Commercial steel windows, screens and doors can be specified using a number of rolled steel window profile suites. W20 and W40 are the most common systems nowadays and these can be used to manufacture a range of window/door styles. Specifications vary between jobs but we can supply single glazed steel systems through to 26 mm double glazed systems.
Please take a look at the drop down menu above which gives more detail on W20 and W40 profiles.
