IBR roof sheets are a type of roofing profile commonly used in construction. “IBR” stands for “Inverted Box Rib,” referring to the shape of the profile of the roofing sheet. IBR roof sheets are typically made of Zinc-aluminium, Aluminium, and galvanized steel or other metals and polymers. They feature a series of raised ribs running along their length, which are crucial for the selection of the appropriate roofing screws. These ribs not only provide additional strength and rigidity to the roofing sheets but also play a significant role in the compatibility with roofing screws, making them suitable for use in a variety of applications, including residential, commercial, and industrial buildings.
