CROWN X TMT bars can be bent and re-bent around very small mandrels of 2D and 4D correspondingly without challenges, which have numeral advantages at construction sites.
The rib and cross rib pattern of CROWN X TMT and Crown Next TMT respectively has been specially designed to ensure that excellent bond strength is developed between the bar and the surrounding concrete. While the specification stipulates that bond strength should be 40% higher than that of mild steel plain bars, Crown-X and Crown Next have the same higher to as much as 90%. This leads to increased safety and durability of the structure even in the most hazardous environments.
