difference between hot rolled tie rod and cold rolled tie rod

What is the difference of hot rolled tie rod vs cold rolled tie rod?

When selecting structural tie rods for infrastructure and construction projects, material quality, manufacturing process and mechanical performance directly influence long term structural safety, construction reliability and overall project economy.

Here is a professional comparison between D15 hot rolled tie rod and 45# cold rolled tie rod.

Item	D15 Hot Rolled Tie Rod	45# Cold Rolled Tie Rod
Material & Manufacturing Process	Highstrength lowalloy steel, processed by hightemperature hot rolling	Ordinary 45# carbon steel, formed by normal cold rolling
Tensile Performance	Superior tensile strength, ultimate breaking load 180–190 kN	Moderate tensile strength, ultimate breaking load 120–150 kN
Thread type	Full continuous standard thread with stable mechanical transmission, no ribbed	Ordinary full thread for basic connection only
Core Advantages	High prestress tension capacity, antiburst, antifatigue, reusable onsite	Costeffective, easy machining, stable supply and fast delivery
Limitations	Relatively higher unit price, nonweldable design	Risk of thread slipping and brittle fracture under heavy loads
Typical Applications	Heavyload highformwork support, bridge engineering, deep foundation pits, Anchoring in rock or concrete	Civil residential buildings, general formwork fixing and lightduty construction
