IG Timber Frame Lintels
Designed for use in timber frame construction, IG timber frame lintels provide support to the outer leaf to brickwork over openings.
All IG timber frame lintels must be installed with restraining clips and a timber pinch batten to prevent rotation of the lintel during the building stage. Propping may be used to facilitate speed of construction.
IG timber frame restraint clips are supplied free of charge and must be fixed to the timber frame structure by 3.3mm x 50mm galvanised nails. Allowance should be made for the movement of the timber frame structure due to settlement and shrinkage. Lateral restraint clip should be placed at 500mm centres each side of mid span.
IG Timber Frame lintels are manufactured from pre-galvanised mild steel BS EN 10346:2009 DX51D plus Z600 or grade Z275 to BS5977: part 2, 1983 (BS EN 845-2:2003). There is a minimum zinc coating of 600g/m2 galvanising including both sides.
