Applications
Solid metal sheets are used across construction, M&E, architectural, and commercial projects in Singapore.
Architectural & Interior
Wall cladding, ceiling panels, bulkhead linings, feature walls, column casing, and soffit panels. Aluminium and stainless steel are the most common choices for interior architectural applications due to their finish options and corrosion resistance.
Construction & Structural Fabrication
Mounting plates, base plates, equipment housings, machine covers, general fabrication, and structural brackets. Mild steel is the standard specification for structural fabrication work; surface treatment is applied depending on exposure conditions.
M&E and Electrical
Electrical panel enclosures, trunking covers, M&E equipment panels, and switchboard housings. SS304 is commonly used for wet-area electrical enclosures. Mild steel with powder coating is standard for indoor M&E installations.
Commercial & Retail
Shopfront panels, signage backplates, display fixtures, counter frontages, and retail fit-out components. Brushed SS304 and powder-coated aluminium are frequently specified for commercial interiors.
Outdoor Structures
Sunshade panels, louvre backing sheets, external wall cladding, and screen infill panels. Aluminium and SS316 are preferred for exposed exterior use. GI sheets are suitable for roofing and general outdoor construction where a paint or coating finish is acceptable.
If you need perforated or laser-cut variations of these sheets, we can fabricate those as well.
Solid Metal Sheets vs Alternatives
| Material Type | Key Advantage | Key Limitation | Best For |
|---|---|---|---|
| Solid metal sheet | Full coverage; structural rigidity | Heavier than mesh products | Cladding, enclosures, fabrication |
| Perforated metal sheet | Open area for ventilation and aesthetics | Reduced strength vs solid | Screens, facades, acoustic panels |
| Expanded metal mesh | Lightweight; no waste in production | Not suitable where full coverage is required | Walkways, screens, sunshades |
| Laser-cut panel | Custom pattern; precision cut | Higher cost; longer lead time | Feature panels, decorative screens |
