Door Control for Aluminium Partitions in Heavy Use Areas

On many occasions, we have had to respond to a design situation relating to the specification of architectural hardware on internal aluminium partition systems for commercial interior fit outs. Some popular standard 100mm suites do not accommodate a 60mm backset mortice lock due to the depth of the glazing pocket in the profile, limiting door furniture options to narrow-style furniture and mortice locks only. This in turn impacts the look and the cost, by resulting in variance of door furniture between base build and fit-out, or exterior doors and interior doors. Using commercial plate or round rose furniture on a 60mm backset mortice lock is more robust for heavy usage than narrow style mortice locks and narrow plate furniture.

In these heavy usage situations (particularly for education and health facilities), we need to consider aesthetic consistency, initial investment cost and ongoing maintenance cost. Stainless steel commercial round rose or plate furniture and 60mm backset mortice locks are the preferred option for exterior and interior doors across both the base build and fit-out.

In general terms, the initial investment cost differential between 100mm aluminium stile profile in conjunction with a narrow backset mortice lock and narrow style commercial plate furniture, and the 120mm or 125mm stile profiles and industry standard 60mm backset mortice lock and stainless steel commercial round rose or plate furniture, is neutral. We understand that specifying combinations of slightly wider stile profiles with standard furniture is more cost-effective when considering both initial investment and ongoing maintenance cost considerations, while ensuring the building tenant and owner a robust and long-lasting solution.
