Work before shipment
Before the steel pipes are shipped, first of all, we will test the steel pipes, including measuring the outer diameter, wall thickness, length, zinc layer thickness, etc. After testing, steel pipes will be packed, including baling or bulk, using wooden cases or non-woven bags, attaching plastic pipe caps or metal protectors to the ends of steel pipes, and wrapping cotton rope. Finally, the steel pipe is delivered to your designated location by container ship, bulk carrier or rail
Application
JIS G3466 square and rectangular steel pipe are widely used in machinery manufacturing, construction, automobile industry, metallurgy industry, home decoration and other fields. For example: agricultural vehicles, agricultural greenhouses, railway, highway guardrail, container skeleton, door and window decoration, frame, fitness equipment, steel furniture and various brackets, etc..
