How we knowDispatched March and April 2026. Gaps and systems are taken from the production and dispatch records for this job, not from a catalogue. Section drawings are illustrations, not shop drawings.
What this building needed
A 50 mm gap on a station, which surprises people
Station buildings are long, but they are also broken into structurally independent bays, and a short bay in Zone III with a moderate thermal swing does not need a wide joint. Gap width follows the calculation, not the prestige of the building.
MegAtec 610 on the roof
The 610 is our roof joint: an external centre-plate system for roof-to-roof and roof-to-wall junctions, with the plate cut from sheet rather than extruded. Up there the deciding property is water, not traffic. The joint sits under sun and monsoon all year, so the moisture barrier beneath the cover, and how it is finished at the ends of the run, matter as much as the movement rating.
Part of the RLDA station redevelopment programme
Chennai Egmore, Chandigarh, Tirupati, Kollam and Ajni Nagpur. Five stations, four different states, one profile family — which is what an approved specification is supposed to achieve.
