We have been deeply engaged in natural granite decorative aggregate processing for 11 years. Green granite gravel 20mm is a characteristic colored aggregate adapted to overseas ecological gardens, ecological building exterior walls, and outdoor leisure venues, and also a popular natural raw material promoted by overseas landscape designers. We process green granite gravel 20mm using primary natural green granite raw stone without adulteration of foreign stones. Through multi-stage crusher layered crushing and multi-layer fine screening to precisely lock the standard particle size of 20mm, it is sent to 4 track drying ovens for constant-temperature dehydration and color locking. Each grain of green granite gravel 20mm has a naturally warm green texture, complete particles without chipping, uniform and translucent color, and no variegated defects such as yellowing or white spots. It has high integration with green plant landscaping and water-based stone-imitation paint, restoring the visual effect of original ecological natural stone.
Cheap green gravel on the market mostly uses artificial dye soaking for coloring, which is very easy to lose color and bleed after long-term outdoor wind and rain, polluting walls and walkway surfaces. Our green granite gravel 20mm relies on the natural green base of the stone itself, with no chemical dyes added throughout the process. It is resistant to UV rays, rain erosion, and sea breeze corrosion, and will not powder or fade after long-term outdoor use, with weather resistance far exceeding ordinary dyed aggregates. This green granite gravel 20mm is supplied year-round to overseas ecological parks, camping bases, pastoral villas, and ecological homestay projects. Its unique natural green tone conforms to the global low-carbon ecological decoration trend, with numerous overseas building materials wholesalers making repeat purchases. Whether for small and medium-sized merchants placing small trial orders for distribution or overseas general contractors purchasing full containers in bulk, we can stably schedule production and deliver.

We have built a complete integrated aggregate processing production line, equipped with 4 track drying ovens, 5 crushers, 10 conveyor belts, 4 sets of mixing tanks and high-speed dispersers, with a stable monthly production capacity of 60-100 tons, capable of simultaneously undertaking multiple containers of large overseas orders for parallel production scheduling. We have our own independent R&D team and hold an invention patent for the integrated stone paint grinding and dispersion device, capable of independently optimizing the complete process of crushing, screening, and drying, and continuously and stably controlling the finished particle size and color standards of green granite gravel 20mm. The factory has complete sets of environmental impact assessment and "three simultaneities" procedures, with closed-loop recovery and treatment of production dust and wastewater. Products comply with environmental building materials access standards of Europe, America, and Southeast Asia, requiring no additional environmental testing materials for export customs clearance.

Packaging and Transportation
Two standardized packaging solutions are set for overseas export orders. Small and medium batch trial orders are packaged in thickened moisture-proof and waterproof cartons, with multiple layers of stretch film wrapped around the box exterior to isolate marine moisture; full-container bulk engineering orders can be customized with solid wood export wooden boxes, with standard solid wood pallets installed at the bottom, adapting to forklift loading and unloading and ocean container stacking, minimizing bumping and moisture damage during transportation. All packaging can be printed with private brand LOGO, product parameters, and marine warning markings according to the needs of overseas agents, meeting private label distribution requirements. In terms of logistics, we can transport goods to the customer-specified port and complete basic customs declaration supporting docking work, reducing overseas customers' cross-border docking processes and saving procurement communication and time costs.
After-sales Service
Dedicated business personnel are assigned to handle full-cycle after-sales inquiries for overseas customers. After the goods arrive at the destination, if there are product quality problems such as green granite gravel 20mm particle size deviation, uneven color, or substandard cleanliness, after customers provide real photos and inspection certificates, we will immediately verify the cause of the problem and arrange free replacement or supplementary shipment of corresponding goods. All series of granite aggregates uniformly enjoy a 1-year warranty period. Quality defects caused by non-human damage during the warranty period shall be fully borne by the factory for processing costs. Only the outer packaging is prone to crushing damage during transportation, while the internal granite gravel particles are hard and intact, not delaying normal construction use; if the outer packaging is severely damaged, we can simultaneously resend supporting packaging consumables to ensure customers' terminal construction experience.
