The coil spring compression spring offered by Qingdao Pingyang International Trading Co., Ltd. is made from stainless steel spring wire and is designed for caster and castor wheel assemblies in industrial, furniture and equipment applications. The spring features a wire diameter range of 0.1‑8 mm and an intermediate diameter of 11.4 mm, with a zinc plating finish that improves corrosion resistance. Multiple stainless steel grades such as SUS301, SUS302, SUS304 and SUS316 are listed, allowing buyers to select the alloy that best matches their performance needs. The product is presented as a bulk‑ready component suitable for export‑oriented sourcing programmes.
In the spring manufacturing sector, stainless steel wire of the listed grades is standard for components that must retain strength while resisting rust in humid or chemical environments. Zinc plating is a typical surface treatment that adds an extra barrier against moisture, extending service life for caster‑wheel springs used in warehouses and manufacturing floors. The wire‑diameter tolerance is normally held within ±0.02 mm, and the intermediate diameter is controlled to ensure consistent spring rate across production batches. Quality control includes 100 % inspection before shipment and adherence to ISO 9001 and RoHS standards, which are common benchmarks for reliable spring products.
Typical buyers include furniture manufacturers, material‑handling equipment producers and industrial equipment assemblers who require dependable compression force in wheel assemblies. The supplier highlights flexible customization - material, wire diameter, surface treatment, inner and outer diameters, free length, total coils and active coils can be adjusted on request. Trade terms such as FOB or CIF are mentioned, but exact pricing, MOQ and lead‑time details must be obtained directly from the supplier. Shipping originates from the Qingdao facility in Shibei District, offering convenient access to major sea routes for international importers.
