Hard hats are classified into two types based on their brim style, full brim, and cap style. Full brim hard hats provide 360-degree protection from falling objects and other hazards. Cap style hard hats offer a narrower range of protection but are lighter and more comfortable to wear for extended periods.

Hard hats are typically made of a durable plastic or composite material, such as polyethylene or fiberglass. These materials are strong and lightweight, providing excellent protection against impact and penetration.
