Explore our targeted range of corrugated metal profiles engineered for robust architectural, agricultural, and industrial structural builds across NZ.
Designing structures in New Zealand means building for some of the world's most dynamic geological and meteorological environments. From coastal geothermal zones in the North Island to heavy snow loads and active seismic fault lines in the South Island, roofing materials must meet the strict requirements of NZS 3604 (Timber-framed buildings) and AS/NZS 2728 (Prepainted sheet metal products).
Corrugated steel sheets—historically known as corrugated galvanized iron (CGI)—remain the quintessential roofing and cladding material for Kiwi residential homes, dairy sheds, and commercial structures. However, basic imports often fail premature aging tests under New Zealand's harsh UV index and marine salt spray.
"New Zealand's atmosphere is classified under ISO 9223 corrosion categories ranging from C3 (Medium) to C5-M (Very High Marine). Specifying the incorrect coating mass or alloy composition is the leading cause of premature material failure."
Our manufacturing processes are calibrated directly to ocean transportation protocols and localized performance standards, ensuring peace of mind from container loading to site installation.

Formulated to support the flexible displacement dynamics required to withstand high peak-acceleration earthquakes in regions like Canterbury and Wellington.
Our custom light-gauge, high-tensile profile structural designs minimize building dead weight while maintaining maximum wind resistance loads.
100% recyclable steel substrates to align with modern green building standards and NZ Green Building Council (NZGBC) initiatives.
Ningbo Puppet Steel Co., Ltd. is a professional Steel Sheet Manufacturer | Cold Rolled, Hot Rolled & Galvanized Steel Supplier committed to providing high-quality steel products and customized metal solutions for customers worldwide. Serving industries such as construction, infrastructure, manufacturing, automotive, energy, home appliances, and industrial equipment, the company has built a strong reputation for reliable products and consistent service.
Located in Ningbo, China, Puppet Steel operates advanced processing and manufacturing facilities equipped with modern production lines and precision quality inspection systems. Our geographic location adjacent to the Port of Ningbo-Zhoushan—the world's busiest port by cargo tonnage—allows us to offer streamlined sea freight routing with direct vessels arriving at Auckland, Tauranga, and Lyttelton.
With extensive industry experience, the company offers flexible OEM and customized manufacturing services to meet various project requirements. From material selection and cutting to surface treatment and packaging, every production stage is carefully managed to ensure product consistency, dimensional accuracy, and long-term performance. Strict quality control procedures are implemented throughout the manufacturing process to comply with international standards and customer specifications.
Puppet Steel focuses on delivering durable, corrosion-resistant, and cost-effective steel products suitable for demanding applications in both domestic and international markets.
For modern logistics hubs, transport hubs, and multi-span commercial offices, we manufacture high-yield structural framing along with 24/26-gauge high-tensile cladding. This structural combination provides superior span-to-weight ratios, keeping steel framing light and highly resilient during seismic shifts.
Kiwi architectural trends demand clean, modern, and energy-efficient materials. Our prepainted steel lines feature customized modern color palettes matched to coastal themes, utilizing advanced heat-reflective pigments to lower residential indoor temperature fluctuation and cooling bills.
Dairy farming facilities and produce packhouses face demanding micro-climates. High humidity, animal waste runoff, and harsh sanitization compounds demand specialized high-zinc CGI or ASA-coated alternative profiles to extend structural service lifespans and avoid regular panel replacement.
To eliminate compliance risks under New Zealand building consent procedures, Puppet Steel operates a comprehensive checking system that ensures structural and chemical integrity:

Expert answers addressing compliance, delivery logistics, and material selection for importing corrugated steel to the NZ market.
Yes. All of our structural and prepainted steel coils are manufactured under strict QA systems that conform precisely to AS/NZS 1397 (for metallic-coated steel) and AS/NZS 2728 (for prepainted steel products). Mill Test Certificates (MTC) stating mechanical properties, grade, and coating weight are provided with every shipment.
For high-corrosion zones close to ocean shorelines (ISO Category C4 and C5), we recommend a minimum coating mass of Z275 (275g/m² zinc) or AZ150 (150g/m² Aluzinc). These barriers offer localized galvanic protection at exposed cut edges and prevent red rust propagation.
Our manufacturing lead time ranges from 15 to 25 days depending on specification and color customization. Transit time from Ningbo Port to Auckland or Tauranga generally averages 18 to 25 days, with direct shipping lines optimizing the process.
We supply steel in specific structural grades such as G300 (ideal for custom bending and profiles requiring structural ductility) and G550 (high-tensile steel designed to resist large snow and wind load forces). Standard tensile tests are performed on every production run to ensure compliance with architectural designs.
Maintaining state-of-the-art cold-rolling and galvanizing lines to ensure dimensional consistency and long-term durability.
