The 1591 Mild Steel Stormproof Butt Hinges are purpose-built for weather-sealed windows and exterior joinery, providing enhanced durability and resistance in harsh outdoor conditions. Made from heavy-duty mild steel, these hinges feature a fixed pin for secure installation and long-term reliability.

Designed to accommodate outward-opening casement windows, the stormproof profile allows the sash to close snugly into a rebated frame, offering improved protection against wind and water ingress. The butt hinge structure ensures a smooth and stable pivot motion, even under frequent use.

With their functional design and robust construction, these hinges are ideal for both residential and commercial projects, especially where weather resistance, strength, and simple installation are required.
