MAIN FRAME – all welded, made of metal profiles of complex construction. Painted with electrostatic paint. Is fixed to the primary frame with 8 screws through floating inserts.
STEEL PANEL – constructed with the aim of providing a higher degree of protection, is made from entire steel leaf with stiffening ribs along the perimeter.
INNER PANEL – inner steel panel consists of two special steel frames for improving door stiffness.
SAFETY FRAME – is settled on the steel panel for additional safety of lock system.
INSULATION – between the two steel panels there is insulation material penopolisterol that guarantees a high degree of insulation (48dB) from heat and sound. Certified.
LOCK – ESTA doors are equipped with CISA lock system. We offer several types of lock systems according to the model of the door.
MANGANESE STEEL PLATE – they are used on all ESTA doors for better security and prevent drilling-out of locks.

STEEL LOCKING RODS – fixed on the steel panel at the side of hinges, 5 steel locking rods enter corresponding holes in the door frame and resist the attempts of lifting the door panel.
STEEL HINGES – with adjustment possibilities on a three dimensional plane to provide equal distribution of load.
DECORATIVE FACING PANEL – produced from the excellent veneering material.
ALUMINIUM PROFILE – provides secure fixing of decorative panels and protects them from mechanical damage along the perimeter.
FURNITURE – ESTA uses special furniture for steel doors.
FIXED DOORSTEP – installed on the lower part of the door it gives additional stiffness to the main frame and covers the void.
STEEL LIGHT – entrance door with glass.
