Dimondek 400

This profile has been a favourite for many years with its high, narrow ribs and wide pans providing the opportunity for greater freedom of design.  This freedom is further enhanced by the ability to roll form Dimondek 400 on site enabling sheets of almost any length and eliminating the need for end laps.  These features combined with concealed fixing, which is common to all Dimondek profiles, makes Dimondek 400 an attractive and effective choice for your next project.
