The choice of trapezoidal sheet for the façade of a house, garage or hall is based on the building's appearance, the spacing of the substructure and the wind load. Check whether the profile suits the proportions of the whole façade, especially on a small garage and a large hall. Durability also depends on thickness, coating, fixings and water drainage. Distinguish between roof and façade versions and plan trims around windows, at the plinth and at corners. Colour alone is not enough; perception also depends on the width of the ribs and their rhythm.
