75x225mm Welded Straddle Hanger 100ST

Straddle: 100mm

75mm x 225mm Masonry Straddle Joist Hangers are designed for similar applications and installation as the standard Masonry Joist Hangers. The Masonry Straddle hanger is two hangers joined together by a plate on the masonry flange to enable exact alignment of two joists positioned directly opposite each other on either side of a wall or beam. Made from 2.4mm thick Galvanised steel EN 10346 DX51D Z275. Long term safe working load = 3.5 kN.

INSTALLATION of 75x225mm Welded  Straddle Hanger 100ST

• The back plate of the hanger should lie flat against the vertical masonry support.
• Masonry flange should have a minimum of 3 courses (675mm masonry) above.
• Both supporting and above masonry should be allowed to mature before any load is applied.
• Joist should be square cut and sit tight to the back of the hanger - maximum gap permitted is 6mm.
• Nail the side flanges with 30 x 3.75mm galvanised square twist nails or equivalent.
• To provide lateral restraint heavy duty straps should be used.
• The masonry flange should always be securely fixed or adequately embedded and should never be placed in dry slots.
• Use appropriate fixings.
• Always ensure that compatible corrosion resistant fixings are used, i.e. do not use galvanised fixings with stainless steel products or vice versa.
• Use correct strength mortar as per British Standard.
