A554 Tubes

A554 stainless steel tubes are welded tubes made for architectural decoration and structural use. We offer round, square, rectangular, and oval shapes to suit different project needs.
Material options include 304, 304L, 316, and 316L stainless steel grades. Surface finishes are available in a wide range, including brushed (#4), mirror (#8), sandblasted, anti-fingerprint coating, and colored stainless steel.
A554 tubes are known for high dimensional accuracy, consistent surface quality, and stable performance from batch to batch. They are widely used in stair handrails, railings, furniture frames and public space fixtures.

A270 Tubes

Stainless steel A270 tubes are designed for sanitary applications. They are mainly round tubes. We follow ASTM A270 standards strictly, with higher requirements for dimensional accuracy, surface quality, and cleanliness.
Material options include 304, 304L, 316, and 316L grades. In terms of production, we can polish both the inner and outer surfaces. The inner wall is smooth with no dead spots.
A270 tubes are widely used in the food and beverage industry and the pharmaceutical industry. They are also the first choice for dairy processing, brewing, and drinking water treatment, where pipe cleanliness is critical.

Production Capability & Quality Control

We have strong production facilities and a strict quality control system. Every step is documented and meets clear standards, from raw material inspection to final shipment.
Production Scale
We operate 60 continuous forming production lines. This supports large volume orders with stable and reliable output.
Our Capabilities
Production Process
We use fully automatic high-frequency water-cooled welding with nitrogen gas protection. This ensures 100% bendability. All tooling is made from Cr12MoV steel and heat-hardened at high temperature. This keeps dimensions accurate and surfaces clean and smooth.
Our Capabilities
Quality Testing
We use a spectrometer to check the chemical composition of raw materials. A multi-function testing machine runs flaring, indentation, and flanging tests. A roughness tester checks the surface finish of our tubes.
