Bronze Doors - Formed Bronze Balanced Doors
More about this product
Ellison formed stainless steel balanced doors can be constructed to suit an architect’s design concept. The shaft containing the torsion bar closer spring can be either concealed within the formed stainless steel frame, or exposed. These doors can also be equipped with Ellison PowerNow power operators.
Ellison's revolutionary PowerNow design
An Ellison PowerNow-equipped balanced door features a low energy operator, concealed in the frame header, and an actuating arm that provides the opening force on demand. Ellison’s standard hardware provides the closing force.
When power is not needed during manual operation, Ellison PowerNow-equipped balanced doors operate the same way as standard Ellison balanced doors – the power operator is never engaged, reducing operator wear and maintaining Ellison’s signature manual ease of operation.
Any Ellison balanced door can be specified as PowerNow-equipped. Power operators are available in your choice of two leading manufacturer’s – Stanley and Horton.
USES AND APPLICATIONS
- Public Entrances
Life Cycle:The average lifespan of a typical high-traffic commercial entry door is about 10 years. For an Ellison custom balanced door, the expected lifespan is 80 years and counting. Many of the earliest Ellison balanced doors (from the 1930's) remain in operation to this day. This means, in time, at least seven doors would have to be manufactured in order to serve the duration of just one Ellison custom balanced door.
Materials: Ellison custom balanced doors (excluding wood doors) are comprised almost entirely of metal and glass, two of the world's most readily recyclable and upcyclable materials. In fact, only two very small – but critical – components are polymer based, to ensure long term corrosion resistance. What's more, most Ellison doors are made from particularly valuable metals like bronze and stainless, which helps to ensure their eventual recycling.
Manufacturing: Ellison produces nearly the entire balanced door in-house. For example, all balanced hardware is cast in Ellison's foundry and tooled in Ellison's factory. Virtually no material is wasted, as unused material is remelted for reuse. Also, under a sustainable manufacturing program sponsored by the New York State, Ellison has also implemented manufacturing systems that maximize both water and energy conservation.
