Hardware cloth is a sturdy woven mesh made of metal wire. It’s often used in construction and repairs as a protective barrier or screen. When installed properly, hardware cloth can keep out pests like rodents and birds while still allowing air and light to pass through. There are many different types of hardware cloth available, so it’s important to choose the right one for your needs. For example, if you’re using it to keep out pests, you’ll need a mesh with small openings that they can’t squeeze through. If you’re using it as a screen or barrier, you’ll need a mesh with larger openings to allow air and light to pass through. Hardware cloth is available in a variety of materials, including galvanized steel, aluminum, and stainless steel. It also comes in different gauges or thicknesses. The thicker the gauge, the stronger the wire mesh will be.
