When it comes to choosing a bifold door manufacturer, there are many factors to consider. From the quality of materials used to the level of customer service provided, finding the right supplier can make all the difference in your business success. One company that stands out among bifold door manufacturers is TWR Group.

Who is TWR Group?

TWR Group is an industry-leading aluminium and uPVC fabricator based in the North East, UK. With over 23 years of experience in manufacturing high-quality doors and windows, they have established themselves as one of the most trusted names in the industry. One of the main reasons TWR Group has continued at the top for so long is the family side of the business, meaning customers get that personal connection with the company when they partner with them for their bifold doors.

How much experience does TWR Group have as a bifold door manufacturer?

TWR Group has been supplying installers across the UK since 2001, starting life as a PVCu fabricator before teaming up with leading systems company Smart Systems in 2012 and introducing aluminium bi-folding doors to its product offering, growing to the impressive figure of 100 doors per week in a matter of months. The TWR Group name has been synonymous with aluminium and bi-fold doors for the last 10 years, helping installers turn to aluminium due to increased demand from the domestic and commercial markets.

How are TWR Group’s bifold doors delivered?
