Aluminium sections are used for fixed/openable windows, ventilators, partitions, frame work & doors etc. and are most suitable for use to meet architectural designs to relevant works
The aluminium extruded sections (Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile) shall conform to
IS 733 and IS 1285 for chemical composition and mechanical properties.
The stainless steel screws shall be of grade AISI 304.
The permissible dimensional tolerances of the extruded sections shall be as per IS 6477.
The permissible dimensional tolerances of the extruded sections shall be as per IS 6477.
- IS 733 Wrought Aluminium and Aluminium Alloys, Bars, Rods and Sections (For General Engineering Purposes) –Specification.
- IS 1285 Wrought Aluminium and Aluminium Alloy, Extruded Round Tube and Hollow sections (For General Engineering Purposes) – Specification.
- IS 1868 Anodic coating on Aluminium and its Alloys-Specification
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish ) of these product is required to be done before the fabrication work by anodizing/electro coating plants which ensure uniform coating in uniform colour and shades. The extrusions are anodized up to 30 micron in different colours.
The powder used for powder coating (Powder coating is a type of coating that is applied as a free-flowing, dry powder .The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.) shall be Epoxy/polyester powder. The polyester powder shall be applied by electrostatic powder spray method. The thickness of the finished polyester powder coating measured by micron meter shall not be less than 50 micron nor more than 120 micron at any point.
