Stainless steel product
Stainless steel cold rolled coil
Characteristics of stainless steel cold-rolled coils: Good surface, thin thickness, high precision, easy for stamping and bending, suitable for mass production. They are mainly used in products with high requirements for appearance, precision and formability.
Stainless steel cold rolled sheet
The surface is smooth and flat, with thin and uniform thickness, high precision, good hardness, and can be directly used as a decorative surface. Therefore, it is widely used in fields that have high requirements for appearance, precision, and rust prevention.
Stainless steel hot rolled plate
Thick in thickness, high in strength, resistant to impact, inexpensive in price, with a rough surface and oxide layer. Mainly used in industrial scenarios where there is a need for structural load-bearing, high temperature resistance, corrosion resistance, and where the appearance requirements are not strict.
Stainless steel welded pipe
Uniform wall thickness, large diameter, long length, high cost-performance ratio, fast production. Suitable for scenarios with low pressure, emphasis on appearance, using conventional fluids, and requiring large quantities.
Stainless steel seamless precision pipe
Seamless, with extremely high dimensional accuracy, smooth inner and outer walls, uniform wall thickness, and high strength. It is specifically used in places where strict tolerances, sealing performance, cleanliness, and high pressure requirements are required.
Stainless steel seamless industrial pipe
High temperature resistance, corrosion resistance, high strength, good sealing performance. It is mainly used in fluid transportation, high-temperature and high-pressure conditions, chemical industry, mechanical structures and other scenarios with high safety requirements.
Stainless steel bar
Stainless steel bars (round bars, hexagonal bars, square bars, etc.) enjoy core advantages such as corrosion resistance, high strength, easy processing, hygiene and environmental friendliness, and are applied in almost all manufacturing fields including machinery, construction, chemical industry, medical field, and transportation.
Finned tube
Finned tubes (also known as fin tubes) are core components with fins installed on the surface of base tubes such as round tubes and stainless steel tubes. They greatly increase the heat exchange area and strengthen heat transfer, making them a mainstream choice for energy conservation and waste heat recovery.
Stainless steel narrow strip
The stainless steel narrow strip, with its features of high precision, excellent corrosion resistance, easy processing and lightweight, is widely used in fields such as electronics, automobiles, medical equipment, household appliances, hardware, precision machinery, and architectural decoration.
Stainless steel sheets have a wide range of applications in daily life. Household appliances, kitchenware, sinkware, etc. are all excellent market products.
