Presenter

Presentation Notes

ANSI/HMMA 866 addresses multiple stainless steel applications. Steel can be either type 316 for highly corrosive locations or tyme 304 for moderately corrosive applications. Steel face sheets finishes can vary, but are mainly either #4 satin, #8 mirror or #23B which is the mill finish Steel thickness is 0.042” Core construction is laminated honeycomb or foam. Door edges can be either visible or welded Frame construction: Steel type and finish usually match the door. Steel thickness is 0.053”. Miters are either KD or welded


ANSI/HMMA 866: Stainless Steel

Presenter

Presentation Notes

Both the stainless steel type and finish must be specified. For example, if a high degree of aesthetic appearance and high corrosive resistance are both required, it can be accomplished by the application of a high aesthetic finish to a Type 316 stainless steel constructed door. A complete range of finishes, including #4-satin and #8-mirror, and can be selected and applied to the stainless steel sheet. Alternatively, the stainless sheet may remain unfinished (i.e. #2B-mill finish). The mill finish sheet may be supplied “as is” or may be chemically treated to allow for factory applied prime paint, then field applied finish paint.

• Can improved frame performance

• Use mortar grout

• Plaster grout not recommended

Tech Notes: Grouting Hollow Metal Frames

HMMA 820-TN01-03

Provides clarity and direction on proper methods of jobsite frame grouting

Presenter

Presentation Notes

Tech Note 820-TN01-03 addresses field grouting of frames. Grouting of Hollow Metal Frames is a common practice but can lead to early rusting if the frame is not properly protected or if the wrong grout is used. Key issues to keep in mind: This is a field application – performed by the installing contractor. IT is the contractor’s responsibility that: Frame is properly installed and braced The frame is not used as a forms for grouting Protect the interior surfaces of the frame from anti-freezing agents. Properly protect and clean the frame when cleaning up excessive grout. Due to moisture content, use only mortar grout not plaster grout. Grouting is not recommended for drywall applications. Depending on wall construction, grouting can improve frame durability, sound deadening and anchorage strength.
