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?

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.

Does the NFPA sprinkler standard address sprinkler loading? If so, how and where do I buy it? What other information do you have on sprinkler loading? How do other truss companies price jobs for sprinkler loading the plans do not include a sprinkler layout or even say what size/type of sprinkler system will be used?

We have a local builder wishing to use floor trusses with a 2-hour assembly. I have shown him the 2-hour design on pages 17-27 of the second edition of SBCA’s Metal Plate Connected Wood Truss Handbook. Is this assembly UL approved? If so, what is the design number?

I have been hired by an insurance company to determine the extent of damage to roof trusses exposed to fire. How much fire damage compromises the structural integrity of the truss?

The Gypsum Association “Fire Resistance Design Manual” (GA-600-12) lists file RC2601 with two layers of 5/8 in. gypsum wallboard (GWB) on wood joists.

I am a building inspector and I have a question on information provided on truss design drawings. What does the uplift reaction number represent? Some manufacturers are very specific and state “to provide for mechanical connection of the truss to the top plate with a connector capable of withstanding a specific load.” Others simply list the uplift reaction with no further information. These are the ones that have caused a debate as to what the number actually represents.
