Collapsible metal doors with a horizontal rotation axle, specially designed for exits of emergency pedestrian staircases from undergrounds, such as the Tube, railways, tunnels, basements, etc. Under emergency evacuation conditions, they are fully operational without power supply, by means of mechanical drive exclusively.<\/p>\n

Manufacturing dimensions are fully adjustable to project needs.<\/p>\n

In its closed position, it is completed levelled to the floor. It looks discreet and integrated.<\/p>\n

To open it, the mechanism runs without the need of power supply; the mechanical lock is released manually, which enables the door to reach its open position immediately through a proper counterweight and without any efforts or interventions.<\/p>\n

The opening handle can be fitted in the most convenient position to be operated upon evacuating, because it connects a threaded steel cable with the mechanical lock.<\/p>\n

The opening is soft thanks to a hydraulic damper that accompanies the movement, especially at the beginning and end of its opening and closing runs.<\/p>\n<\/div><\/div><\/div>

For closing, the process is manual and reversed, with minimum effort, as the door is in counterweighted balance.<\/strong><\/p>\n

All moving elements are protected by metallic coatings, thus avoiding accidents due to trapping or crushing (counterweights, pulleys, cables, etc.).<\/strong><\/p>\n

The external frame is dimensioned to be fitted in its place and also to support side rotation points, which are removable for mandatory regular maintenance.<\/strong><\/p>\n

It can optionally be equipped with an emergency opening that can be open from the outside.<\/strong><\/p>\n

The door leaf can be manufactured in steel, stainless steel, laminated sheet metal in steel or aluminium, galvanised sheet metal or Corten.<\/strong>
\nFinishes can be: galvanised, lacquered, polished and varnished.<\/strong><\/p>\n<\/div><\/div><\/div>

TRAP DOORS OPERATED BY GAS SPRINGS<\/strong><\/span><\/h2>\n<\/div>

We also have manually-operated trap doors compensated by gas springs.<\/p>\n

This is a tailor-made product that can address almost any need. We can manufacture small, light trap doors to access a hidden mechanism or trap doors that also have to withstand traffic of extremely heavy vehicles on them.<\/p>\n

In any case, they can be balanced by means of gas springs, which makes it possible to open them almost 90\u00ba, a limited opening speed and manual operation with little effort and without the need of being motorised or having counterweights installed.<\/p>\n

Manufacturing dimensions are fully adjustable to project needs, although restrictions set by available gas springs limit their dimensions to about 2 metres by side.<\/p>\n

In their closed position, they may be fully levelled to the floor. They look discreet and integrated.<\/p>\n

They are delivered assembled and finished, with the type of anchoring necessary as requested for their installation.<\/p>\n

The door leaf can be manufactured in steel, stainless steel, laminated sheet metal in steel or aluminium, galvanised sheet metal or Corten.<\/p>\n

Finishes can be: galvanised, lacquered, polished and varnished.<\/p>\n

The estimated life of gas springs is over 30 years. Their cycle of usage is tens of thousands of complete operations and continuous use. Furthermore, they do not need any maintenance.<\/p>\n
