Step 1: Assemble required parts using above table

A flat work area is required. It is very helpful to build a platform or work table to hold the stringers at a height to facilitate welding without the welder bending over or working on his knees. Once a platform is built, it can be marked to ease the layout of stringers and rails.

Step 2: Lay out the channel sides and the stringers

  • The legs of the channels should be pointed inward.
  • Measure from corner to corner to verify the layout is square.
  • From the outside edge of the channel, measure 24” and place the first interior stringer on the center of the 24” measurement.


 Other interior stringers are placed on 24” centers until all stringers and the side channels are aligned.

Step 3: Weld beams

  • Place the center rail section perpendicular to the stringers and weld it to each beam and channel with ¼” welds the full width of the flanges on each side of the rail.
  • Welding with ASW E 60 or 70 series electrodes is recommended.


 It may be helpful to hold the rails in place with clamps while welding. Big R cattleguard rail is cold roll-formed. It is very straight and does not have a twist which is often found in similar rail that is formed on a press brake. The difference will be obvious to the welder. Always specify roll-formed rail to reduce the labor required to finish the cattleguard.

Step 4: Weld rails

Place and weld additional rails on 7 ½” centers. By starting with the center rail and working to the edges of the cattleguard, a welder can stand between the stringers and still be close the area of welding. Prior to welding the two outside rails, proceed to the next step.

Step 5: Close ends

When all the rails, except the outside two, are welded in place close the ends of the cattleguard with the ¼” x 8” plate. This is done by welding the plate to the ends of the stringers and channels. After the end plate is attached, weld the remaining two rails.

Step 6: Finish

Blast clean, prime and finish paint.
