Double Rib Sheet

The Durakolor Double Rib Roof sheet is a highly preferred product for both roofing and cladding applications, and it is widely recognized as the most commonly used profile globally. It boasts a unique design that enables it to withstand harsh weather conditions, including heavy rainfall.

One of its notable features is its exceptional load-bearing design, which allows for larger spacing between purlins. This not only enhances its structural integrity but also reduces the need for excessive overlapping. Moreover, it is available in lengths of up to 12 meters, further minimizing the number of required overlaps.

The sheet is offered in a variety of colors, and for larger orders, custom color options can be accommodated. Additionally, it is constructed with two square flutes, also known as ribs, which significantly enhance its strength. Furthermore, the inclusion of an anti-capillary groove ensures that water does not infiltrate through the side laps.

Durakolor Double Rib Roof sheets can be manufactured from different raw materials such as Bare Galvalume, Color Coated Galvalume, Stainless Steel, and Aluminum, providing versatility and options to suit various project requirements.
