Are wedge anchors acceptable for use outdoors?
When using wedge anchors outdoors, it is not uncommon for some corrosion to occur. Stainless steel wedge anchors may even corrode in some specific types of applications. Small amounts of corrosion may not affect the anchors’ holding values. If a large amount of corrosion is suspected, it is imperative that the wedge anchors be inspected and replaced by a professional if needed. Wedge anchors will corrode and may lost some load carrying capacity if they are installed in corrosive areas and exposed to many different types of corrosive materials. The areas and materials which may create a corrosive environment range from pressure treated wood (ACQ), salt water, ocean salt air, fertilizers and exposure to two dissimilar metals. There are numerous variables that make it impossible to predict if or when corrosion may occur in the environment in which the wedge anchors are placed. It is essential that periodic inspections and regular maintenance be scheduled on wegdge anchors used outdoors.
