Ducting is manufactured from 0.8mm to
1.2mm galvanised steel with a Pittsburgh lockform, buttonlock,
crimped, internal capped or a spotwelded construction. Generally,
the materials we use are light gauge 0.56mm to 3mm galvanised steel,
aluzinc, zintec, aluminium and "316" or "304" stainless steel.
If you have different specifications, then we would gladly source
items specific to your needs.
