Ezy Jamb is a cold rolled steel doorjamb manufactured from 100% zincanneal steel. Ross Beaton invented it after designing and building two townhouses and decided didn't want to see and timber in the house. He was sick of looking at a corner where there are three doors and thinking it looked like a forest. The Ezy Jamb has many advantages to the building industry in terms of use of material, aesthetics and time spent in installation.

Ezy Jamb's advantages include:

• The jamb assembly can be fully installed in approximately 7 minutes, apart from a finishing scrim (trowelling plaster over edge) coat to set the sections in the wall surface. According to the manufacturers, Ezy Jamb can be installed 15-20 times faster than conventional methods using timber jambs.
• Anyone can install it, which cuts down on the labour costs.
• It eliminates the need for architraves, which saves time, money and is good for the environment.
• Finishing Ezy Jamb with normal paint is considerably quicker than conventional methods of sealing, filling and sanding the timber architrave. The manufacturer estimates it is about 12-15 times faster than conventional methods of painting timber jambs.
• The clean lines of the finished product contribute a modern feel to any building.
• Ezy-Jamb is a fully adjustable assembly to cater for a variety of wall widths.
• You can also use the Ezy-Jamb to design a window architrave.
• Any standard door will fit into the Ezy Jamb frame.

A piece of steel flat has no strength in it, but once bent it has 10 times the strength. The Ezy Jamb is extremely strong because of all the bends and joins in the structure. Also, steel doesn't shrink unlike timber.

The reinforced scrimmed edges overcomes the continual damage of knocks doorjambs are subjected to. It is resilient to dents and normal everyday use.

For years architects have been trying with varying degrees of success to come up with architrave free doorways in order to create clean lines and inconspicuous detail. However if architraves are required the Ezy Jamb can appear as a traditional timber assembly with added durability and a superior finish. According to Ross, a company building a 5 star hotel recently used Ezy Jambs as a frame on all the doors and windows, to cut down on labour costs, and then added a timber architrave over the top, as a design feature.

Ezy-Jamb is manufactured from steel with no toxic building agents, carcinogenic or other harmful substances, and is fully recyclable. Zincanneal was chosen for the Ezy-Jamb because of its moisture resistance and durability.

STEP BY STEP
Ezy Jamb comes packaged in six sections. The sides are perforated which allows the nails and screws to go easily through the steel and also helps the plaster bind over the frame.
1 Ensure the door opening is square.
2 Attach both Ezy Jamb sections to the side of the opening where the door will be hinged. Use a level to plumb the sections and then screw or nail at 200mm intervals. NB: The notched section goes to the top to allow for the head.
3 Position head section with 2mm overlapping the vertical section. Put one screw or nail o hold in place.
4 Hang the door in position leaving about 2mm clearance from the top and the hinged side. Once square, fasten the head section into position with a similar gap.
5 Insert the remaining vertical jamb section leaving a similar clearance. Surface mount the striker plate into position to align with the latch.
