Pipe Clamps
Pipe clamps offered in this section are designed for support and attachment of pipe to structural
members. A wide range of pipe clamps are available for various applications.
Materials
Carbon Steel is used in the manufacturing of riser and pipe clamps. Stainless Steel and other materials
are available.
Finishes
The standard finishes for mechanical supports are plain steel (oil coated) sometimes referred to as black
and Electro-Plated Zinc (ASTM B 633 SC3). Hot-Dip Galvanized After Fabrication (ASTM A 123), Red Primer,
Plastic Coating, Dura-Green® and other special coatings are available upon request.
Note: Due to the design of some products, (threads, connecting hardware, swivels, etc.) items may
or may not be uniformly coated with special finishes. In some cases, the hanger itself may be coated,
however, the hardware may be supplied Electro-Plated, Copper Plated, or in Stainless Steel.
