Steel Structure Building Wall and Roof Panel Comparison

Choosing the right wall and roof panels is critical for durability, insulation, and cost efficiency in steel structures. Below is a detailed comparison of common panel types, their materials, applications, and performance in different environments.

1. Wall Panel Types

Panel Type	Material/Structure	Thickness	Key Features	Best For	Pros	Cons
Single-Skin Metal	Galvanized steel or aluminum	0.4–1.2 mm	Lightweight, low cost, minimal insulation.	Sheds, warehouses in mild climates.	Cheap, easy to install.	Poor insulation, prone to condensation.
Sandwich (Insulated)	Steel skins + PIR/PUR/rock wool core	40–200 mm	High thermal/acoustic insulation, fire-resistant.	Cold storage, offices, HVAC buildings.	Energy-efficient, durable.	Higher cost, heavier.
Corrugated Metal	Galvanized or coated steel	0.5–1.5 mm	Ribbed design for strength, water shedding.	Agricultural buildings, industrial.	Affordable, weather-resistant.	Limited insulation, noisy in rain.
Fiber Cement	Cement + cellulose fibers	6–12 mm	Fireproof, termite-resistant, mimics traditional finishes.	Fire-prone areas, aesthetic projects.	Non-combustible, low maintenance.	Heavy, brittle, requires skilled install.
Composite Panels	Metal + plastic/wood core	20–100 mm	Aesthetic versatility, moderate insulation.	Commercial façades, retail.	Lightweight, customizable.	Durability concerns in UV/humid climates.

2. Roof Panel Types

Panel Type	Material/Structure	Thickness	Key Features	Best For	Pros	Cons
Standing Seam	Pre-painted steel/aluminum	0.7–1.2 mm	Raised seams for watertight joints, sleek appearance.	High-wind/rain regions (e.g., cyclones).	Excellent weather resistance, long lifespan.	Higher cost, specialized installation.
Trapezoidal	Galvanized steel	0.5–1.0 mm	Corrugated profile for rigidity, cost-effective.	Industrial sheds, garages.	Affordable, easy to install.	Prone to leaks without sealants.
Insulated Metal (IMP)	Steel skins + foam core	50–150 mm	Integrated insulation, vapor barrier.	Temperature-controlled spaces.	Energy-saving, noise reduction.	Expensive, requires precise joints.
Polycarbonate	Multi-wall translucent sheets	4–16 mm	Natural light diffusion, UV-resistant.	Greenhouses, skylights.	Lightweight, high light transmission.	Poor insulation, scratches easily.
Stone-Coated Steel	Steel base + stone granules	0.4–0.7 mm	Mimics traditional tiles, impact-resistant.	Residential/commercial roofing.	Aesthetic, durable.	High cost, heavy.

3. Cladding and Weatherproofing Options

Feature	Wall Panels	Roof Panels
Weather Resistance	- Fiber cement resists hail.	- Standing seam handles heavy rain.
Insulation (R-Value)	- Sandwich panels: R-5 to R-8/inch.	- IMPs: R-6 to R-8/inch.
Wind Uplift Resistance	- Corrugated panels: 120–150 mph.	- Standing seam: 160+ mph.
Fire Rating	- Fiber cement: Class A.	- IMPs: Class A (with fire-rated core).
Lifespan	- Galvanized steel: 30–50 years.	- Stone-coated steel: 50+ years.

4. Cost Comparison

Panel Type	Wall Cost (per m²)	Roof Cost (per m²)
Single-Skin Metal	10–10–20	15–15–25
Sandwich/IMP	30–30–60	40–40–80
Corrugated/Trapezoidal	12–12–25	15–15–30
Polycarbonate	20–20–40	25–25–50
Stone-Coated Steel	40–40–80	50–50–100

5. Environmental and Regional Suitability

• Coastal/Humid Areas:

  • Use galvanized steel or aluminum with PVDF coatings to resist salt corrosion.

  • Avoid fiber cement (absorbs moisture).

• Cyclone-Prone Regions (e.g., Madagascar):

  • Roofs: Standing seam or mechanically seamed trapezoidal panels (wind uplift rating ≥ 160 mph).

  • Walls: Insulated sandwich panels with reinforced fasteners.

• Cold Climates:

  • IMP roofs (R-8+) and sandwich walls to retain heat.

---

6. Installation and Maintenance

• Ease of Installation:

  • Corrugated panels are simplest for DIY.

  • Standing seam requires specialized tools/crews.

• Maintenance:

  • Galvanized steel: Inspect for rust every 5 years.

  • Polycarbonate: Clean annually to prevent UV degradation.

Recommendations by Use Case

1. Warehouse in Cyclone Zones:

   • Walls: Insulated sandwich panels (100 mm PIR core).

   • Roof: Standing seam with concealed fasteners.

2. Cost-Effective Industrial Shed:

   • Walls/Roof: Corrugated galvanized steel.

3. Cold Storage Facility:

   • Walls/Roof: IMPs with polyurethane foam (150 mm).

4. Aesthetic Commercial Building:

   • Walls: Composite panels (woodgrain finish).

   • Roof: Stone-coated steel.

Key Takeaways

• Durability: Standing seam roofs and sandwich walls excel in harsh climates.

• Budget: Corrugated/trapezoidal panels offer the best value for non-insulated needs.

• Sustainability: IMPs reduce long-term energy costs but have higher upfront expenses.

• Local Compliance: In Madagascar, prioritize wind-rated panels and corrosion-resistant coatings (e.g., PVDF).
