While Venus Granite is a durable and attractive material, it may not be the most suitable choice for exterior deck stairs. Granite is known for its strength and resistance to wear, making it a popular option for countertops and interior flooring. However, using granite for outdoor stairs comes with a few considerations:
1. Slippery Surface: Granite can become slippery when wet. This can make it hazardous for outdoor stairs, especially during rainy or snowy conditions.
2. Thermal Variations: Granite is sensitive to extreme temperature changes. Exposure to constant sunlight and heat, followed by freezing temperatures, can cause the material to crack or break over time.
3. Cost: Venus Granite can be quite expensive compared to other materials commonly used for exterior stairs such as concrete, wood, or even composite decking materials.
Considering these factors, it may be more practical and cost-effective to choose a material specifically designed for outdoor stairs, such as pressure-treated wood, composite decking, or concrete. These options tend to be more slip-resistant, durable, and better suited for withstanding outdoor elements.
