The demand for energy, transportation and petrochemical pipes is not decreasing, and high-performance varieties are growing rapidly. Galvanized rectangular tubes required for the construction and maintenance of energy, transportation, petrochemical and other facilities still occupy a very important position in the steel market demand. In recent years, the demand for new varieties of high-performance galvanized rectangular tubes has increased rapidly, such as high-performance oil well tubes, large-diameter power station boilers 2. The demand for pipeline pipes for transporting oil, natural gas, product oil, coal slurry, mineral slurry and other fluids, especially high-strength pipeline pipes, will increase significantly. 3.With the rapid growth of the construction industry, the demand for high-grade galvanized rectangular tubes for building structures is growing rapidly.Invoicing: by actual weight Delivery Time: 7 days MOQ: 500KG Product name: rectangular steel pipe Surface: Customer's Request Material: ST37/ST45/ST52/25Mn/27SiMn/E355/SAE1026/STKM13C Type: Carbon Steel Tube Steel Grade: Grade B/X42/X52/X60/X70 L245/L290/S320/L360/L390/L415 Color: Customized Color Delivery time: 3-7 Days Item: FOB CIF CFR EXW Supply Ability: 100 Ton/Tons per Week Packaging Details: wooden box or customer requirement Port: qingdao, shanghai port.1.
