HIGHWAY GUARDRAIL PRODUCTS
GSI carries an extensive inventory of highway guardrail products including 10 gauge and 12 gauge material. We stock curved guardrail from 5' to 60' radii, a wide variety of terminal end conditions including SGTs, and a wide variety of steel and timber posts for state and non-state use.
GSI is a TxDOT-approved warehouse for guardrail and posts. We also sell guardrail to many other states around the country, offering competitive pricing with LTL and/or truckload quantities.

Maryland Guidelines of Traffic Barrier Placement & End Treatment Design
Need help with a takeoff or placing an order?
It is important we know the following to ensure you get the product you need the first time:
-
Is this a state or non-state job (state-tested inventory cannot be shipped non-state jobs).
-
If it is a state job, what is the project information?
-
How many runs are there?
-
Is the rail blocked out?
-
Do you need radiused rail? How many curves? Length? Radius of each?
-
Steel or timber posts?
-
Are there low-fill culverts that will require base-plated posts? How thick is the culvert "top"?
-
What end treatments do you need? TAS?, FEW?, SGT Type I, II, or III?
-
To what type of concrete railing are we attaching the transitions?
Concave: Bowing away from the traffic lane
Convex: Bowing towards the traffic lane
To find the Radius for a curved rail:
-
Step 1: Starting at the last post in the straight run (point A), lay
cloth tape along the path that the curved guide rail will follow. -
Step 2: Mark-off two points along the curved cloth tape: one at 6'-3", (point B) and the second at 12'-6" (point C).
-
Step 3: Pull string directly from starting point (point A) to the second mark-off point (point C).
-
Step 4: Measure from the first marked-off point (point B) over to the mid-point of the taut string. this measurement (D) is the rise or "middle ordinate."
-
Step 5: Check the chart to find the Radius (R), given the Rise (D).
-
Example: a Rise of 3 7/8" inches would result in a Radius of 60 feet.
