In China, the construction and DIY markets have a diverse range of putty knives, with certain types standing out in popularity.
Among the blade materials, those made from carbon steel, like 45# and 50#, are quite common. Carbon steel offers a good balance between cost and functionality. It has sufficient hardness to handle regular scraping and spreading tasks in construction projects, such as removing old paint or applying putty. Stainless - steel blades are also favored, especially in environments where corrosion resistance is crucial. They are often used in coastal areas or places with high humidity. The electro - plating quenching treatment on stainless - steel blades not only enhances rust resistance but also gives them a smooth finish, making cleaning easier.
Regarding the handles, plastic - handled putty knives, especially those with a combination of PP (polypropylene) and TPR (thermoplastic rubber), are very popular. The PP provides a sturdy structure, while the TPR offers a soft, non - slip surface. The non - slip patterns on both sides of the handle ensure a firm grip, reducing the risk of accidents during use. This ergonomic design helps to alleviate hand fatigue, even during extended work periods.
In terms of size, putty knives with widths of 1.5" (38MM), 3" (75MM), and 4" (100MM) are widely used. The 1.5" putty knife is perfect for working in tight spaces, like scraping paint from the corners of windows. The 3" and 4" ones are versatile and suitable for general scraping and putty - applying tasks on medium - sized areas, such as patching holes in walls or removing wallpaper.
These popular putty knife types in China are well - suited for various applications, from professional construction work to DIY home improvement projects, meeting the needs of different users across the country.
