The everyday box profile
Dragon IT4 roofing sheets are a box-profile roofing material available in a variety of colours. The trapezoidal shape, with box crests and valleys, makes IT4 suitable for both roofing and wall cladding.
Each sheet has four troughs and five ribs. The valley (trough) is wider than the crest (rib) and is stiffened with two 25 mm strips, giving the sheet strength without extra weight. IT4 can also be factory-cranked into curves with a minimum radius of 400 mm for curved roofs and canopies.
