SS Rectangular Pipe Supplier in India — All Sizes, All Finishes

We stock stainless steel rectangular pipes from 20x10mm up to 200x100mm in wall thicknesses from 0.5mm to 6mm. Popular sizes include 40x20mm, 50x25mm, 60x30mm, 75x50mm, 100x50mm, and 150x75mm. Standard lengths are 6 metres. We maintain ready stock in SS 304, 316L and 202 grades at our Vadodara warehouse for immediate despatch across India. Custom sizes can be manufactured on order with 4-6 week lead time.

The key difference is the aspect ratio. Square pipe has equal sides (e.g. 50x50mm) while rectangular pipe has unequal sides (e.g. 100x50mm). Rectangular sections offer higher moment of inertia in one axis, making them more efficient for beams and applications where load is primarily in one direction. Square pipe provides equal strength in both axes, ideal for columns and multi-directional loading. Both are manufactured to the same ASTM A554 or A312 standards.

Yes. SS 304 and 316L rectangular pipes with adequate wall thickness (typically 2mm and above) are widely used in structural applications. They offer excellent strength-to-weight ratio combined with corrosion resistance, making them ideal for outdoor structures in aggressive environments. For primary structural members, load calculations should be verified by a qualified engineer. We provide section property data including moment of inertia, section modulus, and cross-sectional area for all stock sizes.

We supply SS rectangular pipe in mill finish (2B), hairline or satin finish (No.4, 180-grit directional brush), mirror polish (No.8, 600-grit reflective), bead-blasted (matte texture), and PVD-coated finishes (gold, rose gold, champagne, black). All polished and coated pipes are protected with PE adhesive film. For architectural projects, we can match specific finish textures to your reference sample. Polishing is available on all four faces or selective faces as required.

The theoretical weight formula for SS rectangular pipe is: Weight (kg/m) = [(A + B) x 2 / 3.14159 - T] x T x 0.02491, where A and B are the outer dimensions in mm and T is the wall thickness in mm, and 0.02491 is the density factor for SS 304 (7.93 g/cc). For example, a 100x50mm x 2mm WT SS 304 rectangular pipe weighs approximately 4.55 kg per metre. We provide weight charts for all stocked sizes and can weigh individual pieces on request.

Yes. We are an established exporter of SS rectangular pipe to the Middle East, Africa, Southeast Asia, Europe and South America. All export orders are supplied with complete documentation including mill test certificates, packing lists, commercial invoices, certificates of origin, and fumigation certificates. We pack export orders in wooden cases or bundles with waterproof protection suitable for sea freight. Our GSTIN and IEC codes are active for hassle-free export clearance.
