When the royal family of Great Britain needed higher security at two of its residences, it was a Palmdale company that got the call. Delta Scientific Corp. last month replaced anti-vehicle attack posts – also called “bollards” – that had been outside Windsor Castle for 10 years with a new set. The bollards are strong enough to withstand a hit from a 15,000-pound vehicle going 30 miles per hour. When struck, they can crack an engine block. “We have barrier and bollard systems that have been in the field for over 20 years,” said Greg Hamm, vice president of sales and marketing for Delta Scientific, a privately-held, family-operated business. Windsor Castle has been home to the English and British monarchy since the 11th Century and is the longest occupied palace in Europe. Delta Scientific also has its security bollards installed at Buckingham Palace, the London residence and main workplace of the royal family. Delta Scientific was founded in 1974 by Harry Dickinson and has installed more than 60,000 of its security systems throughout the world, including gates, barricades, bollards and portable barriers. The company, run still by Dickinson and his son David, has more than 100 employees at its headquarters, where the equipment is manufactured. The bollards at Windsor Castle are made from carbon steel pipe and raised and lowered with a hydraulic pump,. The bollards come with decorative covers that can be painted to match the exterior of the building they protect. “Powder-coated safety black is used at Windsor Castle,” Hamm said. – Mark R. Madler
