20mm Granite Gravel

With 11 years of deep engagement in granite aggregate production, 20mm granite gravel is the most versatile basic gravel in our entire product line, adapting to the vast majority of global landscaping, exterior wall coating, and infrastructure procurement needs, and also a regular volume-driven product for overseas building materials wholesalers. We process 20mm granite gravel using pure natural granite raw stone. Through multi-stage crushing and screening to precisely lock the standard particle size of 20mm, it is then sent to track drying ovens to remove internal moisture. Each grain of 20mm granite gravel has regular particles and moderate angularities, with no fine powder or weathered debris. Whether paved alone or mixed with stone-imitation paint, the finished product has uniform and consistent texture.

Low-priced similar gravel on the market generally has problems of excessive fine powder and disordered color differences, which can easily cause wall mottling and whitening after paint mixing. Our produced 20mm granite gravel undergoes double-layer screening for powder removal, with moisture content strictly controlled within the standard range. The raw stone has original tone without artificial dyeing, and is resistant to UV rays and rain erosion for long-term outdoor use, without fading or powdering. Over the years, 20mm granite gravel has been continuously supplied to large domestic coating factories, and simultaneously exported in bulk to Southeast Asia, the Middle East, and European countries, adapting to various scenarios such as residential exterior walls, municipal greening, and park roads. Overseas agents report extremely low terminal rework rates, making it an essential 20mm granite gravel for stable profits in long-term distribution.

1. Civil Building Exterior Walls: Basic aggregate for high-rise residential and self-built house stone paint and sand-in-water coatings, replicating natural stone facades

2. Municipal Greening Engineering: Large-area filling and landscaping for urban parks, road green belts, and square flower beds

3. Park Road Paving: Aggregate for factory walkways and community leisure paths, wear-resistant and anti-slip, reducing construction costs

4. Water Treatment Filter Media: Filling for rainwater collection tanks and small water purification equipment, corrosion-resistant with stable filtration performance

The factory covers an area of 4,300 square meters with 23 professional production technicians on duty. 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 scheduling production for multiple containers of large overseas bulk orders. 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 crushing and drying processes, and continuously and stably controlling the finished product quality of 20mm granite gravel. The factory has complete sets of environmental impact assessment and "three simultaneities" procedures, with closed-loop treatment of production dust and wastewater. Products comply with environmental building materials access standards of multiple countries, requiring no additional environmental testing materials for export customs clearance. With 11 years since establishment focusing on the granite aggregate sector, we have long-term stable supply to leading coating enterprises such as Nippon Paint, 3Trees, and SKK, and possess sufficient practical experience in delivering large overseas projects.

Full-line OEM/ODM contract manufacturing services are available. For 20mm granite gravel, we can adjust particle angularity thickness, screening cleanliness, and outer packaging style, supporting printing of customers' private brand LOGO. After customers provide drawings or physical samples, the R&D team completes custom sample delivery within 2 weeks. Samples are free, and only freight collect is charged; the minimum order quantity is 100 kilograms, and multiple sizes and colors of gravel can be mixed in the same order, reducing trial order costs for overseas small and medium-sized agents. Standard spot goods can be produced and shipped within 3 days, customized products completed within 7 days. Bulk long-term purchases can enjoy tiered discounts, effectively reducing overseas customers' long-term procurement costs.

We have established a full-process closed-loop quality inspection system. Each batch of 20mm granite gravel undergoes complete physical and chemical testing according to international building materials industry standards after production, with complete inspection reports issued, and we fully accept third-party inspection institutions to conduct on-site random inspection. 100% manual full inspection is performed before packaging, screening out particles with color differences, fragmentation, and excessive fine powder to ensure highly uniform particle size and color of the entire container of goods. Products uniformly come with a 1-year warranty. The aggregate is hard solid particles, and only the outer packaging wooden pallets and cartons may be crushed and damaged during sea transportation, while the internal materials are intact and do not affect construction. The moisture content index is strictly controlled throughout the production process, fundamentally avoiding after-sales problems such as material caking and wall whitening in overseas humid storage environments.
