| STATUS: DRAFT This standard describes a universal way to describe a shape. = Intend = The intend is to offer a way to classify industry standard profiles, not limited to steel, based on shape only. The reasons for using this standard can be: * Shapes are described not depending on manufacturing characteristics such as "warm rolling". * Shapes are described not depending on function characteristics such as "beam". * The names are better suited for use in automation applications. * Naming is based on visible appearance like "Square" and "Rounded". * By prefixing the name with a standard institute and use a trailing general used profile designation, a global unique designation is created that is better understood. = Naming = The name is one or a combination of characters. * The first character is the main shape. Examples: "T-profile" and "Rectangular" * Subsequent characters are only designated if not corresponding to the expected default shape and or add extra shape complexity. This works like a sieve. The longer the code, the more complexity. == First character, main shape == The first character determines the basic shape. {{attachment:basic_profiles.svg|basic_profiles.svg|title=""}} The first row contains abbreviations: ||H ||Hexagonal || ||C ||Circular || ||S ||Square || ||R ||Rectangular || The second row is more obvious, the letter represents the shape. O stands for omega. |
