Surface Texture

Grids of fiberglass grating can be ordered with or without an anti-skid grit surface. A variety of grit material and textures can be ordered, including fine, medium and coarse.

 

Dimensions

Complete load tables and properties can be provided. Visit the individual pages for each FRP Grating product for load tables, or email or call for info. Bearing bars are assembled into 12 panel sizes; 3', 4' and 5' widths and 8', 10', 12' and 20' lengths. Standard FRP Grating panels come with cross-rod spacings of 6" or optional 12" on center.

 

FRP Grate Panels can be made to exact sizes to eliminate waste and fabrication costs in the field. The maximum panel weight is 500 lbs. and the maximum panel size is 60" x 240".

 

 

 

Panel Hold Downs

FRP Grating panel hold downs are used to keep grating panels stationary. There are three types of grating clip for fiberglass grating.

	Saddle Clips Weldable 316L stainless steel saddle clips are available for all grating series except T-1800 and T-3500. *Bolts are priced separately from the saddle clips.
	Insert Clips Weldable 316L stainless steel insert clips are available for all grating series except T-1800 and T-3500. *Bolts are priced separately from the hold-down.
	Insert Clips for T-1800 and T-3500 Weldable 316L stainless steel insert clips are available for series T-1800 and T-3500 only. *Bolts are priced separately from the hold-down. (All bolts are 1/4-20 x 1-1/4", cap head, 316L stainless steel.)

 

 

Panel Connectors

FRP Grating Panel Connectors are generally only used at midspan to assist in transferring load from section to section.There are three types of panel connector grating clips for fiberglass grating.

	Saddle Clips 316L stainless steel saddle clips are available as panel connectors for "I" and "HD" bar grating and T-bar grating except T-1800 and T-3500.
	Insert Clip Hold-Downs Insert clip hold-downs are available for I-bar grating and T-bar grating except for T-1800 and T-3500.
	Insert Clip Hold-Downs for T-1800 and T-3500 Insert clip hold-downs are available for T-1800 and T-3500 grating. (All bolts are 1/4-20 x 1-1/4", cap head, 316L stainless steel.)

 

 

Curb Angle

Fiberglass Curb Angle provides a strong, firm base for bearing bars and is pultruded from the same material and in the same manner as other DURADEK® and DURAGRID® products. Corrosion resistant Fiberglass Curb Angles are available in four sizes in gray fire retardant vinyl ester.
