Import C50 Putty Knife Steel Strip — Buy in Bulk from Supplier in China

The C50 Putty Knife Steel Strip is a precision-engineered tool component manufactured from spring steel grades such as 65Mn, 1065 and SAE1055. These grades deliver the resilience and edge retention required for professional putty and plaster work, with the 65Mn variant offering high elasticity for repeated flexing without deformation. The strip is supplied in custom lengths and thicknesses to match specific putty knife designs, ensuring a tight fit and consistent performance across applications in construction and renovation.

Material composition is standard carbon spring steel, typically heat-treated to achieve a hardness range of 45 to 55 HRC for durability against abrasive compounds. The steel is finished to a smooth, burr-free edge to prevent snagging during application, with a typical surface roughness of Ra 0.8 to 1.6 micrometres. Industry practice for these strips includes a zinc or phosphate coating to resist corrosion during storage, though uncoated variants are available for applications where bare metal is preferred.

Contractors and DIY professionals use the strip in putty knives for applying, smoothing and scraping fillers, adhesives and plaster. Common trade terms include FOB or CIF, with packaging typically in bundles of 100 to 500 pieces per carton. Buyers should confirm the exact length, thickness and coating requirements to match their knife models, as well as the supplier’s ability to provide custom sizes for specialized tools.
