Our black granite chip rock is processed from deep black natural granite raw ore, and is engineering-grade black crushed stone for large-scale engineering and bulk procurement scenarios. The product adopts natural crushing technology, with rough and natural particle shape, pure black throughout without variegated color. After large-area laying, the overall tone is unified, presenting a calm and atmospheric visual effect, making it a preferred material for modern-style landscape engineering, permeable flooring and river slope protection. As a source factory with 11 years of stone production experience, our black granite chip rock locks exclusive black ore sources for mass production, controls color difference from the source, ensures tone consistency of large-batch orders, and can meet the centralized supply demand of hundred-ton engineering projects.
Black granite chip rock has excellent engineering performance. Natural granite has hard texture, compression resistance and wear resistance, can withstand vehicle rolling and high-frequency trampling, and is not easy to break or shed slag after long-term outdoor use. The black tone is dirt-resistant and easy to maintain. Even in dusty and rainy outdoor environments, it is not easy to get dirty, and can restore the original color after rain washing, with extremely low later maintenance cost. Compared with dyed gravel, natural black granite will not fade or decolorize, has longer service life and more guaranteed engineering quality. At present, this product has been widely used in the landscape construction of many commercial plazas, municipal roads and large communities, and both decorative effect and durability have been highly recognized by the project parties.

Quality Control
In response to the color difference control requirements of black crushed stone, we have established a special quality control system. At the raw material end, we lock in fixed ore sources for unified mining and processing to ensure stable tone from the source; during production, each batch is sampled and tested for color uniformity to remove variegated stone materials; before finished product packaging, full inspection is implemented to ensure that the product color difference is controlled within engineering standards. Each batch of products is issued with a quality test report, supporting third-party institutions to conduct on-site inspection, and the product comes with a 1-year warranty.
Supply Strength
We have sufficient stock of black granite chip rock in stock, with a stable monthly production capacity of 60-100 tons. We can undertake hundred-ton large-scale engineering orders and support batch supply according to project progress. Standard products can be shipped in 3 days, and urgent orders can be prioritized for production. The factory has multiple crushing and screening production lines, which can simultaneously ensure the synchronous production of multiple bulk orders, with stable and reliable delivery capacity. For a long time, we have served many municipal engineering and real estate development enterprises, and have rich experience in supplying large customers.
