基本信息
This precision granite straight edge is a professional high-precision measuring tool crafted from natural Jinan blue granite, a premium material selected for its high density, low water absorption, and excellent dimensional stability. Before processing, the raw ore blocks undergo 2-3 years of natural aging treatment to completely eliminate internal stress, ensuring that the product will not deform during long-term use or storage. It is designed for detecting straightness, flatness, and alignment in various precision manufacturing and installation scenarios, providing reliable and accurate measurement data for enterprises. Compared with traditional cast iron measuring tools, this granite straight edge features non-magnetic properties, rust-free corrosion resistance, and minimal thermal deformation, making it ideal for high-precision measurement environments where clean, stable testing conditions are required.
