Blast Doors
Product Information: Standard Pre-engineered ROLLC Blast Resistant Doors are based on the technical specific provisions issued by the Finnish Ministry of Interior. These doors are available in wide size range single and double doors with level of protection ranging from 1.0 bar to 18 bar peak reflected overpressure.

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.
Blast Resistant Doors & Frames
The DoD Minimum Antiterrorism Standards for Buildings is designed to protect DoD personnel from terrorist attacks. Whether retrofitting an existing building or building a new one there are minimum blast pressure requirements that all door assemblies must meet. The specific requirements depend on building location, type, and occupancy. The October 1, 2013 version of UFC 4-010-01 makes it clear that unless a door failure in response to the applied blast load does not pose a risk to occupants (i.e. the door is intercepted by a suitably strong wall before entering an occupied area) all doors must be evaluated for blast resistance at the applicable charge weights & standoff distances.
Rollc has an extensive blast resistant door & frame product line that was developed specifically for UFC 4-010-01 projects. Rolle teamed up with the University of Ottawa’s Hazard Mitigation and Disaster Management Research Centre to conduct an extensive research & development project involving over 55 shock tube tests, as per ASTM F-2927, of various blast door products in various configurations and sizes. Additional static pressure testing, as per ASTM F-2247, and finite element analyses were performed to develop software to verify blast door & frame performance for any charge weight, standoff, and level of protection scenario.
Where project requirements take us beyond the scope of the product line developed with the University of Ottawa’s Hazard Mitigation and Disaster Management Research Centre, Rolle engineering department has years of experience performing blast door & frame analysis for almost any imaginable charge weight, standoff, level of protection, and door & frame configuration.
Whether proven via testing or analysis, Rolle evaluates and selects blast doors & frames based on project specific requirements; this ensures that the end user benefits from lightweight and cost-effective blast doors & frames that use conventional hardware.
The petrochemical industry invests heavily in designing process plants to minimize the likelihood of accidental explosions. Although the probability of an accidental explosion is very low all buildings located within the range of accidental explosions are designed to be blast resistant. Other common industrial applications are flammable and/or pressurized materials storage and handling, paint booths, and ETO sterilization for medical and pharmaceutical products.
Rolle has worked with industry leaders BakerRisk and ABS Consulting to conduct a variety of open arena and shock tube tests on AMBICO blast resistant door & frame assemblies. In addition, Rolle has conducted many static pressure tests at our factory, all witnessed, validated, and reported on by lntertekTesting Services.
Where project requirements are outside the scope of tests that Rolle has conducted, our engineering department has years of experience performing blast door & frame analysis for almost any imaginable blast load response, and door & frame configuration.
Whether proven via testing or analysis Rolle evaluates and selects blast doors & frames based on project specific requirements; this ensures that the end user benefits from lightweight and cost-effective blast doors & frames that use conventional hardware where possible.
When specialty multi-point hardware is required Rolle chooses to supply this hardware factory installed. This adds value by ensuring proper installation of a critical structural component.
Fire ratings are increasingly being specified on blast resistant exterior openings for petrochemical projects; Rolle offers up to 5′ x 1 O’ singles and 1 O’ x 1 O’ pairs with a fire rating of up to 3 hrs.

Blast Proof Door
Rollc produces Blast Resistant Door with full range of sizes to meet project requirements for safety and security objectives. Providing extra protection against explosions and excessive force, our blast resistant openings meet or exceed the manufacturing and performance requirements.
Rollc range of bullet resistant doors covers various ranges (FB4, FB7) of different standards (EN1522 / EN1523, NIJ, UL572) to ensure providing required protection level for each location.
Blast Valve
Blast valves are used for protection of ventilation air intake and exhaust openings and airways high security areas. ROLLC blast valves are typically used in special applications that require high blast protection from both positive and negative phases of the blast.
