2. Aluminum as a building material
• Background
• Aluminium is a product with unique
properties, making it a natural partner for the
building industry.
• Thanks to its strength, durability, corrosion
resistance and recyclability, it has become an
essential product for the building industry.
• Fabricated for the fast track construction
3. Applications of Aluminium in
Construction and Building
• Aluminium extruded, rolled, and cast products
• Door & Window frames
• Glazed structures ranging from shop fronts to
large roof superstructures for shopping centres
and stadiums
• Roofing, siding, and curtain walling
• Door handles, catches for windows, staircases,
heating and air-conditioning systems.
• Aluminum Partitions
• Renovation of historic buildings.
4. Aluminium Windows
• Made from extruded sections of aluminium
alloy
• Extrusion process allows for a wide range of
sections
• Sections are mechanically cleated or screwed
at joints and sealed
• Fabricated sections are then coated by various
methods
5. Types of Protective Coating
• Protective coating is done because on
exposure to air, aluminium forms an oxide,
surface coating which is coarse textured light
grey finish which attracts grime, which is
difficult to clean.
• Anodising: It is aluminium oxide coating,
covered with lacquer to protect aluminium
section from alkaline materials
6. Types of Protective Coating
• Polyester powder: Polyester powder is sprayed
on sections and stoved at 200 degree celsius
to form a hard, smooth, durable coating
• Liquid organic coating: acrylic is applied in
liquid form by dip or spray for color, and
stoved at 200 degree celsius to form a hard,
smooth, durable coating
