Not sure which product is right for your project, or want to know more about how we work? Here are the answers to the questions we get asked most often.
Yes. We run free weekly delivery routes covering Birmingham and the wider West Midlands from our hub near Stafford. There is no minimum order value, and our drivers deliver direct to site on the day agreed at point of order.
Yes, in particular the steel-look Steellook range from AWG has been designed specifically for period and heritage properties, replicating the slim sightlines and traditional proportions of original steel windows. It is an ideal choice for conservation area projects, listed buildings and any property where a sympathetic, heritage-appropriate window is required.
Our aluminium windows can be powder coated in virtually any RAL colour, giving you an almost unlimited choice of finishes. Dual colour options are also available, allowing the inside and outside of the window to be finished in different colours. This makes aluminium windows an extremely versatile choice for both contemporary and traditional projects.
Yes. All our modern aluminium windows use advanced thermal break technology and double glazing as standard to reduce heat loss and energy bills. Our Alitherm 400 range is WER A+ rated and fully compliant with Part L.
We work primarily with trade customers including installers, builders and developers. Opening a trade account gives you access to trade pricing, a dedicated contact and 24-hour quote turnaround. Contact our friendly team to get set up.
We supply aluminium frames in a wide range of colours, including standard stock colours like anthracite grey, black and white, plus the full RAL colour palette and dual-colour options where the interior and exterior finish differ.
Aluminium windows offer slimmer frames, greater structural integrity and excellent thermal performance compared to uPVC windows. The slimmer profiles let in more natural light, while powder-coated finishes need only an occasional wipe to stay in top condition. They typically last 40+ years, making them a smart choice for installers.
Birmingham installers and builders work to tight schedule, and a late delivery or a slow quote can hold up an entire job. Midland Aluminium takes that pressure off. We supply trade aluminium windows across Birmingham and the West Midlands with 24-hour quote turnaround, lead times from 2-3 weeks on stock colours, and free delivery direct to site on our weekly regional routes.
Our team knows the Smart Systems range inside out, holds substantial stock at our Stafford hub, and manufactures 1,500+ frames a week through the Affordable Windows Group. Speak to our team today to get aluminium windows for your next job.
Every aluminium window we supply is built with advanced thermal break technology and double glazing as standard, reducing heat loss, lowering energy bills and meeting the requirements of Part L.

No two projects are the same, which is why we supply the full Smart Systems aluminium window range. Alitherm 400 casement windows suit new build and replacement work with slim sightlines and PAS24 security. Flush sash aluminium windows give a clean, contemporary finish complete with our concealed hood vent.
For period properties and conservation areas, our Steel-Look heritage aluminium windows recreate traditional steel profiles with modern thermal performance. We also supply matching aluminium doors, bifolds and sliding patio doors, so you can specify the full project from one trade supplier.
