Corrapol-BT Corrugated Bitumen Fixings are an excellent budget choice for waterproof fixings when installing a Corrapol-BT sheet roof. Though they don't make for quite as tight a fit as Corrapol BT Screw Cap Fixings, they're still waterproof and are over 10 times cheaper. They're perfect for temporary structures and ones that won't be exposed to heavy rain.
These fixings come in bags of 100. They are steel nails with plastic caps to protect them from water damage. They are available in four colours, black, brown, green and red. These nails go great with the Corrapol-BT Budget Ridge. If you’re assembling a roof using other Corrapol sheeting types, like Corrapol-GRP, High Profile Stormroof, or Corrapol-PVC, check out Corrapol Clear 60mm Superior Flexible Fixings instead.
