Sunward Steel Buildings are the only metal building with the exclusive Anti-Leak System ®. This system brings you unmatched quality for your building. The secret to the Anti-Leak System is really just a special eye for detail as it comes down to the little things that help keep your building watertight, such as:
Our exclusive Siphon Groove System is a formed gutter on every piece of sheeting for both roof and sidewalls. This disperses water so it doesn’t get inside your building nor between the sheets
Seal Tight Ridge cap that is a factory die formed with a mastic sealant which extends 18 inches on either side of the peak
Premium Fasteners with EPDM rubber washers create a water tight seal and they are color matched to your building!
Mastic sealing in the roof panels keeps water out of your building
16 ga. galvanized angle and closure system at the base of the building that prevents moisture and corrosion from developing
WG-7 closure systems seal roof panels to eaves for a weather tight seal
