Technical Data Series

The following is a list of the current Technical Documents available from the Steel Door Institute.

All of our standards are free of charge and available collectively in a single PDF called the Fact File.

Note: All values which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be ± 1/16 in. (1.6 mm). Weight or force shall be ± 2%. Angles shall be ± 2 degrees. Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers.
