What is a trapezoidal roof? What is a trapezoidal profile?
The profile is made up of a series of corrugations, each in the shape of a trapezium, (referred to as Trapezoidal Profile) which lap together side to side and end to end, making it very easy to cover varying areas of roof quickly.The profile sheets are typically coated steel, but can also be supplied in aluminium, and have mastic seals located in the end and side laps. Fixings are located normally through the 'pan' of the profile, rather than through the corrugation.Profiled roof sheets are normally best suited for finished roof pitches greater than 4°. They can also be used for barrel vault curved roofs in specific Elite Systems

Which roofing sheet is cheaper?
Galvanised steel sheets
These are carbon steel sheets coated with zinc, produced through a process known as continuous hot dip. Galvanised iron sheets are one of the most popular roofing materials in southern India. They are affordable, durable and easy to install. However, they are not suitable for all climates and can rust over time. If you live in a humid or coastal area, consider using aluminium or stainless steel instead. Sheets of galvanised iron are available in varied gauge thicknesses and sizes. Zinc with aluminium or zinc coatings was used on this sheet to provide anti-corrosion treatment.
Metal roofing sheets
Metal roofing sheets are eco-friendly roofing solutions, as they can be recycled. Generally, they are made of tin, zinc, aluminium and copper. Metal roof sheets are similar to corrugated roofing sheets in terms of the composition but they have fewer curves. You will find numerous styles, textures and colours in this class of roofing sheets and can make a choice between contemporary or traditional designs for your home.Advantages: They are easy to install and can be customised for building rooftops, depending on factors like durability, price, energy efficiency and longevity. Roofing panels made of metal can withstand extreme weather conditions like heavy rains, snow and even fire. They are also pest-resistant and are preferred, owing to their longevity and durability. Metal roofs are excellent insulators and are widely used in garden buildings, garages, backyards, household cladding and industrial roofs.
