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/Z Bar
| 45# Cold-Rolled Tie Rod
|
Material & Manufacturing Process
| High-strength low-alloy steel, processed by high-temperature 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, anti-burst, anti-fatigue, reusable on-site | Cost-effective, easy machining, stable supply and fast delivery |
Limitations
| Relatively higher unit price, non-weldable design | Risk of thread slipping and brittle fracture under heavy loads |
Typical Applications
| Heavy-oad high-formwork support, bridge engineering, deep foundation pits, Anchoring in rock or concrete | Civil residential buildings, general formwork fixing and light-duty construction |
