Introduction: The Foundation of Modern Industrial Architecture

In the landscape of industrial and commercial construction, General Purpose FRP Roofing Sheets stand as the fundamental building block for daylighting solutions. These versatile panels represent the perfect equilibrium between performance and practicality, offering reliable illumination for countless applications without unnecessary complexity or premium costs. As the most widely specified category in the FRP market, these sheets have become the default choice for projects where straightforward, dependable daylighting is required.

At ZHUOZHU, we’ve refined our general purpose sheets through decades of manufacturing experience, creating products that deliver consistent performance across diverse applications while maintaining the accessibility that has made them an industry staple.

Core Technology and Construction

Balanced Material Composition

Our general purpose sheets employ a precisely engineered formulation:

Resin Matrix Optimization
We utilize specially formulated G299C/ET2139 grade unsaturated polyester resins that provide the ideal balance between mechanical strength, weather resistance, and cost-effectiveness. These resins offer:

• 125 MPa flexural strength

• 82 MPa tensile strength

• 92 MPa shear strength

• 1.40 g/cm³ density

Reinforcement Architecture
A minimum 22% glass fiber content from premium suppliers like OCV, JUSHI, and CPIC ensures structural integrity while maintaining optical clarity. The reinforcement pattern is optimized to distribute stresses evenly across the panel surface.

Surface Protection System
Every sheet features a 20-micron DuPont Melinex 301 protective film (or equivalent) that provides:

• ≥99% UV resistance

• Anti-static properties for self-cleaning

• Scratch and chemical resistance

• Compliance with AS/NZS 4256 Parts 1&3:2006 standards

Key Performance Characteristics

Optical Excellence

• Light Transmission: 70-72% at 1.5mm thickness

• Light Diffusion: Professional optical surface treatment transforms harsh sunlight into soft, evenly distributed illumination

• Glare Reduction: Eliminates harsh shadows and bright spots that can cause eye strain

Mechanical Reliability

• Temperature Range: -40°C to +120°C operational capability

• Thermal Expansion: 2.6 × 10⁻⁵ cm/cm/℃

• Wind Uplift: Engineered for standard wind load requirements

Longevity and Durability

• Service Life: 20-year performance warranty

• Color Stability: Resists yellowing and degradation

• Maintenance: Virtually maintenance-free with natural rainwater cleaning

Six Compelling Advantages

1. Exceptional Value Proposition

General purpose sheets deliver approximately 85% of the performance of premium specialty sheets at just 60-70% of the cost. This makes them ideal for projects where budget constraints exist without compromising on fundamental quality requirements.

2. Universal Applicability

Designed to perform reliably in most temperate and subtropical climates, these sheets require no special environmental considerations. Their standardized formulation works effectively across:

• Manufacturing facilities

• Warehouses and logistics centers
