Structural Steel Loads – Colors?

Military forces tend to paint things more than civilian organisations, l think it is partly to keep the manpower busy during peacetime, also high standards of maintenance.

Tony Thompson wrote a blog entry on structural steel loads, and you can find it at:

modeling the SP: Search results for structural steel

The MS Open Car Loads books have several photos of steel loads.

You might also be seeing an unpainted load of fabricated steel on the way to the galvanizer.  Fabricated steel in our era might have been primed with red lead for shipment. and was less likely to be finish painted before arrival at destination.

Bob,

 

While I don’t know if the practice dates back to the timeframe that you model, the US Navy has been using pre-construction primer on steel plate since at least 1980.

Structural Steel Loads – Colors?

I’ve seen models of structural steel loads that were painted, usually what appeared to be flat black but sometimes other colors.

Did various steel mills paint the structural steel products or were they usually left unpainted when shipped?

Thanks.

Raw structural steel is almost never painted (stuff like I beams or H beams etc) but fabricated steel loads
could be painted or unpainted - I have photos of both. Depends what it is for and whether it is a 'final' product
item or is an intermediate item used to make something else.

Attached is a shot of unpainted fabricated steel.

In my experience the "raw" steel from the steel mill is unpainted, the finished product from the Steel Fabricator will
have been sandblasted and at least primed, sometimes it gets a finish coat.
