Provide a dimensionally consistent square tube specification before agreeing stainless supply.
Side and wall compatibility
The title requests 40×40 and 60×60 sections, while the only wall option spans 1–150 mm. Confirm actual side dimensions and a physically compatible wall rather than treating the entire range as usable with either titled section.
Material and route
304, 201 and 316 appear in the model with broader material references. Select one actual designation and verify the described seamless construction and selected surface against the order requirements.
- Actual stainless designation
- Both section side dimensions
- Compatible wall thickness
- Manufacturing and finish evidence
- Length and inspection criteria
Construction acceptance
Several shapes and processing services are listed without section-specific results. Agree actual supply geometry and tests; building and chemical application wording does not establish structural capacity, pressure performance or validity of every grade and wall combination.
