6 Best Mild Steel Gate Suppliers in Singapore (2026): Prices, Ratings & What They Actually Deliver

Buying an HDB gate often starts with the same thing: a catalogue photo and a “from $499” price. The problem is that neither tells you much about what you’re actually buying. The photos were well edited, so you were convinced to order without further investigation.

The gate arrives. It looks like the photo. 

Eighteen months later, you see rust appear in the corners of the gate. It has gotten orange. The paint has gone chalky where the afternoon sun hits the corridor, and the digital lock doesn’t work.

One of the things that most people don’t pay attention to is that such details do not show up in the catalogue. Catalogues are for sales. It shows up in the specification, and the specification is the part nobody publishes. 

This guide is your way out. It covers the top 6 suppliers that genuinely fabricate mild steel gates for Singapore homes, rather than door showrooms carrying a gate SKU to round out a bundle. 

For easier decision-making, I have covered what 2026 prices actually contain once measurement, disposal, locksets and GST are counted, and how to read a Google rating that says 4.9. 

How This Shortlist Was Built?

Gates are essential to any Singaporean home. Here are the five filters I applied before adding anyone in the ranking.

Fabricates mild steel for the Singapore market. Through thorough research, I added workshops and factory-direct suppliers, not resellers drop-shipping a catalogue.

A checkable public price or catalogue band. If nothing is published anywhere, the supplier cannot be compared, only visited.

Verifiable HDB renovation or BCA contractor standing — or an explicit statement that they do not take HDB work.

Enough public reviews to show a pattern. Volume beats score. A 5.0 built on a single review carries less information than a 4.2 built on 337.

Steel thickness or coating method stated somewhere, or available on request.

Why were some disqualified? We eliminated door-only showrooms, aluminium specialists filed under “gate supplier”, and outdated directory pages carried forward from 2025 with the year swapped in the title. 

What A Mild Steel Gate In Singapore Actually Is

Mild steel is made from low-carbon steel —an alloy made primarily of iron with a carbon content typically between 0.15% and 0.25%. Since it is low-carbon steel, it cuts, bends and welds easily. This low carbon content is the key to everything: it makes the material easy to weld and simpler to form into any shape without cracking. 

Which is why it dominates HDB corridors and why laser-cut panels cost what they cost. 

In practical terms, this means that you can bend mild steel into modern geometric patterns, traditional grille designs, or custom laser-cut motifs — all with the same base material. 

And the best part is that its solid structural integrity helps it withstand daily impacts without any major damage.

If a quotation does not state bar thickness and coating method, assume the cheaper imported gauge and a single-layer spray. Suppliers who use the good stuff will put it in writing, because it is what justifies their price.

The Top 6 Mild Steel Gate Suppliers in Singapore: Things Most Singaporeans Forget to Check

1. AT Aluminium

AT Aluminium stands out for the amount of information it puts around a relatively straightforward product. Its Google profile shows 4.8 stars from 817 reviews, while its own listings give buyers actual prices to work from. That makes it easier to investigate the quote before committing. 

AT Aluminium prides itself on offering stylish, durable, and low-maintenance products that stand the test of time. They offer a wide range of aesthetically pleasing, high-strength aluminium products to meet your needs. Crafted from premium-grade mild steel, our gates are designed for outstanding strength, durability, and rust resistance. Featuring a high-quality powder-coated finish, we prioritise using superior materials to deliver a product built to last.

Standard mild steel gates cost around $800-$1,500, custom designs around $1,500–$3,000, and automated gates $2,500 and above. The promotions page lists a 3 × 7 ft mild steel gate at $780 with a ten-year warranty attached.

Best for: Buyers who want the gauge, coating and lock specification written down before fabrication, and who will trade a low headline price for a warranty that outlasts the paint. Poor fit: anyone shopping purely on the cheapest 3 × 7 net figure.

2. HDDoor

HDDoor is a direct manufacturer and supplier and states that it has factories in Singapore. That is the company’s own positioning; buyers who specifically want factory-direct fabrication should still ask where their chosen model is manufactured and what fabrication and coating specifications are included in the quotation.

HDDoor is one of the top suppliers on this list to price from its own catalogue because it publishes individual mild steel gate models online rather than hiding them behind a quotation form. Its HD-513 is currently listed at S$750–S$850 for 3 × 7 ft and 4 × 7 ft sizes. Other models move higher: HD-510 is S$850–S$1,050, while the HD-561 is listed at S$1,150–S$1,250.

For example, the HD-510 offers a laser-cut panel for an additional S$100, while the HD-501 lists a S$100 laser-cut unit number and a S$50 bottom panel as optional additions.

Best for: Buyers who want a large catalogue with published model-level pricing and optional design upgrades.

3. Laminate Door

Laminate Door is one of the more transparent suppliers on this shortlist when it comes to model-level pricing. Its catalogue currently puts the LD-621 and LD-625 at S$850–S$1,050, while more elaborate designs move higher: the LD-628 is S$950–S$1,150, the LD-638 laminate-design gate reaches S$1,500, and the LD-642 privacy gate is listed at S$1,180–S$1,380.

That pricing spread is more useful than a single “from” price. It shows that with Laminate Door, the design category itself can materially change the budget. The LD-650 laminate mesh gate, for example, is listed at S$1,050–S$1,150 for 3 × 7 ft or 4 × 7 ft, with the supplier stating that delivery and installation are included.

The supplier also describes itself as a direct factory supplier, so if fabrication quality is part of your buying decision, ask for the actual steel specification and coating process rather than treating the “direct factory” label as proof of either.

Best for: Buyers who want a wide design range with model-level prices published upfront, particularly laminate, privacy and mesh-style gates.

4. Ho Ho Engineering and Renovation Works

Ho Ho is the most technically transparent fabricator on this shortlist. Its published material gives buyers something many gate catalogues do not: a measurable steel thickness and a stated finishing method. The company uses high-quality mild steel at 1.6 mm thickness that provides better strength. The gates finish is powder coating rather than spray painting. It also publishes specific colour references, including PR12/708 matt black and RAL 7042 traffic grey, rather than simply showing a colour swatch labelled “black”.

That level of specification makes the published starting prices easier to interrogate. Ho Ho lists gates from S$499 for 3 × 7 ft, with larger 3 × 8 ft and 4 × 7 ft configurations starting from S$599. It also offers bundled pricing, including a gate-and-main-door package from S$1,098. The key point isn’t that the gates are inexpensive; it is that the catalogue gives you enough information to ask what construction and finish are included at each price point.

Its range also covers different practical requirements, not just decorative variations: close-spacing designs for households with pets, laser-cut designs, and scissor-style gates sit alongside simpler metal-plate options.

Best for: Buyers who want the quotation to contain actual fabrication and finishing specifications rather than relying on a catalogue photograph.

5. SG Gate Door Window

SG Gate Door Window takes a different approach, with suppliers offering tightly defined model pricing. Its published mild-steel range sits at roughly S$600–S$1,500, with the company indicating that larger or more intricate work can reach around S$2,000 and above.

That upper end is worth noting because it prevents a misleading comparison between a basic catalogue gate and a genuinely customised one. 

The company also offers a 10-year warranty on its gates, which differs materially from suppliers offering one-year coverage. That does not prove the underlying steel or coating is better, but it makes the warranty terms an important part of the comparison. Buyers should check exactly what the 10 years covers and whether exclusions apply.

Best for: Buyers who want to compare a wider price range and value published warranty coverage.

6. MAGworks Pte Ltd.

Sai Huat is one of the more obviously fabrication-oriented businesses on the shortlist. Its catalogue covers mild-steel gates alongside other metalwork such as railings, grilles and steel-framed architectural work, which makes it a different proposition from a door retailer whose gate is one product category among many.

Its published SH054 modern mild-steel gate is S$550, giving buyers a concrete starting point rather than an unexplained “from” figure. The more interesting reason to consider a fabricator such as Sai Huat is when your opening or design moves outside a standard catalogue requirement.

Best for: Buyers who prefer dealing with a fabrication-focused metalwork company, particularly when the requirement is less catalogue-driven.

How Much Do Mild Steel Gates Cost in 2026?

For a standard HDB mild steel gate, S$550–S$1,100 is a realistic starting range in 2026, while more elaborate laser-cut, laminate-finished or heavily customised designs can push beyond S$1,000. The important part is that these prices are not always like-for-like: one supplier may include measurement, installation, disposal and a mortise lock, while another may charge separately for some of them.

A few current listings show just how wide the spread can be. Renovaid lists standard HDB mild steel gates from S$550 to S$790 for 3ft × 7ft, with site measurement, delivery, installation and disposal included; its 4ft × 7ft example is listed at S$750. BTO Door currently lists standard 3ft × 7ft designs from around S$588–S$788, while more premium laminate-finished models reach S$988.

At the other end, a laser-cut gate from The Door is currently listed at S$799 for 3ft × 7ft and S$899 for 4ft × 7ft, with installation, dismantling and disposal included.

A more useful way to budget

For a typical HDB replacement, think about your budget in three bands:

BudgetWhat to Expect
S$550–S$750Basic catalogue designs and straightforward HDB replacements
S$750–S$1,100More substantial designs, laser-cut patterns or upgraded finishes
S$1,100+Premium finishes, extensive customisation or non-standard requirements

These are market reference bands rather than fixed industry prices. The final quotation depends on the gate dimensions, construction, finish, design and what the supplier includes in the package. Current published examples support the broad spread, but they should not be treated as a universal price list.

The question to ask before paying a deposit

Instead of asking only “How much is the gate?”, ask the supplier for a written breakdown:

Gate + measurement + fabrication + finish + installation + disposal + lock + GST = final price.

Then ask what happens if the measurement shows that your opening is outside the standard size.

That one conversation can tell you more about a supplier than a catalogue full of polished gate photographs. It also gives you a genuinely like-for-like figure to use when comparing the suppliers in this guide.

Who Should Not Buy From a List Like This

This list is not for everyone. Landed automatic gate projects need specialists in larger structures and motor systems. Buyers chasing ultra-cheap Carousell listings should compare the actual steel, finish, installation and hardware before choosing on price alone. 

And if your project requires a fire-rated gate or door, look for a specifically tested and certified fire-rated assembly rather than a standard mild steel gate.

Where to Start?

Shortlist three mild steel gate suppliers willing to put the steel gauge and coating method in writing. Rank them by what they will actually specify and by whether they turn up to measure when promised — not by who ranks for “best gate Singapore”.

Then book measurements with the two suppliers that gave you clear written specifications. The cheapest quote means little if the steel and finish are not clearly defined.

Frequently Asked Questions

How much does a mild steel gate cost in Singapore in 2026?

For a standard 3 × 7 ft HDB opening, published prices start from around S$398 before GST at the promotional end, while many installed gates fall around S$550–S$1,100 depending on the design and finish. Laser-cut, privacy and mesh designs can cost more. AT Aluminium, for example, lists premium work at around S$1,660 and above. A 4 × 7 ft opening may add roughly S$80–S$150.

Don’t compare the headline price alone. Check whether the quote includes measurements, installation, disposal, GST, the lock, and extras such as a bottom kick plate or non-standard colour.

Is mild steel a good material for gates in Singapore’s humidity?

It can be, provided the steel and finish are properly specified. Some local fabricators publish 1.6 mm steel, while cheaper imported gates may use thinner material. Powder coating is also commonly specified for corrosion protection.

The more useful question to ask a supplier is what steel thickness and coating process are included in the quoted price. Pay particular attention to welded joints, cut edges and other areas where the protective finish can be damaged or poorly applied.

Mild steel or wrought iron for an HDB gate?

For most HDB buyers, mild steel offers more flexibility in design and is widely available in modern grille, laser-cut and panel styles. Wrought iron is generally associated with heavier, more decorative designs and is more commonly seen in landed properties.

The choice comes down to the design you want, the weight of the gate, the finish and the budget. For an HDB replacement, compare the actual specifications rather than choosing by material name alone.

Will a mild steel gate take a digital lock?

It can, but the gate needs to be fabricated around the lock’s requirements. Digital locks have specific mortise dimensions, mounting points and clearance requirements, so compatibility should be confirmed before fabrication.

Give the supplier the exact brand and model of the lock you plan to use. Ideally, have the lock specification written into the quotation or order confirmation so there is no need to modify the gate during installation.
