How Sepehr Sanat Steela produces EN 1317 and ISIRI 21208 road restraint systems in Isfahan: steel selection, roll forming, hot-dip galvanizing and complete installation kits.
Stage 01
Hot-rolled S235JR and S355JR steel (EN 10025) is cut and roll-formed into W-beams, posts and spacers exactly to each system’s drawing.
Stage 02
Each part is fully immersed in molten zinc, giving a continuous coating that protects the steel for decades of outdoor service.
Stage 03
Every system ships as a kit: W-beams, posts, spacers, bolts, nuts and end pieces packed per project length.
Quality
EN 1317 classifies a road restraint system by its containment level (N2, H1, H2, H4b), working width (W1–W8) and impact severity (A or B). Our systems are crash-tested to it, production runs under an ISO 9001:2015 quality management system, and the Persian Guardrail is produced to Iran’s national standard ISIRI 21208.
