Our solid steel Classic-ISO-PLUS profiles are equal leg profiles that, like Classic-ISO profiles, are ideal for renovation projects by combining a respect for architectural heritage and meeting today’s highest technical standards. Classic-ISO-PLUS profiles are even stronger than Classic-ISO profiles because they are deeper, making them perfectly suitable for doors and exceptionally large facades.
