BLAST DOOR

Welcome in our Blast Door Expertise

Blast protection is essential in buildings that are at risk of intentional blast attacks such as terrorist attacks, or accidental blasts such as petrochemical accidents.

A securely closed blast resistant door will provide vital protection to life, infrastructure, and assets.

It is important for People to understand about Blast Doors so that they can incorporate them into their health and safety procedures. Blast attacks can have a tremendous impact on staff, building, business, and need to be fully understood before installed.

Sòphia High Tech manufactures Blast Resistant Doors from a variety of materials, such as aluminium, concrete and timber. For high-level blasts, it is best to use steel.

Steel has three times the tensile strength of aluminium.
It is more resistant to expansion, as it bends into the building and absorbs the pressure. Thus, providing longer durability and minimizing hazards.
Incorporates fire resistant qualities; it has a low transfer of heat, and a high melting point.
Can sustain a particularly high level of pressure waves.

Design, Development, Manufacturing, Assembing, Validation, Shipping, Insallation and Qualification by Sòphia High Tech.

Sòphia High Tech is responsible for the Design, Development, Manufacturing, Assembly, Validation, Transportation, Installation and Qualification of Blast Resistant Door, AntiExplosion, AntiBurglar and AntiMissile.

Blast doors need to be tested (physically or by means FEM Simulation) to determine their performance level under blast load conditions. There are many standards depending on different Country’s testing regulations, the time the door withstands, structural damage, glazing, hazards and so much more.

Ratings tend to fall into categories under ASTM, GSA, PIP, DMG, CPN, UFC and ISO. In Sòphia High Tech, Design and Manufacturing phase is carried out according to the Customer Requirements and US Standards: UFC, USACE, DOD.

Explosion and Fire Containment

The most common function of a blast door and its surrounding walls is blast containment. In this application, the door will remain fully intact and ensuring the blast is fully contained. During testing, our doors performed to category I, meaning that the door remained closed post-blast and was still fully operable – important should the area required quick evacuation.

The storage of munitions requires a dry, temperature-controlled environment. We design to meet these requirements by using door set insulation and purpose-specific seals to prevent sweating and cold transfer from the external face of the door to the internal face. This ensures a stable environment for contents of the building whilst maintaining the required level of blast containment.

Design Methodology

The design of a blast door starts by the static seated and unseated pressure, as defined by the Customer. The door leaf designed to take the seated blast pressure and remain in the elastic range. The door hinges (or the sliding kinematic mechanism) and shoot bolts and their component parts are designed to take the unseated blast pressure.

The dynamic peak blast pressure, impulse and duration is also defined by the client as the required response criteria e.g. Class I (elastic) or Classes II, III or IV (plastic).

SDOF Numerical Analysis

The door leaf designed for the dynamic blast load using a single degree of freedom (SDOF) numerical analysis such that the response (leaf deformation) is within the client defined limits. The door hinges, shoot bolts and their connections designed for the rebound forces determined by the SDOF analysis.
