General technical information
Material: pipes and sections are cold shaped from easily weldable alloy and fine-grain structural steel suitable for hot dip galvanizing.
Surface: the condition of pipe and section materials is after hot rolling and cold processing.
Surface protection: pipe and section surfaces are protected from corrosion due to humidity with an oil emulsion after cold shaping.
Quality check:the production process always includes pre- and post-production quality checks. The pre-production check includes a weight check, a dimension check, a visual inspection of the surface of the source material, and a check that the accompanying documentation is complete. The post-production check includes a dimension check, including shape and straightness, weight, packaging, and labelling. Welds are tested using an expansion test. Tensile test per ČSN EN ISO 6892-1. Declaration of performance (for download), Certificate of conformity of the factory production control (for download).
Packaging: SSC Ostrava has a standard packaging method that ensures sufficient protection during handling and shipping (strapping and clips). Pipes and sections are bound with steel strapping into 1000-2000 kg bundles.
Testing and inspection documents: we issue product certification 2.2 per ČSN EN 10204.
