Import Door Handle-4-73 — Buy in Bulk from Supplier in China

The Door Handle-4-73 is a stainless steel door handle designed for modern architectural applications, constructed from 304-grade austenitic stainless steel to resist corrosion and maintain appearance under continuous use. It has a backset of 57 mm, a spindle diameter of 8 mm, and a handle length of 115 mm with a projection of 50 mm. The design is flush-mounted with concealed screws, offering a minimalist aesthetic suitable for contemporary interiors.

The material is 304 stainless steel, which contains 18% chromium and 8% nickel, providing superior resistance to rust and staining compared to lower-grade alloys. Surface finishes include brushed satin and mirror-polished, both mechanically finished rather than coated. The internal mechanism uses a spring-loaded latch system with a steel torsion spring, rated for 200,000 cycles of operation per ANSI/BHMA A156.2. These features align with commercial-grade hardware standards.

This handle is commonly selected by architects for hotels, hospitals, and high-end residential developments where hygiene and durability are critical. Buyers include interior design firms, general contractors, and procurement departments managing large-scale renovations. Trade terms are typically FOB Ningbo, with packaging in individual polybags within cartons of 30 units. MOQ is not specified but is likely flexible for repeat buyers with established accounts.
