FAQ
Q: What materials and weather resistance does this Carbon Steel Heavy Duty Hinge have?
A: The hinge is made of high-quality Q235 carbon steel (ASTM A36 equivalent) with electroplating (zinc/nickel) or hot-dip galvanizing surface treatment. It passes a 48-hour salt spray test, is corrosion-resistant and rust-proof, and can adapt to outdoor temperatures of -40℃~60℃, suitable for long-term use in yards, farms, and industrial areas.
Q: What is the load capacity of the hinge, and how to choose the right size?
A: The load capacity ranges from 80kg to 150kg per hinge (depending on thickness: 5mm/6mm/8mm). For gates weighing 100-200kg, we recommend 6mm thick hinges; for gates over 200kg, choose 8mm thick ones. Leaf sizes (75x50mm/100x75mm/125x100mm) can be selected based on gate frame thickness (30-80mm).
Q: What installation methods are supported, and is it compatible with different gates?
A: The hinge supports weld-on and bolt-on installation (mounting hardware included). It is universally compatible with wood, PVC, iron, and steel gates, especially suitable for American-style fence gates, garden gates, and industrial workshop doors. No professional skills are required for installation-only basic tools like drills and wrenches are needed.
Q: Do you accept customized orders, and what is the MOQ?
A: Yes, we provide OEM/ODM customization services, including customizing size, thickness, surface color, and logo engraving. The minimum order quantity (MOQ) is 100 pieces, and bulk orders can enjoy preferential pricing. For special customization requirements, please contact our sales team for technical solutions.
Q: Does the product have relevant quality certifications, and what after-sales services are provided?
A: The Carbon Steel Heavy Duty Hinge complies with ISO 9001, CE, and ROHS certifications, meeting European and American industrial standards. We provide a 10-year quality guarantee (against material and craftsmanship defects) and 24/7 technical support. If there is any quality problem, we offer replacement or refund services.
