SRP^TM
Doors & openings

For vertical reinforcement, also referred to as SRP™ Jamb Studs, the most commonly used and recommended practices to use are:

DOORS OR OPENINGS UP TO 1000MM WIDE

V1. Steel SRP™ Stud with a timber Stud [FIGURE 21] or V2. Two Steel SRP™ Studs with a timber insert [FIGURE 21].

OPENINGS WIDER THAN 1000MM

V3. Use two SRP™ Steel Studs together with a timber Stud, fastening the timber and the first adjacent stud with L Brackets top and bottom [see FIGURE 21].

The timber width should match the stud width and height. The timber insert height matches the door jamb height. Where necessary use the L bracket to allow for vertical movement.

The timber and/or steel SRP™ Studs are secured to the top SRP™ Tracks using the permanent fastening holes of the SRP™ L Bracket [FIGURE 1]. For 150mm SRP™ Studs always use two SRP™ L Brackets side by side. If there is significant localised point load above the opening, the fastening of these SRP™ Studs to the top SRP™ Track may need to be avoided, or the use of the slotted hole of the SRP™ L Bracket can be used to allow for movement [see FIGURE 1]. Consult SRP™ and/or a structural engineer for specific design for these situations.

NOTE: Only untreated timber framing should be used in direct contact with any galvanised SRP™ products. If it is unavoidable to use treated timber, a separation barrier between the galvanised SRP™ product and the treated timber should be used.
