ASTM A554 TP304 stainless steel welded square tubing is a high-strength, austenitic, corrosion-resistant mechanical tubing designed for structural and decorative applications.
GNEE is a leading manufacturer and supplier of stainless steel square tubing products, offering a wide range of specifications and sizes. Dimensions conform to ASTM, ASME, and API standards. 304 stainless steel is the most commonly used grade. Therefore, ASTM A554 Mt304 grade stainless steel tubing is the most widely used stainless steel tubing.
ASTM A554 Mt304 stainless steel rectangular tubing offers high strength and resistance to mild corrosion. It has a minimum yield strength of 205 MPa, a minimum tensile strength of 515 MPa, and an operating temperature of 870 degrees Celsius. It features excellent durability, weldability, and is available with typical rolled or polished surface finishes. This versatile, non-magnetic, and cost-effective tubing is widely used in construction, exhaust systems, furniture manufacturing, and food processing, among other applications.

GNEE factory specializes in the production of ASTM A554 TP304 stainless steel welded square tubes, boasting years of experience in stainless steel pipe manufacturing and a comprehensive quality management system. The factory is equipped with advanced automated welding production lines (with an annual capacity of over [number] tons). All raw materials are sourced from first-tier steel mills (such as POSCO, BaoSteel, and TISCO), and the chemical composition and mechanical properties are strictly controlled according to ASTM A554 / TP304 standards, ensuring industry-leading corrosion resistance, weldability, and dimensional consistency. Our welds undergo 100% automatic non-destructive testing (such as eddy current/radiographic testing), significantly reducing the risk of internal defects and improving product reliability.
In terms of packaging and transportation, we provide multi-layer protection solutions based on customer needs:
Inner layer anti-rust paper + stretch wrap film to effectively prevent moisture intrusion;
Outer layer wooden pallet fixing + heat shrink film to enhance transportation stability;
Rolled or supported packaging can withstand a maximum load pressure of 800kg, suitable for multimodal transportation by sea, rail, and road.
All shipped pipes are accompanied by a factory inspection certificate (MTC), dimension report, and packing list for easy customs clearance and on-site acceptance.
To keep customers informed of the status of their goods, we provide full-process logistics tracking services:
Production phase tracking: Real-time inspection data for each batch of products is uploaded to the customer's shared system (including dimensions, chemical analysis, and weld flaw detection results).
Pre-shipment photo/video confirmation: Including packaging details, pallet number, container seal number, etc.
Transportation phase logistics tracking: Integrated with our partner logistics platform, allowing real-time location and ETA (estimated time of arrival) tracking via shipment number.
Anomaly warning mechanism: In case of delays, customs clearance issues, or transportation anomalies, we will notify you within 2 hours and provide solutions.
