B decking is one of the most used structural decking in the construction industry, and is valued for its strength-to-weight ratio, versatility and ease of use. Our 22ga panels measure 3' wide by 24' long with 1.5"deep channels and are built to span open distances of up to 6'6". The panels also have a galvanized finish to help protect against rust and corrosion. In addition to being an ideal roofing support surface, B-decking can also be used as awnings, wind-breaks, or decorative barriers. These panels can be ordered in custom lengths and are also available with a gray primer coat applied (for panels that will be painted).
