W-clips were specially developed for fastening HLU panels (sealed/closed gratings) to the support profile. Both the sealed panel and the profile must be drilled. As standard, the W-clip consists of the following parts:
- 1x bolt M8 x 70/90 with countersunk head;
- 1x flat plate;
- 1x arm;
- 1x M8 square nut.
The W-clip is available in a variety of qualities depending on the application and environment.
- Stainless steel 316-A4: Vinylester gratings (type VE-FR, VE-XFR) for chemicals;
- Stainless steel 304-A2: Isophthalic grating (type ISO-FR and all other types) for normal corrosion-resistant outdoors and offshore-marine environments;
- Galvanised (HD): orthophthalic gratings (type ECO-NFR, ECO-FR) for all low-corrosion environments.
Fiberstruct’s fastening materials satisfy all applicable standards. You can find these in the appendices at the bottom of this page.
