Premium Expanded Clay Pellets LECA Suppliers and Factory in China
Our premium Expanded Clay Pellets, also known as LECA (Lightweight Expanded Clay Aggregate), are engineered for high-performance applications in modern horticulture and industrial construction. By utilizing high-quality natural clay fired at precise temperatures, we create a durable, porous medium that provides an ideal balance of aeration and water retention, ensuring optimal root development and structural stability.
Designed for versatility, these red clay balls excel in hydroponics, aquaponics, and water treatment systems. With exceptional thermal insulation, anti-corrosion properties, and high strength, our LECA pellets offer a sustainable and efficient solution for growers and engineers seeking a lightweight medium that resists freeze-thaw cycles and maintains long-term structural integrity.

Frequently Asked Questions
Q: What makes Expanded Clay Pellets ideal for hydroponics?
LECA provides an ideal balance of oxygen and water. Its porous structure allows roots to breathe while retaining enough moisture and nutrients to support healthy plant growth without soil.
Q: Can these clay balls be reused in different gardening projects?
Yes, due to their high strength and anti-corrosion properties, Expanded Clay Pellets can be cleaned and sterilized for reuse in multiple planting cycles.
Q: How does the "Rate of Floatage" affect my application?
A high floatage rate (95%) is essential for aquaponics and water treatment, ensuring the medium stays buoyant and allows for maximum water circulation.
Q: Are these products suitable for large-scale construction?
Absolutely. Their lightweight nature and thermal insulation properties make them a preferred choice for lightweight concrete and insulating fill in construction.
Q: What is the difference between Muscovite and Phlogopite Mica in mineral products?
While LECA is clay-based, our other mineral offerings include Muscovite (clearer, high insulation) and Phlogopite (darker, higher heat resistance), serving different industrial needs.
Q: Do you provide customized packaging for wholesale orders?
Yes, we offer comprehensive OEM services, including customized labels and packaging options such as PP bags or jumbo bags based on customer requirements.
