Packaging & Shipping

1. All of our stainless steel seamless pipe & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches.
2. For some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation.
3. For enhanced customer experience, we also provide dedicated package as per your special requirements.

Certifications

The inspection of our company and products is open to customers themselves or their designated third-party inspectors, such as SGS, BV, TUV, DNV, etc., who are well-known in the industry.
