Perforated Metal in Singapore's HDB Upgrading and Neighbourhood Renewal Projects
Singapore's public housing estates are in a constant state of renewal. Across the island, HDB's suite of upgrading programmes — the Neighbourhood Renewal Programme (NRP), Remaking Our Heartland (ROH), the Home Improvement Programme (HIP), and the Silver Upgrading Programme (SUP) — are systematically refreshing older estates with new amenities, improved connectivity, and upgraded communal infrastructure. Since the NRP's introduction in 2007, more than S$1.5 billion has been committed to 229 NRP projects, with the 16th batch announced in April 2025 covering 17 HDB neighbourhoods at a cost exceeding S$165 million and benefiting over 25,000 households.

Behind every one of these projects is a procurement chain that includes architectural metalwork — covered linkways, void deck screens, bin centre enclosures, lift lobby panels, staircase balustrades, precinct boundary screens, and facade elements across upgraded blocks.
Supply Bay has been supplying perforated metal sheets and panels for HDB-related upgrading projects across Singapore, and this article is specifically written for the contractors, town council project managers, and sub-contractors who are specifying and procuring these materials.
HDB Upgrading Programmes and Metal
Understanding where metals like perforated metal panels and expanded metal panels sit within the upgrading scope requires a brief overview of how these programmes work.
The NRP focuses on block and precinct improvements and is fully funded by the Government. Under the NRP, two or more neighbouring precincts enjoy an upgraded living environment, with residents actively engaged through Town Hall Meetings, dialogue sessions, and surveys to shape the scope of improvements. (Source: HDB). Block-level improvements under the NRP can include new lift lobby tiling at the first storey, improved residents' corners, and more seating areas at void decks. Precinct-level improvements include covered linkways, drop-off porches, fitness corners, and community spaces. (Source: PropertyGuru)
The ROH programme operates at a larger scale — covering the upgrading of town centres, neighbourhood centres and parks, the building of new communal spaces, and improvements to connectivity networks across entire towns. Toa Payoh is currently undergoing ROH works as part of the third batch, alongside Woodlands and Pasir Ris.
Across both programmes, perforated metal appears in a consistent set of applications:
Covered linkway and walkway screens — side panels, end screens, and decorative infill along newly constructed or upgraded sheltered connections between blocks
Void deck and common area screens — enclosures for residents' corners, community spaces, and seating areas at ground level
Bin centre and refuse area enclosures — perforated panels for ventilation while containing visual clutter and odour
Lift lobby wall panels — decorative perforated panels at upgraded first-storey lift lobbies, replacing aging concrete or tile finishes
Staircase and balustrade infill — perforated sheet panels replacing ageing grille or solid infill in block staircases
Precinct boundary and planter box screens — low-level perforated screens defining precinct edges, fitness corners, and garden boundaries
Block facade enhancement panels — decorative perforated cladding as part of the HDB Facade Enhancement Programme, which addresses building facade wear and tear across more than 4,000 HDB blocks islandwide

Supply Bay's HDB and Public Housing Project Experi
Supply Bay has supplied perforated metal and expanded metal mesh for a range of HDB-related and public housing upgrading projects across Singapore. The following are among the projects where our materials have been used.
NRP Chai Chee Road / Chai Chee Avenue — Perforated metal panels supplied for estate upgrading works in the Chai Chee precinct as part of the Neighbourhood Renewal Programme. The Bedok Town Council area projects in Chai Chee represent a typical NRP scope: covered linkway screens, precinct-level enclosures, and void deck improvements requiring durable, low-maintenance perforated metal in materials suited to outdoor Singapore conditions.
HDB ROH Toa Payoh — Perforated metal supplied for estate renewal works in Toa Payoh as part of the Remaking Our Heartland programme. Toa Payoh's ROH works have included the development of a 4km-long nature way along the ring road connecting most of the town, along with the upgrading of neighbourhood centres including Toa Payoh Palm Spring with more seating areas and greenery. Perforated metal panels and screens contribute to the covered structures, boundary enclosures, and amenity furnishing that support this kind of large-scale estate rejuvenation.
Tenteram Vantage BTO — Supply Bay also supplied expanded metal drain gratings for the Tenteram Vantage BTO development, one of the newer public housing projects in the Kallang-Whampoa area. View project →
Procurement Considerations for NRP and ROH Contractors
If you are a main contractor or nominated sub-contractor on an NRP, ROH, or HIP project in Singapore, here is what typically matters most at the procurement stage:
Material submittals and approval: HDB and Town Council projects require material submittals before installation. Supply Bay can provide product data sheets, material certificates, coating test reports, and sample panels to support your submittal package. Allow adequate lead time for the approval process in your programme.
Cut-to-size and installation-ready supply: Standard sheet sizes often do not match the panel dimensions required for specific linkway bays, void deck enclosures, or lobby wall positions. Supply Bay can supply panels cut to your specified dimensions with clean edges, reducing site cutting labour and minimising the exposed cut edges that require touch-up on galvanised material.
Phased delivery: Large NRP projects typically involve multiple precincts and phased construction programmes. Supply Bay can coordinate phased delivery of materials aligned to your block-by-block construction sequence.
Fast lead times: NRP and ROH projects are programme-driven — contractors are working to HDB and Town Council timelines that do not easily accommodate long material lead times. Supply Bay maintains stock of standard perforated metal sheets in common specifications, enabling standard requirements to be fulfilled within 1–2 working days. Custom sizes and finishes are typically ready within 1–2 weeks.
