S/H1A Seismic and Hurricane Tie

S/H1A

On This Page

The versatile S/H1A is designed to resist seismic and wind forces in cold-formed steel applications. These double-sided hurricane ties hold the rafter or truss for high uplift load resistance. The S/H1A is ideal for several proprietary truss chords. It features embossments that add stiffness in crucial areas for improved performance.

Key Features

  • Provide faster installation than using two single-sided straps
  • Provide a connection between the truss or rafter and the wall of the structure that helps resist wind and seismic forces
  • Use also for a variety of general connections where one member crosses another

Material

  • 43 mil (18 ga.)

Finish

  • Galvanized (G90)

Installation

  • Use all specified fasteners.
  • Hurricane ties do not replace solid blocking.
  • S/H1A may be used with proprietary truss sections. Contact material supplier for specific installation details.

Load Table

  1. Tabulated loads based on truss members with yield strength, Fy, of 50 ksi and tensile strength, Fu, of 65 ksi. Reduce tabulated load proportionally for lower truss member steel strength. For example: 43 mil (18 ga.) truss member with a yield strength, Fy, of 33 ksi and a tensile strength, Fu, of 45 ksi is connected to 43 mil top track and wall stud. The adjusted allowable load is then 550 lb. x minimum [33/ 50 or 45/ 65] = 363 lb.
