FEATURES

We manufacture manhole covers in first quality aluminium in two formats: plain and refillable.
We are also developing other models with a hardening heat treatment and lids with sliding surface finish.

RATES


Casing covers or cast aluminum logs suitable for installation indoors

Watertight aluminum casing covers in refillable and smooth format.

Usually used as Anti-odor, they prevent leakage of liquids, protect electrical connections, etc … by fixing with screws + vulcanized EPDM rubber gasket.

Available in sizes from 200 x 200 to 1000 x 1000 mm in smooth or solderable format.

Recommended for installation in markets, industrial pavilions, garages, commercial premises, restaurants with industrial kitchens, etc …

Aluminum has physical properties that withstand corrosion with total guarantee.

*It is not the same with materials such as galvanizing or pvc that are oxidized, broken, etc … Well by the manufacturing process where welding (galvanized) and the properties of the material itself or by the quality of own material , Being in this case both contaminants.

Physical properties of aluminum:

  • Aluminum is a chemical element, with symbol Al and atomic number 13. It is a non-ferromagnetic metal.
  • It is the third most common element found in the terrestrial crust.
  • Aluminum compounds make up 8% of the earth’s crust and are present in most rocks, vegetation and animals.
  • In the natural state it is found in many silicates (feldspar, plagioclase and micas).
  • As the metal is extracted only from the mineral known as bauxite, it is first processed into alumina by the Bayer process and then metal aluminum by electrolysis.
  • This metal has a combination of properties that make it very useful in materials engineering, such as its low density (2700 kg / m³) and its high resistance to corrosion.
  • Suitable alloys can significantly increase their mechanical strength (up to 690 MPa).
  • It is a good conductor of electricity and heat, it is easily machined and very cheap.
  • For all this, since the middle of the XX century, the metal most used after steel.
