IS ALUMINIUM A SUITABLE ALTERNATIVE FOR THE REPLACEMENT OF STEEL PRODUCTS? - BUYERS GUIDE

The first steel windows were manufactured by Francis Henry Crittall, who took over the Braintree based CRITTALL® window business from his brother in 1884. The distinctive steel windows were hugely popular after the First World War when there was a demand for quality, durable windows.

One of the major problems with using steel as the framework for windows and doors can be the prohibitive cost. Compared to using aluminium as the framework, other potential hurdles to overcome when considering steel are thermal compliance to current Building Regulations and very long lead times.

Benefits of Aluminium	Comparable Qualities of Aluminium
Cost - Aluminium windows and doors are a fraction of the cost of steel making them a viable alternative to costly Steel.

Accepted by many local authority planning and conservation officers where a like for like steel replacement is required.
Aluminium requires little to no maintenance and does not rust like steel	Can accommodate an array of matching hardware options such as Art-Deco or other vintage handles.
Lead times for Aluminium are typically shorter than for Steel	Suitable for period Victorian, heritage, Georgian, Art-Deco projects.
Modern highly secure locking systems including PAS 24 to single and double doors that are more secure than Steel	Used externally as garden, courtyard or balcony French doors with or without side light window panels.
