Our stainless steel rectangular tubes are manufactured using advanced production technology. We use high-quality stainless steel raw materials and adopt processes such as cold drawing, extrusion, welding, and precision machining to ensure that each pipe meets the highest quality standards and precise dimensions. These pipes have the advantages of high flatness, excellent surface finish, and stable mechanical properties, and are suitable for various demanding engineering applications.

We offer a variety of commonly used grades of stainless steel rectangular tubes for you to choose from. Whether you require 304 stainless steel, 316 stainless steel, or other grades, we can meet your specific needs. These stainless steel grades exhibit excellent corrosion resistance, high strength, and good weldability, ensuring long-term stability in various harsh environments.

Precision machining of stainless steel rectangular tubes

Stainless steel rectangular tubes can be precision machined to meet specific requirements. Common precision processing methods include cutting, drilling, welding, bending, etc. These processes can be customized to project needs to ensure accuracy and quality. The following is a detailed introduction to the precision processing technology of stainless steel rectangular tubes:

Step 1. Design and Planning: Before starting precision machining, it is important to perform design and planning activities. Develop detailed processing plans and process flows based on the required size, shape, and specific requirements.
Step 2: Material preparation: Select the appropriate stainless steel material and cut it to the required size and length according to the design specifications.
Step 3. Processing equipment: Choose appropriate processing equipment and tools, such as CNC machine tools, milling machines, drilling machines, lathes, etc. These machines offer high precision and stability to ensure quality in precision machining.
Step 4. Processing operations: Perform different processing operations such as milling, drilling, turning, cutting, etc. according to the design requirements. These operations require tight control of machining parameters such as tool speed, feed rate, and depth of cut to ensure precise dimensions and surface quality.
Step 5. Surface treatment: After precision machining, surface treatment may be required to meet specific requirements. This can include polishing, sandblasting, etc. to improve appearance and enhance corrosion resistance.
Step 6. Inspection and Quality Control: Inspection and quality control are crucial in precision machining processes. Use precision measurement tools and equipment such as calipers, and measurement projectors, and coordinate measuring machines to measure and verify the size and shape of machined parts. This ensures that the parts meet specifications and requirements.
Step 7. Final finishing and packaging: After precision machining, final finishing processes such as cleaning, and removal of cutting oil and contaminants are performed, and then the machined parts are properly packaged to protect them during transportation and storage.

Stainless steel rectangular tubes have a wide range of applications. Whether you need to fabricate handrails, railings, frames, or other structures, our stainless steel rectangular tubes provide a reliable solution. They are highly sought after for their corrosion resistance, high strength, and aesthetics in areas such as building structures, furniture manufacturing, the automotive industry, decoration, and interior design.
