Overview
Concealed-fix roofing
Surelok 695 is Roofco's concealed-fix roofing system. Hidden fixings protect fasteners from weather and thermal movement, producing a clean surface with no exposed hardware. The 2° minimum pitch makes it suitable for low-slope commercial and industrial roofs where conventional corrugated profiles cannot be used.
