Choosing an HDB gate isn’t just about finding the cheapest quote. A gate may cost less on a catalogue page but become more expensive once you add measurement, installation, dismantling, disposal, locks, design upgrades or GST.
According to published Singapore supplier pricing for 2026, basic HDB gates can start at $450, while laser-cut, highly customised aluminium gates can go up to $1,500 – $2,000, depending on materials and specifications. These are market reference ranges, not fixed prices, because suppliers do not always include the same items in their advertised figures.
In this article, we compare the different HDB gate suppliers in Singapore. This comparison does not assume that one type of gate is definitely better for any HDB home. It compares pricing, materials, and product lines, as well as factors to consider before paying a deposit.
Best HDB Gates Suppliers in Singapore
Here are the best HDB gates suppliers in Singapore. Choose one that suits your needs.
1. Gate Door Window (GDW)
GDW provides HDB gates in mild steel, wrought iron, aluminium and other types of designs, such as standard, slim, stencil, laser-cutting and pet-friendly gates. There are 3 × 7ft and 4 × 7ft sizes available in GDW’s collection.
In terms of cost, the GDW’s HDB Gates page presents an initial rough estimate from about $300 to $900+ for HDB Main Gates. In addition, GDW’s metal gates page lists S720 to S1,160+ for selected mild steel gates.
GDW also provides measurement and installation services. GDW’s published warranty period is 10 years for gates, doors, and windows, and 3 years for digital locks. An added benefit is that homeowners can arrange a set consisting of a main door, digital lock, and gate at the same time.
- Best suited to: homeowners in search of a combined gate, door and lock solution.
- Best for: HDB-focused gate, door and digital-lock packages
2. AT Aluminium
Best for: Aluminium gates and modern designs
AT Aluminium is the second supplier in this comparison. Its current 2026 guide gives these indicative prices:
- Mild steel HDB gates: $450-$900
- Aluminium HDB gates: $700-$1500
- Custom laser-cut aluminium: $1200-$2000
ATA provides aluminium and metallic gates, including HDB metallic and mild steel gates. The website also states that their gates, doors, and windows come with a 10-year warranty, and the company is an HDB Licensed Renovation Contractor.
Consider aluminium if you want a lightweight gate with excellent anti-corrosive qualities. Customised aluminium gates will be relatively more expensive than the standard steel gate.
Best suited to: homeowners who prioritise aluminium, modern styling or lower maintenance.
3. HDDoor
HDDoor offers many metal gate models for HDB and BTO, making it useful for people who want to compare individual designs. One mild steel metal gate design, known as the HD-501, is priced at around $750-$950 for 3 x 7 ft and 4 x 7 ft models.
Other designs vary in price based on their specific features. Additional options, like laser-cut numbers and extra panels, can increase the total price. HDDoor offers premium installation for listed products, and their gates come with a 12-month warranty.
- Best suited to: buyers who want a wide catalogue and model-level price comparisons.
- Best for: Large catalogue and published model prices
4. MAGworks
MAGworks offers gates made of mild steel and aluminium and publishes prices for each of its HDB gate models. Currently the SH003 mild steel HDB gate costs $488. The published package includes: gate itself, unit number, handle lock set, measurement, delivery, installation, dismantling, and disposal.
Other MAGworks models cost different amounts, and $488 is an example only, not a universal price. Therefore, this source may help you compare less expensive packages with others.
- Best suited to: homeowners looking for a straightforward HDB gate package.
- Best for: Budget-conscious buyers
5. Laminate Door
Metal-Gate at Laminate Door comes with a special catalogue that comprises several HDB mild steel gates that are currently in fashion. Published examples generally fall around $700 – $1100.
For example, its LD-608 mild steel gate costs $750 to $950 for 3 x 7 ft and 4 x 7 ft.

- Best for: Mild-steel catalogue designs
6. Prefab Technology 3
Technology 3 manufactures metal products such as wrought iron gates, mild steel gates, and 3D laser gates. The manufacturer’s product description indicates that it offers customised sizes and profiles and that its products are approved for use under the HDB Material Listing.
Unlike some online catalogue suppliers, it does not give a straightforward price list of HDB gates for online catalogues like some other companies. For this reason, homeowners should treat it as a quotation-based option and provide the same size and design requirements used when comparing other suppliers.
- Best suited to: homeowners interested in metal fabrication and customised gate options.
- Best for: Metal fabrication and customised options
How Much Does an HDB Gate Cost in Singapore?
An approximate budget for an HDB gate in 2026 is roughly $450 to $ 1,600, or more.
Published supplier information gives a useful picture of the current market:
| Gate type | Indicative 2026 price range |
| Basic mild steel | $450 – $900+ |
| Wrought iron | Around $600 – $1400+ |
| Aluminium | $700 – $1500+ |
| Custom laser-cut aluminium | $1200 – $2000 |
| Premium/custom designs | S$1,500+ |
The above prices should not be treated as a universal Singapore price list. For instance, ATA currently indicates that mild steel HDB gates go for about $450 – $900, aluminium for about $700 – $1,500, and laser-cut aluminium for about $1,200 – $2,000.
Meanwhile, GDW offers a wide range of main gates from $300 – $900+, but according to GDW’s prices for HDB metal gates, mild steel HDB gates may cost between $720 and $1,160+.
Before comparing quotations, ask whether the price includes:
- Site measurement
- Gate fabrication
- Surface finish or powder coating
- Hinges and hardware
- Lockset
- Dismantling of the existing gate
- Disposal
- Delivery
- Installation
- GST
A $500 gate and a $750 gate may therefore represent completely different packages.
What Changes the Price of an HDB Gate?
Several details can move a gate quotation significantly.
Gate size
Commonly available dimensions are 3 × 7 ft and 4 × 7 ft gates. For example, GDW offers both options from their HDB gate catalogue. However, a homeowner should not order strictly based on the standard dimensions offered on the website. Measure the existing gap before fabrication.
Material
Mild steel, wrought iron, aluminium, and stainless steel have different costs and fabrication requirements.
Design
A simple vertical bar gate is typically easier to fabricate than a gate with many cuts, laminations, or decorations.
Lock and hardware
Traditional locks are included in the basic package, while digital locks or special lock backs can increase the total cost.
Installation and removal
Some suppliers include installation and dismantling in the package, while others provide separate quotations for each component.
Finish
Since a steel gate is exposed to Singapore weather, it is important to understand the finishing process rather than compare designs alone.
How Much Does It Cost to Change an HDB Gate?
Replacing an HDB gate may fall under the same general market category as buying a new one. The approximate 2026 budget for the replacement of a typical gate may be somewhere between $450 – $1,600+, based on the material, size, design and lock. But make sure that the quote covers the dismantling of your current gate. Quote for:
Gate + measurement + installation + dismantling + disposal + lock + GST
It becomes much easier to compare suppliers this way. If you need to replace your main door and gate at the same time, check whether the company offers a package service.
How Do I Know if My Contractor Is HDB Approved?
It is important to distinguish between an HDB-approved product and an HDB-registered renovation contractor.
When renovating an HDB flat, HDB recommends that homeowners use contractors listed in the Directory of Renovation Contractors (DRC).
Before signing the quotation, verify:
- Name of the company.
- Company in the HDB DRC.
- The quotation in the same company’s name.
- Scope of works included in the quotation.
- Applicability of renovation approval/permit, if any, for the specific work.
Do not rely only on a supplier’s statement for “HDB Approved.” Verify this information from the HDB directory yourself.
How Do I Replace an HDB Gate in Singapore?
A straightforward replacement process looks like this:
1. Measure the existing opening
Do not rely only on catalogue dimensions.
2. Choose the material
Decide between mild steel, aluminium, wrought iron or another suitable option.
3. Select the design
Simple gates are generally cheaper than customised or laser-cut designs.
4. Decide on the lock
Tell the supplier if you want a digital lock before fabrication.
5. Compare quotations
Get at least three quotations and make sure they use the same basic specifications.
6. Check what is included
Confirm measurement, installation, dismantling, disposal, GST and warranty.
7. Verify the contractor
Check the company through HDB’s Directory of Renovation Contractors where applicable.
8. Confirm the final measurement
Only proceed with fabrication after the supplier confirms the actual opening and specifications.
Final Tips Before Buying an HDB Gate
Before confirming your order, make sure the quotation clearly states:
- Gate size
- Material
- Design
- Finish
- Lock
- Installation
- Dismantling
- Disposal
- GST
- Warranty
A quotation for a $488 mild steel package should not be equated to the $900 quotation for a different material, design, lock and warranty. The best HDB gate may not be the least expensive gate. Instead, it should fit the dimensions of your current gate, meet the necessary specifications, and complement your home aesthetically.

Frequently Asked Questions (FAQs)
How much does a new HDB gate cost?
For a standard-size (typically 3 ft × 7 ft) HDB gate in Singapore, prices generally range from about S$450 to S$1,600+. Basic mild-steel gates start from around S$450–S$550, while aluminium, wrought iron, stainless steel, or custom designs (laser-cut, privacy panels, louvres, etc.) cost more. Final pricing depends on material, design complexity, size, finish, lock type, and whether removal of the old gate and installation are included. Always request itemised quotes.
How much is the cheapest HDB gate?
Basic mild-steel HDB gates can start from around S$450–S$550 (supply and install) for standard designs. Some suppliers list simple models near this range. These entry-level options are usually simple grille-style designs with powder coating and a standard mechanical lock. Confirm exactly what is included before buying.
Which type of gate is the cheapest?
Mild steel is generally the most affordable option for HDB gates. It offers good strength and design flexibility at a lower price than aluminium or stainless steel. Wrought iron and stainless steel typically cost more, while aluminium sits in a mid-to-higher range depending on the design.
Can I change the HDB main gate?
Yes. You do not need an HDB renovation permit to replace the main HDB gate, provided that the new gate meets HDB guidelines. Key requirements include:
- The dimensions, panels, and opening-swing direction of the new gate should be the same as the previous gate.
- There should be enough clearance so the gate does not block corridors or fire escape routes.
- The unit number remains clearly visible.
- A DRC-listed contractor carries out work.
What is the best material for an HDB gate?
There is no single “best” material, as it depends on your requirements:
- Mild steel: Most popular and practical choice. Affordable, strong, and highly customisable. Needs occasional inspection of the coating.
- Aluminium: Excellent for low maintenance and rust resistance. Lightweight and ideal in humid climates, but generally less impact-resistant than steel.
- Stainless steel: Very durable, resists rust and requires minimal maintenance, but more expensive and often more limited in intricate designs.
- Wrought iron: Strong and decorative, with good coating options, but heavier and usually higher cost.
For most HDB homeowners, mild steel offers the best balance of price, strength, and design options.
Which gate is better, aluminium or iron?
Aluminium is lighter, naturally rust-resistant, and requires very little maintenance—making it convenient in Singapore’s humid climate. Wrought iron or mild steel is generally stronger and comes in different designs (especially intricate or heavy-duty styles), but needs proper powder coating (and occasional touch-ups) to prevent rust.
Choose aluminium if low maintenance and rust resistance are your top priorities. Choose mild steel or wrought iron if you prioritise strength, security, and design variety at a more competitive price. Compare full specifications, thickness, coating quality, and warranties rather than material alone.
