Strut is normally made of sheet steel, with a zinc coating (), paint, epoxy, powder coat, or other finish.. Strut channel is also manufactured from stainless steel for use where rusting might become a problem (e.g., outdoors, facilities with corrosive materials), from aluminium alloy when weight is an issue or from fiberglass for very corrosive environments.
The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
For high pressure, flare joints are made by doubling the tube wall material over itself before the bell end is formed. The double flare avoids stretching the cut end where a single flare may crack. Before the flaring step, the end of the tube is compressed axially causing the tube wall to yield radially outward forming a bubble.
The conduit may be coated to prevent corrosion by incidental contact with concrete. Aluminum conduit is generally lower cost than steel in addition to having a lower labor cost to install, since a length of aluminum conduit will have about one-third the weight of an equally-sized rigid steel conduit.

Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...
Springback depends on material properties, influencing the resulting bend angle. [2] Depending on material properties, the sheet may be overbent to compensate for springback. [4] Air bending does not require the bottom tool to have the same radius as the punch. Bend radius is determined by material elasticity rather than tool shape. [2]

Angle plates are made from high quality material (generally spheroidal cast iron) that has been stabilized to prevent further movement or distortion. Slotted holes or "T" bolt slots are machined into the surfaces to enable the secure attachment or clamping of workpieces to the plate, and the plate to the worktable.
