Wherever reinforcement has to be joined at full strength — in tower columns, across bridge decks, or in track slabs built to a programme.
Column, core and shear-wall bars are heaviest exactly where they have to be joined. A threaded splice transfers the full bar inside one sleeve, so the cage stays open enough to place and vibrate concrete, and the column keeps its designed section at every floor.
Piers, pier caps and deck slabs are poured in stages that can stand for weeks. The coupler leaves a finished thread at each construction joint, capped and clean, so the next pour connects at full bar strength instead of a lap the designer has to find room for.
Viaducts, track slabs and station boxes run to a fixed programme with the project authority checking every splice. Every size from 12 to 40 mm is rated for Type 2 seismic performance, with documented test reports so a joint can be signed off on the day it is made.
A tower column, a bridge deck and a track slab ask the same thing of a joint: carry the full bar where a lap cannot reach. RebarConnect makes the parallel thread, the coupler and the protection cap in-house, across eight sizes from 12 to 40 mm — so the splice on your drawing is the splice that arrives on site.
