What Is A Mild Steel Slim Window Grill? Features of Our 6mm Grilles
Our slim window grill is a modern window grill made using 6mm solid mild steel bars. Compared to traditional window grilles which are around 12mm to 20mm thick, slim grilles provide a wider, less obstructed view.
The increased spacing also allows more natural light and ventilation into the home, creating a brighter and more comfortable living space. Despite their slim design, our mild steel bars are strong and durable, providing reliable safety and security for residential properties.
Why Homeowners Choose Slim Mild Steel Window Grilles
1. Maximum Outdoor View: Slim 6mm bars create minimal visual obstruction, allowing more light and a clearer view outside.
2. Strong & Hard to Bend or Cut: Made from solid mild steel bars, our slim grilles are very strong and offer excellent resistance against bending or cutting.
3. Anti-Burglary Security: Strong mild steel construction provides reliable protection and is one of the best choices for home security.
4. Simple Modern Design: Clean, modern designs that are fully customizable to suit your home.
5. Quality Workmanship: Fabricated and welded by experienced technicians to ensure strength, durability and a neat finish.
6. Long-Lasting Protection: Powder coated for excellent corrosion resistance and durability in Singapore's hot and humid climate.
Types of Slim Window Grill
We offer a range of slim window grill types to suit different homeowner needs and property requirements, including sliding grilles, swing open grilles and fixed grilles.
1. Sliding Window Grilles
Sliding window grilles are one of the most popular choices for HDB flats and condominiums. They are practical, space-saving and do not interfere with curtains or blinds when opened, making them suitable for bedrooms and living rooms.
2. Swing Open Window Grilles
Swing open window grilles can be opened fully to provide a clearer and less obstructed view. They are also convenient for cleaning both the grille and window glass.
3. Fixed Window Grilles
Fixed window grilles are ideal for homeowners who prefer a clean and minimalist look. Due to their slim profile, the grill sits closer to the wall for a more flush and less bulky appearance, which helps the room feel more spacious. This is especially useful for HDB flats and smaller rooms.
Window Grill Designs & Colours
Modern window grill designs focus on clean lines, minimal obstruction and better airflow, while still meeting HDB and condominium design guidelines. Many homeowners prefer simple horizontal slim bar designs for a wider view, while others may choose vertical or square patterns depending on their home style and preferences.
Our grilles are also available in white, black, light grey, brown and other colours to match or complement your window frames. Choosing the right colour can help the grilles blend seamlessly with the window design or create a subtle contrast to enhance the overall look of the space.
Spacing Gap Between Grill Bars
The gap spacing between grill bars can be customised.
4 to 4.5 inch is the normal bar spacing (measured between each bars) for our window grilles. However the spacing can be customised to suit your needs. It can range from as narrow as 1.5 to 2 inches to as wide as 5 to 6 inches.
5 to 6 inch spacing:
This wider gap spacing is ideal for homeowners who want the least grill bars blocking their window. With wide bar spacing and less grill bars, you can get to enjoy clearer and more open window view.
1.5 to 2 inch spacing:
This narrower spacing is popular with owners who have small pets at home, as it helps prevent the pets from slipping through the gaps and improves safety.

How Much Does a Slim Window Grill Protrude?
We usually try to install the window grill as far inwards as possible, as long as there is enough space on the window ledge. This helps to reduce how much the outer frame protrudes out.
When we install the windows and grilles together, the grill can usually be positioned further inwards because the window can be shifted further outwards. As a result, the grill will often be flush with the wall or have only minimal protrusion.
However, there must still be enough space between the window and the grill. For example, casement window handles must remain easily accessible and should not be blocked by the grill.
For grill installation without replacing the existing windows, below is a general estimation of how much the outer frame may protrude:
- Sliding Grill: up to around 2 to 2.5 inches
- Swing Open Grill: up to around 1.25 to 1.5 inches
- Fixed Grill: usually flush with the wall or with very minimal protrusion due to its slim outer frame
If the windows and grilles are installed together, sliding, swing open and fixed grilles can usually all be installed flush with the wall or with minimal protrusion, subject to site conditions.
Where Window Grilles Are Commonly Installed in Singapore Homes
In many BTO flats, the living room and bedroom windows usually consist of 3 sections. The top section is top hung panels, the centre section is casement or sliding windows, and the bottom section is fixed panels. In such layouts, window grilles are commonly installed on the centre section only, or on both the centre and top sections.
In some older HDB flats, the windows usually consist of 2 sections. The top section is top hung panels, while the bottom section is casement or sliding windows. In these cases, window grilles are commonly installed on the bottom section only, or on both the bottom and top sections.

What to Expect When Buying & Installing Window Grilles from Pang Giap
1. Custom-Made to Fit Your Windows
Every home layout in Singapore is unique. No matter if you are living in an HDB flat, BTO unit, condo, or landed property, our team provides precise on-site measurements to make sure your slim grilles fit perfectly to match your windows.
We design every grill carefully, making sure the grill bars do not block your day-to-day access to window locks and handles. Finally, we handle the installation with care to ensure the grilles fit securely, followed by thorough testing to make sure the opening mechanism and locks are working smoothly and safely.
2. Maximized Natural Light and Outdoor Views
Unlike traditional grilles with thicker bars that can make a room feel enclosed like a cage, our slim 6mm bars with customized spacing allow for a much wider view of the outside.
This minimalist profile allows more natural light into your home, making your rooms appear brighter, bigger, airier and more welcoming.
3. Easy to Clean and Maintain
Our slim window grilles are available in sliding, swing open and fixed designs. Sliding and swing open grilles provide easier access to the windows, making it more convenient to clean both the grilles and window glass.
The simple design of slim grilles also makes them easier to maintain. Cleaning is easy as the grill bars are thin, so a simple wipe with a damp cloth once in a while is all it takes. Plus, our mild steel grilles are powder-coated for added durability and protection.
