Our Q235B ERW black steel pipe shipped to Malaysia last week has arrived at the destination port after a 12-day transit. The steel pipes were shipped in four 40HQ containers.
Client Background
The client is a Malaysian structural engineering company and a large-scale professional supplier of steel structures and municipal infrastructure materials.
The Q235B straight seam welded steel pipes purchased by the client are mainly used for a steel frame structure project in an industrial park in Kuala Lumpur.
We provided full-process services for this project, including inquiry handling, technical parameter confirmation, customized production, quality inspection, container loading, customs clearance and inspection, sea freight, and final delivery.

Production & Quality Control
Our professional QC department implemented full-process quality control for this batch of Q235B straight seam welded steel pipes, completely avoiding quality problems such as welding defects, dimensional deviations, and substandard corrosion resistance.
Strict incoming inspection is carried out on raw materials, including the chemical composition and mechanical properties of hot-rolled steel strips, ensuring that yield strength, tensile strength, and low-temperature impact toughness meet standards.
Production employs high-precision ERW resistance welding technology, resulting in a single weld with a smooth, flat surface free of cracks and incomplete welds.
Quality Inspection
All steel pipe welds undergo online non-destructive testing (NDT) to ensure weld sealing and structural stability meet standards.
Standardized length cutting and deburring of pipe ends facilitate customer welding and installation.
Logistics, Export & Delivery Process
This project adopts a factory-to-ship shipping model, ensuring standardized export and timely delivery to the destination port.
Steel pipes are grouped and bundled with steel straps. All container loading operations are supervised by dedicated personnel throughout the process, with reasonable planning of cargo placement to ensure stable stacking and even stress distribution.
Shipment Details
The goods are loaded onto a ship at Tianjin Port and shipped directly to Port Klang, Malaysia.
Upon arrival at the port, our company assists the client in preparing customs clearance documents and guides customs clearance, delivery, and collection at the destination port.
Project Outcome & Client Feedback
This batch of Q235B straight seam welded steel pipes was successfully delivered to our Malaysian customer and passed on-site project acceptance on the first attempt.
The customer highly praised the product quality: the steel pipes were of precise and uniform specifications, with stable material properties and excellent weld quality, meeting their construction needs.
We provide a stable supply of Q235B ERW welded pipes to global customers, along with mature ocean freight export services.
