Q345B or T700 main beam?
Q345B suits general freight duty. T700 is a higher tensile steel that allows a lighter beam for the same strength, which matters when you are chasing payload.
What kingpin size is fitted?
2 inch or 3.5 inch, matched to your tractor's fifth wheel.
Can the deck be lengthened?
Deck length is set per order. Tell us the length you need and the cargo, and we will confirm feasibility against axle positions.
Do you ship to my country?
SINOHENG exports in bulk to 30+ countries and regions across Southeast Asia, Africa, the Middle East and South America. Send your destination port with the enquiry and we will quote delivery with the trailer.
Ask for a Drawing Before You Commit
We confirm dimensions, axle loads and coupling height on an approval drawing before any steel is cut, so the trailer is legal and couples to your tractors.
