Devli Green Slate is a popular Indian natural stone that is known for its unique green color and durability. It is commonly used for various applications including flooring, wall cladding, roofing, and paving. In terms of heavy use areas, it can indeed be used in such environments.

The durability of Devli Green Slate depends on the quality and thickness of the stone. When using it in heavy use areas, it is important to ensure that it is sourced from a reliable supplier and is of high-quality. Thicker slabs tend to have better durability and can withstand heavy foot traffic or other heavy loads.

However, it is essential to keep in mind that like any natural stone, Devli Green Slate can still be subject to wear and tear over time. Regular maintenance and care, such as sealing the stone to protect it from stains and periodic cleaning, are crucial to preserve its appearance and longevity.

If properly installed and maintained, Devli Green Slate can be used in heavy use areas without any significant issues. It is always advisable to consult with a professional stone supplier or installer who can assess the specific requirements of the space and guide you in selecting the appropriate thickness and finish of the slate for heavy use areas.
