Some architectural specifications require steel frames to be back-coated with a bituminous coating for corrosion protection or sound control. It is commonly specified to be used in conditions for hollow metal frames that are to be grout filled and when using anti-freezing agents in the plaster or mortar.
Bituminous is a term for a coating or emulsion containing fibrous or non-fibrous asphalt. Other than a few selective uses unrelated to steel frames, it is not readily available. A more modern replacement for this material is automotive undercoating.
Steelcraft does not offer and will not back-coat frames with a bituminous or other type of coating at the factory. It is recommended that this coating be applied either in the distributors shop in the field at time of installation. This coating never fully dries, leaving a dark residue that can be transferred to other parts of the frame.
