AI image by LocalRankChoosing a window grille in Singapore means weighing two very different approaches: traditional mild-steel or aluminium bars that form a visible barrier, and near-invisible stainless-steel cable systems that keep the view. This shortlist gathers established suppliers of both, spanning HDB, condominium and landed homes, and was compiled by checking each company against its own website. Treat it as a starting point for quotes, not a ranking.
1. Invisible Grille Concept
Invisible Grille Concept installs high-tension stainless-steel cable grilles for windows, balconies, HDB flats and commercial spaces, in fixed, swing, sliding, bi-fold and door configurations. The company describes itself as one of Singapore's pioneering invisible-grille providers, established in 2009, and says each grille is fitted with its own locking system. It markets an anti-rust, anti-dust cable treatment and states that it uses its own installation crew.
2. Endo Grilles
Endo Grilles fits invisible grilles built from 316 marine-grade stainless-steel cable, and also offers aluminium 'Sleek' grilles, cat-proof grilles, window restrictor locks and motorised zip blinds. The company states on its site that it is a BCA-registered contractor working to the CR06 structural workhead, and markets a proprietary UV-stabilised 'All-Weather' cable. Carrying both cable grilles and aluminium alternatives lets it cover households wanting either an unobstructed view or a solid frame.
3. Diamond Grille Systems
Diamond Grille Systems installs invisible grilles in fixed and openable forms, plus specialised cat-, dog-, monkey- and bird-proof configurations. Its distinguishing pitch is an uncoated, Switzerland-made mono-core wire that the company says is considerably harder than standard 304 or 316 stainless steel, and it cites a registered patent and a BCA firm registration. It states that all locks in a home are supplied keyed alike.
4. DeGrille
DeGrille supplies fixed and openable invisible grilles, including casement, bi-fold and sliding types, built from 316-grade stainless-steel cable, and also handles auto gates, awnings and louvres. On its site the company offers a choice of nylon, Teflon or nano cable coatings, each tied to a different warranty length, so buyers can trade coating grade against price. It lists a Changi premises and describes its installers as having several years of grille experience.
5. mc.2
mc.2 supplies fixed and openable (bi-fold, casement, sliding) invisible grilles in 316 stainless steel for HDB, condo, landed and commercial spaces, as part of a wider home-furnishing range spanning blinds, curtains, flooring and outdoor shade systems. That breadth suits homeowners fitting out a whole unit who prefer to source grilles and soft furnishings from a single contractor. The company operates from an Ubi showroom and says it uses in-house installers.
6. Legate
Legate offers invisible grilles as well as ultra-slim and aluminium grilles, mosquito-mesh 'mozzie' grilles and metal gates for HDB, condominium and landed properties. The company describes itself as a local household brand that runs its own in-house installation teams rather than subcontracting the work out. Because it carries both cable-based invisible grilles and slim solid-bar options, it suits buyers still weighing an unobstructed view against a more visible physical barrier.
7. Pang Giap
Pang Giap fabricates and installs slim 6mm mild-steel window grilles, wrought-iron and cat-proof grilles, plus aluminium grilles, gates, railings and soundproof windows. The company says it has more than 30 years of manufacturing and installation experience and describes itself as an HDB- and BCA-registered contractor working from its own factory. Its slim solid-bar grilles are pitched as a stronger, more traditional alternative to cable systems for buyers who want a physical barrier.
8. Ho Ho Door
Ho Ho Door supplies aluminium, slim mild-steel, wrought-iron and cat-proof window grilles in both sliding and casement formats, with a showroom for viewing samples. The company states it has operated since 1976 and describes itself as an HDB-licensed, BCA-registered contractor, making it one of the longer-running grille makers on this list. Its cat-proof grilles use narrower bar spacing aimed at keeping pets from slipping through.

9. SG Gate Door Window
SG Gate Door Window supplies customisable mild-steel window grilles, with wrought-iron and aluminium options, alongside HDB gates, doors and digital locks. The company describes itself as a BCA-approved HDB contractor and, on its site, advertises a 10-year warranty on its gates, doors and windows. It highlights clean welding and finishing on its grille panels as a point of difference.
10. SteelHome
SteelHome builds made-to-order HDB window grilles from aluminium extrusion, offering a wide range of RAL powder-coat colours and anodised finishes plus single- or double-glazed glass panels. Every grille is customised to the buyer's panel count, lattice design and gap sizing rather than sold as a stock unit. The company runs its own factory and showroom and states a one-year warranty on the track mechanism and hardware.
How to choose
- Decide on the grille type first: a solid mild-steel or aluminium grille is a visible physical barrier, while an invisible cable grille preserves the view, and child- or pet-safety needs often settle which fits a given window or balcony.
- Check the contractor's HDB and BCA registration (invisible grilles for high-rise safety fall under structural workheads such as CR06) and ask to see the registration rather than trusting a logo on the website.
- Ask what the cable or bars are actually made of and coated with, since 316-grade stainless steel and the coating type affect rust resistance, and confirm the gap spacing meets your child- or pet-safety needs.
- Get the warranty in writing and read what it covers, because the cable or wire, the frame, and the track or locks are often warranted for different periods rather than under a single headline number.
- Confirm whether the company uses its own installers or subcontracts, insist on an on-site measurement before ordering, and get an itemised quote so you can compare like for like across suppliers.
