powerful gutter machine
One of the great things about Leafaway is that our gutter machine combines the best features from different types of gutter machines into one cohesive unit.
The Leafaway machine is the only dual-system gutter machine in the industry. We call it a “dual-system” machine, because it first roll-forms our product into a seamless, full size 5” K-style (OGEE) gutter, and then covers the gutter with a debris-shedding shield that features our patented pooling design. With this design, liquid adhesion and gravity draw the water into the gutter, while shedding debris from the roof and preventing structural damage caused by failed gutters.
In addition to producing a quality product, you’ll also see added profit potential, because the machine is designed specifically to offer dual-system flexibility. What we mean by this is that switching from a Leafaway profile to a standard, full size K-style (OGEE) gutter is fast and efficient. Plus, our machine’s three spools allow for color combination flexibility—something no other system can provide.
With Leafaway, our one machine will do it all; just convert and go!
precise chop saw
The Leafaway 15” chop saw allows you to cut 90° angles for end runs, 45° angles for inside and outside corners, and any custom angle you need. It also pivots 90° on a turntable for chopping downspouts or fascia boards. The chop saw also streamlines the process of removing old gutters.

system overview
Supra HD™ SMP coil coating system—manufactured and distributed globally by Continental Coatings Inc. and Yung Chi Paint and Varnish Manufacturing Company Ltd.—is a Silicone Modified Polyester High Durability coil coating system, engineered for high-end metal building product applications and challenging exterior environments that require long life and extended warranty coverage. Supra HD system is formulated with a proprietary state-of-the-art polyester resin and silicone polymer system, which is significantly more resistant to UV radiation and natural weathering than traditional polyester paints. Supra HD uses high-quality, long-lasting organic, ceramic and metallic pigmentation to insure excellent exterior color fastness and coating service life. This system is also available in multiple coats and various specialty high-build systems for custom projects and perforated applications. Supra HD may be applied single coat or over the Universal PU-11 High Molecular Weight Urethane Primer or PU-30 High-Build Urethane Primer Systems for extreme environment warranted building product applications.
application parameters
Supra HD system is designed for trouble-free, high-line speed coil coating line application and has been run worldwide under a very wide range of application parameters and substrate conditions. Standard topcoat DFT is .60-.80 mils, which allows for optimal application consistency, color stability and exterior performance. Supra HD was formulated to provide improved stain resistance and cleanability, as well as scratch resistance and surface toughness, while maintaining the system flexibility required for long term bend line corrosion performance. Supra HD paint film is extra tough and can handle difficult roll-forming, panel stacking and transport conditions. Superior primer corrosion resistance and substrate adhesion provide significantly enhanced protection against wet stack storage problems and cut edge and scratch corrosion.
commercial uses
Supra HD system can be formulated in standard, medium, textured and low gloss/low sheen finishes, and supplied in a wide range but limited color pallet. This premium coating supports an extended warranty and can be applied to a variety of adequately cleaned and treated metal substrates including: Hot Dipped Galvanized, ZnAl, Galfan®, ZAM® and Aluminum. Supra HD can be formulated with COOL ROOF ceramic pigment technology and can be formulated to exceed U.S. Energy Star® requirements. It is most ideal for metal wall panels, industrial and agricultural metal building components, premium rainware, commercial and residential metal roofing, and pre-engineered metal building system applications.
