Steel windows have a distinctive character that can completely transform the look and feel of a property. Their slender frames, generous glazing and architectural appearance make them a popular choice for both contemporary interiors and period homes. But once you’ve chosen your windows, selecting the right hardware is just as important.
The right fasteners and stays should complement the proportions of a steel window without overwhelming its clean lines. In this guide, we’ll explore the different types of hardware available for steel windows, the benefits of night-vent fasteners, how window stays work and the different styles and finishes you can choose from.

Why Choose Steel Windows?
Steel windows are instantly recognisable thanks to their narrow frames and strong, minimalist appearance. Unlike bulkier window materials, steel allows for slim sightlines while still providing the strength needed to support substantial panes of glass. This means more glazing and, in turn, more natural light entering your home.
Although steel windows are particularly well suited to modern, industrial and minimalist interiors, they are by no means a new design trend. Steel-framed windows became increasingly popular during the early 20th century and can still be found in many traditional and period properties today. Their enduring appeal comes from their ability to combine practical performance with a timeless architectural aesthetic.
They can also work particularly well as part of extensions, renovations and projects where you want to create a visual connection between indoor and outdoor spaces. Large areas of glazing help maximise views and daylight, while the slim metal frames provide a crisp, structured finish.
Because steel window frames tend to have much narrower profiles than traditional timber windows, the hardware needs to be carefully selected. Oversized handles or fittings can look out of proportion, whereas slimline hardware helps preserve the elegant appearance of the window.
What Hardware Do Steel Windows Need?
Once your steel windows are installed, you’ll need the right fittings to operate them comfortably and keep them securely in position. The two key pieces of hardware are window fasteners and window stays.
While both have a practical purpose, they also contribute significantly to the overall appearance of your windows. Choosing a design and finish that works alongside your existing door and window hardware can help create a more cohesive look throughout your home.
Night-Vent Fasteners
A window fastener is used to secure the window when closed and provides the mechanism needed to open it. For steel windows, a slimline design is particularly important because of the limited space available on the narrow frame.
From The Anvil's steel window fasteners have been specifically designed with an offset backplate to accommodate the slender profile of steel-framed windows. This helps the hardware sit neatly against the frame without compromising the clean appearance of the window.
The night-vent function is particularly useful in rooms where you want to introduce fresh air without fully opening the window. The fastener can be secured in both the fully closed position and the night-vent position, allowing ventilation while helping to maintain security.
Each fastener is supplied with a matching push plate keep and can be installed on either left- or right-handed windows. M5 machine screws are also included to provide a secure and straightforward installation.
Window Stays
While fasteners secure and operate the window, stays are responsible for holding it open. A traditional window stay consists of an arm, stay pin and stay rest, allowing you to position the window at different opening angles.
For steel-framed windows, a conventional stay can sometimes look too bulky for the narrow frame. From The Anvil's steel window stays have therefore been designed with a slim profile and offset backplate, making them well suited to the restricted space typically found on steel windows.
Each stay set includes a stay pin and stay rest, allowing the window to be held securely in a number of open positions. If additional security is required, a locking stay pin is also available separately. The locking pin incorporates a grub screw, helping to prevent the window from being opened further once secured.
There are two stay lengths available, 8” and 10”, making it possible to select an option that is appropriately proportioned for your window. As with the fasteners, M5 machine screws are included for installation.
How to Choose Hardware for Steel Windows
When choosing steel window hardware, it’s worth considering more than just the appearance of the fittings. The proportions of your window, the way it opens and the surrounding décor should all influence your decision.
Start by considering the size of your window and the available space on the frame. Slimline hardware with an offset backplate is generally the best choice for steel windows, as it provides the functionality you need without appearing too dominant.
You should also think about how the hardware will be used. If you regularly ventilate your home, a night-vent fastener can be a particularly practical choice. For windows that are opened frequently, adding a stay gives you greater control over how far the window opens and keeps it securely in position.
Finally, consider the finish. Matching your steel window hardware with your existing door handles, cabinet hardware or other architectural ironmongery can create a consistent look, while contrasting finishes can be used to make the windows a more noticeable design feature.
Steel Window Hardware Styles and Finishes
Good window hardware should feel like part of the overall design rather than an afterthought. From The Anvil offers several steel window designs, giving you the flexibility to choose something that suits both modern and traditional interiors.
Avon
With its clean, understated lines, the Avon collection is an excellent choice for contemporary interiors. It combines a streamlined silhouette with a refined finish and is available for steel windows in Aged Bronze, Black, Pewter Patina and Polished Brass.
Monkeytail
If you're looking to introduce a more traditional character, the Monkeytail design offers a decorative alternative. Its distinctive shape works particularly well in period properties and heritage-inspired interiors. Available finishes include Aged Bronze, Black, Pewter Patina and Polished Brass.
Newbury
The Newbury collection is a versatile option that balances traditional detailing with a timeless profile. The steel window range includes night-vent fasteners and stays, available in Aged Bronze, Matt Black, Pewter Patina and Polished Brass.
Reeded
For something with a little more texture, the Reeded design features distinctive detailing that adds visual interest to the otherwise simple steel frame. It is available in Aged Bronze, Matt Black, Pewter Patina and Polished Brass, making it easy to coordinate with a range of interior styles.

For an added layer of security, locking stay pins are also available in coordinating finishes. These can be paired with your chosen stays to create a practical and visually consistent solution.
Matching Steel Window Hardware to Your Interior
Steel windows often feature prominently within a room, so their hardware can have a surprisingly significant impact on the finished look. Fortunately, the range of available designs and finishes makes it easy to tailor the details to your interior.
For a contemporary scheme, Matt Black or Black hardware can reinforce the strong architectural lines of a steel frame. Polished Brass, meanwhile, can introduce warmth and contrast against darker frames, creating a more decorative finish.
Aged Bronze and Pewter Patina are particularly versatile choices. Their aged appearance works beautifully in traditional properties but can also add character to more modern spaces where you want to soften the industrial appearance of steel.
Rather than matching every piece of metalwork exactly, you can also use steel window hardware to complement other finishes throughout the room. Look at your door furniture, lighting, kitchen hardware and bathroom fittings when selecting your finish to create a considered overall scheme.
Complete Your Steel Windows with the Right Hardware
Steel windows offer a distinctive combination of strength, slim sightlines and timeless style, but the finishing details are what bring the design together. Choosing appropriately sized fasteners and stays ensures your windows remain easy to operate while preserving their elegant proportions.
Whether your preference is clean and contemporary, traditionally inspired or somewhere in between, there are plenty of options to choose from. From The Anvil's range of steel window hardware combines practical functionality with carefully considered designs, helping you create a finished look that complements your home.
