Features/Applications:
• The STB series of sheet steel enclosures are designed to meet the
requirement for distribution and lighting junction boxes.
• Available in 14 sizes with standard finishes of painted or 316L
stainless steel, together with the high IP rating, make these
enclosures suitable for all environmental conditions.
• The stainless steel versions are particularly recommended for use
in marine or other corrosive environments.
• Painting of these enclosures uses a two stage elecrophoretic dip
coat system.
• Treatment includes iron phosphate and paint application followed
by electrostatic polyester powder coating.
• When applied to a mild steel substrate gives a minimum of 500
hours salt spray resistance.
