68G1 Grooved rail
Product Overview
68G1 (70G) Rail is a heavy grooved (girder) rail profile intended for embedded track where a large, robust section is required — for example industrial tramways, heavy tram/light-rail junctions and short-radius track embedded in paved surfaces. It combines a deep web and broad section stiffness with a grooved head so the running surface can be flush with the roadway while retaining strong structural capacity.

Material Properties
Typical uses & strengths
- Industrial & heavy urban embedded track: deep section and large inertia make 68G1 suitable where embedded track must carry heavier axle loads or larger concentrated loads (industrial terminals, freight-connected tram spurs).
- Junctions, crossings and tight-radius transitions: grooved head keeps the running surface flush with paving while the robust section resists the higher bending and fatigue demands at switches and crossings.
- Longer life under wear/RCF risk: when paired with wear-resistant or head-treated steel grades, 68G1 can offer extended in-service life in abrasive or high-traffic environments.
Welding, installation & maintenance guidance
FAQs
Q :How should embedded 68G1 be installed to avoid premature failure?
A :Pay close attention to groove fillers, drainage, bedding and compaction. Preventing water and debris accumulation in the groove is critical — poor drainage and settlement are common failure initiators for embedded rails.
Q : What information should I include in an RFQ?
A :At minimum: profile name (68G1 and any mill equivalent), quantity (m or t), preferred steel grade/delivery condition, tolerance group, bar length or welded string requirement, any pre-drilling/machining, and delivery location/inspection requirements.
Q:Can 68G1 be welded and repaired in the field?
A: Yes — standard field repair methods (aluminothermic/thermite welding, specialist surfacing) are used. Welding procedures must be qualified for grooved geometry and the chosen steel grade.
