    <p>
      Simpson Strong-Tie<sup>&reg;</sup> connectors, anchors and fasteners
      feature a wide range of materials and coatings designed to meet specific
      performance criteria. It is important to select a material and/or coating
      that is suitable for the intended application and environment based upon
      factors such as corrosion resistance and mechanical properties of the
      material. For more information on selecting connectors, anchors and
      fasteners based upon corrosion resistance, please see
      <a href="/solutions/corrosion">General Corrosion Risks</a>,
