Preparing the Wall Surface
Before installing corrugated steel siding, the wall surface must be properly prepared to ensure a smooth, durable installation. Begin by removing any old siding, loose paint, or debris that might interfere with the new panels. The substrate should be clean, dry, and structurally sound.
If the wall framing is exposed, inspect it for any damage or rot and replace any compromised sections. It’s essential to have a flat and even surface because corrugated steel siding will closely follow the contours of the underlying structure. Uneven surfaces can lead to poor panel alignment and water infiltration.
Next, install a weather-resistant barrier (WRB) such as house wrap or building paper. This barrier will protect the wall from moisture and improve energy efficiency. Overlap the WRB seams according to manufacturer instructions, typically 6 to 12 inches, and secure it with staples or cap nails.
Install vertical furring strips or a rain screen system over the WRB to provide an air gap between the siding and the wall. This gap promotes drainage and ventilation, reducing the risk of mold and corrosion. Furring strips should be made from treated wood or metal and spaced at 16 to 24 inches on center.
Measuring and Cutting Panels
Accurate measurement and cutting are critical to achieve a professional finish with corrugated steel siding. Always measure the wall height and width at multiple points because walls may not be perfectly square or level.
When cutting panels:
- Use metal shears, an angle grinder with a cut-off wheel, or a power saw equipped with a metal-cutting blade.
- Wear appropriate safety gear, including gloves, eye protection, and hearing protection.
- Cut panels slightly longer than needed to allow for trimming after installation.
- Deburr sharp edges with a metal file or grinding wheel to prevent injury and improve appearance.
Cut panels from the backside to minimize visible scratches on the finished surface. For openings such as windows and doors, cut panels to fit around frames, leaving a small clearance for expansion and contraction.
Installing Corrugated Steel Panels
Begin installing corrugated steel siding at a corner or edge, working horizontally across the wall. Follow these best practices for installation:
- Start with the bottom row, aligning the first panel square to the wall.
- Use galvanized or stainless steel fasteners with neoprene washers to prevent corrosion and water penetration.
- Fasten panels through the high ridges of the corrugation to minimize water infiltration.
- Space fasteners approximately 12 to 16 inches apart along the panel edges and every 24 to 36 inches in the field.
- Overlap adjacent panels by one or two corrugations, depending on the profile, to ensure a tight seal.
- Use a chalk line to keep panels level and straight as you progress upward.
When fastening panels, avoid overtightening screws, which can deform the metal and compromise the seal. The neoprene washer should be compressed but not flattened.
Sealing and Finishing Touches
Proper sealing enhances the durability and weather resistance of your corrugated steel siding installation. Use high-quality sealants and flashing materials at edges, corners, and around openings.
- Apply a continuous bead of exterior-grade silicone or polyurethane caulk along seams and panel overlaps where water intrusion is a concern.
- Install metal or vinyl flashing at corners, window and door trims, and the base of the siding to divert water away from the structure.
- Use closure strips made of foam or rubber to seal gaps between panels and framing, especially at the top and bottom edges.
- Paint or touch up any cut edges or scratched areas with a matching rust-resistant paint to prevent corrosion.

Preparing the Surface and Tools Needed for Corrugated Steel Siding Installation
Before installing corrugated steel siding, it is essential to prepare the surface properly and gather the necessary tools to ensure a smooth and secure application. Proper preparation enhances the durability and appearance of the siding.
Surface Preparation:
- Inspect the wall framing: Ensure the wall studs or framing are structurally sound, straight, and evenly spaced, typically 16 or 24 inches on center.
- Install a moisture barrier: Apply a weather-resistant barrier such as house wrap or felt paper over the sheathing to prevent water infiltration behind the siding.
- Install furring strips (if required): Attach vertical furring strips to the wall to create a flat, even surface and allow airflow behind the siding, which helps prevent moisture buildup.
- Check for obstructions: Remove or trim any protrusions like vents, electrical conduits, or pipes that could interfere with siding installation.
