Technical specifications for metal bars

Steel

Metal bars (hot-rolled I-profile section steel) manufactured using grade A-37 or grade A-42 steel. On request, we can also use semi-oxidised steel (Corten) or copper-chromium-nickel steel.

Finished supports

Metal bars (I-profile) IPE 330 with the following technical characteristics:

  • Length: 12 m
  • Width: 330 mm
  • Total vane width: 160 mm
  • Rib thickness: 7.5 mm
  • Vane thickness: 11.5 mm
  • Density: 7830 to 7850 kg/m³
  • Elastic modulus (e): 21,000 dan/mm²
  • Rigidity modulus (g): 8200 dan/mm²
  • Yield strength (re): 28 to 45 dan/mm²
  • Tensile strength (r): 40 to 48 dan/mm²
  • Coefficient of thermal expansion: 12x10-6/°c

Treatment of bars

Three coats of paint to protect the bars against corrosion:

  • A minimum of one coat of anti-rust lead-based paint after brushing;
  • One intermediate coat of paint;
  • One topcoat in black.

It is also possible to choose hot-dip galvanising.

These treatment procedures should give the supports an average useful life of 30 years under normal conditions of maintenance.
