You’ve got a solar array or pipe run that needs clamping, and most off-the-shelf options either corrode or can’t handle the load—we’ve seen installers swap out galvanized steel clamps after six months because rust compromised grip.

These F clamps are machined form 6063-T5 aluminum with a plain finish, covering lengths from 100 to 300mm in M8, M10, or M12 bolt sizes, and the bolt itself is stainless steel (304 or 316, depending on your spec).

They’re heavy-duty clamping on solar panels, pipes, and glass, but don’t use them for loads or moving joints—the F structure gives a rigid hold, not a pivot point, so it’s really for static installations like roof rails or greenhouse framing.


40 kN or so of clamping force is typical for the M12 version, and we’ve tested them up to 500 Nm on the torque wrench without the alumnum galling—just keep the bolt threads lubricated if you’re in a marine enviornment.

our company can do OEM or ODM on these—logo embossing, anodized finishes instead of plain, or custom lengths in the 100–300mm range—but MOQ is usually 500 pieces for nonstandard specs (check lead time on that).

Standard packaging is 20-25 kg per carton, 900 kg per pallet, and delivrey runs 7 to 30 days depending on whether we’ve got stock or need to push a batch through extrusion—most common sizes ship in 2 weeks or so.
We offer the clamp in lengths ranging from 100mm to 300mm, so you can pick the size that fits your specific solar panel, pipe, or glass setup.
We primarily supply it in a plain finish, but we can customize with other finishes like anodizing or powder coating if you need extra corrosion resistance or a specific look.
Our MOQ is typically 100 pieces for standard sizes, but we can negotiate lower quantities for first-time orders or samples—just let us know your needs.
Yes, we can provide certifications such as DIN, ASTM/ASME, JIS, EN, ISO, or GB upon request, depending on the standard you need for your project.
We pack 20-25kg per carton and then stack them on 900kg pallets for safe transport, with delivery typically taking 7 to 30 days based on your order size.
