Scrap iron grading tools

Abstract

This invention relates to a scrap iron grading measuring tool, which mainly consists of a thin card with several measuring ports, providing a convenient tool for measurement. The scrap iron grading measuring tool is a card body with a length measuring scale on one long side and measuring ports of 3mm, 16mm, and 1mm openings on one short side. When this invention is used to measure the thickness of scrap iron, the thickness range (less than 1mm, between 1mm and 3mm, or more than 3mm) can be determined by measuring the thickness of the scrap iron through the different sized measuring ports on the short side of the card body, thereby classifying the scrap iron into grades for subsequent recycling operations. When measuring the length of scrap iron or greater thickness, the length measuring scale on the long side of the card body is used. This invention integrates several measuring dimensions on the same card body, corresponding to scrap iron recycling grading standards, effectively shortening the measurement time during recycling.

Claims
