제품 성능 소개

FRP Pultruded Grating (Fiber Reinforced Plastic Pultruded Grating) is a high-strength, corrosion-resistant grating product manufactured using a pultrusion process. This process involves pulling continuous glass fiber strands through a thermosetting resin matrix—such as polyester, vinyl ester, or epoxy—followed by a heated die to form rigid, structural profiles. These profiles are then assembled using cross rods and adhesives or mechanical fastening to form grating panels.

Pultruded FRP grating is designed to withstand heavy loads and is ideal for applications requiring long spans. It typically offers superior mechanical strength compared to molded FRP grating, making it a suitable alternative to traditional materials such as steel or aluminum, especially in corrosive or moisture-prone environments.

Key advantages include exceptional resistance to chemicals, UV radiation, and moisture, making it suitable for use in offshore platforms, chemical plants, wastewater treatment facilities, and other harsh industrial settings. It is also non-conductive, lightweight, and easy to install, reducing labor and transportation costs.

Available in various resin types, surface finishes (such as anti-slip grit), and bearing bar configurations (I-bar, T-bar, etc.), FRP pultruded grating can be customized to meet specific requirements, including load-bearing needs, open area preferences, and environmental conditions. Fire-retardant and anti-static options are also available for specialized applications.

문의

자주하는 질문

질문 : What is the difference between pultruded and molded FRP grating? ㅏ : Pultruded FRP grating is made from continuous fiberglass strands pulled through a resin bath and shaped into profiles, offering higher strength and longer span capabilities. Molded FRP grating is cast in a mold, with equal strength in both directions but lower span capacity compared to pultruded grating.
질문 : What are the advantages of using FRP pultruded grating over steel grating? ㅏ : FRP pultruded grating is corrosion-resistant, lightweight, non-conductive, non-magnetic, and requires minimal maintenance, unlike steel, which can rust and is heavier and conductive.
질문 : In what environments is pultruded grating most commonly used? ㅏ : It is ideal for chemical plants, offshore platforms, wastewater treatment facilities, walkways, trench covers, and any corrosive or electrically sensitive environments.
질문 : How is pultruded grating installed? ㅏ : It is installed using stainless steel clips, fasteners, or bolts depending on the structure. Panels can be easily cut on-site with carbide tools and installed with minimal labor.
질문 : Is FRP pultruded grating fire-retardant? ㅏ : Yes, fire-retardant versions are available, especially those made with vinyl ester or phenolic resins, which can comply with ASTM E84 Class 1 fire ratings.
질문 : Can FRP pultruded grating handle heavy loads? ㅏ : Yes. Pultruded grating is designed for heavy-duty applications and can withstand high loads across longer spans, especially when using I-bar or T-bar configurations.
질문 : What surface finishes are available for safety? ㅏ : FRP pultruded grating can be manufactured with gritted (anti-slip) surfaces, concave tops, or even covered plates to enhance slip resistance and worker safety.
