How To Change Metal Exterior Stair Railings – Many external stairs consist of cast concrete, which makes them both functional and robust. Railings for these staircases are often wrought iron, which adheres firmly to the stairs with special masonry hardware. If your metal railing has deteriorated or corroded, replace it is the best option. Replacing a metal railing requires that you remove the old railing before installing the new one. Remove the old hardware is often a challenge, because the anchors are usually buried deep in the concrete.
Check the bottom of the metal exterior stair railings where it attaches to the concrete and locate the screws that hold it down. Remove the screws, by means of a drill. Check the wall in the home where the rear of the metal stairs installed. Locate the brackets at this location and remove the screws to them in the same way. Lift the metal railing of the way. Remove any remaining metal support posts in concrete steps by cutting them off flush with the concrete. Put on protective eye wear and inserting a cutting blade of a reciprocating saw. Keeps the blade attached to the top of the stairs and cut parallel to the support posts until release. Look at the top of the concrete steps to determine if rust stains are present. If rust is, you brush vigorously concrete with a wire brush until they disappear.
Insert the new exterior stair railings on top of the concrete stairs 2 inches from the side edge. Place the rack on the previous hole to hide them, if possible. However, make sure the screw holes on the railing of solid concrete. Mark each screw hole with a pencil and enter the railing aside. This low 1/4-inch-diameter in masonry drills and creates a 1-5 / 8-inch-deep hole in each selected location. Place new metal railing back into place, and insert a corrosion resistant masonry screws into each screw hole on the rail, with the help of a drill. Attach the wall brackets to the home with more corrosion resistant masonry screws or wood screws unless brick or stone. Open a tub of concrete patching compound if some old holes left. Scoop out some of the patching compound with a trowel and spread it over the hole to fill them.metal stair rail outside
