For industries requiring color-coated steel sheets that combine rigorous performance standards with extensive color selection, JSW Radiance has emerged as a preferred solution. This technical examination explores the product's specifications, coating systems, and testing protocols that make it suitable for diverse applications.

JSW Radiance color-coated steel sheets comply with IS 15961 and IS 15965 standards, ensuring quality in both substrate and coating. The substrate offers strength options of 550 Mpa or 345 Mpa, with thickness ranging from 0.3-1.5mm and maximum width of 1550mm to accommodate various dimensional requirements. An aluminum-zinc alloy coating weighing 150-200 g/m² provides superior corrosion resistance and extended service life.

Available in the complete RAL color spectrum with custom color options, JSW Radiance supports design flexibility across applications. The product offers multiple coating systems:

• RMP (Regular Modified Polyester): A cost-effective solution for applications with moderate weather resistance requirements.
• SMP (Silicon Modified Polyester): Provides enhanced weather resistance compared to RMP, offering balanced performance and value.
• SDP (Super Durable Polyester): Features exceptional UV resistance and gloss retention for demanding environments.
• PVDF (Polyvinylidene Fluoride): The premium option with superior UV resistance, corrosion protection, and self-cleaning properties for extreme conditions.

The coating structure employs a dual-layer design: a minimum 25-micron top layer of primer plus polyester coating and a minimum 10-micron epoxy primer backing, enhancing both corrosion protection and coating adhesion.

• Salt spray resistance: SDP/PVDF coatings withstand ≥1000 hours
• Solar Reflectance Index (SRI): ≥80 (color-dependent)
• Scratch hardness: 1.5-2/1-1.5 kg
• Adhesion: 100% via cross-cut testing
• Formability: 2T for soft coatings, 4T for hard coatings
• Chemical resistance: ≥100 MEK rubs (non-metallic), ≥80 (metallic)
• Operating temperature: Up to 140°C

• Construction: Roofing, cladding, fenestration, and building envelopes
• Appliances: Exterior panels for refrigerators, washing machines, and air conditioners
• Transportation: Interior and exterior components for automotive, rail, and marine applications
