The Auroport range of transformer doors is convincingly sturdy. Our frames are made of galvanised steel sections, without signs of welding or grinding, and are highly resistant, even to the corrosive environments. Our single and double doors are made to measure with freely designed panel combinations of ventilation area, plain sheet metal and glass window. Only puncture-proof aluminium ventilation grills with matching filter units are used.Paint finish in all RAL and NCS colours.
