Rungcharoensap Service & Supply Limited Partnership offers carbon steel grades S235, S355 and Q355 for structural and industrial applications, with outer diameters spanning 21mm to 3000mm. The inventory includes heavy-wall seamless and welded carbon steel pipes designed for building frameworks, support structures and fluid transportation systems.
These non-alloy structural steels conform to standard European and Chinese designations, with S355 and Q355 providing higher yield strength typical for load-bearing construction. Typical tensile strength for S355 is 470-630 MPa, while Q355 offers similar mechanical properties under Chinese GB standards. The material is supplied as black steel, with surface condition and dimensional tolerances aligned to standard mill certifications for structural pipe.
Contractors and importers use these pipes for infrastructure projects, mechanical engineering and industrial plants where reliability under static and dynamic loads is critical. DDP and FOB trade terms are available, with packaging and bundling configured for containerised shipment. Buyers confirm exact lengths, wall thickness and coating requirements with the supplier, as these are project-specific and not standardised across all stock.

Before ordering, verify the exact grade, dimensions and manufacturing method of the steel pipes, as these directly impact structural integrity. Request mill test certificates and third-party inspection reports to confirm chemical composition, mechanical properties and compliance with international standards such as EN 10025 for S355 or GB/T 1591 for Q355.
Logistics details to confirm include container type (20ft or 40ft), bundling weight limits and port of loading in Thailand. Incoterms such as FOB or DDP should be clarified, including who bears the cost of duties, taxes and inland transportation. Payment terms, such as TT (Telegraphic Transfer) or LC (Letter of Credit), must also be agreed upon in advance.
Quality checks should cover dimensional accuracy, surface defects and mechanical properties. Inspect a sample batch for outer diameter, wall thickness and straightness using calipers and straightedges. For critical applications, conduct non-destructive testing (NDT) such as ultrasonic testing for internal flaws. Ensure all documentation, including packing lists, invoices and certificates of origin, is complete for customs clearance.
