Supplying Aluzinc for over 40 yrs - Trusted around the world
Menu
Aluzinc, also known as Aluzink, Zincalume or Galvalume, has two metallic constituents which create a corrosion resistance barrier effect – the aluminium present on the surface of the coating along with the sacrificial protection of zinc. The 55% aluminium, 43.4% zinc and 1.6% silicon double sided coating is applied in a continuous hot dip galvanising process that creates the attractive characteristic spangled silver finish, a thin layer of aluminium oxide which forms on the top surface preserves the appearance for many years.
Since 1980 Dobel/SSAB has supplied over 1.5 million square metres of Petrochem Aluzinc to most major chemical and petrochemical plants in some of the harshest environments in the world and not one single metre of product supplied has had to be replaced due to corrosion.
Our Worldwide Service Centre’s thirty-five years experience of supplying Petrochem Aluzinc ensures that no other supplier comes close to our product knowledge or levels of support.
Un-rivalled levels of Aluzinc coil stock in two grades, flat sheet widths up to 1250mm with thickness from 0.4 to 2mm and two ‘industry standard’ profiles.
Strength…in independent testing of Aluzinc pipe cladding an insulated pipe with end caps, clad in 0.4mm thick stucco finish Petrochem ZX profile was hardly even dented when pressure was applied equivalent to someone weighing twenty two stone (139.7 kg) standing on it!
Fire Integrity is of prime concern for many clients…back in June 2000, we had an indepentent testing organization carry out a test to demonstrate that correctly specified Petrochem Aluzinc jacketing will withstand a typical hydrocarbon fire. Petrochem Aluzinc clad insulated pipes where tested alongside stucco aluminium sheet, aluminium foil, PVC and Butyl rubber cladding, a typical hydrocarbon fire does not reach the melting point of steel. Aluminium melts at just 660°C…
SSAB/Aluzinc has a very low corrosion rate, on average a maximum of 0.2 μm – 20% of one micron per annum. Theoretically therefore Aluzinc, under normal environmental conditions has a useful life of more than 100 years – in real use SSAB/Aluzinc has been on test for more than 25 years in a severe marine environment at Dungeness Power Station with no red rust corrosion at any corner, edge or face.
Specified worldwide, Petrochem Aluzinc is the most cost effective, safe, corrosion resistant metal pipework jacketing / cladding for petrochemical insulation protection applications.
Traditional ‘stucco’ embossed Aluzink – known as Dobelshield, is increasingly specified by consultants who are concerned about costs, fire integrity, thermal efficiency and appearance.
