What is the difference between the half of the positive hole and the half of the large hole of the welded mesh?

Half welded mesh (1/2 welded mesh) means that the hole spacing of the welded mesh is half an inch, that is, the two holes of the square hole welded mesh are exactly one inch, 2.54 cm,

so the hole spacing of the half welded mesh with the right hole is 1.27 cm.

But in fact, the hole spacing of the half welded mesh used in the market is about 1.5 cm. This is the so-called concept of "right hole" and "large hole":

"Right hole 1/2" and "large hole 1/2", "right hole 3/4" and "large hole 3/4", "right hole 1 inch" and "large hole 1 inch" all mean this. This is also the result of the reasonable adjustment of the specifications of the product after a long period of practical application, especially when the welded mesh is used as a wall crack prevention mesh and wall plastering mesh, the effect of the right hole and the large hole is not much different, but the large hole can reduce some costs. The specific specifications still depend on the customer's requirements. After all, the use of the welded mesh cannot be generalized.
