Steel Plate Beam Guardrail and End Anchorages

Steel Plate Beam Guardrail End Anchorages are concrete anchoring systems for the end of steel plate beam guardrails. They are usually used in areas with higher than normal traffic volumes or steep road grades, and the design helps prevent vehicles from crossing over the guardrail. Compared to traditional beam guardrail, Steel Plate Beam guardrail end anchorages offer greater strength, durability and protection for vehicles. They are also effective at controlling guardrail deflection and are better suited for use on uneven terrain or in areas with large amounts of runoff.

We supply complete system of guard rails for USA market: Steel plate beam guardrail, posts, end treatments, strut anchorages, radius pieces, & nuts & bolts.

Steel Plate Beam Guard Rail Materials

Steel plate beam guardrail, terminal section, rail splice, splice bolt shapes and dimensions shall comform to AASHTO M 180.
All guardrail shall be class A (12 gauge).
Steel posts shall be ASSHTO M 270m (ASTM A 709) grade 36 steel. After all the holes are punched and cuts are made, posts shall be zinc (hot-dip galvanized) coated according to AASHTO M 111(ASTM A 123).

Installation with steel posts:

Guardrail installed on curves with radius of 150 ft. or less. Rail elements curved. Use the same type of post throughout.

When rail sections used for an installation are 12' 16" long, center the 8 splice bolts on top of each other (or 1/2 apart and 1/2 closed ).

When 25 ft. long rail sections are used for an installation, set the 8 splice bolts according to the air temperature as follows:

Below 10° F., set 3/4 of the splices apart and 1/4 closed.

10° F. to 95° F, set 1/4 of the splices apart and 3/4 closed.

Guardrail, posts, end treatments, strut anchorages, radius pieces, & nuts & bolts.

Long rail and short rail splices, in installation:

W6x9 Steel Post and Spacer Blocks

Notes:
The strut anchorage assembly must include all of the compatible parts of the terminal. Cable release bracket assembly. Bct cable anchor assembly, the ground strut and posts the are attached to. This will assure the proper function of the terminal anchorage. The bolts shall pass through the rail on the last two posts. Do not min parts between systems.
