What are angle bracket accessories typically made of

Angle bracket accessories can be made from a variety of materials, 

including metals like steel, aluminum, and stainless steel,

as well as plastics such as nylon or polypropylene. 

The choice of material depends on factors such as 

the application requirements, load capacity,

and environmental conditions. For example, in corrosive

or high-temperature environments, resistant materials 

such as stainless steel or heat-resistant alloys may be preferred.

In contrast, in applications where weight and cost are a concern, 

lighter materials such as aluminum or plastic may be used.
