Guardrail posts carry the beam and transfer crash load into the ground. Getting the post section, spacing and embedment right is what makes a barrier redirect a vehicle instead of simply folding over. SinoBarrier supplies every common post profile — I-beam, C-channel, sigma, round, square and U-shape — hot-dip galvanized and drilled or punched to your drawing.
Post profiles we supply
| Profile | Typical use |
|---|---|
| I-beam post | Standard for W-beam and thrie-beam runs |
| C-channel post | Light-duty and municipal installations |
| Sigma post | Common in European and export specifications |
| Round post | Standard for many Asian and Middle Eastern projects |
| Square post | Perimeter and light-duty barriers |
| U-shape post | Bracket-mounted and retrofit applications |
What we control on every post
- Material — Q235B or S355JR steel, hot-dip galvanized to AASHTO M180.
- Length and embedment — cut to the depth your soil and foundation design call for.
- Hole pattern — bolt holes and slots punched to match the beam and spacer.
- Finish — hot-dip galvanized; PVC-coated or painted options on request.
Send the drawing or bill of quantities and we return a post schedule with section, length, spacing and embedment for every run.
