What is a top hat batten?

A top hat batten is a length of cold-formed steel shaped like the silhouette of a formal top hat in cross-section: a flat crown sitting above two horizontal flanges that flare out on either side. The flanges fix down to the structural frame (truss, joist, or stud); the crown sits up off the frame, ready to carry whatever’s attached on top — ceiling lining, roof sheeting, wall cladding.

That simple geometry is what makes steel top hat battens so useful in modern Australian building. The raised crown gives the batten stiffness along its length, the flanges give your fixings a reliable, repeatable bite into the frame below, and the gap underneath lets air and condensation move where they need to.

Why builders specify top hat battens

Top hat battens have become the default profile across Australian residential and commercial builds for four practical reasons:

Stiffness without weight.

The raised crown acts as a structural rib. Carries more load per metre than a flat strip of the same gauge.

Easy, repeatable fixing.

The two flat flanges give self-drilling screws a clean bite into the frame below. Same fixing line every time.

Built-in ventilation
gap.

The crown sits proud of the frame by 22mm or 40mm. Air and moisture move through, reducing condensation risk.

Dimensionally consistent.

Cold-formed steel keeps its dimensions over time. Won’t warp, twist or shrink like timber battens do.

Kspan top hat batten sizes

Kspan fabricates steel top hat battens in two crown sizes, each engineered for a specific job in the build. Both share the same top hat profile family — same flat crown, same two flanges — just sized differently for what they need to carry.

22mm / Ceiling

22mm Top Hat — Ceiling Battens

Section 22-42, BMT 0.42mm. Sized to carry plasterboard, timber lining and decorative ceiling panels across the structural frame above. Lighter profile, tighter spacing.

  • Crown: 22 mm

  • BMT: 0.42 mm

40mm / Roof

40mm Top Hat Battens — Roof

Section 40-55, BMT 0.55mm. Sized to carry roof sheeting, wind load and foot traffic. The 40mm top hat battens are our most-specified roof product.

  • Crown: 40 mm

  • BMT: 0.55 mm

Outside the two standard sizes, Kspan can fabricate custom top hat battens on request — different crown widths, BMTs, lengths and quantities — for builds with non-standard requirements. Send us your spec and we’ll quote.

Standards and compliance

Every Kspan top hat batten is manufactured to the Australian Standards that govern cold-formed steel, loading codes, and roof/wall cladding design:

  • AS/NZS 4600 — Cold-Formed Steel Structures (The Master Document for Top Hat Batten Design)

  • AS 1397 — Steel Sheet & Strip, G550 MPa Steel (The Material We Form From)

  • AS 1170 Series — Loading Codes (The Loads Our Span Tables Design Against)

  • AS 4055 — Wind Loads for Housing (The Wind Region Context)

  • AS 1562.1 — Design and Installation of Sheet Roof and Wall Cladding

QUICK ANSWERS

Top Hat Battens Adelaide – Frequently asked questions

Kspan supplies two standard sizes: 22mm crown (used as ceiling battens) and 40mm crown (used as roof battens). The 40mm top hat battens are our most-specified product overall — the size most builders come asking for by name. Other crown widths and BMTs are available on request.

Yes — our roof battens are top hat battens. “Top hat” describes the profile shape; “roof batten” describes the application. Kspan’s 40mm top hat battens are designed and span-rated specifically as roof battens.

Yes. Outside the two standard sizes, we can fabricate custom top hat battens with non-standard crown widths, BMTs, and lengths. Useful for non-standard residential builds, specialist commercial applications, or one-off requirements where the standard sizes don’t fit. Send us your spec for a quote.

Kspan top hat battens are fabricated from G550 high-tensile steel to AS 1397. BMT (base metal thickness) varies by application: 0.42mm for 22mm ceiling battens, 0.55mm and 0.75mm for 40mm roof battens. The G550 grade gives the batten its strength at thin gauges.

Yes — we despatch across metro Adelaide, the Adelaide Hills, regional South Australia, and beyond. For larger orders we coordinate delivery directly to site. For smaller orders, pickup from our Adelaide facility is available. Send us your delivery address with your quote request and we’ll confirm freight at the same time.
