The Only True Inverted Box Rib

BR-6™ offers an excellent balance of performance and economy

BR-6™ has a bold angular appearance and makes it a very attractive choice as it has many advantageous characteristics such as its wide 960 mm cover width, strength to weight ratio, that provide optimum load span consistency, and the broad flutes ensures excellent drainage

BR-6™ can be laid in 1 of 2 configurations - narrow flute out, the standard manner, or broad flute out, commonly used for cladding of vertical surfaces. These provide a very different aesthetic, and can be combined, creating the appearance of two different profiles
