Introduction
Steel perimeter trunking systems
Steel perimeter trunking systems
Steel has a mechanical strength that makes it a robust and durable option for public areas where there
is a high footfall. Steel trunking provides specifiers, contractors and end-users with reliable, practical
systems with hard-wearing, clean lines and all the advantages of inherent LSOH and screening
properties. The extra depth provided by Marshall-Tufflex steel perimeter trunking systems offers
increased capacity for power and data services. All earth bondings are ‘friction fit’ to eliminate the need
for unsightly screw fixings.
Recycling and sustainability
• 100% recyclable material.
• Can be recycled many times without loss of quality.
• The steel industry has been recycling for more than 150 years.
• Recycling one ton of steel saves 1,100kilos of iron ore, 630 kilos of coal and 55 kilos of limestone.
• Structural steel typically contains around 95% recycled steel content.
• Recycling facilities are well established.
EMC properties
• An excellent EMC/EMI screening material.
Fire performance
•
Steel trunking systems meet accepted requirements for LSOH.
•
Withstands high temperatures with a melting point of approximately1370°C (2500°F).
•
Type and thickness of any coating needs to be considered as this can affect fire performance.
Environmental
• Steel is very friendly to the environment.
• Compared to other materials it requires relatively low amounts of energy to produce.
• The steel industry has made immense efforts to limit environmental pollution in the last
decades.
• Energy consumption and carbon dioxide emissions have decreased by half of what they were in
the 1960s.
• Dust emissions have been reduced by even more.
