HWH Protective Structures Introduces Composite Blast Resistant Structure with Six Times the Protection of Steel Plate Systems

HWH Protective Structures LLC, a hazard resistant buildings development and manufacturing firm with access to the world’s leading test facilities, has introduced Blast Resistant Modules (BRMs) that set new blast, impulse and ballistics standards. The first in the world field repairable structures provide wind, seismic, fire and forced entry protection for industrial, military and education applications.

HWH Protective Structures LLC, a hazard resistant buildings development and manufacturing firm with access to the world’s leading test facilities, has introduced Blast Resistant Modules (BRMs) that set new blast, impulse and ballistics standards. The first in the world field repairable structures provide wind, seismic, fire and forced entry protection for industrial, military and education applications.

Widely used in military and petrochemical environments, hazard or blast resistant buildings are increasingly relevant to an expanded range of public and private sector applications, for protection against terrorist attacks; explosion, fire and hazardous materials; tornados, floods and earthquakes; and virtually any situation requiring exceptional building integrity. HWH Protective Structures’ modular approach brings a new level of protection to schools, hospitals and other public infrastructure; industrial and commercial sites such as refineries, chemical plants and bulk grain processors; plus government offices and fortified residences for concerned citizens. The technology adds the flexibility of building safe rooms or hardened areas within existing buildings, as well as new modular standalone structures, and has a patent pending on key components of the design.

As an Antiterrorism/Force Protection (ATFP) specialist, HWH Protective Structures has created a building system to withstand both high explosives (HE or ATFP) and vapor cloud explosions (VCE).

The BRM system combines proprietary steel alloy studs with custom interior and exterior sheathing, and an optional wall system upgrade adding up to UL 752 Level 10 ballistics resistance, compared to the more common level 8 rating. This performance was validated in simulations as well as real world testing at the University of California at San Diego (UCSD) Englekirk Structural Engineering Center (Dr. Gil Hegemier), and the Applied Research Associates (ARA) full-scale research and testing facilities in Pecos, Texas. Additionally the BRM has established ASTM E 413-04 ratings for sound protection; wind & seismic protection in accordance with EC 003-2012; 60 minutes of forced entry protection; and ASTM E-119-08 and CAN/ULC S101-07 ratings for 1-hour and 2-hour fire resistance.

HWH Protective Structures is a partnership between the Protective Technologies, LLC., blast and seismic resistant experts associated with UCSD; International Materials, Inc., the inventors of Sure-Board®; and Harrison, Walker & Harper, LP., an engineering, procurement and construction firm with a 125-year heritage. Details on capabilities, copies of third party validation reports and videos of live testing are available at http://www.hwhprotectivestructures.com and located on the media page.
