Installation Supplies Synthetic Underlayment
Installation Supplies- Fasteners

Fasteners

Our Fasteners are designed specifically to attach metal roof and sidewall panels used in pre-engineered metal building applications. All fasteners come standard with an enhanced corrosion resistant coating. 36 standard colors are available.

  • Exceptional corrosion and weather resistance

  • Conventionally electroplated and painted fasteners will normally resist the corrosion effects of Kesternich testing for 15-20 cycles.

  • Powder-coated finish outperforms the conventional dip-spin applied wet-coatings.

  • Powder is formulated to provide color retention, plus chalk and fade resistance expected of finished building panels.

  • Excellent film hardness. Our powder coated fasteners resist scratches and damage during shipping better than conventionally applied wet paints. The overall toughness and heavier coating thickness of the powder finish provides excellent resistance to the abuses of normal installation.

Installation Supplies- Pop Rivets

Pop Rivets

Our open-ended rivets are designed to attach 2 thin pieces of metal for a low-profile appearance. Applications include metal roofing ridge-caps, roof gutters and downspouts.

  • 304 Stainless Steel, Carbon Steel, & Aluminum are available.

  • Painted #43 Stainless are available to match most architectural panel colors.

  • Rivets come in bags of 100 pieces.

Installation Supplies- Synthetic Underlayment

Synthetic Underlayment

Our synthetic underlayment is a highly engineered coated woven synthetic material that offers a reliable secondary layer of protection under all types of primary sloped roofing material. Unlike felt, its recyclable polyolefin construction doesn’t expand or contract and is inert to mold and mildew growth. It is 100% synthetic and is unaffected by water. It is engineered to lay flat and will not buckle or wrinkle when exposed to temperature and moisture fluctuations on the roof. Unlike oil saturated felts, our synthetic underlayment does not dry out, leach oils in the heat, nor does it become stiff, difficult to roll or crack in the cold.

  • A ridged walking surface with slip resistant coating technology 100% Recyclable

  • Cool light grey surface doesn’t expand or contract

  • 14 x Stronger and 11 times lighter than #30 felt

  • 6 Month UV exposure rating

  • All temperature flexibility (-40 degree F to 240 degree F)

  • Class A Fire – ASTM E108

  • Meets and exceeds ASTM D226

  • Meets Class 4 Hail rating
