How to Choose the Right Sheet Metal for Durability

Understanding Sheet Metal Durability Factors

When evaluating sheet metal type for long-term performance, consider three critical factors: corrosion resistance (measured by ASTM A123 zinc coating standards), tensile strength (typically 300-550 MPa for structural grades), and environmental adaptability. Galvanization and specialized coatings can extend service life by 15-20 years in harsh conditions.

1. Galvanized Corrugated Steel Sheet

Widely used in roofing and agricultural buildings, galvanized corrugated steel sheet offers:

• Zinc coating (60-275 g/m² per ASTM A653)
• Natural water drainage via corrugation
• 30-50 year lifespan with proper maintenance

Best for: Coastal areas (salt resistance), budget-conscious projects where G90 coating provides adequate protection.

2. Profiled Steel Tile Type

These architectural-grade metals combine durability with aesthetic flexibility:

Requires hardware compatibility – use stainless steel fasteners to prevent galvanic corrosion.

3. Pipe Type Structural Systems

Circular and rectangular hollow sections (CHS/RHS) excel in:

• High strength-to-weight ratio (per EN 10219 standards)
• Torsional resistance for seismic zones
• Clean appearance for exposed structures

Pair with wire mesh infill for composite wall applications requiring ventilation.

Comparative Analysis

Sandwich composite board type vs traditional options:

• Thermal efficiency: 60% better than single-layer metals
• Installation speed: 40% faster than layered systems
• Cost: 15-20% premium offset by reduced labor
