Introduction: Meeting the Unique Challenges of Long-Span Structures

Large-span steel structures—the dramatic roof systems that define modern stadiums—present unique coating challenges. Thermal expansion and contraction occur over greater distances, structural flexure is more pronounced, and maintenance access is often difficult or impossible. FLD’s long-lasting coating for large-span steel structures in stadiums is engineered specifically for these demanding applications.

Core Benefits

Accommodates Structural Movement

Flexible coating film moves with the structure, maintaining adhesion through thermal cycling and load-induced deflection.

Difficult-Access Durability

Extended service life eliminates the need for frequent maintenance in hard-to-reach areas of long-span structures.

Comprehensive Barrier Protection

Thick-film system provides robust protection against moisture ingress, preventing hidden corrosion in enclosed structural sections.

Design Life Matching

Coating durability matches the 50-year design life typical of major stadium structures.

Key Features

High-Flex Formulation

Elongation exceeding 200% accommodates structural movement without cracking.

High-Build Application

Thick coats (200-300 microns per layer) provide robust protection with fewer application passes.

Water and Moisture Resistance

Impermeable barrier prevents condensation-induced corrosion inside enclosed sections.

UV and Weather Resistance

Topcoat resists UV degradation and maintains appearance on exposed structural elements.

Application Areas

• Space frame roof structures
• Truss and arch systems
• Cable and suspension systems
• Cantilever roof elements
• Long-span girders
