The materials that are normally used to make the clamp body are polypropylene (PP), polyamide (PA) and aluminium (AL). Generally, polypropylene is green, polyamide is black, and aluminium is silver in color. The different colors help to differentiate the material that is being used. The PP clamp body however, can also be made in other materials upon request. As for the cover plate, single weld plate and hexagon head bolts; they are usually in either steel or stainless steel.
