Accurate measurement depends not only on precision manufacturing, but also on how easily measurements can be read in real working conditions. That’s why we developed our new light yellow stainless steel π tape (diameter tape), designed to improve visibility, durability, and usability in both workshop and field environments. 

The new light yellow stainless steel diameter tape,it’s resolution:0.02mm /.001” ，（0.01mm / .0005” available upon request）, measuring range from Ø50mm / 2” to Ø9600mm /384” （larger size tape available upon request）,made of stainless steel 301 or spring steel 65Mn. 

Unlike traditional bright or matte stainless steel pi tapes, the light yellow surface makes scale markings easier to read by increasing contrast while reducing glare under strong lighting or direct sunlight. This makes daily diameter and circumference measurement faster, easier, and more comfortable for operators who rely on clear readings throughout the day. 

The upgraded surface treatment also improves corrosion resistance, helping the tape perform reliably in humid and industrial environments without compromising measurement accuracy. 

Manufactured using high-quality stainless steel and precision scale marking technology, this Pi tape is ideal for pipe measurement and general industrial diameter measurement applications.
