Installation - Steel Strong-Wall for Timber Frame Racking Resistance.
- Available in three widths: 300mm, 450mm and 600mm.
- Available height ranges: 1900mm to 2700mm.
- At only 89mm wide, it can be fitted into standard 89mm and 140mm deep timber frame panels.
- All fixings and adhesives required for installation are included.
- The Steel-Strong-Wall should be fixed directly to the concrete foundation.
- DO NOT sit the Steel Strong-Wall on a timber sole plate.
- A DPC is required between the Steel Strong-Wall™ panel and the concrete foundation.
- The concrete foundation should be designed by the engineer repsonsible for the structure to accommodate
- the hold down anchors and resist the applied loads.

1a - Position the Steel Strong-Wall on top of the foundations in the required position, ensuring the correct orientation of the wall, with the fixing holes facing internally. Mark the foundation through the holes.
1b - Drill vertical holes to the stated diameter and depth:
SSW300 = Ø22mm x 160mm
SSW450 & SSW600 = Ø28mm x 160mm
1c - Ensure the holes are cleaned thoroughly.
1d - Install the anchor bolts supplied: AT-HP resin with M20 X 210 threaded rod for SSW300 and M24 X 210 threaded rod for SSW450 and SSW600.
2a - Position the Steel Strong-Wall™ over the anchor bolt rods and level by using steel shims and structural grout if required. Plumb and where necessary, provide temporary bracing, which can be adjacent timber frame panels if already installed.
2b - Install nuts and washers and tighten by hand. Once the AT-HP
resin has cured (see cartridge label for cure times) tighten the nut to the recommended torque (M20: 150 Nm torque, using torque wrench with a 30mm socket. M24: 200 Nm torque, 36mm socket). Do not over-tighten nuts as this may lead to premature failure.
2c - Attach vertical timber studs to both sides of the Steel Strong-Wall using the short SDS screws provided.
Note: Where necessary to aid levelling of the wall, steel shims are available to order in widths 300, 450 and 600mm and thicknesses 1, 2 and 3.5mm. Contact Simpson Strong-Tie for details.
3a - The Steel Strong-Wall™ can be secured to the adjacent timber frame wall panels using SDW22300 screws (not supplied), installed from the timber frame side as shown in fig. 3a. the spacing of the SDW screws is to be determined by the engineer responsible for the design structure.
Lateral Capacity of SDW22300 Screw:
BS 5268: 0.9kN (short term) Based on 38mm thick C16 timber frame and 38mm thick Steel Strong-Wall stud. Alternate fastening specification shall be in accordance to engineers instructions.
4a - Connect the top of the Steel Strong-Wall™ to the timber frame structure through the pre-drilled holes in the top plate with the long SDS screws provided. If required, as a height makeup piece, a single solid timber packer (typically LVL) should be inserted between the top of the Steel Strong-Wall™ and the timber frame structure.
4b - Install the head binder over timber frame and the Steel Strong-Wall.
4c - Install insulation on the outer face of the Steel Strong-Wall panel and close off the panel by installing sheathing to the face of the timber studs - thus maintaining continuity in the timber frame construction.Sheathing to be installed with fasteners in accordance with engineers instructions.
