"Over 85 percent of all U.S. nuclear power plants are protected by Delta vehicle barricade systems," attests Greg Hamm, Delta Scientific vice president of sales and marketing. "Delta Scientific systems protect the U.S. Capitol and other Washington landmark buildings, high-rise office buildings, Buckingham Palace, corporate facilities, the Singapore parliament, power and water infrastructure locales, military bases and facilities for all four U.S branches, petrochemical plants, European castles and the private homes of celebrities and influential people."

Designed specifically for use by the U.S. Navy, U.S. Department of State, U.S. Agency for International Deployment (USAID) and for U.S. Army checkpoints in Iraq for initial fast deployment, the totally self-contained Delta Scientific MP5000 High Security Mobile Barricade System is towed into position and controls vehicle access within 15 minutes. Since their inception, they have been used in high profile events such as the 2012 GOP and Democratic conventions and the resulting Inauguration. They have also protected world leaders at G20, Nuclear and NATO Summits. Only last September, they defended the Pope on his visit to the United States. They are very popular at leading universities during events in which traffic must temporarily be re-routed.

Penn State University uses seven of these barriers for home football games and special events. Like similar applications at the University of Michigan, Ohio State and others, PSU is able to quickly deploy these barriers at strategic sites around the facility. After the event, they are quickly knocked down and towed to another location.

Besides mobile barriers, Delta is also one of the world's largest manufacturers of fixed barriers. Delta barricades at the United States Consulate in Herat, Afghanistan, stopped a bomb-laden car and SUV from penetrating the entrances to the facility. Delta barricades at the United States Consulate in Peshawar, Pakistan, also helped retain the attackers, limiting casualties.

Transportation hubs including Los Angeles Airport, San Francisco International Airport, the union Pacific Railroad and other airports and major transportation centres employ Delta barricades, bollards and crash gates to defend passengers, employees, property and other transportation infrastructure facilities. Delta bullet resistant level 4 booths are installed for California's Ontario Airport. At LAX, crash gates protect the tarmac. To host 3 million cars per year, the Minneapolis/St. Paul International Airport has 18 Delta parking/cashier booths handling its parking capacity of 13,000 spaces.

Delta bullet-resistant Level 4 booths currently protect the Pentagon in Washington, DC as well as California's Ontario Airport and the U.S. embassy in Cairo. Fifty custom-design bullet-resistant Delta guard booths are now used at the San Ysidro Landed Port of Entry (SYLPOE), the busiest land port in the world. Located between San Diego in the USA and Tijuana in Mexico, the port processes an average of 50,000 northbound vehicles per day.
