Application

Yuantai Derun attaches great importance to the quality of products, invests heavily in introducing advanced equipment and professionals, and goes all out to meet customers' needs at home and abroad.

Impact test
Structural steel pipe for buildings

Structural steel pipes are often used in sports venue buildings, subway station buildings, commercial buildings, glass curtain wall buildings, landmark high-rise buildings, prefabricated building structures, steel structure buildings, and many other fields.


Usually, structural steel pipes used in buildings must meet corresponding international standards, which are a major type of structural steel pipes with excellent performance.


Small impact testing equipment
Structural Pipe For Mechanical Manufacturing


Mechanical structural steel pipes are often used in automobile manufacturing, agricultural machinery manufacturing, shipbuilding, home appliance manufacturing, fitness equipment manufacturing, furniture manufacturing, gantry crane heavy industry machinery equipment manufacturing, and so on.


Mechanical structural steel pipes usually follow relevant international standards for mechanical structural steel pipes. The tensile strength, yield point, and impact performance of mechanical structural pipes are all excellent.

Greenhouse Structural Steel Tube

Yuantai Derun has 22 Years of Production experience of greenhouse structural steel pipes.

Greenhouse galvanized round pipes, galvanized square pipes, galvanized plastic coated steel pipes, and elliptical galvanized pipes are all the main products of Yuantai Derun.

Yuantai Derun is still the main supplier for the million acre greenhouse project in Feidan, Egypt, with a total order volume of 75000 tons. The desire to grow vegetables in the desert has been fulfilled for the Egyptian people.

shipbuilding steel pipe


Marine structural steel pipes are a large category of steel pipes specifically used in the shipbuilding industry. These types of structural pipes usually strictly comply with relevant marine pipe standards, and many large shipbuilding enterprises are customers of Yuantai Derun.


From the changes in China's shipbuilding industry's share of the world shipbuilding market in the past decade, it can be seen that the proportion of China's shipbuilding industry in the global market is significantly increasing, and China has become one of the important shipbuilding centers in the world.

At present, our products include square tubes for ships, rectangular tubes for ships, round tubes for ships, seamless tubes for ships, and so on. Our BV certification, DNV certification, and ABS certification are very complete. Yuantai Derun is also one of the few enterprises in China that can produce marine structural pipes with qualifications.

Product Testing

CNAS Certified Laboratory

Yuantai Derun attaches great importance to the quality of structural steel pipe products, invests heavily in introducing advanced equipment and professionals, and goes all out to meet customers' needs at home and abroad.

Impact test

Impact test
Impact testing equipment

The impact test of structural steel pipes is divided into the impact test of thin-walled structural steel pipes and the impact test of medium thick walled structural pipes.

Small impact testing equipment
Ultrasonic testing

Non destructive ultrasonic testing exists in two stages: the production process of structural steel pipes and the inspection of finished structural steel pipes.

Yield and tensile testing
Yield and tensile testing

Yield strength testing and tensile testing are usually conducted in one testing equipment.These are also the two most important tests for structural steel pipes.

Chemical composition testing

Chemical composition testing

Chemical composition testing is usually conducted using a direct reading spectrometer. Can quickly provide the composition of the structural tube.

Hardness testing
Hardness testing

Hardness testing is commonly used in structural steel pipes that require hardness applications.

Metallographic analysis
Metallographic analysis

Metallographic analysis is also an important test for the detection of structural steel pipes.

    • How steel is used in buildings and infrastructure?
             The possibilities for using steel in buildings and infrastructure are limitless. The most common applications are listed below.For buildingsStructural sections: these provide a strong, stiff frame for the building and make up 25% of the steel use in buildings.Reinforcing bars: these add tensile strength and stiffness to concrete and make up 44% of steel use in buildings. 

            Steel is used because it binds well to concrete, has a similar thermal expansion coefficient and is strong and relatively cost-effective. Reinforced concrete is also used to provide deep foundations and basements and is currently the world’s primary building material.Sheet products: 31% is in sheet products such as roofing, purlins, internal walls, ceilings, cladding, and insulating panels for exterior walls.Non-structural steel: steel is also found in many non-structural applications in buildings, such as heating and cooling equipment and interior ducting.Internal fixtures and fittings such as rails, shelving and stairs are also made of steel. 

             For infrastructureTransport networks: steel is required for bridges, tunnels, rail track and in constructing buildings such as fueling stations, train stations, ports and airports. About 60% of steel use in this application is as rebar and the rest is sections, plates and rail track.Utilities (fuel, water, power): over 50% of the steel used for this application is in underground pipelines to distribute water to and from housing, and to distribute gas. The rest is mainly rebar for power stations and pumping houses.
