Scale indicators5 records

Recent moves5 records

Expansion highlights4 records

Emerging players

• Gerard Roofs (Roofing Group): Gerard Roofs supplies metal tile-look roofing in NZ — adjacent rather than identical to Dimond's long-run tray profiles, but competing for the same residential re-roof and architectural segments where aesthetics matter.
• KingFlor / Fielders (BlueScope): Fielders (BlueScope) manufactures roll-formed steel decking and roofing profiles including architectural tray systems in Australia — comparable to Dimond's structural and architectural offerings but primarily serving the Australian market.

Direct peers

• Lysaght (BlueScope): Lysaght, part of BlueScope Steel, manufactures roll-formed steel roofing and cladding products (e.g., Colorbond, TRIMDEK) across Australia/NZ and competes head-to-head with Dimond on long-run metal roofing profiles.
• ATAS International: ATAS International is a US-based manufacturer of metal roofing, cladding, and ceiling systems with roll-formed profiles and architectural standing-seam products comparable to Dimond's Eurotray and Dimondek ranges.
• Metalcraft Roofing: Metalcraft Roofing manufactures and distributes metal roofing, cladding, and rainwater products across NZ via its own branch network, directly competing with Dimond in residential, commercial, and rural roofing segments.
• Roofing Industries: Roofing Industries is one of NZ's largest metal roofing and cladding manufacturers, offering comparable roll-formed profiles, rainwater systems, and a national branch network — a direct competitor in the same product categories and customer segments as Dimond.
• Steel & Tube: Steel & Tube is a major NZ-based manufacturer and distributor of metal roofing, cladding, and fastening products with national coverage — a direct peer in product offering, channel model, and customer base to Dimond.

Regional players

• Euroclad: Euroclad is a UK-based manufacturer of architectural metal roofing and cladding profiles with comparable concealed-clip and tray systems (e.g., Eurospan) — a regional peer operating in a different geography but offering directly comparable product technology.

Others

• Zincalume / GalvSteel (Steel mills): NZ Steel's Zincalume branded coated steel is a key substrate used across the NZ roll-forming industry; comparable to Dimond at the upstream material layer where competition and pricing are set.
• COLORSTEEL® (NZ Steel): NZ Steel is the upstream supplier of the Colorsteel pre-painted steel substrate that Dimond roll-forms; comparable because it sits at the same point in the NZ metal roofing value chain and supplies competing roll formers.
