Steel shelters are mobile installations designed to provide immediate protection against external threats, such as rocket and mortar fire. They are made of strong and durable steel, which allows them to withstand blast and shrapnel loads, thus ensuring the safety of those inside. The shelters are designed so that they can be moved and placed quickly and easily in different locations, depending on the operational or civilian need. They come in different sizes and configurations, adapted to varying numbers of people and for various purposes, such as protecting civilians in public spaces, workers on construction sites, or soldiers in the field. In addition, the shelters are equipped with ventilation and lighting, and allow for relatively comfortable stay during an emergency. Installing steel shelters is part of efforts to improve personal and community protection, and is recommended by the competent authorities as an effective solution for immediate protection in emergency situations.
