The ARCSLOT Aluminium Top Cap Profile is a premium extruded aluminium capping system engineered to cover, clamp, and seal the top edges of polycarbonate multiwall sheets and UPVC/metal tile-profile roofing sheets.

Its 3-leg underside cross-section ensures strong grip, uniform alignment, and leak-proof overlap when mounted over aluminium/steel base profiles in slab roofing, skylight glazing, and tiled roof finishing applications.

Made from architectural-grade aluminium, this section supports natural expansion and contraction of polycarbonate sheets without cracking, while delivering high durability, corrosion resistance, and clean aesthetics for long-term outdoor use.
