MEGAMET INDUSTRIES, INC.

M-series Door Frames

These frames are designed for build-wall-to-frame construction for installation in masonry, wood stud, or steel stud walls.

Jamb depths available in 1/8” increments, and a variety of special face, rabbet, and return dimensions, along with specialized stop height are available. M-series frames shall be fabricated from quality grade 16-,14- or 12-guage cold rolled or galvanealed steel (A-60) that meets ASTM A-525 standards.

The face corners are fully welded or knocked down for easy field assembly. Like all other series, frames are die-mitered by computerized turrets. The M-series jambs come with alignment tabs, and the heads have tight mating slots for strong corners and accurate opening dimensions. All mortised hardware shall be prepared for by providing cutouts and reinforcements per the manufacturers’ templates. Standard mortised hardware preps shall have the screw holes tapped; for example, reinforcements for template butts in 7-guage steel, then secured in place with a projection type welder. Strike reinforcements shall be 16-guage prepared for ANSI 115.1.

Steel plaster guards shall be factory installed for all hinge and lock reinforcements. Heavy-duty floor clips spot-welded in place at the bottom of each jamb. Reinforcements in 12-gauge steel shall be provided for surface hardware.

Heavy-duty slip-in or welded-in wall anchors per construction requirements shall be provided with each frame.

C-series Door Frames

These frames are designed for build-frame-to-wall construction for installation in wood-stud or steel-stud sheetrock walls. Jamb depths available in 1/8” increments, and a variety of special face, rabbet, and return dimensions; along with special stop heights are available. C-series frames shall be fabricated from quality grade 16-,14-, or 12-guage cold rolled or galvanealed steel (A-60) that meets ASTM A-525 standards. Steel Door Institute standard SDI-100 will be followed and NAAMM standard HMMA-860-865 will be followed. Computerized turrets die-miter the jambs and heads; gussets are then spot-welded in jambs for strong tight corners. Screw holes provided at head corners and in the face at the bottom of the jamb help finish the field installation. The C-series frames come with an additional back-bend made for slipping over sheetrock walls, therefore, they are shipped knocked down for easy field assembly. Compression type wall anchors wedge the head in place and shall be provided at the top of each jamb.

All mortised hardware shall be prepared for by providing cutouts and reinforcements per the manufacturer’s templates. Standard hardware preps, shall have screw holes tapped for example, reinforcements for template butts, and are in 7-guage steel. Then secured in place with projection type welder. Strike reinforcements shall be 16-guage prepared for ANSI 115.1. Reinforcements in 12-guage steel shall be provided for surface hardware.

MC-series Door Frames

These frames are designed for build-wall-to-frame construction and are a combination of our M-series and our C-series frames for installation in wood stud, steel stud, or masonry type walls. Jamb depths available in 1/8” increments, and a variety of special face, rabbet, and return dimensions; along with special stop heights are available.

MC-series frames shall be fabricated from quality grade 16-, 14-, or 12-guage cold rolled or galvanealed steel (A-60) that meets ASTM A-525 standards.

Steel Door Institute standard SDI-100 and NAAMM standard HMMA-860-865 will be followed.

Like our C-series frames we provide the drywall backbend so the sheetrock wall will slide between studs and throat of the frame. Like our M-series frames, computerized turrets die-miter the jambs with aligning tabs and slots in heads for strong tight corners. The face corners are fully welded or knocked down for easy field assembly. All mortised hardware shall be prepared for by providing cutouts and reinforcements per the manufacturers’ templates. Standard mortised hardware preps shall have the screw holes tapped, for example, reinforcement for the template butts, and is in 7-guage steel, then secured in place with a projection type welder. Strike reinforcements shall be 16-guage prepared for ANSA 115.1. Steel plaster guards shall be factory installed for all hinge and lock reinforcements. Heavy-duty floor clips are notched at corners to provide room for easy installation of sheetrock and are spot-welded in place at the bottom of each jamb. Reinforcements in 12-guage steel shall be provided for surface hardware. Heavy-duty welded-in wall anchors are designed to provide room for the sheetrock to go between the anchor and the back-bend in the throat of the frame.
