FRP LADDER STEP TROLLEY (PREMIUM)

FRP (Fiber Reinforced Plastic) Ladder technical specifications typically include a variety of factors that ensure strength, durability, and safety. These ladders are made of a composite material, combining fiberglass and resin, and are often used in environments where metal ladders would corrode or fail due to environmental conditions. Below are the typical technical specifications for FRP ladders:

1. Material Composition:

• Fiberglass: Typically, E-glass fiberglass is used for strength and durability.
• Resin: A thermoset resin, such as polyester or vinyl ester, is used for bonding the fiberglass strands.
• Non-conductive: FRP ladders are non-conductive, making them ideal for electrical work or hazardous environments.

2. Dimensions:

• Height: Available in various sizes, typically ranging from 2 feet (600 mm) to 40 feet (12 meters) or more.
• Rung Spacing: Usually 12 inches (300 mm) to 16 inches (400 mm).
• Width: Standard widths typically range from 12 inches (300 mm) to 20 inches (500 mm), depending on the ladder’s load capacity.

3. Load Capacity:

• Industrial Rating: Typically ranges from 225 lbs (102 kg) to 375 lbs (170 kg), depending on the ladder design.
• Heavy Duty Rating: Some ladders may be designed for heavier loads, up to 500 lbs (227 kg) or more.
• Safety Factor: Generally, FRP ladders are designed with a safety factor of 4:1.

4. Strength:

• Breaking Strength: The ladders are designed to withstand significant impact and torsional stress, with breaking strength values exceeding 1500-3000 lbs (680-1360 kg).
• Flexural Strength: 14,000 psi (96 MPa) to 20,000 psi (138 MPa).

5. Safety Features:

• Slip-Resistant Rungs: The rungs are often coated with a non-slip material such as grit or a textured surface to prevent slipping.
• Spreader Bars (for extension ladders): These are used for stability when the ladder is extended.
• Non-Conductive: FRP ladders are highly resistant to electrical currents, making them ideal for electricians or work near power lines.

6. Design Types:

• Step Ladders: Common, self-supporting ladders used for low-height access.
• Extension Ladders: Extendable ladders designed for reaching higher places.
• Straight Ladders: Fixed-length ladders that lean against structures.
• Platform Ladders: Have a larger platform at the top for stability during prolonged work.

7. Corrosion Resistance:

• UV Resistance: FRP ladders are resistant to UV radiation, preventing degradation from sunlight exposure.
• Weather Resistance: Highly resistant to chemicals, salts, and moisture, making them suitable for outdoor or industrial use.
• Fire Resistance: FRP is generally non-flammable and may meet specific fire resistance ratings (e.g., ASTM E84).

8. Standards and Certifications:

• OSHA (Occupational Safety and Health Administration): Ladders comply with OSHA regulations for industrial use.
• ANSI (American National Standards Institute): ANSI A14.5 standard for ladders.
• UL (Underwriters Laboratories): Some FRP ladders are UL-listed for electrical use.

9. Temperature Range:

• FRP ladders can generally operate in a wide temperature range from -40°F (-40°C) to 200°F (93°C).

10. Weight:

• FRP ladders are lighter than metal ladders. Weight typically ranges between 10-50 kg depending on the size and design.

11. Environmental Suitability:

• Ideal for wet and hazardous environments, such as chemical plants, power stations, and areas with high electrical risks.

These ladders are valued for their lightweight, strength, corrosion resistance, and electrical insulation properties. When selecting an FRP ladder, it's important to verify the exact specifications based on the intended use, load capacity, and any relevant industry standards.
