MATERIALS
All Metal Roofing offers an extensive range of outstanding materials

All Metal Roofing has spent many years working tirelessly sourcing and implementing the highest standard of materials for our product range. Utilising our vast knowledge of hard metals and their applications, our directors, managers, contractors and design and development teams have forged strong working relationships with world class manufacturing companies to select materials that meet our stringent requirements and those of our clients.

Our extensive range includes traditional standing seam and batten roll, long strip standing seam, rain screen cladding, diamond tiles, shingles and flat-lock cladding, ornamental work, gutters, rainwater pipes and parapet wall capping. We can also provide a full trade package allowing for the associated substrates below the exterior finish to include structural liner trays, insulation, vapour control layers and timber work.

The materials are supplied by companies outstanding in their fields such as: Rheinzink, Follansby, Corus, KME, Falzonal, Luvata, Ugine ALZ, VM Zinc and Novelis.

ALUMINIUM

A silver-white ductile element with a melting point of 660 degrees centigrade, Aluminium is the third most abundant element on the planet, after oxygen and silicone. It is found combined in over 270 different minerals and thanks to its low density, it is resistant to corrosion due to passivation.

Aluminium alloys are most useful in the aerospace, transportation and structural industries and the principal ore of Aluminium is Bauxite. In the roofing and cladding industry, it has a wide variety of uses as compounds of oxides and sulphates. (Atomic Mass: 26.981539 +- 0.0000008u).

COPPER

A reddish-orange coloured element with a melting point of 1,085 degrees centigrade, Copper (from the latin Cuprum) is a ductile metal with very high conductivity and thermal properties. Pure copper is malleable and was originally mined in Cyprus, hence cuprum. Architectural structures built with copper tend to patinate to a blue green or verdigris.

The metal has been used for thousands of years and has been alloyed with various metals for an abundance of uses in all aspects of modern living. In the roofing and cladding industries, copper has been used for guttering and downspouts and principally for roofs, particularly oddly shaped or domed as it is easy to form. (Atomic Mass: 63.546 +- 0.003u).

ZINC

A matt-grey coloured element with a melting point of 419.6 degrees centigrade, Zinc is the 24th most abundant element on earth, with the most common ore, Sphalerite, a zinc sulfide blend. Mined in the US, Asia and Australia using froth floatation, roasting and electricity, it has been alloyed with copper to make Brass since the 10th Century.

Discovered in 1746 by Marggraf, it is principally used to protect iron from corrosion by a hot dip galvanization process. In the roofing and cladding industry, it has both a weatherproofing and aesthetic role as it ages with the building. (Atomic Mass: 65.38 +- 0.0002u).

STAINLESS STEEL

An alloy of iron, other elements and carbon depending on the use and process, Stainless Steel, or Inox steel, possesses carbon, manganese, phosphorus, sulphur, silicone and the principal Chromium. The melting point of Steel is between 1540 and 1400 degrees centigrade. Other elements added to modify the characteristics for different uses are nickel, molybdenum, boron, titanium, vanadium and niobium.

The carbon content in the steel can vary from 0.002 to 2.1% in weight and act as a hardening agent for the iron atoms. The variation in tensile strength, hardness and ductility comes from the amounts of alloying elements used in the process. In the roofing and cladding industries, Stainless Steel has a variety of uses including long life, low maintenance roofing and cladding. (Atomic Mass: Varies depending on the ratio of carbon to metal).

GALVANISED STEEL

The Steel production process, outlined above, is enhanced when a protective zinc coating is added by either an electrochemical, electrodeposition or a hot-dip process is applied. The process, first developed by Italian scientist, Luigi Galvani, with Alessandro Volta found electrochemical properties of zinc by 1800. Today, most production is by hot-dip in a bath of molten zinc.

The most common form of this material is GI or Galvanised Iron, which is used for air ducts and sanitation. In the roofing and cladding industry, Galvanised Steel has the strength of Steel with durable hard wearing anti-corrosion properties ideal for harsh climates. (Atomic Mass: Varies depending on the process involved and the ratio of carbon to metal)
