Bright Rectangular Steel Pipe

Bright Rectangular Steel Pipe is made of high-quality carbon steel or low-alloy steel, manufactured using cold-drawing or cold-rolling processes, and then subjected to bright annealing and precision straightening.

High Dimensional Accuracy: Precision machining using cold drawing or cold rolling ensures strict control over dimensional tolerances and wall thickness consistency, reducing machining and improving assembly efficiency.

Bright Surface Quality: After bright annealing, the surface is free of obvious oxide scale and rust defects, allowing for direct surface treatments such as spraying, electroplating, and polishing.

Good Machinability: A suitable heat treatment process guarantees strength and toughness, making it suitable for various deep processing techniques such as welding, bending, stamping, and cutting.

Stable Product Consistency: Standardized production and comprehensive quality control ensure consistent dimensions, performance, and surface quality across different batches of products.

Precision Steel Tube Standards: Complies with standards such as EN 10305-5 and DIN 2395, providing steel grades such as E155, E195, E235, E355, ST37, and ST52, suitable for precision machinery and automotive parts.

Structural Steel Tube Standards: Complies with standards such as ASTM A500, EN 10219, JIS G3466, and GB/T 6728, providing steel grades such as Q235B, Q355B, S235JR, and S355J2H, suitable for engineering structures and equipment manufacturing.

Raw Material Inspection: Inspects chemical composition, mechanical properties, and surface quality.

Cold Drawing/Cold Rolling Forming: Improves dimensional accuracy and wall thickness consistency.

Bright Annealing: Eliminates internal stress, improves machinability, and maintains a bright surface.

Straightening and Length Adjustment: Improves straightness and length accuracy.

Finished Product Inspection: Performs dimensional, mechanical property, UT, ET, and other tests.

Packaging and Shipping: Identifies furnace number and uses export-grade rust-proof packaging.

Product Customization: Supports customization of dimensions, length, wall thickness, tolerances, and steel grades.

Processing Customization: Supports cutting, chamfering, beveling, punching, and pipe bending.

OEM Service: Supports inkjet printing, stamping, labeling, and branded packaging.

Packaging Customization: Supports mixed containers, wooden crates, and customer-specified packaging.

Automotive Manufacturing: Used for chassis, structural components, and transmission parts.

Hydraulic Equipment: Used for hydraulic cylinders, pneumatic cylinders, and fluid conveying components.

Precision Machinery: Used for automation equipment and mechanical structural components.

Engineering Structures: Used for steel structures and industrial equipment frames.

Metal Furniture: Used for office furniture, display racks, and fitness equipment.

Export Rust-Proof Packaging: Utilizes VCI rust-proof paper, rust-proof oil, waterproof PVC, and plastic caps.

Safe Transportation: Steel strapping, wooden crates, or pallet packaging, suitable for sea freight export.

Container Loading: Supports 20GP, 40GP, and 40HQ container loading options.
