Fiberglass Reinforced Plastic (FRP) Marker Stakes, Warning Stakes, and Identification Stakes

I. Material and Craftsmanship

1. Material Composition
   Composed of resin (polyester/epoxy) as the matrix, glass fiber as the reinforcing material, and additives such as calcium powder, it combines lightweight and high-strength characteristics‌13.

2. Manufacturing Process
   Utilizes processes like pultrusion and compression molding, with surface treatments including screen printing, UV printing, and laser engraving to ensure clear and durable markings‌35.

3. Specifications

• Dimensions: Common widths of 80mm×80mm or 50mm×50mm, with customizable height‌57

• Thickness: Standard 3-6mm, special requirements up to 8-10mm‌5

• Colors: Standard colors include yellow (warning), red (high alert), white (indication), and green (specific areas)‌35

II. Performance Features

1. Lightweight and Easy Installation
   Specific gravity only 1/4 that of steel, facilitating transportation and quick installation‌46.

2. Corrosion and Aging Resistance
   Resistant to water, acid, alkali, salt, and other chemical corrosion, suitable for acidic/alkaline soils and harsh climates, with a lifespan of 30-50 years‌24.

3. High Strength and Impact Resistance
   Tensile strength ≥160MPa, bending strength ≥190MPa, ring stiffness ≥50kPa, resistant to deformation upon impact‌16.

4. Insulation and Safety
   High insulation resistance prevents leakage currents, stable dielectric performance at high frequencies, suitable for electrical facilities‌14.

5. Theft Prevention and Environmental Friendliness
   Material has no recycling value, naturally theft-resistant; production process is non-toxic and eco-friendly, complying with national environmental standards‌
