Steel-Plastic Grilles
Steel-Plastic Composite Grilles are engineered to deliver exceptional longevity in demanding environments. The robust hybrid structure combines a high-strength carbon steel core with a wear-resistant polymer coating (PP/PE), ensuring outstanding load-bearing capacity (3-5 tons/m² static load) and resistance to deformation under heavy-duty applications. Unlike traditional all-steel grilles prone to fatigue or plastic grilles limited by low rigidity, our composite design achieves a lifespan of 15-20 years with minimal maintenance. The steel skeleton is fully encapsulated in corrosion-resistant plastic, eliminating rust-induced structural degradation. Additionally, UV-stabilized additives in the polymer layer prevent brittleness and color fading, even under prolonged sun exposure.
Specially designed for harsh chemical and humid conditions, Steel-Plastic Grilles excel in corrosion resistance. The seamless polymer coating acts as a barrier against moisture, acids, alkalis, salts, and organic solvents, making them ideal for chemical plants, marine platforms, wastewater treatment facilities, and coastal infrastructure. Rigorously tested under ASTM/EN standards, they withstand pH levels from 2 to 12 and salt spray environments (up to 5,000 hours without blistering). Unlike metal alternatives requiring frequent anti-rust treatments, our grilles maintain structural integrity without coatings or repairs, drastically reducing lifecycle costs.
Applications Showcase These grilles are proven in extreme scenarios: Chemical Zones: Resistant to acid spills and vapor corrosion in electroplating workshops. Marine Settings: Immune to saltwater erosion on offshore oil rigs or docks. Urban Infrastructure: Withstand de-icing salts on bridges and roadways.
