Rectangular hollow sections are the typical choice of load-bearing frames in industrial fabrication, and the SS Square Pipe is the most commonly used material along with ASTM A554 or EN 10296 standards. The US market reports a rising trend of volume for architectural, food processing, and transport infrastructure projects. The product is usually made in sizes from 20x20 mm to 150x150 mm, with wall thicknesses varying between 1.2 and 6 mm. The metal is available in annealed or pickled conditions.
Along with the excellent characteristics of corrosion resistance and weldability, material grades like AISI 304, 304L, 316, and 316L are mostly preferred, while the likes of duplex 2205 have been suggested where higher yield strength is necessary. Tolerances for dimensions are achieved through cold forming and laser welding, and the surface finishing ranges from mill finish to satin 240 grit depending on the customer's visual and hygienic requirements. The section modulus, straightness, and corner radius are the parameters that the engineers frequently check during the design reviews.
Design codes often rely on Eurocode and ASME load cases, thus engineers should be able to synchronize section geometry, weld procedures, and inspection techniques like radiography or dye penetrant testing for the location of critical joints and structural assemblies under service conditions anywhere around the globe.
The successful operation of the assembly is contingent upon the availability of the compatible joining parts. This is especially the case when vibration, thermal cycling or chemical exposure is present. In pressure skids, enclosures, and marine fittings, Stainless Steel Fasteners are the products of choice as per the ISO 3506 or ASTM F593 classifications, and the German distributors are the place where one can get full information on metric thread classes, tensile ratings, and the consistency of heat treatment. The most common items are A2-70 and A4-80 bolts, nuts, and washers that are carefully matched to the parent material so as not to give rise to galvanic
