Trade saction - "double-edged sword"

The United State Commerce Department announced yesterday (Sept.7) that the country’s preliminary arbitration judging that the imports of alloy steel plate from China is dumping into local market.

The Commerce Department decided to launch anti-dumping investigation to carbon alloy steel plate from South Korea, France, Japan, Italy, Brazil, and China, at the request of three local steel enterprises.

And on the same day, the Department believed that the relative products from China involve 210.50% anti-subsidy duty, while South Korea has no subsidy.

In 2015, China exported alloy steel plate to the US in a value of 70.26 million dollars.According this arbitration, the United State Customs will charge deposits in cash to Chinese producers of relative products.

These years, countries tend to use trade sactions  to protect domestic trade. But, I don' t think trade saction is a good way for economic. The high-handed measures  will hurt two parties.

Silver lining of labor shortage — Rebar mesh

Rebar mesh can be a silver lining of labor shortage. Instead of hand-tying loose deformed steel bar, welded rebar mesh has tremendous appeal which can save a lot of labor effort. Avoiding most of the labor at the site needed for placing and tying individual bars not only relieves the severe labor shortage we are facing, but also offers a superior and elegant solution where a perfect grid of crossing wires is used.

We can produce a much larger array of grade 80 deformed wire sizes compared to available rebar sizes, enabling the rebar mesh designer to provide precise areas of steel, reducing over-steeling, cutting material costs down.

How to bent screw thread steel bar into U shape?

Screw thread steel bar in small diameters can be bent into U shape, L shape and other shapes through manual force by most people of average strength, while screw thread steel bar in large diameters should be bent by typical machines. Bending steel can be accomplished either through using heat or through using manual force. 


Instructions
1. Determine the dimensions of your bolt. A U-bolt will have two straight legs of equal length connected by a bend. Determine the length of the straight leg of the bolt. Mark the length on the screw thread steel bar and screw a nut on the rod until it reaches the mark.

2. Secure the screw thread steel bar in the vise. Use a vise that is securely mounted to a workbench. Clamp the rod so that the jaws of the vice squeeze the nut, not the threads of the rod.

3. Align the nut so that it is level with the top of the vice. Tighten the vice so that the rod is firmly secured in the jaws of the vice. Do not allow the jaws of the vice to mar the threads of the rod.

4. Bend the rod using using a steel pipe. Slide a steel pipe over the outside of the rod. The pipe should be just slightly larger in diameter than the steel rod. Allow the pipe to slide down until it hits the top of the vice and the nut. The pipe should be one to two feet in length in order to provide sufficient leverage.

5. Wear safety glasses. Grab the pipe and push downward with steady pressure until the screw thread steel bar begins to bend. Continue pushing until the rod is bent into a U-shape.
