Welded Steel Pipes & Hollow Sections

STREETWISE / PROCUREMENT GUIDE

Product & procurement guidance

Pipe and hollow-section categories

Circular hollow sections / round welded pipes: often considered for frames, fabricated assemblies and general industrial work, depending on grade and specification. Square hollow sections (SHS): commonly used in frames, supports and fabricated structures. Rectangular hollow sections (RHS): useful where a rectangular profile fits the design or fabrication requirements. The listed forms are standard industry categories; available StreetWise sizes, grades and manufacturing routes must be checked before publishing a product table.

Key information for welded steel pipe enquiries

State the outer diameter or width and height, wall thickness, material grade, length, quantity, finish, applicable standard and destination. If the pipes are for pressure service, structural load-bearing use or another regulated application, specify the governing standard and certification requirements: a generic welded pipe description is not evidence of suitability.

From specification to supply

Before comparing quotes, ensure all suppliers are pricing the same grade, nominal dimensions, finish, lengths, inspection scope and documentation. Drawings or a clearly labelled bill of materials help reduce ambiguity, especially when multiple section sizes are involved.

Welded pipes FAQ

What is the difference between SHS and RHS? SHS has a square hollow cross-section, while RHS has a rectangular hollow cross-section. The suitable section depends on the project design, fabrication method and required structural performance.

What details are needed for a welded pipe quote? Provide cross-section shape, dimensions, wall thickness, grade, length, finish, quantity, applicable standard and delivery destination.

Are all welded pipes suitable for pressure applications? No. Suitability depends on the specific grade, applicable production and testing standard, and intended service. Confirm all engineering and compliance requirements before ordering.
