We produce quality steel window solutions for awnings, French casement and fixed windows. As well as our standard black steel windows, we also offer a number of custom paint options to create a distinctive look and feel. We guarantee our work for every project and each Portella window carries an exceptional warranty that goes way beyond the industry standard to protect the longevity of your investment.
With narrow sightlines and custom shapes, our window configurations can fit virtually any application to meet the demands of discerning homeowners and businesses alike. Creating custom size steel windows allows us to work directly with builders and architects and meet the exact specifications of their projects. Most importantly, our state-of-the-art manufacturing processes and factory glazing allows us to keep every process in-house. That eliminates subcontracting and mark-ups so we can deliver the finest quality steel windows at the best possible price.
We currently manufacture four categories of steel windows, each of which features a number of unique designs. Our product lines include:
- Thermally broken – Our thermally broken windows exceed all energy efficiency requirements. We are the only steel window manufacturer to include a thermally-bonded zinc galvanizing corrosion resistant coating. That ensures your new windows last a lifetime even in the harshest climatic conditions.
- Classic – The classic range of custom steel windows is the perfect complement to contemporary architecture, featuring slender lines and minimalist profiles that let light flood into your home.
- Storefront exterior – Create a striking storefront with steel windows that stop customers in their tracks. The superior strength and durability of rolled steel makes it ideally suited to demanding commercial environments and boutique stores. Interested? Take a look at our luxury Double Casement Windows.

Whatever you choose, each of our custom metal windows has its own characteristics to create a distinctive look and feel, from modern and minimalist to historic and traditional. They also boast superior climate durability to withstand the most demanding conditions.
