Overview
The 70 series uses the same construction logic as the 50 series — inside glazing, one-piece corner keys and a top-pin mullion joint — on a deeper 70 mm frame. The extra frame depth gives more space for the glazing rebate and for the gasket line, and produces a deeper shadow line on the facade.
It is the specification most often chosen where the elevation needs a stronger frame presence than the 50 series but a thermal break is not required. Glazing is 5 + 12A + 5 with Xinyi original glass, and hardware is a full set of Bojue stainless steel.
Square or arc glazing beads, a fixed guardrail and a three-section fly screen are available on the same frame.
