Main features of Square Steel Beam
Light structure but high strength:
Hollow design reduces weight while maintaining bending and torsion resistance.
scheduled maintenance service
Easy to process: Can be cut, welded, drilled, and adapted to a variety of installation needs.
Corrosion resistance:
Galvanized or stainless steel square tubes are suitable for humid or corrosive environments.
Aesthetics:
The appearance is neat and suitable for exposed occasions (such as decoration, railings).
1. Melting iron ore and other materials in a blast furnace to produce molten steel.
2. The molten steel is then refined and poured into large molds to create individual billets.
3. The billet is heated to a very high temperature and passed through a series of rolling mills to form long, thin strips of steel into the size and shape required for the I-beam.
4. After the steel strip is rolled, it is passed through a machine called a roller straightener to straighten any curves or bends in the steel.
5. Cut the steel strip to the required length for the I-beam.
6. The strip is fed into a machine called a saw, which cuts it into the specific shape required for the I-beam.
7. Weld the individual pieces of steel together to form the finished I-beam.
Key points for quality inspection of square tubes:
Dimensional tolerance:
Check whether the side length and wall thickness meet the standards.
Weld quality (welded tube):
No cracks, incomplete penetration and other defects (ultrasonic flaw detection).
Surface defects:
No rust, pits, or galvanized layer shedding.
Mechanical properties:
Sampling test of tensile strength and yield strength (manufacturer required to provide test report).
Notes on square tube selection:
Material selection:
Galvanized or stainless steel is preferred for outdoor environments; carbon steel thick-walled tubes are required for load-bearing structures.
Dimension matching:
Calculate the side length and wall thickness according to the load to avoid over-design or insufficient strength.
Standard certification:
Ensure compliance with industry standards such as American Standards (ASTM).
Applicable principles:
Prioritize square tubes:
When lightweight load-bearing, rapid construction or complex structural design is required.
Careful selection of square tubes:
Extreme high pressure/high temperature environment (seamless thick-walled tubes or special alloys are required).
