This mounting bracket D ring is made of hot forged one body rather than welding ring.This give a lot of loading factor The material of the mouting bracket tie down is high carbon steel or alloy steel or stainless steel .After forged,can do heat treatment to make it more harder and more strong .Then do sand blasting and griending the cutting line .Thi process make the cost a little higher than non griended D ring. Then weld on the mounting bracket .This strength can reach G40 or G80 .Surface is always hot dip galvanized or color painted
Applications of D-rings include:
● For light loading applications such as clothing and luggage, D-rings made of plastics such as nylon may be used.
● Commonly, at the end of a tow-rope or chain, to allow one to create a bow around an item or part of an item that is being towed by a vehicle. They are commonly used with a chain to tether a boat to a dock or tree when it is being moored.
● On breathing sets and scuba divers' buoyancy compensators
● A bit ring used on the bit of a horse.
● A type of carabiner.
● A part of a saddle
● A type of ring binder.
● To attach a leash or tag to a dog collar or dog harness.
A D-ring is an item of hardware, usually a tie-down metal ring shaped like the letter d used primarily as a lashing point.The term is found interchangeably spelled in different forms, such as: Dring, d-ring or even Dee-ring.A D-ring may be used at the end of a leather or fabric strap, or may be secured to a surface with a metal or fabric strap; though there are D-rings with a middle body designed to be welded to steel. Ideally, a D-ring swings freely after it has been secured. D-rings may vary in composition, geometry, weight, finish and load (rated) capacity. Though there are differences, a weld-on pivoting link is commonly called a D-ring.
