Fiberglass Grating


About product

Marine fiberglass grating, or FRP grating, is a preferred choice for ship decks and step bridges due to its numerous advantages. Firstly, it offers a significant reduction in deck weight, leading to increased cargo capacity and improved operational efficiency. Secondly, it acts as a protective barrier, effectively preventing the intrusion of various mediums and offering excellent resistance to corrosion caused by exposure to seawater. By utilizing marine fiberglass grating, ships can optimize their performance while ensuring long-lasting durability and minimizing maintenance requirements in demanding marine conditions.

Product Detail

Fiberglass Grating For Dry Docks

Fiberglass grating is extensively used in marine applications, including dry docks. Dry docks are facilities where ships and boats can be lifted out of the water for maintenance, repairs, or storage. The FRP Grating finds multiple uses in dry docks due to its specific characteristics and benefits:

  • Dry Dock Flooring: Fiberglass grating serves as an excellent flooring option in dry docks. Its corrosion resistance makes it ideal for withstanding the harsh marine environment, including exposure to saltwater and chemicals. The open mesh design allows water and debris to pass through, preventing accumulation and maintaining a clean work area.
  • Maintenance and Repair Platforms: Dry docks require sturdy platforms for workers to access different areas of the vessel during maintenance and repair tasks. FRP grating provides a durable and slip-resistant surface for these platforms. Its lightweight nature facilitates easy installation and reconfiguration as required.
  • Walkways and Catwalks: This marine grating is commonly used for walkways and catwalks throughout the dry dock facility. These walkways provide safe passage for workers, allowing them to move around the dry dock while performing tasks. The anti-slip surface of fiberglass grating ensures traction, even when wet or oily, reducing the risk of accidents.
  • Drainage Systems: Efficient drainage is crucial in dry docks to remove water, spills, and other fluids. FRP grating with its open mesh design allows for effective drainage, preventing the accumulation of water and maintaining a dry and safe working environment.

The Performance Of Fiberglass Grating

Fiberglass grating delivers outstanding performance with its exceptional features:

  • Enhanced carrying capacity: The integrated molding design improves the marine grating’s ability to handle heavy loads effectively.
  • Improved load-bearing capacity: The cross-designed bearing structure disperses forces, resulting in significantly increased load-bearing capabilities.
  • Easy to clean: The smooth and non-stick surface of fiberglass grating resists dirt and grime, making it easy to maintain a clean and hygienic environment.
  • Superior anti-corrosion protection: The combination of fine glass fibers and polyester resin tightly interwoven together provides excellent resistance to corrosion, ensuring durability even in corrosive conditions.
  • Lightweight and efficient: With a hollow area comprising 70% of its volume, fiberglass grating offers a lightweight solution without compromising strength or performance.

In addition, the FRP grating offers the following advantages:

  • Excellent corrosion resistance: It withstands the damaging effects of chemicals and saltwater, ensuring long-lasting performance.
  • Fire retardant: It possesses inherent fire-resistant properties, enhancing safety in fire-prone environments.
  • Easy fabrication: Its lightweight nature and versatility allow for easy customization and installation according to specific project requirements.
  • Low maintenance: Fiberglass grating requires minimal upkeep, saving time and costs associated with maintenance tasks.
  • Long service life: Its durable construction ensures a prolonged lifespan, providing reliable performance for an extended period.
