Import Door Handle-4-80 — Buy in Bulk from Supplier in China

The Door Handle-4-80 is a commercial-grade door handle designed for heavy-use environments, featuring a solid zinc alloy body with a powder-coated finish to resist corrosion and abrasion. The handle measures 80 mm in length with a 25 mm diameter spindle, and accepts standard 57 mm backset mortise locks. The mounting plate is 120 mm wide and 15 mm thick, with pre-drilled holes for M4 screws. These dimensions align with common industrial door hardware standards for retrofit installations.

The base material is die-cast zinc alloy, typical for high-volume commercial hardware, offering structural rigidity without the cost of stainless steel. The finish is electrostatically applied powder coating in satin nickel, a standard option for institutional settings where fingerprint resistance and low maintenance are priorities. Unlike polished brass or chrome-plated variants, this finish does not require periodic polishing and resists tarnishing under high humidity conditions. The internal spring mechanism is rated for 200,000 cycles per manufacturer testing, consistent with ANSI/BHMA A156.2 Grade 2 performance benchmarks.

This handle is commonly specified for schools, hospitals, and office buildings where durability and code compliance matter more than decorative appeal. Buyers include facility managers, construction contractors, and government procurement departments sourcing for bulk installations. Trade terms are typically FOB Ningbo Port, with MOQ starting at 500 pieces per finish. Packaging is in bulk cartons of 25 units, with foam inserts to prevent surface scratches during transit. Lead times are approximately 25 days after deposit confirmation.

Ningbo Xinye Hardware Tools Manufacturing Co., Ltd. is a supplier based in Ningbo, China, focused on metal hardware for commercial doors. The company is listed as an imported supplier with harbor trust tier, indicating it has passed basic export compliance checks but has no public verification of factory audits or certifications. Its response rate and average response time are not recorded, suggesting limited buyer communication support. The listing does not state factory size, workforce, or export history.

The company appears to operate as a manufacturer or assembler of door hardware, producing items like this handle under private label arrangements. There is no evidence of in-house R&D, product testing labs, or branded product lines. The absence of response metrics and certification claims suggests a low-touch, bulk-supply model rather than a service-oriented distributor. Buyers should confirm production capacity and quality control procedures directly before placing orders.
