Measuring the magnesium alloy is to create a new material, by the state of scientific research, metrology department recommended for the production of light square feet, has great advantages. 
 Mg-Al square feet for inspection, measuring, marking, equipment installation, industrial construction works. 
 Mg-Al square feet features: light weight, less than 2 meters 1.5kg / m, 2 m above the 3kg / m. A 6-meter square feet only 18 kilograms, a person can check the use of light. Easily deformed: general music service point of steel material is 30kg/mm2, cast iron music service point 38kg/mm2, and magnesium alloy to achieve 110kg/mm2, equivalent to 3-4 times, played a resistance to bending, the deformation is not easy effect, magnesium aluminum flat feet bending targets far beyond the other materials. 
 Mg-Al square feet easy storage: hanging, flat can, and will not affect its long flat straight line, parallel. And magnesium light show raw square feet is not easy: do not oiled during use, long-term is not used, stored, when gently coated with a thin layer of oil to general industrial.
