Material note · Iron–carbon alloy family
Steel
Available in many grades with different forming, welding and corrosion behavior.
Where it appears
Structural supports, fabricated forms, tools and contemporary sculpture.
Limits to remember
A generic label is not enough for engineering or welding decisions; the grade and procedure matter.
Care principle
Inspect joints, coatings and contact points as part of a planned maintenance cycle.
A note on identification
Color and texture alone do not prove composition. A real project should use documentation, suitable testing and a qualified professional when material identity affects safety, joining, conservation or structural use.
