What makes brass so good?
Still Australian designed and made, the Lockwood range has adapted as design trends have come and gone but one thing has remained constant - the high quality brass used to make it. Whether it is for aesthetics, ergonomics, functionality or durability brass remains the ideal material for high quality door furniture.

Brass is highly durable
Brass has a low friction surface which makes it ideal for connected moving parts. This is why it is the perfect choice for producing high use door furniture that will prove durable with minimal servicing. Lockwood brass door furniture has been successfully tested to exceed the highest durability rating (D8, 500,000 cycles) under the Australian Standard (AS4145.2: 2008).

Brass is corrosion resistant
Brass door furniture provides durable performance in high corrosion applications. Unlike other commonly used materials it contains no iron so it will not rust or tea stain in high corrosion environments. Lockwood Brass Door Furniture in satin chrome brushed finish (SC) has been successfully tested under NATA conditions to maintain both function and finish under prolonged neutral salt spray test for over 1000 hours satisfying the highest ranking (C10) of the appropriate Australian Standard (AS4145.2: 2008). This result confirms that Lockwood Brass Door Furniture the ideal choice for use in coastal applications and other corrosive environments.

Brass is green
Brass is a highly machinable material making it able to be accurately manufactured with less scrap, less rework and less energy than other materials. Products made from brass generally have good "cradle-to-grave" characteristics as not only do they show good durability but brass is also readily recycled at the end of the products working life. Furthermore Lockwood Brass Door Furniture is manufactured right here in Australia so there is far less energy expended shipping product into the country and the manufacture occurs at ASSA ABLOY Australia's ISO 14001 accredited manufacturing facility.
