Profiles & Substrates

 

Fasten-through panels are manufactured to your exact lengths and specifications at HPM’s production facility in Keaau and delivered to your jobsite. They’re fastened with exposed color-matched screws that penetrate the metal roofing and secure to the purlin or sheathing. In general, fasten-through panels are less expensive than Standing Seam panels.

 

HPM manufactures the Standing Seam right on your jobsite using a portable roll-former. This enables each panel to be produced to exact measurements as specified in the field as the contractor installs. Standing Seam panels are fastened using screws or concealed clips and the ribs are engaged by either snapping together or mechanically seaming. Curved and tapered treatments are available to match unique architectural designs. Photovoltaic solar panels can be easily installed on standing seam roofing using clips instead of penetrating screws.
