Special-sized doors. In addition to standard-sized fire- and blast-rated door types, InterDam offers project-specific solutions in accordance with your requirement. When extremely large openings must be closed for new-builds or refurbishment jobs, several door options can be considered, such as large removable panels, panels including single/double doors and doors with top panels. Project design statements or approvals by third parties can be arranged providing safety certification of these doors. Contact us for more information!
