Frequently Asked Questions
Which grade should I choose: 201, 304 or 316?
SS201 is commonly selected for cost-sensitive indoor decorative use. SS304 provides balanced corrosion resistance and fabrication performance for general applications. SS316/316L is preferred when higher corrosion resistance is needed. The final grade should be confirmed according to the environment and local project requirements.
Can you produce a non-standard rectangular tube size?
Yes. Custom dimensions, wall thicknesses and lengths can be evaluated according to your drawing, sample, tolerance and required quantity. Tooling or development costs may apply to special profiles.
Can the tubes be cut or processed before shipment?
Yes. Available services include fixed-length cutting, drilling, punching, bending, welding, laser cutting and polishing. Please provide a technical drawing for processed components.
Can I confirm a sample before mass production?
Sample confirmation is available for suitable specifications. For custom sizes or finishes, the sample cost and preparation time will be confirmed after technical review.
What information is required for a quotation?
Please provide material grade, outside size, wall thickness, finish, length, quantity, tolerance or standard, processing requirements and destination port. Clear drawings or reference photos help us quote accurately.
