Safety hooks are usually made of stainless steel, alloy steel or aluminum alloy.
Steel safety hooks are hard and heavy in texture and are suitable for connecting anchor points or sharp metal devices such as safety straps and descenders.
The breaking load of aluminum alloy hook is not inferior to that of steel products. Aluminum safety hook is relatively light in weight and suitable for connecting various equipment of personal protective equipment and carrying multiple spare parts.
But the aluminum alloy is less resistant to cutting, use should avoid hanging with other sharp metal hooks.
