How to use fiber optic grating clips

Fiber optic or FRP grating clips are stainless steel fasteners used to secure fiberglass grating panels to support structures or to connect adjacent panels, ensuring stability and corrosion resistance.

Purpose and Function

Fiber optic grating clips are designed to secure molded or pultruded fiberglass grating panels to supporting structures, preventing movement, minimizing differential deflection under load, and extending the service life of the grating. They can also fasten adjacent panels together, maintaining alignment and structural integrity.

Materials and Corrosion Resistance

Most grating clips are made from stainless steel types 304, 316, or 316L, providing excellent resistance to corrosion in industrial, chemical, and marine environments. This makes them suitable for outdoor or harsh conditions where traditional carbon steel fasteners may fail prematurely.

Types of Clips

There are several main types of FRP grating clips, each suited for specific applications: L Clip: Secures grating to support frames for moderate loads. M Clip: Attaches molded or pultruded panels to supports using two adjacent bearing bars; commonly used for stair treads and standard grating panels. C Clip: Connects two adjacent panels of molded FRP grating.

J Clip: Holds a single grating load bar to a support using one bearing bar. G Clip: Attaches grating to structural member flanges, often used when top access is limited. F Clip: Joins factory edges of adjacent abutting panels.

Insert and Saddle Clips: For pultruded grating, Insert Clips slide between bearing bars, while Saddle Clips straddle the top of adjacent bars for higher load applications.

Installation and Hardware

Clips are typically sold as sets including the clip, bolt, nut, and washers, though some specialty clips may require separate bolts. Maximum recommended clip spacing is generally 48 inches on center, with at least four clips per grating piece. Fastener selection depends on the substrate material (steel, concrete, or wood) and project requirements.

ApplicationsFRP grating clips are widely used in industrial platforms, walkways, stair treads, chemical plants, marine environments, and other areas requiring corrosion-resistant, durable grating installation. Specialty clips like G-Clips are used when side-mount fastening is necessary due to structural or design constraints.

Summary

Fiber optic or FRP grating clips are essential for secure, durable, and corrosion-resistant installation of fiberglass grating panels. Selecting the correct clip type, material, and installation method ensures structural stability, safety, and longevity of the grating system.
