Classic-ISO

The world’s slimmest

Our Classic-ISO massive steel profile lets you explore a vintage, refined look resembling the hot rolled steel, equal leg profiles from the beginning of the 20th century. Classic-ISO profiles are ideal for renovation projects and can have both interior and exterior glazing. They meet all of today’s highest technical standards while respecting any architectural heritage they may adorn.
