Explosion Relief


CSM contracted with CB&I/Shaw to supply and install the roofing and siding on a new power plant in Virginia. The design called for an area of explosion relief panels due to the possibility of the stored coal combustion.

The outcome

The explosion relief system we engineered consisted of our metal siding attached to the structural girts with stainless steel cable. Special fasteners are designed to release after being exposed to the pressures during an explosion. Not only does this system prevent the metal panels from becoming projectiles, but it also relieves the pressure – thus minimizing the explosion.
