Industry​‍​‌‍​‍‌ fabrication and construction projects depend on the standard stainless products for their strength, alignment, and resistance to corrosion in tough environments. Fastening systems made of SS Threaded Rod undergo ASTM A193, ASTM A320, and ISO 3506 tests ensuring their mechanical and structural loading capabilities thereby meeting the assembly requirements of Singapore.

Threaded rods can be made from austenitic grades 304, 304L, and 316, besides duplex classes for greater yield strength. The common diameters are from M8 to M72 with unified threads ranging from 5/16 inch to 3 inch, which can be rolled or cut to obtain the threading. Heat treatment, passivation, and tensile testing are conducted to achieve class B8, B8M, or equivalent standards in both civil and industrial contexts.

Fastening components have often been combined with the usage of structural tubing systems in the constructions of frames, platforms, and equipment supports. The choice of material considers wall thickness tolerance, surface finish, and weld compatibility to keep the fabrication dimensions accurate. EN 10217 and ASTM dimensional controls are the standards of reference when it comes to international projects that require traceability and inspection documentation.

For​‍​‌‍​‍‌ structural frameworks and architectural supports, which are installed in Saudi Arabia, SS Square Pipe can be offered according to ASTM A554 or EN 10296 standards, with the sizes of the squares ranging from 25 x 25 mm to 150 x 150 mm and the wall thicknesses up to 6 mm. Normally, pipes are produced in 304L and 316L grades for their excellent corrosion resistance, perfect geometry, and long-lasting life. By means of quality control and dimensional inspection, the constant performance of fabricated assemblies under extreme service conditions all over the world is guaranteed and ​‍​‌‍​‍‌checked.
