/Certificates and reports, ZINGA/Anti-slip coefficient of high strength bolts adjoining steel sections

Project Description

GB 50017-2003 Code for design of steel structures
GB 50205-2001 Code for Acceptance of Construction Quality of Steel Structures

In Octobre 2005, ZINGA coated plates have been tested according GB 50017 and GB 50205 to assess the slip friction coefficient (µ) of high strength bolts adjoining steel sections.

The results demonstrate that ZINGA coated surfaces of high strenght bolts have increased friction (compared to bare steel or galvanised steel) with results of µ between 0.5 and 0.7. This is beneficial for construction.
