Description
Hot Rolled Steel Square Tubing
Hot rolled steel square tubing is a type of cold formed, electric-resistance welded steel tube or cold formed LSAW/SSAW steel tube. The raw materials for hot-rolled square steel tubes are mostly hot-rolled steel coils or hot-rolled steel plates.
Small diameter hot-rolled steel square tubings are mostly manufactured using the ERW steel tube manufacturing process. In the workshop of Yuantai Derun, we refer to hot-rolled steel square tubings with a diameter below 200 * 200mm as small diameter hot-rolled steel square tubings, and those with an outer diameter greater than 200 * 200mm as large diameter hot-rolled steel square tubes.
Type Of Hot Rolled Steel Square Tubes
Hot Rolled steel square tubing devided into 3 types: ERW steel tube, LSAW steel tube, SSAW steel tube and Seamless square steel tubes.
Shape Of Hot Rolled Steel Square Tube

Hot rolled square steel tubes with inner and outer right angles
Round arc R-angle hot-rolled steel square tube
Coating Of Hot Rolled Steel Square Tubes

FAQ:
How To calculate steel square tube weight？
The weight of a square tube can be calculated using the following formula: weight=wall thickness x (side length-wall thickness) x 7.85 x length. It should be noted that the calculated weight is only the theoretical weight, not the actual weight. The actual weight of the Yuantai Derun square tube is the weight measured by weighing.
Why Is yuantai Derun One Of Biggest square steel tube manufacturers In World?
Yuantai Derun is not only the largest square steel tube manufacturer in China.It also ranks first in the world market share of square tubes.
Is Lower steel square tube price Better To Us?
Not necessarily, if we blindly pursue low-priced square tubes, there will definitely be discounts on quality. Therefore, Yuantai Derun never competes with competitors in low-priced prices. On the contrary, our square tubes always prioritize quality and price.
how to cut steel square tube?
The most common and safest cutting method is table type cold cutting saw, and another method is angle grinder cutting. However, regardless of which method of cutting is used, safety precautions need to be taken in advance.
where can i buy square tube steel
？
If the quantity is small, go to a retail metal supermarket to purchase. If the quantity is large, exceeding 25 tons or more, please consider purchasing directly from a square tube factory like Yuantai Derun, which will help you save money.
how to weld square tube steel？
To weld square tube steel, you need a MIG welder, welding helmet, gloves, and safety gear. Here's a simple guide:
Wash the square tube steel to remove dirt, rust, or debris.
Put the tubes together in the right way.
Set up your MIG welder according to the instructions and adjust the welding parameters for the thickness of the steel.
Put on your helmet and gloves.
Start welding by moving the welding gun along the joint. Keep the welding speed and distance from the workpiece consistent. Allow the weld to cool before handling it. Practice safety when welding. If you're not experienced, take a welding class or seek guidance from a professional welder.
can you bend square tube steel
?
You can bend square tube steel in different ways, like with a pipe bender, a hydraulic press, or a bending jig. To bend it, you apply pressure to the material to create the shape or angle you want. It's important to use the right tools and techniques to bend it right and not damage the material. If you don't know how to bend metal, ask a professional or read a guide.
can you paint a500 square steel tube?
Ask a professional painter or hardware store for advice on painting a steel tube. To paint a steel tube, follow these steps:
Clean the surface. Wipe off any dirt, rust, or old paint from the steel tube with a wire brush and cleaning solution.
Sand the surface. Sandpaper makes a good surface for the paint to adhere to.
Apply primer: Use a metal primer and apply one coat to the steel tube.
Paint the tube. Choose a paint for metal and apply it in thin, even coats. Let each coat dry before adding another.
Seal the paint. Once the paint is dry, you can add a clear coat or sealant to protect it and make it smooth.
Follow the manufacturer's instructions for the best results.
