Featured as a critical component for safety harness kit, the minimal strength of the alloy steel D ring and aluminum D ring is 22.2KN. No matter it is alloy steel or aluminum D ring it is CE and ANSI and CSA certified and meet the CE standard EN362-2004, ANSI standard Z359.12-09 and CSA standard Z259.12-16. The D ring is widely used as dorsal, frontal and lateral attachment on fall arrest safety harness. Cooperated with positioning lanyard or/and energy absorber lanyard, safety harness D ring effectively guarantee the safety of the user. It has been exported to more than 85 countries and regions throughout the world in Europe, America, Mid-east area, Australia, Southeast Asia, Africa etc.
As a attachment for safety harness lanyard, the safety harness D ring is made of alloy steel or aluminum. Some D rings for special surroundings, such as insulated D ring and dielectric D ring, are plastic coated, which can offer a minimum 9kV dielectric resistance. The D ring differs from each other not only in material, but also in style and surface treatment. Zinc plated, polished; Zinc plated, matte and yellow zinc plated, matte are available for surface finish.
There critical steps to ensure the quality:
Ø Spectrographic analysis
Ensure proper metallurgy content of all raw materials.
Ø Proof load Testing
All safety harness connecting components are 100% proof loaded to 3600IBS/16KN.
Ø Ultimate breaking Load Test
Connecting and adjusting components are batch tested for ultimate breaking strength.
-Connecting components-exceed 5000lBS
-Adjusting components-exceed 4000lBS
