中文简体End Caps
Garage Door End Caps components located on the ends of the sections that allow them to pivot as the garage doors open and close. They also reinforce the section and provide a smooth appearance with no visible hardware.
Fiberglass
Fiberglass garage doors mimic the defined grain texture of wood without the maintenance. They’re less prone to denting and cracking but can break upon serious impact. They typically feature a steel frame covered by sheets of fiberglass with polystyrene insulation. Steel end caps help improve rigidity. They can be painted a wide variety of colors for a look that’s easy to customize.
Steel doors feature a nominal 2” thick door panel construction with foamed-in-place polyurethane insulation. They are available with a wide range of windows and hardware options, including a wind load reinforcement for coastal or high-wind areas. They come with a two-coat, baked-on polyester finish that’s virtually maintenance free and can be repainted to match the trim color of your home.
Steel
A steel section with polyurethane foam insulation chemically bonded to both sides. Solidly bonded to the sections resulting in a strong and long lasting door. Durable, kiln-dried pine wood end blocks ensure a mechanical thermal break and better fastening of the hinges. Lag screws engage 8 threads into the wood, compared to self-tapping screw passing through a steel end cap which only grabs 2 or 3 threads. This improves the overall R-Value of the door, increases strength and makes the door resistant to jets of water in car washes.
Heavy-gauge wraparound end caps trim out door edges for a better appearance, improved strength and to protect the foamed-in-place polyurethane insulation from damage. Optional silent glide nylon rollers and solid steel shafts provide years of smooth, quiet operation. Wind load options available for coastal and high-wind areas.
Composite
Composite garage doors generally feature a wood frame covered with sheets of fiberboard. Better models offer higher-density fiberboard skins and realistic details like overlays and grooves to simulate a real wood door. Cores are filled with polystyrene insulation. Composite garage doors are less prone to denting and cracking than steel, but they can break upon impact. Steel end caps are often used to improve rigidity.
Wood
A steel core is insulated with polystyrene and the surface of each section is covered with embossed sheets of fiberboard to give a more realistic wood grain appearance. Composite doors are less prone to denting and are not subject to corrosion from chemicals used at car washes.
A mechanical thermal break between sections prevents heat transfer, and double-contact bottom weatherstripping is also included for better sealing. 14-gauge steel reinforcement plates are placed inside each section for solidly fastening hinges and struts. Lag screws are used, which engage 8 threads into the kiln-dried pine wood end blocks, compared to a self-tapping screw engaging only 2 or 3 threads into a steel cap.
