Metline Industries is India’s leading manufacturer of aluminium flanges, made from high quality hot rolled plates or bars. Our production expertise includes complete range of aluminium seamless extruded pipes, aluminium buttweld fittings and aluminium pipe bends in accordance with ANSI/ASME and DIN standards. All products are supplied with 100% traceability, and copies of manufacturers test certificates to EN 10204 3.1.
At METLINE, aluminium flanges are manufactured from rolled aluminium plates and bars and not from cast aluminium, making them most suitable for special applications. Aluminium flanges are generally supplied without any surface treatment, as the aluminium oxide film formed on the surface of flanges exhibits sufficient resistance to corrosion in normal atmosphere. Aluminium elbows and bends are generally manufactured from 6000 series aluminium pipes which meet the requirements for strength, welding and anodizing.
A combination of various factors including lightness, hardness, good resistance to corrosion, and cost effectiveness makes the use of aluminium flanges an attractive alternative to other materials. We can manufacture aluminium flanges for usage with stainless steel pipes, aluminium pipes or plastic pipes, and also offer special size aluminium flanges manufactured in accordance with customer drawings in aluminium alloys – 6061, 6082, 5052, 5083 and 5086.
Aluminium flanges and aluminium pipe fittings can be produced in shortest lead times to meet the increasing requirements of marine, power generation, oil and gas, paper and pulp manufacturing and general engineering industries.
METLINE offers aluminium seamless pipes in accordance with material specifications of aluminium alloy 5083-O, 6061-T6, 6082, 6063 seamless pipe, extruded to ASTM B241, and the dimensional specifications of ANSI B36.1. Aluminium butt weld fittings are manufactured in accordance to ANSI B16.9 & B16.28, and aluminium flanges to ANSI 16.5.
We complement our manufacturing range of aluminium flanges with ex stock supply of aluminium pipes, custom made and standard size aluminium seamless elbows, aluminium tee’s, aluminium reducers, aluminium end caps, aluminium bends, aluminium buttweld fittings, aluminium nipples, threaded bars, aluminium nuts, aluminium bolts, and other aluminium fasteners.
Our key products include aluminium LR (long radius) and SR (short radius) seamless elbows, aluminium equal/unequal tee, aluminium concentric & eccentric reducers, aluminium end caps, aluminium stub end, ANSI/DIN standard aluminium flanges and aluminium slip on collars.

Products are packaged to ensure that there is no damage during transit. In case of exports, standard export packaging is done in wooden cases. All fittings and flanges are marked with Grade, Lot No, Size, Degree and our trade mark. On special requests we can also, make custom marking on our products.
At METLINE, all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products.
Test Certificates: Manufacturer Test Certificate as per EN 10204 / 3.1B, Raw Materials Certificate, Third Party Inspection Report
