Your Single Source for Cooling Tower Components!

Since the 1960’s, C. E. Shepherd Company has offered an outstanding line of high quality cooling tower components. Shepherd components resist corrosion from extended exposure to water and hostile environmental conditions better than any competitive products. Engineered for retrofit or new construction, Shepherd Cooling Tower Components are easy to install and reduce overall labor costs.

A single source for prompt delivery from stock streamlines purchasing, reduces costs and ensures a fully integrated system thus assuring the same high degree of quality cooling tower professionals have come to expect from C. E. Shepherd Company.

Hanger Grids

Shepherd Fill Slat Hangers are precision welded wire with uniform grid size and superior corrosion resistance. Hangers are available in galvanized, PVC coated or stainless steel mesh. Standard grids are manufactured and stocked in a variety of gauges, straight or racked. Custom grids may be made to order. Time tested Shepherd Fill Slat Hangers deliver longer tower life and virtually eliminate fill support failure.

Hanger Brackets, manufactured from high quality, corrosion resistant polypropylene, are designed to work in concert with Shepherd Fill Slat Hangers to make installation faster, easier and more efficient.

Consider these additional benefits:

• No loss of resin or tensile strength from age or constant exposure to water. Materials don't become brittle with age.

• Greater tensile strength and rigidity simplify handling and installation.

• Self-extinquishing materials virtually eliminate fire hazards.

• Higher load bearing strength.

The Manufacturing Process

The Core WireC. E. Shepherd Company fill slat hangers are manufactured from high quality precision

welded wire mesh. The steel core wire meets or exceeds ASTM Standard A-90 for quality.

Much of the wire mesh we sell has a fuse-bonded PVC coating for superior corrosion

resistance. Standard PVC color is black. Mesh is also available clad in green, red or yellow;

color availability may vary.

GalvanizingWe galvanize our wire BEFORE welding to assure the most uniform coating of zinc possible.

This eliminates the potential for zinc to concentrate at the welds where it is least needed.

Contrary to popular misconception, welded wire is not prone to corrode preferentially at the

welds. In fact, resistance welding of galvanized wire creates a zinc rich iron alloy around the

perimeter of the weld interface. This zinc iron alloy is much more corrosion resistant than the

low carbon steel wire core and provides additional

protection to the weld joint which is already naturally

corrosion resistant (even without the cathodic protection

of the zinc).

Corrosion and Cut EndsIn brief, cut ends of galvanized steel wire do not rust so

long as they are protected by the zinc on the surface of

the wire. The zinc on the periphery of the wire serves in a

sacrificial manner to protect the steel face of the cut end.

Offered as evidence of this are the Twenty Year Report

(ASTM 585 A) and the Thirty Two Year Report (ASTM DS

65) both conducted at State College, PA. The data in

these reports was gathered from observations of cut ends

of four galvanized chain link fence locations. At the end of

twenty years, all fences were found to be 100G (100%

gray metallic). In other words, no rust was present. After thirty two years, three fences were

found to be 100G and the fourth was 70Y (70% of the cut face had a yellow alloy layer of

protection) and 30R (30% of the cut face had rusted).

WeldingOur computer controlled precision welding techniques ensure consistent quality. Welded

mesh offers a number of advantages over conventional twisted mesh:

• Unlike twisted mesh, welded mesh does not move and flex inside its coating.

• Welded wire can be field cut without compromising structural integrity.

• Welded mesh does not unravel.

• In most applications, damaged sections of welded wire mesh can be cut out and replaced

without compromising the integrity of the wire mesh.

Shepherd Wire Mesh Products

The C. E. Shepherd Company produces literally millions of feet of quality wire mesh every

year, for a broad variety of applications. Much of this wire mesh is coated with a durable PVC

coating that is fuse-bonded to the wire in a proprietary process which makes the wire

extremely rust and corrosion resistant. The coating also provides a smooth, snag-free

surface which is easy to clean and requires little

or no maintenance. Products made of C. E.

Shepherd Wire last and will not rust even when

exposed to water or other corrosive

environments over long periods of time, and will

withstand the roughest use you can give them!

Strong and durable, Shepherd Wire provides

economical value by significantly reducing

replacement costs.

Shepherd Wire Mesh is available in a large

assortment of gauges and welded and woven

mesh sizes. These are just a few of the possible

uses for Shepherd Wire Mesh. More specific

information is available; please call for details.

TECHNICAL BULLETIN - Cooling Tower Fill Slat Hanger Specifications

SHEPHERD PERFORMANCE TESTED COOLING TOWER PVC COATED FILL SLAT HANGERS

The wire hangers are manufactured from wire galvanized before welding, with a uniform diameter of not less than 14 gauge. Each hanger to be chemically cleaned and washed prior to coating with PVC. Coating will be factory applied by the fluidized bed process of fuse bonded PVC coating. A film thickness of ten (10) to twenty (20) mils is required. Minimum tensile strength of the galvanized steel fill slat hanger will be not less than 60,000 psi. Minimum tensile strength of the stainless steel slat fill hanger grid will be not less than 90,000 psi. Minimum elongation of the PVC coated will be not less than 200%.

Any cutting in the field will be a minimum of ¼” from any weld. Hanger coating surfaces are compatible with fill batt material to prevent wear to the fill batt. Hangers are shipped precut and flat in protective packing to prevent damage to the coating.




FUSE BONDED PROCESS METHOD

A. METAL PREPARATION - SEVEN STAGE HOT CLEANING AND DEGREASING, PLUS PHOSPHATIZING. THIS METHOD INSURES CLEAN MATERIAL FOR BEST ADHESION BETWEEN WIRE AND COATING.
