Steel

Today, the U.S. Department of Commerce announced its procedures for excluding products from the recently announced tariffs on steel and aluminum product imports.

On March 8, President Trump signed two proclamations to temporarily increase tariffs on imported steel by 25 percent and aluminum by 10 percent. The new tariffs will take effect March 23, but it’s currently unclear how long they will remain in place and which countries they will ultimately be imposed upon.

President Trump is anticipated to slap new tariffs on aluminum and steel later this week, or early next week. Some are wondering, will these be applied to everyone?

Rebuilding a historic church after a ruinous fire was a project not to be forgotten.

While steel consumers will likely continue to take a “wait and see” attitude, the findings the DOC emphasized in their report to the president indicate there may be future trade action to protect domestic producers.  President Trump has until April 11 to act on the DOC’s recommendations.

We are having a house built and on a recent visit we brought along a friend who builds houses for a living. He noticed that the trusses were wet and a bit moldy. The wood seemed warped, brown, and had white splotches on it. We are worried that it would later make the roof uneven. How could we tell how long the trusses have been exposed to the elements? What options do we have from here? Do we request new trusses, or can these be repaired?

Our home caught fire last month and burned partly through a tongue and groove ceiling to the trusses. Some are charred. Our contractor did a moisture meter test. An engineer for the insurance company said the trusses were only smoke damaged & the moisture meter test is invalid (it can be set to read anything). I found one article on charred trusses, but it’s pretty vague. We do not feel safe with the insurance engineer’s assessment because some of the trusses are obviously charred. We hired an engineer who agreed with us.

How do you evaluate whether a metal plate connected truss is still usable after exposure to fire? Are there any recommended tests?

I have a 29 x 72 mobile office with a 2-foot deep wooden truss above the ceiling that a client is required to sprinkler. Is there any way to avoid sprinklering above the gypboard ceiling?

As a forensic engineer who has investigated numerous collapses of wood truss systems, I find your web site an excellent resource on the proper erection of wood trusses. What are your opinions on steel trusses, particularly with regards to installation and bracing? Do you feel that the installation and bracing techniques utilized for wood trusses are applicable to steel trusses? Do you know if that is the general industry standard or are there specific requirements and guidelines for steel trusses? Is there a particular guideline/commentary available for metal trusses?
