A rebar coupler must withstand at least ۱.۲۵ times the rebar’s yield stress. A counterfeit coupler that fails to reach this figure poses a serious structural risk.
The weight of each meter of coil and wire rod is obtained using the same rebar formula: diameter squared divided by ۱۶۲. We will become familiar with the formula, the weight table for commonly used sizes, and the method for checking coil weight.
The roll mark between the rebar ribs shows the factory code and production process code and is the fastest way to verify the authenticity of a shipment. You will learn how to read these codes.
In wire rod and coil, the most important signs of quality are diameter uniformity throughout the coil and tensile strength, not appearance alone. Read how to identify a low-quality coil.
A higher grade is not always the right choice for earthquake-prone projects. We examine the differences between A2, A3, and A4 and the A4 limitation in special moment frames from a sales perspective.
