Perforated metal offers a unique look that catches the eye and makes empty spaces seem less drab. In places where there might have been only a featureless expanse of unbroken metal, perforation provides visual punctuation. When coupled with other visual elements such as stripes or blocks, perforation can lend a sense of composition to areas that would otherwise be completely utilitarian. A visual field broken up by many small features is more optically interesting than a featureless field. Painting the metal a bright color can enhance this, giving the viewer a slight feeling of excitement. Design elements that create this feeling encourage people to talk, interact and feel ready to do something. If there is food nearby, a visually stimulating space helps people feel hungry. Visual elements simply feel more “up,” and those who see them tend to also feel that way. Perforated metal can be painted in bright, contrasting colors to impart a sense of animation to the space. Small, close perforations make the walls seem closer and can make a big space seem more snug, especially when the look is enhanced by interesting objects in the foreground. When pictures or other elements are hung on a perforated surface, make sure they are rather large or they will get “lost” in the busy background. If the pictures are large enough and less busy than the perforated background, the viewer’s attention will be drawn and focused on them. For areas where there will be much socializing and animated activity, break up perforated metal panels with stripes, wide bars or low-hanging drapes. This increases the sense of activity and has an effect on the viewer even if they are not consciously aware of it. From a builder’s viewpoint, perforated metal offers the advantage of lightness. Many metal sections used in building have more structural strength then they really need. Placing perforations in metal pieces leaves plenty of strength for most architectural applications while decreasing the weight of the piece. This makes installation easier and eliminates the need for additional support in some places. In both design and structure, perforated metal has much to offer, and is being used more in patio design and for areas such as roofing.
