Finish your project with the right Fiberglass Grating Clips

National Grating has stainless steel hold-down clips and fasteners for all types of fiberglass grating. We also carry the matching nuts, bolts and washers – all the fastener hardware you require for easy installation of your FRP grating clips.

S.S. Hold-down clips and fasteners for FRP grating are corrosion resistant, durable and economical.

Molded Fiberglass Grating Clips

For Molded Grating with a 1-1/2″ square mesh grid pattern, we recommend Stainless Steel M-Clips.

Molded Grading M-Clips

Molded Grading M-Clips

S.S. M-Clips Straddle the 1.5″ square openings on molded square mesh grating. They drop down 1/2″ to a mini-platform with a 1/4″ hole.

To through-bolt the M-Clips to a support underneath, we can supply a 1-1/2″ or 2″ hex-head bolt assembly. You can also use wood-screws, self-tapping screws, or Hilti fasteners available at your local building supply outlet.

Molded Grating M-Clips can be used to fasten down both 1″ deep and 1-1/2″ deep molded grating. The M-Clip clip is 1/2″ deep allowing easy access to the bolt-head. For 2″ molded grating we recommend Saddle Clips (See below).

Pultruted Fiberglass Grating Clips

For Pultruded Grating, we offer both Insert Clips or Saddle Clips.

I-6000 Insert and Saddle Clips

I-6000 Insert and Saddle Clips

Insert Clips (Left)  slide in between the bearing bars and are supported by the lip at the bottom of the I-Beam or T-Beam.
Insert Clips do not affect the surface of the grating, which is important for applications such as fiberglass pool grating.

Saddle Clips (Right) straddle over the top adjacent bearing bars. They are stronger than insert clips and can be easily dropped in between bearing bars.

One of the specialty clips we sell are called G-Clips. Whereas M-clips, Insert Clips and Saddle Clips are used to through-bolt directly above an underlying support, G-Clips are used to attach to a support from the side.

In today’s connected world, we depend on cellular telephone signals, Wi-Fi networks and over the air radio and television signals. Wi-Fi and Bluetooth connectivity are essential to on-site work environments. Steel structures significantly disrupt these signals. Fiberglass structures and grating are an essential part of FRP building structures that are “electronically transparent” and do not interfere with radio frequency transmissions.
