Blast Doors

  Structural configuration of ROLLC custom doors may be steel door with homogenous steel plate or I-beam stiffened steel plate structure. Concrete arch doors are recommended for high pressure load for large door openings in applications where the door jambs are capable of receiving the reaction forces from the door arch. Sliding blast resistant and gas tight doors can be provided for applications where space constraints prevent the use of swing doors. ROLLC has over 10 years experience in supplying custom doors with extremely demanding requirements. Projects successfully completed incorporate doors with triangular or bilinear impulse load up to 50 bar with 100 percent rebound resistance, combined blast resistant and air-tight doors providing zero leakage up to 2000 Pa pressure difference across the door as well as very large hinged concrete arch doors all having numerous additional functional requirements. Blast resistant steel door designed for 783psi-ms average impulse load that may be exerted on either side of the door. The applicant Specify your requirements. Successful undertaking of a special door project implies that the door manufacturer is capable of working together with the architect and structural designer of the facility from the very beginning. This is imperative in order to reserve sufficient space for the door and its embedded components and to design the wall reinforcement properly to receive the substantial reaction forces transmitted from the door.
