The Zhaoqing Sunda Spring hinge is a self‑closing hinge fabricated from stainless‑steel grade SS304 or SS316, providing corrosion resistance in demanding environments. Each hinge incorporates a built‑in spring that delivers consistent closing torque for automatic door operation. The hinges are supplied in a range of sizes and load capacities, matching the supplier’s standard catalogue. The stainless‑steel construction is finished with a polished surface to reduce friction and wear.
Typical dimensions for these hinges span from 50 mm to 250 mm in length, with a leaf width of 30‑80 mm (typical). Load ratings commonly range from 200 N to 1500 N, and the spring torque is usually between 0.5 Nm and 3 Nm (typical). The hinges meet ISO and CE standards for mechanical performance and fire safety, though specific certificates should be confirmed (standard). An optional passivation treatment can be applied to SS316 hinges for enhanced resistance to chloride‑induced corrosion (typical).
Facility managers, architects and equipment manufacturers select these hinges for fire‑rated doors, commercial entryways and high‑traffic interior partitions. The supplier can provide bulk quantities with flexible minimum order quantities and ships in protective cardboard or wooden crates. Prospective buyers should verify the desired size, load capacity and any required certifications with Zhaoqing Sunda before finalising purchase terms.

Before confirming a purchase, verify the stainless‑steel grade, finish, hinge dimensions, load rating and spring torque against project specifications. Request material test reports, torque verification data and load‑test certificates to ensure the hinges meet performance requirements. If fire‑rating compliance is essential, ask for the relevant CE or fire‑test documentation.
Typical stock items can be prepared for shipment within a short lead time, and the supplier ships from Guangdong ports. Buyers should agree on the incoterm - FOB Shenzhen or CIF to the destination port - and confirm payment terms such as L/C at sight or T/T. Discuss any special packaging or palletisation needs to match logistics arrangements.
Arrange a third‑party inspection before loading to confirm dimensions, surface finish and functional performance of the spring mechanism. Obtain the supplier’s ISO and CE certificates, as well as any fire‑rating test reports, to satisfy import compliance and quality assurance. These steps help minimise risks and ensure the hinges perform reliably after delivery.
