From airports to embassies, from warehouses to depots, Delta crash-rated gates stop unauthorized pedestrians and vehicles from entering places that they don’t belong. Some models operate without contact with the ground across the opening, one is a manually operated swing gate and others operate with rack and pinion drives across V-groove wheel ground tracks while incorporating IR safety beam and safety edges. Swing versions are also available.

The clear openings range from 12 to 30 feet (3,657 mm to 9,144 mm). The standard height for all, except the swing gate, is 109 inches (2,769 mm). There are five different models to choose from, assuring that any facility can incorporate a gate that will definitively meet its security demands.

Not only can these popular crash gates withstand impacts as high as a 15,000 lb (66.7 kN) vehicle striking at 50 MPH (80 KPH) and suffer no significant damage, but they can look good too. Architects and contractors can choose from sliding and swing crash-tested gates in 14 different decors – green landscaping, screen printed glass, steel screen, back-painted glass, laser cut steel in two versions, panelized colored acrylic, panelized stone, panelized concrete, cast stone, wood and stone, panelized wood and wood screen.

Madoors's sliding security gates are powered by either electro-mechanical or hydraulic systems. Typical drive speeds are 60 ft (18.3 m) per minute, depending on electrical supply and gate length. Supplied madoors controls meet all requirements for control and safety.
