Blast proof doors are essential in buildings that are at risk of intentional blast attacks such as terrorist attacks, or accidental blasts. A securely closed blast resistant wall panels will provide vital protection to life, infrastructure, and assets.
In an ever-changing world where safety is paramount, QMI proudly presents a range of Blast and Gastight Doors that set the standard for protection. These doors are meticulously designed to withstand the devastating forces of explosions, offering unparalleled safety for various applications. Whether it’s a government installation, industrial site, or commercial space, QMI Doors delivers the security and peace of mind you need.
The ASCE has specified guidelines for the design of blast resistant buildings in petrochemical facilities. These guidelines divide the blast door operation into four categories.
Category 1 – The door still has to be operational after a blast event. This is for example necessary when there is a risk of another blast and the door is a primary exit of the facility.
Category 2 – With this category the blast door still has to be operational after a blast event, but can have significant damage. These blast doors has to be operational to prevent entrapment of personnel. The ductility ratio is between 2 and 3 for this type of doors. The recommended edge rotation is equal to or less than 2.0 degrees.
Category 3 – The blast doors in this category does not have to be operational after a blast event. No major structural failure of the panel, restraining hardware system and frame is permitted. For this category the ductility ratio is in the range of 5 and 10, the edge rotation has a maximum of 8 degrees.
Category 4 – Finally there is the fourth category. In this category the door also not have to be operational after a blast event and outward rebound force and resulting hardware failure is acceptable.
QMI Blast and Gastight Doors are the ultimate choices for those who refuse to compromise on safety. With the ability to withstand blasts across Category 1 to 4 and meeting the highest gastight standards, QMI sets the standard for protection.
