Aluminum step down is a coated aluminum sheeting like the traditional aluminum stagger sheets used in all canopies. Unlike canvas, aluminum awnings are white on the interior, greatly increasing reflective light into any space. Aluminum awnings will not rot and with proper care will last indefinitely. Our broad color selection enables you to enhance a space by blending with exterior color schemes. A paint enamel is baked onto the sheeting, providing a color that can withstand the elements. Aluminum is an environmentally friendly product and a smart investment that protects homes and patio, provides shade and reduces energy costs. Most colors are available in 31in. x 12' and 31 in x 24ft and .2in gauge.
