Many of the existing Building Stars were used for, almost exclusively, a structural reason. These Stars have a tendency to fail after many years in place due to the embrittlement of low grade / no grade cast iron. Also, keep in mind, that some of the Stars being sold elsewhere today should actually be classified as "strictly decorative, not for structural use."
Structural Star Building Retaining Washers (Structural Retaining Stars) are
domestically manufactured in the USA. Often referred to as
Seismic Earthquake Washers or Century Star Washers, our washers have an architecturally accurate historic pattern, and are used as anchor plates or wall washers that are connected to a tie rod or bolt on exterior walls of masonry buildings for structural reinforcement, used to brace the masonry wall against lateral bowing. They are available with a five or six point star design in
hot galvanized cast ductile iron or may be custom-ordered in aluminum or bronze.
Structural Stars are exclusively manufactured from
Ductile Iron to ASTM 65-45-12, which is virtually a 'semi-steel' and hot galvanized and are
weldable. In comparison to unrated Cast Iron products, there may be a risk when used inappropriately in structural applications.
Star Washers are also specified in plans as Gib Plates, Hurricane Bolts, Pattress Plates, Masonry Restraints and Tie Backs.
We can provide you with all of the accessories such as rods, nuts, washers, plates and turnbuckles which you may require to complete the project.
Most Stars have a
flat back and a 7/8" ID. The
Hot Galvanized recommended accompaniments are : 3/4
Ogee Washer, 3/4
USS Flat Washer, 3/4-10
Heavy Hex Nut and 3/4-10 x 6'
Threaded Rod. The 13" Stars require 1" hardware. All Stars have a thickness of 7/8", with the exception of the 13" Stars, which have a thickness of 2-1/2".
The most popular size is
7-1/2" (5 Point), although 5-1/2" (6 Point), 7" (5 Point), 9" (6 Point), 10-1/2" (5 Point), and 13" (5 Point) are also readily available.
