Steel siding outperforms vinyl, composite, and wood in virtually every durability category. It is fire resistant, termite-proof, and significantly more impact resistant than vinyl — meaning it won't dent or crack from hail, flying debris, or accidental impacts the way vinyl siding can. For Quad Cities homeowners who have experienced hail storms or severe thunderstorms, steel siding is the obvious answer.
Steel siding is also exceptionally well-suited to the Iowa and Illinois climate. It handles the region's dramatic temperature swings — from -20°F winter lows to 100°F+ summer highs — without warping, buckling, or degrading over time. The finish is baked on at the factory, not applied as a surface coating, which means the color is integral to the material and far more resistant to fading, chalking, and peeling than painted wood or cheaper alternatives.
Suburban Construction has been installing steel siding throughout Davenport, Bettendorf, Moline, Rock Island, and the surrounding region for decades. We are experienced in proper installation techniques that account for steel's unique thermal expansion characteristics, ensuring a long-lasting, problem-free installation.

Did You Know?
- • Freedom Steel Siding's Kynar coating has a performance additive that results in improved scuff resistance over PVC finishes.
- • Steel siding can be cut with an approved saw blade — making installation faster and easier than fiber cement.
- • Because steel siding is "hung," it floats on the exterior wall for a smoother appearance; fiber cement installs tightly to the wall and can reveal substructure imperfections.
- • Steel siding is 100% recyclable and does not produce silica dust during installation — unlike fiber cement, no dust respirator is required.
