Alumasc GX - Joggle Box Pressed Aluminium 90 Degree External Angle

/F Variations available in Joggle, Smooth, and Moulded profiles.

The Alumasc GX Gutters range is a high-capacity pressed aluminium system designed for both traditional and modern applications, especially where maximum flow performance is required. Gutters are supplied in 3m lengths and are compatible with a full range of fittings including extra union clips, top straps, stop ends (left and right-hand internal), 90° and 135° angles (internal and external), and running outlets. Each component has been developed to ensure ease of installation, reliable jointing, and long-term durability.

GX Gutters are fully compatible with Alumasc’s Skyline fascia and soffit systems, allowing for a seamless architectural finish. They can be installed either exposed or concealed, providing flexibility for different building designs. Manufactured from pressed aluminium, the system is lightweight, corrosion resistant, and easy to handle on site.

The range is designed to accommodate thermal movement at every joint, ensuring performance and longevity in varied climates. With a life expectancy of up to 40 years in rural and suburban areas, and up to 25 years in industrial or marine environments, GX Gutters provide a long-lasting alternative to PVC systems while offering higher capacity and superior strength.

All products are available in a plain mill finish for on-site painting, or with a factory-applied BBA approved polyester powder coating in 26 standard colours, with additional BS or RAL shades available to order.
