Question: Why is my metal gate sagging, scraping the floor or putting strain on the autogate motor?
Answer: A metal gate usually sags because the hinges or hinge pins are worn, welds have cracked, the pillar bracket has moved, or the gate has been forced while obstructed. Repair may involve re-welding, replacing hinge pins/bearings, shimming the pillar bracket, or realigning the gate. Severe rust or twisted frames may need new hinges or metalwork.

Signs of Hinge Wear
- The gate scrapes the ground when opening or closing.
- There is play when you lift the gate leaf.
- The autogate motor struggles or stops before the gate closes.
- The lock no longer lines up with the strike.
- Welds around the hinge plate are cracked.
- The gate makes a grinding or squealing noise.
Common Causes
| Cause | What happens | Repair approach |
|---|---|---|
| Worn hinge pin/bushing | Gate drops and tilts | Replace pin/bushing |
| Cracked weld | Hinge plate moves | Re-weld or reinforce |
| Loose pillar bolts | Whole hinge shifts | Re-anchor or weld |
| Bent gate frame | Leaf no longer square | Straighten or fabricate |
| Rusted metal | Material loses strength | Cut out and replace section |
| Track/roller fault | Sliding gate binds | Align track/roller |
Why It Should Be Fixed Early
A sagging gate does not only scrape the floor. It puts extra load on the autogate motor, wears the lock and striker, enlarges bolt holes, and can crack the pillar bracket. A motor replacement costs far more than hinge maintenance. The published autogate motor replacement and service starts at RM 950.
What a Metalwork Inspection Covers
- Lift each gate leaf to check hinge play.
- Inspect hinge pins, bushes, bearings and welds.
- Check pillar anchors and brickwork.
- Measure whether the frame is square.
- Test the gate manually before testing the motor.
- Recommend re-welding, hinge replacement or realignment.
KL Servis Rumah offers welding and metal fabrication from RM 280 and on-site welding repair. The published problem range for loose metal gate hinges is RM 250 to RM 1,200+ depending on gate size and whether welding, new hinges or realignment are needed.
Repair vs New Hinges
Repair is enough when the frame is solid and the issue is a worn pin, loose bolt or cracked weld.
Replacement is better when hinges are badly rusted, the frame is twisted, repeated welds have failed, or the gate no longer aligns with the motor and lock.
Safety Note
Do not keep operating an autogate if the metal leaf is visibly dropped or binding. Switch to manual mode and keep children away until the gate is repaired.
Frequently Asked Questions
Can a sagging gate be fixed without replacing it?
Often yes. Worn pins, loose bolts and cracked welds can be repaired if the frame and pillars are still sound.
Why does my autogate stop halfway?
The motor may be detecting extra resistance from a sagging gate, obstruction or track issue. Do not keep forcing it.
How much does gate hinge repair cost?
The published problem range is RM 250 to RM 1,200+, depending on gate size and the work required.
