Carbon Steel Grating Clamp

Carbon steel grating clips with hot-dip galvanized finish provide a reliable, lower-cost fastening option for FRP grating in indoor or covered installations where direct salt or chemical spray is not a factor. The zinc coating gives solid corrosion protection for standard industrial environments.

A galvanized grating fastener—often referred to on site as a grating clamp—earns its place on the bill of materials when the environment is dry, the budget is tight, and the fastener count runs into the thousands. The hot-dip galvanizing process deposits a zinc layer typically 55–85 µm thick that metallurgically bonds to the carbon steel substrate. That coating provides sacrificial protection: if the surface is scratched, the surrounding zinc corrodes preferentially, keeping the underlying steel intact. For a warehouse mezzanine or an indoor assembly platform, this level of protection is exactly what the application demands, and the cost saving relative to stainless grades can be substantial when multiplied across an entire grating field.

Mechanically, these steel grating hardware clamps follow the same saddle design as their stainless counterparts. The saddle spans the intersection of two bearing bars, and two M8 or M10 bolts draw it down, transferring the clamping load through the clip body. Installation torque runs 15–25 N·m, and the connection is fully demountable for panel removal during maintenance turnarounds. The hot dip galvanized grating clamp is equally at home securing molded or pultruded panels, and the saddle thickness—typically 2.5–3.0 mm—provides a bearing surface that does not deform under the installation torque. For indoor process buildings, vehicle assembly areas, and covered loading docks, the galvanized clip keeps the grating securely fastened without the premium attached to stainless alloys.

Clamp Specifications & Material Data

Each clamp is supplied as a complete set with saddle, two bolts, flat washers, and lock washers. Packaging is labelled by batch for traceability. These fasteners integrate into the accessories and hardware family alongside stainless steel clips and FRP bolting kits, providing a single source for all grating attachment hardware across the full corrosion-severity spectrum. For outdoor or chemically exposed installations, the 316 stainless clip provides the higher corrosion resistance required—see the platform systems section for guidance on material selection by environment.
