Corrugated Sheets

Corrugated Roofing, Cladding & Architectural Sheets in Singapore

Supply Bay supplies corrugated metal sheets in aluminium, mild steel, galvanised steel and stainless steel (SS304 / SS316) for roofing, wall cladding, fencing, ceiling panels, and architectural feature applications.

Corrugated sheets are produced by cold-rolling flat metal sheet into a repeating ridge-and-valley profile. This corrugation process significantly increases the sheet's structural rigidity and load-bearing capacity relative to its weight, making corrugated metal one of the most efficient and cost-effective cladding and roofing materials for industrial, commercial, and architectural use.

Supply Bay's corrugated sheets are available in standard profiles and custom cut lengths, with optional finishing including powder coating and PVDF coating.

The Supply Bay Standard

  • 4FT x 8FT (1.22m W x 2.44m L) standard sized sheets or 5FT X 10FT (1.53m W × 3.05m L). Custom cut lengths available to specification.

  • Materials: Aluminium sheets, Mild Steel sheets, Galvanised Steel (GI) sheets , Stainless Steel (SS304, SS316) sheets

Add-Ons

  • Additional protective finishes for exterior applications

  • Additional powder coating or PVDF coating finishes

Corrugated Sheet Profiles

Supply Bay supplies corrugated sheets in two standard profiles: sinusoidal (round wave) and trapezoidal (IBR / Box Rib).

  • Sinusoidal (Round Wave)

    A smooth, continuous S-curve wave repeating across the sheet width. No flat sections or angular transitions.

  • Trapezoidal (IBR / Box Rib)

    Flat-topped ribs with angular sides and flat valley sections.

Applications

Corrugated metal sheets are used across a broad range of construction, industrial, and architectural applications in Singapore:

  • Roofing: Industrial factory roofs, warehouse roofing, covered linkways, canopy structures, agricultural buildings, and site offices. Corrugated profiles direct rainwater runoff efficiently.

  • Wall cladding and facade panels: External wall cladding for industrial and commercial buildings. Architectural corrugated cladding is increasingly used on contemporary commercial and institutional facades for its textured, industrial aesthetic.

  • Ceiling and soffit panels: Corrugated aluminium sheets used as decorative ceiling elements in retail, F&B, and commercial interiors, where the ribbed profile adds visual texture and depth.

  • Fencing and hoarding: Corrugated galvanised steel sheets for construction site hoarding, perimeter fencing, industrial boundary walls, and temporary enclosures.

  • Feature walls and interior design: Corrugated stainless steel and aluminium panels used as feature wall cladding in contemporary retail, hospitality, and residential interiors.

Supply Bay Metals

Supply Bay supplies corrugated metal sheets in galvanised steel, aluminium, mild steel, and stainless steel (SS304/ SS316) for roofing, cladding, architectural, and industrial applications across Singapore. We supply both standard profile sheets and custom cut-to-length panels, with finishing options including powder coating and PVDF. Our local supply capability ensures reliable lead times without the extended delays of overseas procurement.

Laser Cut Metals FAQ

  • Supply Bay supplies corrugated sheets in galvanised steel (GI), aluminium, mild steel, and stainless steel (SS304 and SS316). Please note that depending on the design and complexity, some materials are more appropriate for bending than others. Our team can advise on the correct grade for your project.

  • There are two types of corrugated sheets.

    • Sinusoidal (round wave) profile has smooth, symmetrical ridges and valleys.

    • Trapezoidal or IBR (Inverted Box Rib) profiles has flat-topped angular ribs with steeper sides.

    Corrugated profiles are more commonly specified for architectural and light-commercial applications; trapezoidal profiles are preferred for longer spans and heavier industrial roofing. Contact us to discuss which profile suits your application.

  • Yes. Corrugated sheets in mild steel, galvanised steel, and aluminium can be powder coated in any RAL or custom colour.

    For long-life facade applications on aluminium, PVDF coating is recommended for superior UV and fade resistance.

  • Yes, when correctly specified. Galvanised steel and aluminium corrugated sheets are well-suited to Singapore's outdoor environment.

    For coastal locations or highly corrosive environments, aluminium or SS316 stainless steel are the preferred specifications.

  • All Supply Bay corrugated sheets are manufactured to order based on customer specifications. A CAD drawing (DXF, DWG, or equivalent) is required to proceed with fabrication.

    • Standard panel size: 4ft × 8ft (1.22m × 2.44m)

    • Custom cut-to-size: Available on request.

    • Lead time: 1–2 weeks.
