Hinges are devices connecting two solid objects that allow for rotation of one object relative to the other. They are widely employed in consumer and commercial applications. Strap hinges are ones where one or both flaps of the hinge have an elongated, narrow profile. They are best used on doors and gates, as the hinge's length offers a better connection between the two parts and takes up relatively little room. Here are some guidelines for selecting the most appropriate strap hinge for one's needs.
Area of application
Choosing a hinge depends significantly on the intended application. Hinges meant for use on industrial storage chests will naturally differ from those used for garden gates. Strap hinges applied to hatches and cabinet doors should be sturdy, relatively small, and low maintenance. In contrast, hinges applied to wrought-iron gates, and front doors may be large ornamental kinds designed to draw the eye and hold the entrance's weight.
Material and finishing
Hinges come in a wide range of materials, though they are universally strong metals capable of holding up a lid or door, such as copper, steel, iron, or brass. The material chosen should fit the purpose--an ornamental hinge for a door, for instance, can be made of forged iron for aesthetics but also given a coat of lacquer for environmental protection. On the other hand, a hinge for a hatch on a ship, which is far more exposed to the elements, requires nothing less than 316 marine-grade stainless steel, corrosion-resistant, and extremely strong long-lasting. Hinges made of ordinary steel for indoor use may also be zinc plated for corrosion protection.
One flap of the hinge is connected to the more massive base body, but the other is connected to the moving part (such as a cabinet or gate door). As the hinge's stability and effectiveness rely on the axis and the flaps themselves capable of holding up the said moving part's weight, they should have a Safe Working Load that exceeds this figure. There are ANSI standards for hinge strength, which becomes a useful tool to ensure the hinge selected is sufficiently heavy-duty to perform effectively. A weak hinge can lead to personal injury and damage to the object it's applied to.
