Raw Material Selection and Quality Control for Five-Lotus Stone Curbs

The raw materials for the Wulian Road curb stones primarily come from the abundant Wulian Marble mines in Wulian County, Shandong Province.

However, the quality of the raw materials directly determines the lifespan of curb stones.

Therefore, when selecting raw materials, strict control must be maintained over the texture, grain, and hardness of the stone to ensure the selected material meets production requirements.

During the processing, strict control over the quality of cutting, polishing, and rounding corners must be maintained to ensure the flatness and perpendicularity of the product.

In addition, conducting strict inspections and筛选 of raw materials, eliminating stones with cracks, color discrepancies, and other defects, is also a key factor in enhancing the quality of Wuhualian road curbs.
