A roof sheet system confirmed with profile, pitch and purlin spacing, not ordered from a colour sample alone.
Profiled roof sheet is light and fast where thick insulation is not required. Colour matters less than pitch, laps, fasteners and gutters. A low pitch or weak flashing leaks before the sheet itself fails.
Send the span direction, pitch, purlin spacing and any lights or vents. Name coastal or high-wind sites so fixing can follow the code. No profile is “universal” without pitch.
Draw the sheet with purlins, ties and knee braces. A profile change often changes spacing. Reinforce and flash openings; do not crop sheets at random.
This page lists what to align. Thickness and coating follow the schedule, not a single size written here.
Tiankai Southeast fabricates marked members from approved drawings and supports erection by mark number. Sizes, loads and delivery follow the confirmed design file and contract; this page does not turn uncalculated tonnage, thickness or time into a promise.
- Fix pitch, purlins and gutters together
- Name high-wind sites
- Stiffen openings before flashing
