• Welding: Automatic submerged‑arc welding is applied to the main beam to achieve uniform, deep weld penetration and build a robust structural base. Seasoned welders carry out meticulous supplementary welding for critical joints and complicated frame sections, making sure every weld meets strict quality benchmarks. Such craftsmanship delivers reliable safety and long‑term durability during heavy‑duty operations.
• Surface Coating: We adopt electrophoretic coating procedures. Trailer frames go through degreasing and phosphating pre‑treatment before cathodic electrophoretic dipping, creating a full‑coverage anti‑rust barrier without uncovered gaps. A final top‑coat spray builds a tough abrasion‑resistant outer finish, delivering lasting anti‑corrosion performance and stable visual quality over years of field operation.

• Main Beam: Welded I-beam structure using Q345/T700 high-strength steel ensures excellent structural stability and operational safety.
• Flexible Length Options: Frame lengths can be adjusted between 20‑60ft for better transport efficiency and application compatibility.

• Floor: Thickened checkered steel plate provides excellent anti-slip performance and load capacity.
• Unobstructed Flat‑deck Layout: Barrier‑free open frame enables multi‑angle loading & unloading for bulky machinery and lengthy steel profiles.

• Suspension System: Mechanical and air suspension options provide excellent shock absorption and smooth driving performance.
• Safety Configuration: Rear thickened steel anti-collision beam, high-brightness LED lights, and reflective strips enhance driving safety.
• Twist Locks: Equipped with internationally compatible container twist locks for easy operation and reliable locking, preventing cargo shifting or damage.

• Stakes: Optional removable steel stakes prevent side-slip of goods and improve safety when transporting bulk cargo.

‑ 12‑month warranty takes effect upon goods departure. Manufacturing‑caused failures enjoy free replacement and maintenance service.

‑ Continuous original component supply is offered, alongside practical operation guidance to extend the trailer’s service lifespan.

Q1: Can it transport both containers and bulk cargo?
A: Absolutely. The open flatbed design, combined with container twist locks and adjustable stake systems, allows flexible adaptation to container transport and bulk cargo transport, achieving multi-purpose use with one trailer.
Q2: How is the platform made anti-slip?
A: Raised‑pattern checkered steel plates are adopted for the trailer platform to boost surface friction. When paired with a dedicated cargo fastening system, it keeps goods stable throughout the whole transit process.
Q3: Can the twist locks fit different container sizes?
A: Yes. Position‑adjustable twist‑lock units fit mainstream 20ft and 40ft containers without component swap‑outs and expand overall equipment versatility.
Q4: What if the deck strength is insufficient for heavy engineering equipment?
A: The main beam is structurally optimized to ensure safe load-bearing even under concentrated loads from heavy machinery. Thickened checkered steel plate and increased cross-beam density enhance local load-bearing capacity.
Q5: How long is the delivery time from order to shipment?
A: Standard‑spec units take 20‑25 working days for manufacturing. Projects with special customisations will get individual assessment according to technical specs, followed by a clear production timeline.
