Troughed Sheets

Additional Details

Aluminium roofing sheets are an ideal solution for all roofing and cladding needs translating into durable, faster and economic construction. 

Some of the benefits of aluminium roofing are:  

• Longer Life
• Light Weight
• Excellent Corrosiion Resistance
• Easy and Fast Fabrication
• High Resale Value
• Better Thermal Insulation

The sheets can be used extensively & economically in Industrial buildings, warehouses, rural housing, poultry cages & as interior partition walls.

Young's Modulus

Young's Modulus or Modulus of Elasticity for Aluminium is 7.0X104Mpa.

Yield Strength

Minimum Yield Strength is 160Mpz for AA3105H18.

Ultimate Tensile Strength (UTS)

UTS for Aluminium is Alloy specific

Coefficient of Linear thermal expansion

Coefficient of Linear thermal expansion for Aluminium (20°C-100°C) is 23.21X10-6/°C

Workability

Everlast Aluminium Sheets can be bent to required shape subject to applicable bend radii for the alloy.

Widths

Hindalco Aluminium sheets are available in following widths:

LAYING AND FIXING

Drill through the crown of the corrugation and fix it to the purlin with aluminium / stainless steel fasteners. fasteners should be done at 3 pitch centre-to-centre for circular corrugated sheets, at 2 pitch centre-to-centre for troughed sheets and ribbed sheets. Every lap should be stiched along the length of the sheet with stitch bolts at maximum 300 mm centre-to-centre. Curved /Flat aluminium washers along with bituminious felt/neoprene or rubber washers are also recommended to be used with fastners and stitch bolts. Avoid direct contact with other building materials such as timber, Portland cement, iron,steel, copper etc. A protective paint or isolation tape is recommended to avoid direct dissimilar material contact. RCC / Steel / timber purlins maybe used. These, however, must be painted with two coats of Aluminium paint preceded by a coat of primer before installation of the sheet.
