G-2020, G-2023, G-2323 Steel Polyurethane-Injected Sectional Overhead Garage Door

Features and Benefits

INSULATION 

• R-16

SMOOTH STEEL FINISH 

• 23-gauge or 20-gauge steel, provides a bending resistance 15% greater than 26-gauge steel, for better resistance to impact and vandalism. 

• Highly corrosion-resistant with galvanized steel having a minimum of G60 zinc coating (180 g/m2 ). 

HIGH-PRESSUREINJECTED POLYURETHANE 

• Stronger and more energy-efficientinsulation 

• Solidly bonded to the steel sheetsproviding a section that is resistantto flexion. 

INTERLOK™TRIPLE-CONTACT JOINTS 

• Sections are strengthened by 2 steelwalls joined together with mechanicalinterlocking joints which are more solidthan just two bonded walls. 

• Their mechanical thermal breaks aremore efficient compared to thermalbreaks made with glue. 

• Triple-contact joints provide 2 timesmore weathertightness than thoseof the competition. 

METAL REINFORCEMENTPLATES 

• Provide stronger fastening for hingesand struts. These 14-gauge plates are2 times thicker than 20-gauge platesused by other manufacturers. 

WOOD END BLOCKS 

• Provide a thermal break that is moreeffective than steel end caps whichform a thermal bridge. 

• As structural elements of the sections,the kiln-dried pine wood end blocksare installed at the outer ends of thesection. They are stronger thaninsulation covered with a steel cap. 

LAG SCREW SYSTEM 

• Provides much better fastening ofthe end hinges. The lag screws engage8 threads into the wood, compared toa self-tapping screw going througha steel end cap engaging only about2 or 3 threads.
