How to Build a Desk With a Galvanized Steel Top

Sand the top of two three-shelf bookcases with coarse-grit sandpaper. The bookcases act as the base for the desk, giving you storage space for paperwork, decorative objects and other items. Rub the sandpaper over the top of each wood bookcase, removing the finish from the wood and leaving behind a rough or gritty surface.

Place the two bookcases a few feet apart and set a plywood board measuring ¾ inch by 24.5 inches by 36 inches on top. Move the bookshelves so each sits flush with the side edges of the plywood. Position the bookcases so that the shelf sides face outward.

Paint a layer of wood glue on the top of one bookcase with a foam paintbrush. Repeat this on the top of the second bookcase. Arrange the plywood board on top of the bookcases. Clamp the plywood to the cases and let it dry overnight. Remove the clamps.

Sink 1-inch wood screws through the plywood and into the bookcases. Place the screws every 2 inches, securing the plywood to the top of the bookcases.

Cover the top of the plywood with epoxy, using a paintbrush for a smooth layer. Lay a sheet of 24.5-by-36-inch galvanized steel on top of the plywood. Carefully smooth down the steel top, removing any air trapped between the plywood and steel. Secure the steel to the plywood with clamps. Leave the clamps in place for at least two hours, giving the glue time to dry. Remove the clamps.
