FAQ

1. What is a Heavy-Duty Truck Door Hinge?
A Heavy-Duty Truck Door Hinge is a robust, load-bearing mechanical assembly that connects the cab doors, sleeper box doors, or trailer doors to the vehicle's main body frame. It enables the door to swing open and closed smoothly while supporting its full weight and withstanding constant use, vibration, and road impacts over the vehicle's lifetime.

2. What types of hinges do you manufacture for the trucking industry?
We produce a comprehensive range for all heavy vehicle applications:

Cab Door Hinges: For truck driver and passenger doors.

Sleeper Compartment Hinges: For access to the rear sleeper area.

Trailer Rear Door Hinges (Swing Doors): Heavy-duty, often strap or piano-style hinges.

Trailer Side Door Hinges: For side-access cargo doors.

Hood (Bonnet) Hinges: For engine compartment access.

Battery Box & Storage Compartment Hinges.

Custom Hinges for specialized bodies (refrigerated, dump, tanker trucks).

3. What materials and construction are used?
Our hinges are engineered for maximum strength and durability:

Leaf/Strap: High-Strength Pressed Steel (3mm-8mm thick, grades like SPHC, Q235B) or Forged Steel for extreme duty.

Pivot Pin: Hardened & Ground Steel Pin with a diameter matched to the load (e.g., 16mm, 20mm, 25mm).

Bushings/Bearings: Bronze Oilite Bushings (self-lubricating) or Needle Roller Bearings for smooth, long-lasting operation with minimal maintenance.

Fasteners: Grade 8.8 or 10.9 High-Tensile Bolts.

Finish: Electro-phosphated + E-coated (standard OEM finish), Hot-Dip Galvanized, or Powder Coated.

4. How can I get a quote or technical support?
For the fastest and most accurate service, please provide:

Vehicle/Part information as detailed in Question 4.

Your target price and annual volume forecast (if applicable).

Any special requirements (e.g., bearing type, special coating).

5. What are your payment and shipping terms?
Payment: Standard T/T (30% deposit, 70% before shipment). L/C terms available for established customers.

Shipping: FOB main Chinese ports (Shanghai, Ningbo, Shenzhen) is standard. CIF/DAP to major destinations available upon request.

6. Do your hinges come with bushings or bearings?
Our heavy-duty hinges typically come pre-assembled with durable bushings (bronze or polymer) to ensure proper pin fit and smooth rotation. For ultra-heavy-duty or high-cycle applications, we can manufacture hinges with sealed needle roller bearings upon request. This information is specified in the product details.

7. What is the load capacity and durability?
Our hinges are designed to handle the demanding lifecycle of commercial vehicles:

Static Load: Supports the full weight of the door (which can be over 100 kg/220 lbs for large trailer doors).

Dynamic Load: Withstands forces from door slamming, wind, and road vibration.

Cycle Life: Engineered for tens of thousands of open/close cycles.
We provide specifications based on design and application.

8. How are they installed?
Installation generally requires mechanical skills and proper tools:

Support the door securely (using a jack or helper).

Remove the old hinge by unbolting it from the door and body pillar.

Clean the mounting surfaces.

Position the new hinge and bolt it into place, following the correct torque sequence and specification.

Check door alignment and adjust if necessary.
We recommend professional installation for safety and proper door function.

9. Can you produce custom hinges for body builders or OEMs?
Absolutely. OEM and custom engineering are our core strengths. We work directly with truck manufacturers, trailer builders, and upfitters to:

Design and prototype hinges for new vehicle models or custom bodies.

Meet specific material, coating, and performance specifications.

Provide Just-in-Time (JIT) delivery for assembly lines.

Fully private label the parts.

10. What is your MOQ (Minimum Order Quantity)?
Aftermarket Replacement Hinges: MOQ 50 pairs (100 pieces) per part number.

OEM / Custom Project Hinges: MOQ 500 pieces (negotiable based on program volume).

Samples: Available for fit and function testing.

11. What is your production lead time?
Samples (for existing design): 15-20 working days.

Standard Replacement Parts: 25-35 working days.

New Custom/OEM Program: 45-60 days for tooling and initial samples after design approval.
