A shell material breakdown for crews who need to know what's actually protecting their head
The fiber metal hard hat gets its name from an older manufacturing process that laminated resin-impregnated fiber into a rigid, high-heat-tolerant shell, a construction style still produced today by Honeywell under the Fibre-Metal brand. Unlike molded thermoplastic or polycarbonate hats, a fibre metal hard hat is built for climbing, welding, and high-heat environments where a standard cap-style hat falls short. This guide breaks down what fiber metal shells are made of, how they stack up against thermoplastic and polycarbonate options, and which style fits your crew's jobsite conditions.
