These ball caps add an elegant decorative touch to fence posts while protecting them from weathering and corrosion. Made from cast aluminium alloy for durability. Easy to install. Available in natural aluminium or powder coated finishes. OEM/ODM orders accepted.Typical ApplicationsResidential FencingCommercial FencingGarden GatesSecurity FencingFAQWhat aluminium alloy grade do you use for your fence accessories?We use ADC12 (A380) die-cast aluminium alloy for most decorative accessories, which provides excellent fluidity for complex shapes and good corrosion resistance. For structural components, we use 6061-T6 or 6063-T5 extruded aluminium. All alloys are RoHS compliant and free from lead and cadmium.What surface finishes are available for aluminium accessories?Available finishes include powder coating (any RAL color, 60–80 µm), anodizing (natural silver, black, bronze, gold, 15–25 µm), liquid paint, and raw (unfinished) for customers who apply their own finish. Powder-coated aluminium accessories are UV-resistant and suitable for coastal environments.Can aluminium fence accessories be customized with our logo or design?Yes. We offer full OEM/ODM service for aluminium accessories. Custom designs can be produced from your drawings or 3D files. New mould tooling cost is typically USD 500–2,000 depending on complexity, and is amortized over the first production run. Sample lead time is 20–30 days after mould approval.Are your aluminium accessories suitable for coastal or high-humidity environments?Yes. Aluminium naturally forms a protective oxide layer, making it inherently corrosion-resistant. Our powder-coated aluminium accessories pass 1,000-hour salt spray tests (ASTM B117), making them suitable for coastal, tropical, and high-humidity environments where steel accessories would corrode.What is the MOQ for aluminium fence accessories?MOQ for standard aluminium accessories (finials, post caps, spear tops) starts from 500–1,000 pieces. For custom OEM designs with new tooling, MOQ is typically 2,000–5,000 pieces depending on unit size. We can combine different accessory types in one shipment to help meet container minimums.How are the 50x50mm cast aluminium ball top caps secured to the fence posts?Our 50x50mm ball top caps are designed for a snug friction fit over standard 50x50mm square posts, but we highly recommend securing them with industrial-grade construction adhesive or color-matched self-tapping screws for a permanent hold. The base of each cast aluminium cap features precise inner dimensions to ensure a secure, rattle-free fit on your fencing systems.What are the standard packaging options for bulk orders of the 50x50 post ball caps?For B2B wholesale orders, the cast aluminium ball caps are typically packed individually in protective poly bags and placed into heavy-duty corrugated export cartons to prevent scratching and transit damage. We also offer secure palletized shipping for large volume orders and can accommodate custom retail packaging requirements, such as branded boxes or barcode labels, for our distributor partners.Request a quote from HST
