Frequently Asked Questions: Cast Iron Panel Technology Explained

1. What materials are used in high-performance cast iron panels?: Most modern cast iron panels use either gray iron (ISO EN-GJL-200) for excellent machinability or ductile (nodular) iron (QT400-15, QT450-10) for superior tensile and impact strength. Chemical composition control ensures decorative iron panels meet both mechanical and anti-corrosion requirements.
2. What are the standard sizes and can panels be customized?: Common panel dimensions range from 900–1800mm (length) × 250–600mm (height), with thicknesses of 8–20mm. Custom motifs, thicknesses, and mounting holes are available on request for bespoke fencing or decorative railing panels.
3. Which installation standards or certifications do cast iron fence panels comply with?: Panels typically comply with ISO 9227 (corrosion), ISO 9001 (manufacturing), and local building codes (such as ASTM E985 for railing load). Third-party test certificates (EN10204–3.1) are available on request.
4. How is corrosion resistance assured for exterior applications?: Through multi-stage surface treatments: hot-dip galvanizing or advanced powder coating exceeding 2,000 hours salt spray per ISO 9227. This ensures cast iron panel systems outperform traditional painted steel, even in marine or chemical environments.
5. What is the typical service life and what does your warranty cover?: Service life is 30–50 years in urban/non-aggressive settings; 12–24 months warranty against manufacturing & coating defects is provided. Extended warranty packages and on-site technical support are also available for bulk orders.
6. Can decorative iron panels be integrated with other ornamental elements?: Yes! Our design team assists in integrating floral, geometric, or monogrammed wrought iron gate ornaments directly into custom cast iron panel layouts using advanced CNC or casting techniques.
7. What is your delivery time and after-sales process?: Typical lead time: 7–28 days ex-works for standard/custom decorative iron panels. Robust after-sales: online support, spares inventory, and installation guides in EN/FR/DE/CN.
