Heavy Gauge Sub Girt
Heavy gauge sub girts are a critical secondary structural component in modern wall and metal roofing systems. Designed to provide secure attachment points for exterior cladding and rigid insulation, these steel fixations reinforce the building envelope while improving long-term durability and energy performance. At Ottawa Valley Metal Inc., our heavy gauge sub girts are manufactured from premium G90 galvanized steel in thicknesses ranging from 22 gauge to 16 gauge, delivering dependable strength for commercial, residential, agricultural, and modern custom construction projects.
