Aluminium (BGL)
Colour coated Metal Roofing sheets have been used extensively by the construction industry throughout the world for nearly two decades because of its excellent corrosion resistance, aesthetic look, durability, wide ranges of colours. It has become the preferred material for a wide range of construction uses, particularly for roofing and cladding. Large crest with two parallel mini ribs between the crest makes the profile stronger which translates into long spanning capabilities. Thus the profile is most recommended for heavy rainfall intensity area.
