Shelter is handicap accessible.

Shelter is fully welded with ER70S-2 wire and reinforced with 2x2x1/4” ASTM A36 steel angle frame at every welded joint as well as vertical wall supports every 24” O.C. Shelter anchor angle is double welded to wall panels and vertical wall supports creating a welded three-member connection that is inherently strong. This angle is anchored using either 5/8” diameter wedge or epoxy anchors to new or existing concrete slabs.
