All metal components undergo hot-dip galvanizing, zinc plating, or powder coating to ensure corrosion resistance and a service life of 10+ years in outdoor environments.What is the minimum order quantity (MOQ) for sliding gate accessories?MOQ varies by product. Most sliding gate rollers and tracks start from 100–500 sets per order. For mixed container orders, we can combine different products to meet the minimum container requirement. Please contact us for a customized quote based on your specific needs.Can you supply OEM/ODM sliding gate accessories with custom specifications?Yes. We accept OEM and ODM orders. You can provide drawings, samples, or specifications and we will manufacture to your requirements. Custom sizes, finishes (powder coat color, HDG, zinc plate), and packaging are all available. Lead time for custom orders is typically 30–45 days.Are your sliding gate accessories compatible with standard automatic gate openers?Yes. Our sliding gate rollers, tracks, and gear racks are designed to be compatible with major automatic gate opener brands including FAAC, BFT, CAME, Nice, and others. We offer M4, M5, and M6 gear rack modules to match different motor pinions. Please specify your gate opener brand when ordering.What quality certifications do your sliding gate accessories hold?Our factory is ISO 9001:2015 certified. Products are tested to EN 13241 and AS/NZS standards where applicable. We provide material test certificates, coating thickness reports, and salt spray test results upon request. Third-party inspection (SGS, BV, TÜV) can be arranged before shipment.What material is the NR3140W nylon roller made from and is it UV-resistant?The NR3140W is manufactured from engineering-grade nylon (PA66) with UV stabilizer additives, making it resistant to UV degradation and suitable for outdoor applications. The white color is achieved through the base material rather than paint, so it will not chip or peel. The nylon material also provides excellent chemical resistance against common cleaning agents and pool chemicals.What is the load capacity and track compatibility of the NR3140W nylon roller?The NR3140W nylon roller is rated for gates up to 150 kg per pair. It is designed for use with standard U-channel tracks (WTU8 series) with a rail width of 25–30 mm. The roller features a sealed ball bearing insert for smooth, low-noise operation. For heavier gates, we recommend upgrading to our steel sliding wheels (DB or DA series) which offer higher load ratings.Request a quote from HST
